(a) At the beginning of the various parts, subparts, and sections, a more specific application is generally given for the particular portion of the text involved. This application sets forth the types, sizes, or services or vessels to which the text pertains, and in many cases limits the application of the text to vessels contracted for before or after a specific date. As used in this subchapter, the term “vessels contracted for” includes not only the contracting for the construction of a vessel, but also the contracting for a material alteration to a vessel, the contracting for the conversion of a vessel to a cargo or miscellaneous vessel, and the changing of service or route of a vessel if such change increases or modifies the general requirements for the vessel or increases the hazards to which it might be subjected.
§ 90.05-7 Ocean or unlimited coastwise vessels on inland and Great Lakes routes.
(a) Vessels inspected and certificated for ocean or unlimited coastwise routes shall be considered suitable for navigation insofar as the provisions of this subchapter are concerned on any inland routes, including the Great Lakes.
§ 90.05-10 Application to vessels on an international voyage.
(a) Except for yachts and fishing vessels and as provided in paragraphs (b), (c), and (d) of this section, the regulations in this subchapter that apply to a vessel on an “international voyage” apply to a vessel that –
(1) Is mechanically propelled and of at least 500 gross tons; and
(2) Is engaged on a voyage –
(i) From a country to which the International Convention for Safety of Life at Sea, 1974, (SOLAS 74) applies, to a port outside that country or the reverse;
(ii) From any territory, including the Commonwealth of Puerto Rico, all possessions of the United States and all lands held by the United States under a protectorate or mandate, whose international relations are the responsibility of a contracting SOLAS 74 government, or which is administered by the United Nations, to a port outside the territory or the reverse; or
(iii) Between the contiguous states of the United States and the states of Hawaii or Alaska or between the states of Hawaii and Alaska.
(b) The regulations that apply to a vessel on an “international voyage” in this subchapter do not apply to ships engaged on a voyage solely on the Great Lakes and the St. Lawrence River as far east as a straight line drawn from Cap de Rosiers to West Point, Anticosti Island, the 63d Meridian;
(c) The Commandant or his authorized representative may exempt any vessel on an international voyage from the requirements of this subchapter if the vessel –
(1) Makes a single international voyage in exceptional circumstances; and
(2) Meets safety requirements prescribed for the voyage by the Commandant.
(d) The Commandant or his authorized representative may exempt any vessel from the construction requirements of this subchapter if the vessel does not proceed more than 20 nautical miles from the nearest land in the course of its voyage.

§ 90.05-25 Seagoing barge.
(a) Each seagoing barge, as defined in 46 CFR 90.10-36, is subject to inspection and certification; except that a seagoing barge is exempt from those requirements if it is unmanned for the purposes of operating or navigating the barge, and carries neither a hazardous material as cargo nor a flammable or combustible liquid, including oil, in bulk quantities of 250 barrels or more.
(b) In applying the laws and regulations to manned seagoing barges, one criterion for invocation of safety standards is the description of seagoing barges by relative size in gross tons. When it is determined by the Commandant that the gross register tonnage for a particular manned seagoing barge, which is attained by exemptions, reductions, or other devices in the basic gross tonnage formulation, will circumvent or be incompatible with the application of specific safety requirements in the regulations in this subchapter for a manned seagoing barge of such physical size, the Commandant shall prescribe the regulations to be made applicable to such seagoing barge. When the Commandant determines that the gross register tonnage is not a valid criterion for the invocation of safety requirements based on relative size, the parties involved will be informed of the determination and of the regulations applicable to such manner seagoing barges, and before being permitted to operate such seagoing barges, compliance therewith shall be required. Endorsements or notations on the seagoing barge’s certificate of inspection may be made as appropriate.

In main machinery spaces, all portions of such spaces must be capable of being reached by at least 2 streams of water, each of which must be from a single length of hose from separate outlets; however, this requirement need not apply to shaft alleys containing no assigned space for the stowage of combustibles. Fire hydrants must be numbered as required by § 97.37-15 of this subchapter.
(e) All parts of the fire main located on exposed decks must either be protected against freezing or be fitted with cut-out valves and drain valves so that the entire exposed parts of such piping may be shut off and drained in freezing weather. Except when closed to prevent freezing, such valves must be sealed open.
(f) The outlet at the fire hydrant must be limited to any position from the horizontal to the vertical pointing downward, so that the hose will lead horizontally or downward to minimize the possibility of kinking.
(g) Each fire hydrant must have at least one length of firehose, a spanner wrench, and a hose rack or other device for stowing the hose.
(h) Firehose must be connected to the outlets at all times. However, on open decks where no protection is afforded to the hose in heavy weather, or where the hose may be liable to damage from the handling of cargo, the hose may be temporarily removed from the hydrant and stowed in an accessible nearby location.

To provide appropriate and adequate standards, the Coast Guard with the assistance of the National Offshore Operations Advisory Committee, and following the provisions of the Administrative Procedures Act, developed Subchapter IA, Regulations for Mobile Offshore Drilling Units, 46 CFR Parts 107-109 and amendments to 46 CFR Subchapters “F”, Marine Engineering Regulations, and “J”, Electrical Engineering Regulations. These regulations, published in
3. Discussion. a. This NVIC elaborates the “grandfather provisions” of 46 CFR 107.211 and 107.215 in applying Subchapter IA to the approximately 150 existing ocean-going U.S. flag mobile offshore drilling units. “Existing” Mobile Offshore Drilling Units are those vessels which have been contracted for before the effective date of the regulations including:
(1) Units in Service.
(2) Units under construction.
(3) Units contracted for which are to be constructed and delivered prior to January 1, 1981.
b. Existing uncertificated mobile drilling units of which there are approximately 92 of the bottom bearing configuration, i.e., jack-up and submersible types, have not previously been required to comply with vessel inspection regulations. Some units have met the load line requirements of Subchapter “E” for International Voyages. Many of the older units are not classed by a classification society. Bottom bearing units operating on the Outer Continental Shelf of United States have been required to meet the safety requirements of 33 CFR Subchapter “N” as artificial islands. On January 3, 1979, existing bottom bearing units are subject to the “grandfather provisions” in § 107.211(c) of Subchapter IA.
c. Existing certificated mobile offshore drilling units, for the purposes of this NVIC, are column-stabilized and ship-shape types of which approximately 58 are currently certificated, or have made application for an original Certificate of Inspection or intend to make application for an original inspection for certification under 46 CFR Subchapter “I” on the basis of the unit being contracted for prior to the effective date of the new regulations. These units may continue to meet the structural, equipment, material and arrangement standards which were applicable to the hull, engineering, electrical and industrial systems when the units were contracted for. In addition they must meet the provisions of d.(1), d.(4)(d), d.(7)(b), d.(8), d.(9), d.(10)(b), d.(11) and d.(12) of paragraph 3 of this NVC in accordance with § 107.215(c)(2) of Subchapter IA.
d. Inspection Provisions for Existing Uncertificated Units. The intent of the “grandfather” provisions of this NVIC for existing uncertificated units is to ascertain through inspection that the material condition of the unit and its equipment meet reasonable levels of safety. To this end, the following determinations will be made:
• The design, construction and arrangements of the hull, machinery electrical and industrial systems do not reveal manifestly unsafe aspects.
• There is no excessive deterioration of the hull structure or equipment foundations.
• There are no intrinsic fire or explosion hazards.
• There are no personnel hazards such as unguarded moving machinery, potential electrical shock conditions or lack of handrails.
• The unit is seaworthy and exhibits satisfactory stability.
(1) General. (a) Repairs and minor alterations to hull structure or equipment may be made to the same standards as the original installation. However, new installations or major alterations which affect vessel or personnel safety shall meet the applicable standards of Subchapter IA.
(b) Existing items of safety equipment not meeting the applicable specifications or requirements set forth in Subchapter IA may be continued in service as long as they are maintained in good working order to the satisfaction of the OCMI. Such safety equipment and installations requiring extensive repairs shall be replaced and shall meet the applicable specifications and requirements of Subchapter IA.
(c) The OCMI has discretion to accept alternatives or equivalents which meet the established standards, and to give special consideration to departures from the regulations when it can be shown that special circumstances warrant such departures.
(2) Plan Submittal. (a) For units not classed by the American Bureau of Shipping or other recognized classification society, (see 46 CFR 108.109) the OCMI must have sufficient plans and information submitted to him which will describe such things as the unit’s size, construction, configuration, arrangement of tanks, decks and spaces; and the machinery and electrical installation. In addition, the OCMI may require submittal of any additional data he considers necessary in order to proceed with the original inspections.
(b) For units classed by the American Bureau of Shipping or other recognized classification society, the plans and information described in Subchapter IA § 107.305 (a), (b), (v), and (ii) and a general description of the machinery and electrical installation shall be submitted to the OCMI for information. The OCMI may accept continued classification as proof of structural, mechanical, and electrical sufficiency. However, the OCMI may require additional plans and information if necessary.
(3) Hull Structure. (a) No structural changes will be required unless manifestly unsafe conditions exist.
(b) Existing uncertificated units must be drydocked or have a special examination in lieu of drydocking as required by 46 CFR, 107-261.
(c) Achievement of one compartment subdivision is not required where extensive modification of the original design would be necessary; however, watertight integrity of the hull and structural boundaries must be maintained. Bulkheads and decks designed to be watertight must be maintained as such where they are penetrated by pipes, electrical cable, reach rods, ventilation systems, etc.
(4) Stability. (a) The stability of each existing unit will be reviewed by the Coast Guard. The plans indicated in 46 CFR Subchapter IA § 107.305(q) through (u-l) must be submitted to the cognizant OCMI or Merchant Marine Technical Office.
(b) Lightship data from a Coast Guard witnessed and approved stability test is required for each existing, uncertificated unit. Alternatively other evidence of lightship values will be considered on a case by case basis.
(c) In general, compliance with the intact stability standards of 46 CFR Subchapter IA, §§ 108.303 through 108.309 is required. Where existing units were designed to a lesser standard of stability than that specified in §§ 108.303 through 108.309, some relaxation based on proven past performance may be granted at the discretion of the OCMI and limiting conditions, if any, set forth in the operating manual. In no case will the minimum wind speed for adequate stability be reduced below 50 knots.
(d) An operating manual shall be prepared for each unit. Each operating manual must contain the information indicated in 46 CFR Subchapter IA, § 109.121(d) and be submitted to the cognizant OCMI or Merchant Marine Technical Office for review.
(5) Load Line. (a) All units are required to obtain and maintain a valid Load Line Certificate. The structure and stability of the unit must be proven adequate for the voyages and areas of operation intended.
(b) The American Bureau of Shipping or other recognized classification society will issue Load Line Certificates and conduct initial and annual load line surveys. Coast Guard and the American Bureau of Shipping inspections may be conducted simultaneously, but it is the owner’s responsibility to arrange coordinated inspection schedules.
(c) The structural review conducted by the American Bureau of Shipping or other recognized classification society for load line assignment may be accepted by the Coast Guard as proof of structural adequacy of the hull.
(d) The stability review must be completed prior to issuance of a Load Line Certificate. The Coast Guard will inform the American Bureau of Shipping or other recognized classification society of the results of the stability review, and will indicate any stability limitations to be placed on the Load Line Certificate.
(e) Freeboard calculations for self-elevating units with barge type hulls will be made in accordance with 46 CFR, Part 42. The bow height requirements of 46 CFR 42.20-70 may be relaxed to approximately 33% of the normal requirement for barge shapes moving at speeds less than 6 knots. No relaxation of the addition to freeboard for deficiency in sheer is allowed. The freeboard for units other than self-elevating units with barge type hulls will be based upon compliance with the intact and damage stability standards applicable at the time the unit was contracted for.
(f) All units delivered after the date of this NVIC regardless of contract date, must obtain a Load Line Certificate as soon as operationally feasible.
(6) Route and Operating Area Limitations. (a) Units classed by the American Bureau of Shipping or other recognized classification society for ocean service generally will be certificated by the Coast Guard for ocean routes.
(b) Unclassed units which have proven structural and stability adequacy by continued safe operation in a specific geographic area, such as the Gulf of Mexico, will be limited by the Certificate of Inspection and Load Line Certificate to that area. To qualify for an unlimited oceans route, such a unit must be reviewed for adequacy of the structure and stability by the Coast Guard and meet the Load Line requirements of d. (5) above.
(c) Any unit which intends to move or operate outside the geographical area indicated on the Certificate of Inspection must receive prior approval from the OCMI.
(7) Fire Protection. (a) Structural fire protection. All units must meet the provisions of § 108.123, Insulation of Combustible Materials and § 108.127, Storage Lockers for Combustibles. All existing interior stairways which are open at each end must be enclosed at one level. On units where wood was utilized in the construction of accommodation spaces, each space must be equipped with a smoke or heat detector either battery powered or operating on the AC power supply. All detectors must have the Underwriters Laboratories, Inc., label (UL) or the Factory Mutual Laboratories (FM) label.
(b) Fire Extinguishing Systems. Systems and equipment must be provided which will meet or be equivalent to the applicable specifications and provisions required by Subchapter IA. Installed fire extinguishing systems, which provide equivalent or greater protection than systems required by Subpart E, Subchapter IA may be continued in use as long as they are in good material condition and will function as designed. Where practicable, existing washdown systems may be utilized as the firemain. Where wood was utilized in the construction of accommodation spaces, the applicable requirements of 46 CFR Subchapter IA, Table 108.495(a) should be doubled.
(8) Lifesaving Equipment. (a) Each unit must have lifesaving equipment (lifeboats and davit launched liferafts) for 200 percent of the total persons allowed on board. Except for submersible type units, the installation of lifeboats for 100 percent of the persons (on board) is required in accordance with 46 CFR 108.503 of Subchapter IA. Consideration will be given to those units where existing arrangement and structure do not provide sufficient room for installation of the lifeboats or where the added weight of the lifeboats, davits and winches will materially reduce the variable load capacity of the unit. In such cases, davit launched inflatable liferafts with a combined personnel capacity of the required lifeboats, and a rescue boat approved by the OCMI may be acceptable equivalents. Submersible type units may substitute Coast Guard approved throw over type inflatable liferafts and an approved rescue boat for the required lifeboats.
(b) For the second part of the total 200 percent primary lifesaving requirement, lifeboats installed in accordance with 33 CFR, Subchapter “N” Part 144 or Coast Guard approved life floats may be retained as provided for in 3.d(1)(b) of this Circular. They will be considered collectively with the Coast Guard approved liferafts for calculating the amount of equipment to provide for 100 percent of personnel on board.
(c) Adequate access to all lifesaving equipment must be provided.
(9) Cranes. (a) Plan approval will not normally be required of any crane which conforms to the specifications of the manufacturer as originally installed. A rated load test as described in § 107.260 of Subchapter IA will be required unless the crane has been load tested while under certification by an approved certifying authority as provided for in 46 CFR 107.258. Prior to the rated load test, the crane should be identified by manufacturer and model number to determine that the correct load rating chart is being used. The owner must submit to the OCMI details and calculations of any alterations to a crane which were accomplished without manufacturer’s documentation in order to verify the rated load of the crane.
(10) Electrical. (a) Multiple power sources do not require an emergency generator; however, storage batteries or approved relay-controlled battery operated lanterns are required to be installed for the emergency lighting system and provide 12 hours of lighting.
(b) Electrical equipment installed in Class I, division 1 and 2 locations, as defined in Subchapter IA, § 108.170 must be of a suitable type and in good material condition.
(11) Unfired Pressure Vessels. (a) Unfired pressure vessels built and stamped in accordance with Section VIII of the ASME Code may be continued in service as long as they remain in satisfactory condition. At the original and subsequent inspections for certification, ASME Code pressure vessels must be tested and examined in accordance with the requirements in 46 CFR 61.10-5.
(b) Unfired pressure vessels which cannot be identified as being constructed to any recognized standard may be continued in service provided that no obvious defects are noted. These pressure vessels shall be hydrostatically tested to one and one half times the working pressure. For pressure vessels that can not be reasonably hydrostatically tested, nondestructive testing may be used to verify the pressure vessels condition for continued serviceability. These pressure vessels will then be stamped with a Coast Guard identification number and periodically tested and examined in accordance with the requirements in 46 CFR 61.10-5.
(12) Marine Sanitation Devices. (a) All units must meet the provisions of 33 CFR Part 159, Coast Guard Marine Sanitation Devices Regulations. The discharge requirements are compatible with the OCS Orders of the U.S. Geological Survey.
4. Action. a. The owner of each existing certificated unit must provide the cognizant OCMI a proposed plan to accomplish the requirements in paragraph 3. c. of this NVIC within 60 days from the effective date of the regulations. Most items should be approved at the unit’s next inspection for certification; however, where major equipment installations are concerned, the owner may be allowed up to two years to comply with the requirements from the time the OCMI completes his assessment of the proposals.
b. Application for Original Inspection for Certification. Not later than sixty days from January 3, 1979, application for original inspection for certification of all existing uncertificated units, shall be submitted to the appropriate OCMI. The plans or descriptive data specified in paragraph 3.d(2) of this NVIC along with a proposed plan to bring the unit into compliance should, if possible, be submitted with the application for inspection. If not feasible to assemble all required information in this time frame, an estimated date of submittal shall be indicated on the application. Arrangements should be made to commence the original inspection for certification with due consideration for the unit’s operating situation.
c. To the extent possible the same inspection team will conduct the inspection of all existing uncertificated units in a geographical area. It may be advantageous to conduct the original inspection in conjunction with an impending special or periodic survey, drydocking or availability period. Units under construction will receive primary consideration by the OCMI for the allocation of time and personnel so that any problems can be identified while the unit is in the most advantageous situation to apply corrections.
d. The variety of designs and arrangements presented by existing uninspected MODU’s makes it impractical to prescribe detailed standards for all existing units. The procedures followed to implement this NVC must provide the necessary flexibility. Items which must be taken into consideration in applying this NVIC are listed below. Categorizing units into groups to which the same items apply will be of value during the inspection process. These items are:
• Type
• Builder
• Model
• Date build
• Classed by ABS or other classification society
• Load Line assignment
• Operating history (including geographical areas)
• Present location
e. Issuance of the Original Certificate of Inspection. The intent of the original inspection of existing uncertificated units is to identify and commence correction of any unsafe conditions and/or equipment deficiencies and to issue the unit an original Certificate of Inspection. A reasonable period of time will be permitted to correct minor deficiencies. Those items directly affecting personnel safety and health will require immediate attention to correct the unsafe condition. Extensive deficiencies, such as those involving structural aspects or equipment may require up to two years to remedy. Additional times may be allowed if repair facilities are not available to coastal areas adjacent to the unit’s area of operation. Where manifestly unsafe conditions are found, the OCMI may require that the unit discontinue operations until such conditions are corrected. If the owner or operator feels aggrieved by the decision of the OCMI, the appeals procedures of 46 CFR 2.01-70 are applicable.
f. Questions concerning this NVIC should be referred to the Commandant (CG-CVC).

§ 111.10-3 Two generating sources.
In addition to the emergency power sources required under part 112 of this chapter, each self-propelled vessel and each mobile offshore drilling unit must have at least two electric generating sources.
§ 111.10-4 Power requirements, generating sources.
(a) The aggregate capacity of the electric ship’s service generating sources required in § 111.10-3 must be sufficient for the ship’s service loads.
(b) With the ship’s service generating source of the largest capacity stopped, the combined capacity of the remaining electric ship’s service generating source or sources must be sufficient to supply those services necessary to provide normal operational conditions of propulsion and safety, and minimum comfortable conditions of habitability. Habitability services include cooking, heating, air conditioning (where installed), domestic refrigeration, mechanical ventilation, sanitation, and fresh water.
(c) The capacity of the ship’s service generating sources must be sufficient for supplying the ship’s service loads without the use of a generating source which is dependent upon the speed or direction of the main propelling engines or shafting.
(d) Operating generators must provide a continuous and uninterrupted source of power for the ship’s service load under normal operational conditions. Any vessel speed change or throttle movement must not cause a ship’s service load power interruption.
(e) Vessels with electric propulsion that have two or more constant-voltage generators which supply both ship’s service and propulsion power do not need additional ship’s service generators provided that with any one propulsion/ship’s service generator out of service the capacity of the remaining generator(s) is sufficient for the electrical loads necessary to provide normal operational conditions of propulsion and safety, and minimum comfortable conditions of habitability.
(f) A generator driven by a main propulsion unit (such as a shaft generator) which is capable of providing electrical power continuously, regardless of the speed and direction of the propulsion shaft, may be considered one of the ship’s service generating sets required by § 111.10-3. A main-engine-dependent generator which is not capable of providing continuous electrical power may be utilized as a supplemental generator provided that a required ship’s service generator or generators having sufficient capacity to supply the ship’s service loads can be automatically brought on line prior to the main-engine-dependent generator tripping off-line due to a change in the speed or direction of the main propulsion unit.

(d) Switching. In the design of a control, interlock, or indicator circuit, all practicable steps must be taken to eliminate all but one source of power in an enclosure. If the control functions make it impracticable to energize a control interlock or indicator circuit from the load side of a motor and controller disconnect device and the voltage of the control, interlock, or indicator circuit is more than 24 volts, there must be one of the following alternative methods of switching:
(1) Each conductor of a control, interlock, or indicator circuit must be disconnected from all sources of potential by a disconnect device independent of the motor and controller disconnect device.

§ 112.01-1 Purpose.
The purpose of this subpart is to define types of emergency lighting and power systems.
§ 112.01-5 Manual emergency lighting and power system.
A manual emergency lighting and power system is one in which a single manual operation, such as the manual operation of a switch from an “off” to an “on” position, is necessary to cause the emergency power source to supply power to the emergency loads.
§ 112.01-10 Automatic emergency lighting and power system.
An automatic emergency lighting and power system is one in which a reduction in potential from the ship’s service power and lighting plant causes the emergency power source to supply power to the emergency loads.
§ 112.01-15 Temporary emergency power source.
A temporary emergency power source is one of limited capacity that carries, for a short time, selected emergency loads while an emergency power source of larger capacity is being started.
§ 112.01-20 Final emergency power source.
A final emergency power source is one that functions after the temporary emergency power source is disconnected.
Subpart 112.05 – General
§ 112.05-1 Purpose; preemptive effect.
(a) The purpose of this part is to ensure a dependable, independent, and dedicated emergency power source with sufficient capacity to supply those services that are necessary for the safety of the passengers, crew, and other persons in an emergency and those additional loads that may be authorized under paragraph (c) of this section.
(b) No load may be powered from an emergency power source, except:
(1) A load required by this part to be powered from the emergency power source;
(2) A bus-tie to the main switchboard that meets § 112.05-3; and
(3) Emergency loads that may be necessary to maintain or restore the propulsion plant, such as control systems, controllable pitch propellers, hydraulic pumps, control air compressors, and machinery necessary for dead-ship start-up.
(c) Other loads may be authorized by the Commanding Officer, Marine Safety Center (MSC), to be connected to the emergency source of power to provide an increased level of safety in recognition of a unique vessel mission or configuration. When these loads are authorized, the emergency power source must –
(1) Be sized to supply these loads using a unity (1.0) service factor; or
(2) Be provided with automatic load shedding that removes these loads and operates before the emergency generator trips due to overload. The automatic load shedding circuit breakers must be manually reset.

PART 115 – INSPECTION AND CERTIFICATION
Subpart A – General Provisions; Certificate of Inspection
§ 115.1 Preemptive effect.
The regulations in this part have preemptive effect over State or local regulations in the same field.
§ 115.2-115.99 [Reserved]
§ 115.100 When required.
(a) A vessel to which this subchapter applies may not be operated without having on board a valid U.S. Coast Guard Certificate of Inspection.
(b) Except as noted in § 115.114 of this part, each vessel inspected and certificated under the provisions of this subchapter must, when any passengers are aboard during the tenure of the certificate, be in full compliance with the terms of the certificate.
(c) If necessary to prevent delay of the vessel, a temporary Certificate of Inspection may be issued pending the issuance and delivery of the regular Certificate of Inspection. The temporary certificate must be carried in the same manner as the regular certificate and is considered the same as the regular Certificate of Inspection which it represents.
(d) A vessel on a foreign voyage between a port in the United States and a port in a foreign country, whose Certificate of Inspection expires during the voyage, may lawfully complete the voyage without a valid Certificate of Inspection provided the voyage is completed within 30 days of expiration and the certificate did not expire within 15 days of sailing on the foreign voyage from a U.S. port.
§ 115.103 Description.
The Certificate of Inspection issued to a vessel describes the vessel, the route(s) that it may travel, the minimum manning requirements, the survival and rescue craft carried, the minimum fire extinguishing equipment and life jackets required to be carried, the maximum number of passengers and total persons that may be carried, the number of passengers the vessel may carry in overnight accommodation spaces, the name of the owner and managing operator, any equivalences accepted or authorized by the Commandant or any Officer in Charge, Marine Inspection (OCMI) in accordance with § 114.540 or § 114.550 of this subchapter and such other conditions of operations as may be determined by the cognizant OCMI.
§ 115.105 How to obtain or renew.
(a) A Certificate of Inspection is obtained or renewed by making application on Form CG 3752, “Application for Inspection of U.S. Vessel,” to the Coast Guard OCMI of the marine inspection zone in which the inspection is to be made. Form CG-3752 may be obtained at any U.S. Coast Guard Sector Office or Marine Inspection Office.
(b) The application for initial inspection of a vessel being newly constructed or converted must be submitted prior to the start of the construction or conversion.
(c) The construction, arrangement, and equipment of each vessel must be acceptable to the cognizant OCMI as a prerequisite of the issuance of the initial Certificate of Inspection. Acceptance is based on the information, specifications, drawings and calculations available to the OCMI, and on the successful completion of an initial inspection for certification.
(d) A Certificate of Inspection is renewed by the issuance of a new Certificate of Inspection.
(e) The condition of the vessel and its equipment must be acceptable to the cognizant OCMI as a prerequisite to the Certificate of Inspection renewal. Acceptance is based on the condition of the vessel as found at the inspection for certification.
§ 115.107 Period of validity for a Certificate of Inspection.
(a) A Certificate of Inspection is valid for 1 year for vessels carrying more than 12 passengers on international voyages.
(b) A Certificate of Inspection is valid for 5 years for all other vessels.
(c) A Certificate of Inspection may be suspended and withdrawn or revoked by the cognizant OCMI at any time for noncompliance with the requirements of this subchapter.
§ 115.110 Routes permitted.
(a) The area of operation for each vessel and any necessary operational limits are determined by the cognizant OCMI, and recorded on the vessel’s Certificate of Inspection. Each area of operation, referred to as a route, is described on the Certificate of Inspection under the major headings “Oceans,” “Coastwise,” “Limited Coastwise,” “Great Lakes,” “Lakes, Bays, and Sounds,” or “Rivers,” as applicable. Further limitations imposed or extensions granted are described by reference to bodies of waters, geographical points, distance from geographical points, distances from land, depths of channel, seasonal limitations, and similar factors.
(b) Operation of a vessel on a route of lesser severity than those specifically described or designated on the Certificate of Inspection is permitted unless expressly prohibited on the certificate of Inspection. The general order of severity of routes is: oceans, coastwise, limited coastwise, Great Lakes, lakes, bays and sounds, and rivers. The cognizant OCMI may prohibit a vessel from operating on a route of lesser severity than the primary route a vessel is authorized to operate on if local conditions necessitate such a restriction.
(c) Non-self-propelled vessels are prohibited from operating on an oceans, coastwise, limited coastwise, or Great Lakes route unless the Commandant approves such a route.
(d) When designating a permitted route or imposing any operational limits on a vessel, the OCMI may consider:
(1) Requirements of this subchapter for which compliance is based on the route of the vessel;
(2) The performance capabilities of the vessel based on design, scantlings, stability, subdivision, propulsion, speed, operating modes, maneuverability, and other characteristics;
(3) The suitability of the vessel for night-time operations; and
(4) The suitability of the vessel for use in all environmental conditions.
§ 115.112 Total persons permitted.
The cognizant Officer in Charge, Marine Inspection (OCMI) determines the total number of persons permitted to be carried on a vessel. In determining the total number of persons, the OCMI may consider the total weight of passengers, crew, and variable loads; stability restrictions and subdivision requirements of the vessel; the vessel’s route, general arrangement, means of escape, and lifesaving equipment; minimum manning requirements; and the maximum number of passengers permitted in accordance with § 115.113 of this subpart.
§ 115.113 Passengers permitted.
(a) The maximum number of passengers permitted must be not more than that allowed by the requirements of this section, except as authorized by the OCMI under paragraph (d) of this section.
(b) The maximum number of passengers permitted on any vessel may be the greatest number permitted by the length of rail criterion, deck area criterion, or fixed seating criterion described in this paragraph or a combination of these criteria as allowed by paragraph (c) of this section.
(1) Length of rail criterion. One passenger may be permitted for each 760 millimeters (30 inches) of rail space available to the passengers at the periphery of each deck. The following rail space may not be used in determining the maximum number of passengers permitted:
(i) Rail space in congested areas unsafe for passengers, such as near anchor handling equipment or line handling gear, in the way of sail booms, running rigging, or paddle wheels, or along pulpits;
(ii) Rail space on stairways; and
(iii) Rail space where persons standing in the space would block the line of vision of the credentialed individual operating the vessel.
(2) Deck area criterion. One passenger may be permitted for each 0.9 square meters (10 square feet) of deck area available for the passengers’ use. In computing such deck area, the areas occupied by the following must be excluded:
(i) Areas for which the number of persons permitted is determined using the fixed seating criteria;
(ii) Obstructions, including stairway and elevator enclosures, elevated stages, bars, and cashier stands, but not including slot machines, tables, or other room furnishings;
(iii) Toilets and washrooms;
(iv) Spaces occupied by and necessary for handling lifesaving equipment, anchor handling equipment or line handling gear, or in the way of sail booms or running rigging;
(v) Spaces below deck that are unsuitable for passengers or that would not normally be used by passengers;
(vi) Interior passageways less than 840 millimeters (34 inches) wide and passageways on open deck, less than 710 millimeters (28 inches) wide;

Subpart F – Hull and Tailshaft Examinations
§ 115.600 Drydock examination, internal structural examination, and underwater survey intervals.
(a) The owner or managing operator shall make a vessel available for drydock examinations, internal structural examinations, and underwater surveys required by this section.
(b) If your vessel is operated on international voyages subject to SOLAS requirements, it must undergo a drydock examination once every 12 months unless it has been approved to undergo an underwater survey (UWILD) per § 115.615 of this part. If the vessel becomes due for a drydock examination or an internal structural examination during the voyage, it may lawfully complete the voyage prior to the examination if it undergoes the required examination upon completion of the voyage to the United States but not later than 30 days after the examination is due. If the vessel is due for an examination within 15 days of sailing on an international voyage from a United States port, it must undergo the required examination before sailing.
(c) If your vessel is operated on other than international voyages and does not meet the conditions in paragraph (d) of this section, it must undergo a drydock and internal structural examination as follows unless it has been approved to undergo an underwater survey (UWILD) per § 115.615 of this part:
(1) A vessel that is exposed to salt water more than three months in any 12 month period since the last examination must undergo a drydock examination and an internal structural examination at least once every two years; and
(2) A vessel that is exposed to salt water not more than three months in any 12 month period since the last examination must undergo a drydock examination and an internal structural examination at least once every five years.
(d) Whenever damage or deterioration to hull plating or structural members that may affect the seaworthiness of a vessel is discovered or suspected, the cognizant OCMI may conduct an internal structural examination in any affected space, including fuel tanks, and may require the vessel to be drydocked or taken out of service to assess the extent of the damage, and to effect permanent repairs. The OCMI may also decrease the drydock examination intervals to monitor the vessel’s structural condition.
(e) For a vessel that is eligible per § 115.625 of this part and the owner opts for an alternate hull examination with the underwater survey portion conducted exclusively by divers, the vessel must undergo two alternate hull exams and two internal structural exams within any five-year period. If a vessel completes a satisfactory alternate hull exam, with the underwater survey portion conducted predominantly by an approved underwater remotely operated vehicle (ROV), the vessel must undergo one alternate hull and one internal structural exam, within any five-year period. The vessel may undergo a drydock exam to satisfy any of the required alternate hull exams.
§ 115.610 Scope of drydock and internal structural examinations.
(a) A drydock examination conducted in compliance with § 115.600 of this part must be conducted while the vessel is hauled out of the water or placed in a drydock or slipway. During the examination all accessible parts of the vessel’s underwater body and all through hull fittings, including the hull plating, appendages, propellers, shafts, bearings, rudders, sea chests, sea valves, and sea strainers shall be made available for examination. Sea chests, sea valves, and sea strainers must be opened for examination. The accuracy of draft or loading marks, if required by § 122.602 of this subpart, must be verified if not already verified at construction or a previous drydock examination.
(b) An internal structural examination conducted in compliance with § 115.600 of this part may be conducted while the vessel is afloat or out of the water and consists of a complete examination of the vessel’s main strength members, including the major internal framing, the hull plating, voids, and ballast, cargo, and fuel oil tanks. Where the internal framing or plating of the vessel is concealed, sections of the lining, ceiling or insulation may be removed or the parts otherwise probed or exposed so that the inspector may be satisfied as to the condition of the hull structure. Fuel oil tanks need not be cleaned out and internally examined if the marine inspector is able to determine by external examination that the general condition of the tanks is satisfactory.
§ 115.615 Underwater Survey in Lieu of Drydocking (UWILD).
(a) The Officer in Charge, Marine Inspection (OCMI), may approve an underwater survey instead of a drydock examination at alternating intervals if your vessel is –
(1) Less than 15 years of age;
(2) A steel or aluminum hulled vessel;
(3) Fitted with an effective hull protection system; and
(4) Described in § 115.600(b) or (c) of this part.
(b) For vessels less than 15 years of age, you must submit an application for an underwater survey to the OCMI at least 90 days before your vessel’s next required drydock examination. The application must include –
(1) The procedure for carrying out the underwater survey;
(2) The time and place of the underwater survey;
(3) The method used to accurately determine the diver’s or remotely operated vehicle’s (ROV) location relative to the hull;
(4) The means for examining all through-hull fittings and appurtenances;
(5) The condition of the vessel, including the anticipated draft of the vessel at the time of survey;
(6) A description of the hull protection system; and
(7) The name and qualifications of any third party examiner.
(c) If your vessel is 15 years old or older, the cognizant District Commander, may approve an underwater survey instead of a drydock examination at alternating intervals. You must submit an application for an underwater survey to the OCMI at least 90 days before your vessel’s next required drydock examination. You may be allowed this option if –
(1) The vessel is qualified under paragraphs (a)(2) through (4) of this section;
(2) Your application includes the information in paragraphs (b)(1) through (b)(7) of this section; and
(3) During the vessel’s drydock examination, preceding the underwater survey, a complete set of hull gaugings was taken and they indicated that the vessel was free from appreciable hull deterioration.
(d) After this drydock examination required by paragraph (c)(3) of this section, the OCMI submits a recommendation for future underwater surveys, the results of the hull gauging, and the results of the Coast Guards’ drydock examination results to the District Commander for cognizant review.
§ 115.620 Description of the Alternative Hull Examination (AHE) Program for certain passenger vessels.
The Alternative Hull Examination (AHE) Program provides you with an alternative to a drydock examination by allowing your vessel’s hull to be examined while it remains afloat. If completed using only divers, this program has four steps: the application process, the preliminary examination, the pre-survey meeting, and the hull examination. If the vessel is already participating in the program or if a remotely operated vehicle (ROV) is used during the program, the preliminary exam step may be omitted. Once you complete these steps, the Officer in Charge, Marine Inspection (OCMI), will evaluate the results and accept the examination as a credit hull exam if the vessel is in satisfactory condition. If only divers are used for the underwater survey portion of the examination process, you may receive credit for a period of time such that subsequent AHEs would be conducted at intervals of twice in every five years, with no more than three years between any two AHEs. The OCMI may waive an underwater survey in accordance with § 115.655(d) provided that the interval does not exceed five years between any two underwater surveys. If an underwater ROV is used as the predominate method to examine the vessel’s underwater hull plating, you may receive credit up to five years. At the end of this period, you may apply for further participation under the AHE Program.
The expected hull coverage when using an ROV must be at least 80 percent.
§ 115.625 Eligibility requirements for the Alternative Hull Examination (AHE) Program for certain passenger vessels.
(a) Your vessel may be eligible for the AHE Program if –
(1) It is constructed of steel or aluminum;
(2) It has an effective hull protection system;
(3) It has operated exclusively in fresh water since its last drydock examination;
(4) It operates in rivers or protected lakes; and
(5) It operates exclusively in shallow water or within 0.5 nautical miles from shore.
(b) In addition to the requirements in paragraph (a) of this section, the Officer in Charge, Marine Inspection (OCMI) will evaluate the following information when determining your vessel’s eligibility for the AHE Program:
(1) The overall condition of the vessel, based on its inspection history;
(2) The vessel’s history of hull casualties and hull-related deficiencies; and
(3) The AHE Program application, as described in § 115.630 of this part.
(c) When reviewing a vessel’s eligibility for the AHE program, the OCMI may modify the standards given by paragraph (a)(5) of this section where it is considered safe and reasonable to do so. In making this determination, the OCMI will consider the vessel’s overall condition, its history of safe operation, and any other factors that serve to mitigate overall safety risks.
§ 115.630 The Alternative Hull Examination (AHE) Program application.
If your vessel meets the eligibility criteria in § 115.625 of this part, you may apply to the AHE Program. You must submit an application at least 90 days before the requested hull examination date to the Officer in Charge, Marine Inspection (OCMI) who will oversee the survey. The application must include –
(a) The proposed time and place for conducting the hull examination;
(b) The name of the participating diving contractor and underwater remotely operated vehicle (ROV) company which must be accepted by the OCMI under § 115.650;
(c) The name and qualifications of the third party examiner. This person must be familiar with the inspection procedures and his or her responsibilities under this program. The OCMI has the discretionary authority to accept or deny use of a particular third party examiner using the criteria established in 46 CFR 114.400;
(d) A signed statement from your vessel’s master, chief engineer, or the person in charge describing the vessel’s overall condition, level of maintenance, known or suspected damage, underwater body cleanliness (if known), and the anticipated draft of the vessel at the time of the examination;
(e) Plans or drawings that illustrate the external details of the hull below the sheer strake;
(f) A detailed plan for conducting the hull examination in accordance with §§ 115.645 and 115.650 of this part, which must address all safety concerns related to the removal of sea valves during the inspection; and
(g) A preventative maintenance plan for your vessel’s hull, its related systems and equipment.
§ 115.635 Preliminary examination requirements.
(a) If you exclusively use divers to examine the underwater hull plating, you must arrange to have a preliminary examination conducted by a third party examiner, with the assistance of qualified divers. The purpose of the preliminary examination is to assess the overall condition of the vessel’s hull and identify any specific concerns to be addressed during the underwater hull examination.
(b) If you use an underwater ROV as the predominate means to examine your vessel’s hull plating, a preliminary examination and the participation of a third party examiner will not be necessary.
(c) The preliminary examination is required only upon the vessel’s entry or review into the AHE program.
§ 115.640 Pre-Survey meeting.
(a) You must conduct a pre-survey meeting to discuss the details of the AHE procedure with the Officer in Charge, Marine Inspection (OCMI). If you exclusively use divers to examine the underwater hull plating, the third party examiner must attend the meeting and you must present the results of the preliminary examination. If you use an underwater remotely operated vehicle (ROV) as the predominate means to examine the vessel’s hull plating, then a representative of the ROV operating company must attend the pre-survey meeting and address the underwater ROV’s capabilities and limitations related to your vessel’s hull design and configuration.
(b) A vessel owner, operator, or designated agent must request this meeting in writing at least 30 days in advance of the examination date.
(c) The pre-survey meeting may be conducted by teleconference, if agreed to in advance by the OCMI.
§ 115.645 Alternative Hull Examination (AHE) Procedure.
(a) To complete the underwater survey you must –
(1) Perform a general examination of the underwater hull plating and a detailed examination of all hull welds, propellers, tailshafts, rudders, and other hull appurtenances;
(2) Examine all sea chests;
(3) Remove and inspect all sea valves in the presence of a marine inspector once every five years;
(4) Remove all passengers from the vessel when the sea valves are being examined, if required by the Officer in Charge, Marine Inspection (OCMI);
(5) Allow access to all internal areas of the hull for examination, except internal tanks that carry fuel (unless damage or deterioration is discovered or suspect), sewage, or potable water. Internal sewage and potable water tanks may be examined visually or by non-destructive testing to the satisfaction of the attending marine inspector; and
(6) Meet the requirements in § 115.650 of this part.
(b) A marine inspector may examine any other areas deemed necessary by the OCMI.
(c) If the AHE reveals significant deterioration or damage to the vessel’s hull plating or structural members, the OCMI must be immediately notified. The OCMI may require the vessel be drydocked or otherwise taken out of service to further assess the extent of damage or to effect permanent repairs if the assessment or repairs cannot be completed to the satisfaction of the OCMI while the vessel is waterborne.
§ 115.650 Alternative Hull Examination (AHE) Program options: Divers or underwater ROV.
To complete your underwater survey, you may use divers or an underwater remotely operated vehicle (ROV).
(a) If you use divers to conduct the underwater survey, you must –
(1) Locate the vessel so the divers can work safely under the vessel’s keel and around both sides. The water velocity must be safe for dive operations;
(2) Provide permanent hull markings, a temporary grid system of wires or cables spaced not more than 10 feet apart and tagged at one-foot intervals, or any other acoustic or electronic positioning system approved by the OCMI to identify the diver’s location with respect to the hull, within one foot of accuracy;
(3) Take ultrasonic thickness gaugings at a minimum of 5 points on each plate, evenly spaced;
(4) Take hull plating thickness gaugings along transverse belts at the bow, stern, and midships, as a minimum. Plating thickness gaugings must also be taken along a longitudinal belt at the wind and water strake. Individual gaugings along the transverse and longitudinal belts must be spaced no more than 3 feet apart;
(5) Ensure the third party examiner observes the entire underwater examination process;
(6) Record the entire underwater survey with audio and video recording equipment and ensure that communications between divers and the third party examiner are recorded; and
(7) Use appropriate equipment, such as a clear box, if underwater visibility is poor, to provide the camera with a clear view of the hull.
(b) You may use an underwater ROV to conduct the underwater survey. The underwater ROV operating team, survey process and equipment, quality assurance methods, and the content and format of the survey report must be accepted by the Officer in Charge, Marine Inspection (OCMI) prior to conducting the survey. If you choose this option, you must –
(1) Locate the vessel to ensure that the underwater ROV can operate effectively under the vessel’s keel and around both sides;
(2) Employ divers to examine any sections of the hull and appurtenances that the underwater ROV cannot access or is otherwise unable to evaluate; and
(3) If the OCMI determines that the data obtained by the ROV, including non-destructive testing results, readability of the results, and positioning standards, will not integrate into the data obtained by the divers, then a third party examiner must be present during the divers portion of the examination.
§ 115.655 Hull examination reports.
(a) If you use only divers for the underwater survey portion of the Alternative Hull Examination (AHE), you must provide the Officer in Charge, Marine Inspection (OCMI), with a written hull examination report. This report must include thickness gauging results, bearing clearances, a copy of the audio and video recordings, and any other information that will help the OCMI evaluate your vessel for a credit hull exam. The third party examiner must sign the report and confirm the validity of its contents.
(b) If you use an underwater remotely operated vehicle (ROV) as the predominate means to examine the vessel’s underwater hull plating, you must provide the OCMI with a report in a format that is acceptable to the OCMI, per § 115.650(b) of this part.
(c) The OCMI will evaluate the hull examination report and grant a credit hull exam if satisfied with the condition of the vessel. If approved and you exclusively use divers to examine the hull plating, you may receive a credit hull exam to 36 months. (Underwater examinations are required twice every 5 years). If approved and you use an underwater ROV as the predominant means to examine the underwater hull plating, you may receive a credit hull exam up to 60 months (5 years).
(d) At least 60 days prior to each scheduled underwater exam, the owner may request a waiver from the OCMI if:
(1) A satisfactory exam has been completed within the last three years;
(2) The conditions during the last exam allowed at least 80 percent of the bottom surface to be viewed and recorded; and
(3) The results of the last exam indicated that an extended interval is safe and reasonable.
§ 115.660 Continued participation in the Alternative Hull Examination (AHE) Program.
(a) To continue to participate in the AHE Program, vessel operators must conduct an annual hull condition assessment. At a minimum, vessel operators must conduct an internal examination and take random hull gaugings internally during the hull condition assessment, unless waived by the Officer in Charge, Marine Inspection (OCMI). If the annual hull assessment reveals significant damage or corrosion, where temporary repairs have been made, or where other critical areas of concern have been identified, the OCMI may require an expanded examination to include an underwater hull examination using divers. If an underwater examination is required, the examination must focus on areas at higher risk of damage or corrosion and must include a representative sampling of hull gaugings.
(b) If an underwater survey is required for the annual hull condition assessment, the OCMI may require the presence of a third party examiner and a written hull examination report must be submitted to the OCMI.

(a) A vessel carrying more than 600 passengers or with overnight accommodations for more than 49 passengers must meet the requirements for stairways, ladders, and elevators in § 72.05-20 of this chapter.
(b) Materials. (1) Stairways, stairtowers, ladders, elevators, and landings must be designed with sufficient strength to sustain a load of 4.8 kPa (100 pounds per square foot) with a safety factor of 4, based on ultimate strength of the material;
(2) All stairways, ladders, elevators, and landings within machinery spaces and cargo holds must be composed of steel; and
(3) All stringers, treads, and all platforms and landings of all stairways shall be composed of steel, and risers must be of approved incombustible material, except that:
(i) Stairways, ladders, elevators, stringers, treads, platforms, and landings protected from potential fire exposure by being in either exterior locations or within protective enclosure bulkheads, decks and doors as described in the requirements of paragraph (j), may be constructed of approved incombustible material; and
(ii) All stairways, ladders, elevators, stringers, treads, platforms, and landings subject to potential fire exposure and not within a protective enclosure must be composed of steel unless their failure will not hinder fire fighter access or debarkation.
(c) A stairway or stairtower must be fitted with handrails on both sides at a vertical height above the tread at its nosing of between 840 and 910 millimeters (33 and 36 inches). A stairway or stairtower of more than 1,680 millimeters (66 inches) in width must also be fitted with a center handrail.
(d) A handrail fitted in a stairtower, stairway, landing, ladder, or elevator must be constructed of noncombustible material.
(e) A stairway or stairtower must be clear of all obstructions other than handrails.
(f) Curved, spiral, or winding stairways are permitted only with the specific approval of the Commandant.
(g) Differences in the depth of tread or height of riser of stairs in different flights of stairs in a stairway or stairtower must be minimized. In an individual flight of stairs in a stairway or stairtower, the depth of the tread and the height of riser shall not have a variance exceeding 5 millimeters (0.19685 inches).
(h) In a stairway or stairtower, the sum of the riser height and tread depth must be at least 432 millimeters (17 inches) and not more than 455 millimeters (18 inches). A stairway or stairtower having treads less than 254 millimeters (10 inches) in depth must have a nosing of 12.7 millimeters (0.5 inches) in width.
(i) Landings for stairways and stairtowers must meet the following requirements:
(1) A clear landing having an area at least equal to the square of the tread width must be provided at the top and bottom of each stairway; and
(2) Any interruption or change of direction in a stairway must be accomplished by means of an intermediate landing of a width and length at least equal to the tread width of the stairway.
(j) A stairway or stairtower must not have an angle of inclination from the horizontal of more than 40 degrees. However, stairways accessing spaces visited solely by crew members must not have an angle of inclination from the horizontal of more than 50 degrees. The Commanding Officer, Marine Safety Center may approve higher angles of inclination for spaces with severe space constraints.
(k) Where a continuous vertical deck penetration for a stairway or elevator exceeds one deck, the integrity of all decks must be assured by enclosure bulkheads and decks meeting the requirements of §§ 116.415(b) and 116.415(c) of this part. Doors meeting the requirements of §§ 116.435(b) and 116.435(c) of this part must be fitted in the enclosure at each deck serviced.
(l) Where a vertical deck penetration for a stairway or elevator involves only one deck, the integrity of the deck must be assured as required by paragraph (k) of this section. Alternatively the integrity of the deck may be maintained at one level only by means of bulkheads of the same fire control boundary rating as the deck penetrated. A door meeting the requirements of §§ 116.435(b) and 116.435(c) of this part must be fitted in the enclosure. In spaces containing a balcony, the integrity of the balcony deck in the way of stairways or elevators need not be assured. However, such stairways must not be considered to be a means of escape.
(m) Arrangements. (1) Each main vertical zone with more than two deck levels, each having enclosed or partially enclosed accommodation spaces, other than washroom or toilet spaces and open decks, must be served by at least one stairtower, so that a person may escape from any accommodation space or any other space where persons may be normally quartered or employed, to all other decks having any such spaces within the same main vertical zone, without coming out of the stairtower enclosure. Where a stairtower is accessible from two main vertical zones, it may be considered as the required stairtower for both main vertical zones provided all boundaries of the stairtower meet main vertical zone boundary requirements contained in § 116.415 of this part.
(2) Each stairtower must give access to an embarkation station or an area of refuge identified in the emergency escape plan required by § 116.520.
(3) Stairtowers must not give direct access to overnight accommodations or spaces of type 9, 10, 11, or 12.
(4) A stairtower is not required to extend below deck to serve spaces in which a fire is likely to originate if one of the means of escape is:
(i) A stairway that leads directly to a weather deck; or
(ii) A stairway leading to a stairtower enclosure that includes self closing fire doors at both the top and bottom; or
(iii) An alternative stairtower arrangement providing an equivalent level of safety is acceptable to the Commanding Officer, Marine Safety Center.
(5) The Commanding Officer, Marine Safety Center may accept other means of escape in combination with a stairtower provided the exits open directly to weather or through a main vertical zone bulkhead.
(6) For vessels in which a stairtower is not required, a stairway must provide a means of escape for each deck of the main vertical zone.
(n) The minimum tread width of a stairway or stairtower must be 8.4 millimeters (0.333 inches) for each person served, but must not be less than 910 millimeters (36 inches). However, in stairways accessing spaces utilized solely by crew members, the minimum tread width must be 8.4 millimeters (0.333 inches) for each person served, but not less than 710 millimeters (28 inches).
(1) The minimum tread width of a stairway or stairtower must be determined for each deck considering only those persons on that deck, except as provided in paragraph (n)(3) of this section. Once a minimum tread width has been established at any deck, it must not be decreased in the direction of escape.
(2) In determining the number of persons served, a space must be considered to contain at least the number of persons as follows:
(i) Passenger overnight accommodation spaces: Designed capacity;
(ii) Accommodation spaces having fixed seating for passengers: Maximum seating capacity;
(iii) Public spaces, including spaces such as casinos, restaurants, club rooms, and cinemas, and public accommodation spaces as defined in § 114.400 of this subchapter, except overnight accommodation spaces: One person for each 0.9 square meters (10 square feet) of deck area. In computing such deck area, the following areas must be excluded:
(A) Areas for which the number of persons permitted is determined using the fixed seating criterion;
(B) Obstructions, including stairway and elevator enclosures, elevated stages, bars, and cashier stands, but not including slot machines, tables, or other room furnishings;
(C) Toilets and washrooms;
(D) Interior passageways less than 850 millimeters (34 inches) wide and passageways on open deck less than 710 millimeters (28 inches) wide;
(E) Spaces necessary for handling lifesaving equipment, anchor handling equipment, or line handling gear, or in way of sail booms or running rigging; and
(F) Bow pulpits, swimming platforms, and areas that do not have a solid deck, such as netting on multi hull vessels;
(iv) Crew overnight accommodation spaces: Two-thirds designed capacity; and
(v) Work spaces: Occupancy under normal operating conditions.
(3) If a stairway forms part of a normal embarkation or debarkation route, or egress route to an area of refuge, the number of persons using the stairway for that purpose must be used in determining the minimum tread width. The Commanding Officer, Marine Safety Center, may approve a narrower stairway width if a narrower stairway will not unreasonably impede the flow of persons out of the space requiring egress or from an area of refuge to an embarkation station. Specific consideration can be given by the Marine Safety Center to the arrangement of landing area in excess of that required by paragraph (i) of this section when considering the approval of a narrower stairway width. However, the stairway width must be at least 910 millimeters (36 inches) unless the stairway is utilized solely by crew members, in which case the minimum tread width must be at least 710 millimeters (28 inches).
(4) If more than one stairtower serves a main vertical zone, the number of persons in that main vertical zone may be distributed among the stairtowers.

§ 136.120 Special consideration.
Based on a review of relevant information and on the TSMS applicable to the vessel, the cognizant OCMI who issues the COI may give special consideration to authorizing departures from specific requirements, when unusual circumstances or arrangements warrant such departures and when an equivalent level of safety is provided.
§ 136.130 Options for documenting compliance to obtain a Certificate of Inspection.
(a) There are two options for documenting compliance with the requirements in this subchapter to obtain a COI:
(1) The Coast Guard option, in which all inspections of the towing vessel are conducted by the Coast Guard, as discussed in § 136.210 and parts 137 and 140 through 144 of this subchapter; or
(2) The TSMS option, as discussed in § 136.210, and in parts 137 through 144 of this subchapter.
(b) Regardless of the option chosen, the Coast Guard is responsible for issuing a towing vessel COI, and may board a vessel at any time to verify compliance and take appropriate action.
(c) An owner or managing operator choosing the Coast Guard option may use a management system, vessel operations manual, towing vessel record (TVR), or logbook to meet this subchapter’s recordkeeping requirements.
(d) When submitting an application for inspection, the owner or managing operator must specify on the application which option he or she chooses for each particular towing vessel. Owners or managing operators may choose different options for the individual vessels within their fleets.
(e) Requests to change options during the period of validity of an existing COI must be accompanied by an application to the OCMI for a new COI. If the requirements for the new option are met, the OCMI will issue the vessel a new COI.
§ 136.172 Temporary compliance for existing towing vessels.
An existing towing vessel subject to this subchapter will remain subject to Coast Guard regulations applicable to the vessel on July 19, 2016 until either July 20, 2018 or the date the vessel obtains a COI, whichever date is earlier.
§ 136.175 Approved equipment.

(2) Objective evidence that the vessel’s structure, stability, and essential systems comply with the applicable requirements of this subchapter for the intended route and service. This objective evidence may be in the form of a survey report issued by a TPO or another form acceptable to the Coast Guard.
§ 136.212 Inspection for certification.
(a) Frequency of inspections. After a towing vessel receives its initial COI, the OCMI will inspect a towing vessel subject to this subchapter located in his or her jurisdiction at least once every 5 years. The OCMI must ensure that every towing vessel is of a structure suitable for its intended route. If the OCMI deems it necessary, he or she may direct the vessel to get underway, and may adopt any other suitable means to test the towing vessel and its equipment.
(b) Nature of inspection. The inspection will ensure that the vessel is in satisfactory condition and fit for the service for which it is intended, and that it complies with the applicable statutes and regulations for such vessels. The inspection will include inspections of the structure, pressure vessels and their appurtenances, piping, main and auxiliary machinery, electrical installations, lifesaving appliances, fire detecting and extinguishing equipment, pilot boarding equipment, and other equipment. The inspection will also determine that the vessel is in possession of any valid certificates or licenses issued by the Federal Communications Commission, if required. The inspection will also include an examination of the vessel’s lights, means of making sound signals and distress signals, and pollution prevention systems and procedures.
(c) Time of issuance of COI. The OCMI will issue a vessel a new COI after the vessel successfully completes the inspection for certification.
§ 136.215 Period of validity.
(a) A COI for a towing vessel is valid for 5 years from the date of issue.
(b) For a towing vessel utilizing the TSMS option, the COI is invalid upon the expiration or revocation of the owner or managing operator TSMS certificate or the ISM Code Certificate.
(c) A COI may be suspended and withdrawn or revoked by the cognizant Officer in Charge, Marine Inspection at any time for noncompliance with the requirements of this subchapter.
§ 136.220 Posting.
(a) The original COI must be framed under glass or other transparent material and posted in a conspicuous place onboard the towing vessel.
(b) If posting is impracticable, the COI must be kept on board in a weathertight container and must be readily available.
§ 136.230 Routes permitted.
(a) The area of operation for each towing vessel and any necessary operational limits are determined by the cognizant OCMI and recorded on the vessel’s COI. Each area of operation, referred to as a route, is described on the COI under the major headings “Oceans,” “Coastwise,” “Limited Coastwise,” “Great Lakes,” “Lakes, Bays, and Sounds,” or “Rivers,” as applicable. Additional limitations imposed or extensions granted are described by reference to bodies of waters, geographical points, distances from geographical points, distances from land, depths of channel, seasonal limitations, and similar factors.
(b) Operation of a towing vessel on a route of lesser severity than those specifically described or designated on the COI is permitted, unless the route is expressly prohibited on the COI. The general order of decreasing severity of routes is: Oceans; coastwise; limited coastwise; Great Lakes; lakes, bays, and sounds; and rivers. The cognizant OCMI may prohibit a vessel from operating on a route of lesser severity than the primary route on which a vessel is authorized to operate, if local conditions necessitate such a restriction.
(c) When designating a permitted route or imposing any operational limits on a towing vessel, the cognizant OCMI may consider:
(1) The route-specific requirements of this subchapter;
(2) The performance capabilities of the vessel based on design, scantlings, stability, subdivision, propulsion, speed, operating modes, maneuverability, and other characteristics;
(3) The suitability of the vessel for nighttime operations and use in all weather conditions;
(4) Vessel operations in globally remote areas or severe environments not covered by this subchapter. Such areas may include, but are not limited to, polar regions, remote islands, areas of extreme weather, or other remote areas where timely emergency assistance cannot be anticipated; and
(5) The TSMS applicable to the vessel, if the vessel has one.
§ 136.235 Certificate of Inspection amendment.
(a) An amended COI may be issued at any time by the cognizant OCMI. The amended COI replaces the original, but the expiration date remains the same as that of the original. An amended COI may be issued to authorize and record a change in the dimensions, gross tonnage, owner, managing operator, manning, persons permitted, route permitted, conditions of operations, or equipment of a towing vessel, from that specified in the current COI.
(b) The owner or managing operator of the towing vessel must make a request for an amended COI to the cognizant OCMI any time there is a change in the character of the vessel or in its route, equipment, ownership, operation, or similar factors specified in its current COI. The OCMI may need to conduct an inspection before issuing an amended COI.
(c) For those vessels selecting the TSMS option, the owner or managing operator of the towing vessel must provide to the OCMI objective evidence of compliance with the requirements in this subchapter prior to the issuance of an amended COI. The evidence must:
(1) Be from a TPO and prepared in accordance with parts 138 and 139 of this subchapter; and
(2) Consider the change in the character of a vessel or in its route, equipment, ownership, operation, or similar factors specified in the vessel’s current COI.
§ 136.240 Permit to proceed.
Permission to proceed to another port for repairs (Form CG-948) may be required for a towing vessel that is no longer in compliance with its COI. This permission may be necessary in certain situations, including damage to the vessel, failure of an essential system, or failure to comply with a regulation, including failure to comply with the TSMS requirements, if appropriate.
(a) What a vessel with a TSMS must do before proceeding to another port for repairs. A vessel with a TSMS may proceed to another port for repair, if:
(1) In the judgment of the owner, managing operator, or master, the trip can be completed safely;
(2) The TSMS addresses the condition of the vessel that has resulted in non-compliance and the necessary conditions under which the vessel may safely proceed to another port for repair;
(3) The vessel proceeds as provided in the TSMS and does not tow while proceeding, unless the owner or managing operator determines that it is safe to do so; and
(4) The owner or managing operator notifies the cognizant OCMI in whose zone the non-compliance occurred or is discovered, before the vessel proceeds. The owner or operator must also notify the cognizant OCMI in any other OCMI zones through which the vessel will transit.
(b) What another vessel must do before proceeding to another port for repairs. If a vessel does not have a TSMS, or a vessel has one but it does not address the condition of the vessel that has resulted in non-compliance or the necessary conditions under which the vessel may safely proceed to another port for repair, the owner, managing operator, or master must request permission to proceed from the cognizant OCMI in whose zone the non-compliance occurs or is discovered. This permission operates as follows:
(1) The request for permission to proceed may be made electronically, in writing, or orally. The cognizant OCMI may require a written description, a damage survey, or other documentation to assist in determining the nature and seriousness of the non-compliance.
(2) The vessel will not engage in towing, unless the cognizant OCMI determines it is safe to do so.
(3) The Coast Guard may issue the permit either on Form CG-948, “Permit to Proceed to Another Port for Repairs,” or in letter form, and will state the conditions under which the vessel may proceed to another port for repair.
(c) Inspection or examination. The cognizant OCMI may require an inspection of the vessel by a Coast Guard Marine Inspector or an examination by a surveyor from a TPO prior to the vessel proceeding.
§ 136.245 Permit to carry an excursion party or temporary extension or alteration of route.
(a) A towing vessel must obtain approval to engage in an excursion prior to carrying a greater number of persons than permitted by the COI, or to temporarily extend or alter its area of operation.
(b) For a vessel utilizing the TSMS option, the vessel may engage in an excursion, if:
(1) In the opinion of the owner, managing operator, or master the operation can be undertaken safely;
(2) The TSMS addresses the temporary excursion operation contemplated; the necessary conditions under which the vessel may safely conduct the operation, including the number of persons the vessel may carry; the crew required; and any additional lifesaving or safety equipment required;
(3) The vessel proceeds as provided in the TSMS; and
(4) The owner, managing operator, or master notifies the cognizant OCMI at least 48 hours prior to the temporary excursion operation. The cognizant OCMI may require submission of pertinent provisions of the TSMS applicable to the vessel for review and onboard verification of compliance. If the cognizant OCMI has reasonable cause to believe that the TSMS applicable to the vessel is insufficient for the intended excursion, additional information may be requested and/or additional requirements may be imposed.
(c) If the towing vessel is not under a TSMS, or the TSMS applicable to the vessel does not address the temporary excursion operation:
(1) The owner or managing operator must submit an application to the cognizant OCMI. The application must state the intended route, number of passengers or guests, and any other conditions applicable to the excursion that exceed those specified in its COI.
(2) The cognizant OCMI may issue the permit either on Form CG-949, “Permit To Carry Excursion Party,” or in letter form. The cognizant OCMI will indicate on the permit the conditions under which it is issued, the number of persons the vessel may carry, the crew required, any additional lifesaving or safety equipment required, the route for which the permit is granted, and the dates on which the permit is valid. The application may be made electronically, in writing, or orally.
(3) The vessel may not engage in towing during the excursion, unless the cognizant OCMI determines it is safe to do so.
(d) The cognizant OCMI may require an inspection of the vessel by a Coast Guard Marine Inspector or an examination by a surveyor from a TPO prior to the vessel proceeding.

PART 137 – VESSEL COMPLIANCE
Subpart A – General
§ 137.100 Purpose.
This part describes the procedures owners or managing operators of towing vessels must use to demonstrate compliance with the requirements of this subchapter.
§ 137.120 Responsibility for compliance.
(a) The owner and managing operator must ensure that the towing vessel is in compliance with this subchapter and other applicable laws and regulations at all times.
(b) Non-conformities and deficiencies must be corrected in a timely manner.
§ 137.130 Program for vessel compliance for the Towing Safety Management System (TSMS) option.
The owner or managing operator of a towing vessel choosing to use the TSMS option must implement an external or internal survey program for vessel compliance. The program for vessel compliance can be either:
(a) An external survey program, in which the owner or managing operator would have a third-party organization (TPO) conduct either the surveys required by § 137.205, the examinations required by § 137.310, or both; or
(b) An internal survey program, in which the owner or managing operator would conduct either the surveys required by § 137.210, the examinations required by § 137.315, or both, using internal resources or contracted surveyors. The internal survey program would be conducted with the oversight of a TPO.
(c) Each program of either type must include:
(1) Owner or managing operator policy regarding the surveying and examination of towing vessels;
(2) Procedures for conducting towing vessel surveys and examinations, as described in this part;
(3) Procedures for reporting and correcting non-conformities and deficiencies;
(4) Identification of the individual or individuals responsible for the management of the program, and their qualifications; and
(5) Documentation of compliance activities.
§ 137.135 Reports and documentation required for the TSMS option.
(a) The TSMS option requires a report detailing each internal survey of a towing vessel. Each report must include:
(1) Vessel name;
(2) Other vessel identifier, such as an official number or State number;
(3) Name and business address of owner or managing operator;
(4) Date and location of the survey;
(5) Date the report of the survey was issued, if different than the date the survey was concluded;
(6) Name of the surveyors;
(7) Name and business address of the TPO the surveyors represent, if applicable;
(8) Signatures of surveyors;
(9) A descriptive list of the items examined or witnessed during each survey;
(10) A descriptive list of all non-conformities identified during each survey, including those that were corrected during the course of the survey;
(11) A descriptive list of:
(i) All non-conformities remaining at the end of each survey;
(ii) The required corrective actions;
(iii) The latest date of required corrective action; and
(iv) A description of the means by which the corrective actions were verified;
(12) A descriptive list of items that need to be repaired or replaced before the vessel continues service; and
(13) A statement that the vessel complies with the applicable requirements of this subchapter and is fit for its route and service, subject to the correction of non-conformities.
(b) The owner or managing operator must provide objective evidence of compliance with this part in accordance with the TSMS applicable to the vessel.
Subpart B – Inspections and Surveys for Certification
§ 137.200 Documenting compliance for the Coast Guard inspection option.
A towing vessel subject to this subchapter and choosing the Coast Guard inspection option, or required to have the Coast Guard inspection option, must undergo an annual inspection within 3 months before or after the COI anniversary date.
(a) Owners and managing operators must contact the cognizant Officer in Charge, Marine Inspection (OCMI) to schedule an inspection at a time and place the OCMI approves. No written application is required.
(b) Annual inspections will be similar to the inspection for certification but will cover less detail unless the marine inspector finds deficiencies or determines that a major change has occurred since the last inspection. If the marine inspector finds deficiencies or finds that a major change to the vessel has occurred, he or she will conduct a more detailed inspection to ensure that the vessel is in satisfactory condition and fit for the service for which it is intended. If the vessel passes the annual inspection, the Coast Guard will endorse the vessel’s current Certificate of Inspection (COI).
(c) If the annual inspection reveals the need, the owner or managing operator must make any or all repairs or improvements within the time period specified by the OCMI. The OCMI may use Form CG-835, “Notice of Merchant Marine Inspection Requirements,” to record deficiencies discovered during the inspection. The OCMI will then give a copy of the completed form to the master of the vessel.
(d) Nothing in this subpart limits the marine inspector from conducting any tests or inspections he or she deems necessary to be assured of the vessel’s seaworthiness or fitness for its route and service.
§ 137.202 Documenting compliance for the TSMS option.
The owner or managing operator of a towing vessel that chooses the TSMS option for a towing vessel must document compliance with this subpart as follows:
(a) Prior to obtaining the vessel’s initial COI, the owner or managing operator must provide a report to the Coast Guard of a survey as described in § 137.215 that demonstrates that the vessel complies the requirements of this part.
(b) For the re-issuance of the vessel’s COI, the owner or managing operator must:
(1) Provide objective evidence of an external survey program as described in § 137.205; or
(2) Provide objective evidence of an internal survey program as described in § 137.210.
§ 137.205 External survey program.
(a) The owner or managing operator of a towing vessel that has selected the TSMS option and who has chosen to demonstrate compliance through an external survey program must:
(1) Have the vessel surveyed annually by a surveyor from a TPO;
(2) Ensure the survey is conducted in accordance with § 137.215;
(3) Ensure the survey is conducted within 3 months of the anniversary date of the COI;
(4) Ensure the TSMS applicable to the vessel includes policies and procedures for complying with this section; and
(5) Make the applicable sections of the TSMS available to the surveyor.
(b) The TPO must issue a report that meets the requirements in § 137.135.
§ 137.210 Internal survey program.
(a) The owner or managing operator of a towing vessel that has selected the TSMS option and who has chosen to demonstrate vessel compliance through an internal survey program must ensure that the TSMS applicable to the vessel includes:
(1) Procedures for surveying and testing described in § 137.215;
(2) Equipment, systems, and onboard procedures to be surveyed;
(3) Identification of items that would need repair or replacement before the vessel could continue in service, such as deficiencies identified on Form CG-835, “Notice of Merchant Marine Inspection Requirements,” noted survey deficiencies, non-conformities, or other corrective action reports;
(4) Procedures for documenting and reporting non-conformities and deficiencies;
(5) Procedures for reporting and correcting major non-conformities;
(6) The responsible person or persons in management who have the authority to:
(i) Stop all vessel operations pending the correction of non-conformities and deficiencies;
(ii) Oversee vessel compliance activities; and
(iii) Track and verify that non-conformities and deficiencies were corrected;
(7) Procedures for recordkeeping; and
(8) Procedures for assigning personnel with requisite experience and expertise to carry out the elements of the survey.
(b) The owner or managing operator is not required to survey the items as described in § 137.220 as one event, but may survey items on a schedule over time, provided that the interval between successive surveys of any item does not exceed 1 year, unless otherwise prescribed.
§ 137.212 Coast Guard oversight of vessel survey program for vessels under the TSMS option.
If the cognizant OCMI has reasonable cause to believe that a vessel’s survey program is deficient, that OCMI may:
(a) Require an audit or survey of the vessel in the presence of a representative of the cognizant OCMI;
(b) Increase the frequency of the audits;
(c) For vessels under the internal survey program, require that the vessel comply with the external survey program requirements of § 137.205;
(d) Require any other specific action within his or her authority that he or she considers appropriate; or
(e) For repeatedly deficient surveys, remove the vessel and or owner or managing operator from using the TSMS option.
§ 137.215 General conduct of survey.
(a) When conducting a survey of a towing vessel as required by this subpart, the surveyor must determine that the item or system functions as designed, is free of defects or modifications that reduce its effectiveness, is suitable for the service intended, and functions safely in a manner consistent for vessel type, service and route.
(b) The survey must address the items in § 137.220 as applicable, and must include:
(1) A review of certificates and documentation held on the vessel;
(2) A visual examination and tests of the vessel and its equipment and systems in order to confirm that their condition is properly maintained and that proper quantities are onboard;
(3) A visual examination of the systems used in support of drills or training to determine that the equipment utilized during a drill operates as intended; and
(4) A visual examination to confirm that unapproved modifications were not made to the vessel or its equipment.
(c) Beyond the minimum standards required by this section, the thoroughness and stringency of the survey will depend upon the condition of the vessel and its equipment.
