Requirements
§ 32.02–1 Means of escape—T/ALL.
On all tankships where the plans and
arrangements will possibly permit, all
passageways leading to living quarters,
or places where anyone may be regularly employed, shall be provided with
not less than two avenues of escape so
located that if one of such avenues is
not available another may be. The locality and arrangement of such additional means of escape shall be determined by the inspectors as will in their
judgment best carry out the purpose
for which this provision was made.

between
both ends of the vessel, such as a raised
fore and aft bridge or side tunnels,
must be provided. Previously approved
arrangements may be retained so long
as they are maintained in satisfactory
condition to the satisfaction of the Officer in Charge, Marine Inspection.
[CGD 95–027, 61 FR 25997, May 23, 1996]
§ 32.02–10 Rails—TB/ALL.
(a) All tank vessels, except unmanned tank barges, contracted for on
or after July 1, 1969, shall have efficient guard rails or bulwarks on decks
and bridges. The height of rails or bulwarks shall be at least 391⁄2 inches from
the deck except that where this height
would interfere with the normal operation of the vessel, a lesser height may
be approved by the Commandant. At
exposed peripheries of the freeboard
and superstructure decks the rails
shall be in at least three courses including the top. The opening below the
lowest course shall not be more than 9
inches. The courses shall not be more
than 15 inches apart. In the case of
ships with rounded gunwales, the guard
rail supports shall be placed on the flat
of the deck. On other decks and bridges
the rails shall be in at least two
courses, including the top, approximately evenly spaced. All rails shall
consist of solid or tubular sections or
chains or wire rope or a combination
thereof.
(b) Where it can be shown to the satisfaction of the Commandant that a
vessel is engaged exclusively on voyages of a sheltered nature, the provisions of paragraph (a) of this section
may be relaxed.
(c) Tank vessels contracted for prior
to July 1, 1969, except unmanned tank
barges, assigned a deeper load line
under part 42 of subchapter E (Load
Lines) of this chapter shall have efficient guard rails or bulwarks as required by paragraph (a) of this section.
Otherwise, existing rails and bulwarks
previously approved approved will be
considered satisfactory so long as they
are maintained in good condition.
Minor repairs and alterations may be
made to the same standards as the
original construction.
(d) All tank vessels in ocean and
coastwise service, except unmanned
tank barges, constructed on or after
June 15, 1987, must have suitable storm
rails installed in all passageways and
at the deckhouse sides on weather
decks where persons on board might
have normal access. Storm rails must
be installed on both sides of passageways which are six feet or more in
width. Tank vessels to which this paragraph applies constructed prior to June
15, 1987, may retain previously accepted
or approved installations so long as
they are maintained in good condition

the bottom of the keel forward or aft,
as the case may be, to the location of
the draft marks.
(d) In cases where a vessel may have
a skeg or other appendage extending
locally below the line of the keel, the
draft at the end of the vessel adjacent
to such appendage shall be measured to
a line tangent to the lowest part of
such appendage and parallel to the line
of the bottom of the keel.
(e) Draft marks must be separated so
that the projections of the marks onto
a vertical plane are of uniform height
Name of tankship—T/ALL.
Every tankship shall have the name

Subpart 32.63—Hull and Cargo
Tank Requirements for Tank
Barges Constructed or Converted On or After July 1,
1964, and Carrying Certain
Dangerous Bulk Cargoes
§ 32.63–1
Application—B/ALL.
(a) The requirements of this subpart
shall apply to all tank barges, the construction or conversion of which is
started on or after July 1, 1964, and carrying those cargoes listed in Table
30.25–1 which are defined as:
(1) Flammable liquids having a Reid
vapor pressure in excess of 25 pounds
per square inch, absolute, in independent tanks (part 32).
(2) Liquefied flammable gases (part 38
of this subchapter).
[CGFR 70–10, 35 FR 3709, Feb. 25, 1970]
§ 32.63–5 Barge hull classifications—B/
ALL.
(a) Each barge subject to the provision of this subpart shall be assigned a
hull type number. The Commandant
will designate the barge hull types to
be used for carrying cargoes in order to
insure that the vessel is designed consistent with the degree and nature of
the hazard of the commodity carried.
(b) For this purpose the barge hull
types shall be as follows:
(1) Type I barge hull. Barge hulls
classed as Type I are those designed to
carry products which require the maximum preventive measures to preclude
the uncontrolled release of the cargo to
the waterways and/or atmosphere.
(2) Type II barge hull. Barge hulls
classed as Type II are those designed to
carry products which require substantial preventive measures to preclude
uncontrolled release to the atmosphere, but whose uncontrolled release
to the waterways does not constitute a
longlasting public or operating personnel hazard, though local and temporary pollution may occur.
(3) Type III barge hull. Barge hulls
classed as Type III are those designed
to carry products of sufficient hazard
to require a moderate degree of control.
§ 32.63–8 Alternative arrangements—B/
ALL.
(a) Alternative arrangements, differing from those specifically required
by this subpart, may be considered and
approved by the Commandant, if it is
demonstrated to his satisfaction that a
degree of safety is obtained which is
consistent with the intent of this subpart.
§ 32.63–10 Rakes
and
coamings—B/
ALL.
(a) Each barge hull shall be constructed with a suitable blow form
(length, shape, and height of headlog)
to protect against diving at the maximum speed at which the barge is designed to be towed. In any integrated
tow, only the lead barge need comply
with this requirement. In any case, the
operator of the towing vessel shall be
guided by appropriate speed limitations.
(b) All open hopper type barge hulls
shall be provided with coamings around
the hopper space and, additionally, a
36-inch minimum height plowshare
breakwater on the forward rake.
Coamings shall have a minimum
height of 36 inches forward graduated
to a minimum height of 24 inches at
midlength and 18 inches thereafter.
§ 32.63–20 Hull structure—B/ALL.
(a) General. In addition to complying
with the requirements of § 32.60–1, as

Coast Guard, DHS
§ 32.65–1
applicable, barge hulls of Types I and II
shall comply with the provisions of
this section.
(b) Types I and II barge hull. Under an
assumed grounding condition such that
the forward rake bulkhead rests upon a
pinnacle at the water surface, the maximum hull bending stress shall not exceed the following limits:
(1) Independent tanks may be installed in such a manner that they do
not contribute to the strength and
stiffness of the barge. In such case, the
hull stress shall not exceed either 50
percent of the minimum ultimate tensile strength of the material or 70 percent of the yield strength when specified, whichever is greater.
(2) The Commandant may consider a
reduction in hull stress when independent tanks are installed in such a
manner as to contribute to the
strength and stiffness of the barge and
this is accounted for in determining
the effective section modulus of the
barge. In such case, the hull stress
shall not exceed the percentage stress
values prescribed in paragraph (b)(1) of
this section multiplied by the quantity
(1.5¥SWT/UTS), where SWT is the
stress calculated without including the
effect of the tanks, and UTS is the
minimum ultimate tensile strength of
the material. The value SWT, however,
shall in no case be more than 75 percent of UTS.
§ 32.63–25 Cargo tanks and supports—
B/ALL.
(a) General. Saddles and hold-down
securing straps for independent cargo
tanks shall be designed to prevent tank
failure due to loads induced in the saddles or straps by barge deflection.
(b) Collision protection. (1) All independent cargo tanks installed on Type
I and Type II barge hulls shall be protected with suitable collision chocks or
collision straps to withstand a longitudinal collision load of one and one-half
times the weight of the tank and cargo.
All other independent cargo tanks
shall be provided with suitable collision chocks or collision straps to withstand a longitudinal collision load
equal to the weight of the tank and
cargo.
(2) All cargo tanks shall be so located
as to reduce the likelihood of their
being damaged in the event of collision. This protection shall be obtained
by locating the cargo tanks not less
than 4 feet from the side shell and boxend for Type I hulls and 3 feet for Type
II barge hulls, and not less than 25 feet
from the headlog at the bow for both
types.
(c) Cargo tank design—(1) Types I and
II barge hulls. (i) In addition to requirements provided for in applicable regulations for a specific commodity, cargoes subject to the provisions of this
subpart shall be transported in cargo
tanks meeting the requirements of this
paragraph. Pressure vessel-type cargo
tanks shall have sufficient additional
strength so as to limit the maximum
combined tank stress, including saddle
horn and bending stresses, to 1.5 times
the maximum allowable hoop stress in
still water, and to the yield strength of
the tank material or 70 percent of the
minimum ultimate tensile strength of
the tank material, if less, in the
grounded condition as required by
§ 32.63–20(b).
(ii) Gravity type cargo tanks shall
have sufficient additional strength to
limit the maximum combined tank
stress, including saddle horn and bending stresses, to the yield strength of
the tank material or 70 percent of the
minimum ultimate tensile strength of
the tank material, if less, in the
grounded condition as required by
§ 32.63–20(b).
(2) Type III barge hulls. In addition to
the requirements of this paragraph,
pressure vessel-type cargo tanks shall
have sufficient additional strength so
as to limit the maximum combined
stress, including saddle horn and bending stresses, to 1.5 times the maximum
allowable hoop stress.

under 65 feet shall be equipped with 1 B-V extinguisher.
(Refer to Table 34.50–5(c).)
2 Vessels of 1,000 gross tons and over on an international
voyage shall have at least 2 fire pumps.
3 From hydrants having greatest pressure drop between
fire-pump(s) and nozzles.
4 Where 21⁄2-inch hydrant size is required, two 11⁄2-inch outlets may be substituted therefor with two 11⁄2-inch hoses.
(b) Each pump shall be capable of delivering simultaneously the number of
streams of water required by table
34.10–5(a) from the outlets having the
greatest pressure drop between fire
pump(s) and nozzles at a Pitot tube
pressure of approximately 75 p.s.i.
Where 11⁄2-inch hose is permitted in lieu
of 21⁄2-inch hose by footnote 3 of Table
34.10–5(a), the pump capacity shall be
determined on the basis that both
hoses are used.
(c) On tankships of 1,000 gross tons
and over on an international voyage,
each required fire pump, while delivering water through the fire main system at a pressure corresponding to
that required by § 34.10–15(e), shall have

no case shall a pump having connection
to an oil line be used as a fire pump.
Branch lines connected to the fire main
for purposes other than fire and deck
wash shall be arranged so that the requirements of paragraph (b) of this section and any other services installed on
the fire main can be met simultaneously.
(g) On all vessels where two fire
pumps are required, they shall be located in separate spaces, and the arrangement of pumps, sea connections,
and sources of power shall be such as to
insure that a fire in any one space will
not put all of the fire pumps out of operation. However, where it is shown to
the satisfaction of the Commandant
that it is unreasonable or impracticable to meet this requirement due to
the size, or arrangement of the vessel,
or for other reasons, the installation of
a total flooding carbon dioxide system
may be accepted as an alternate method of extinguishing any fire which
would affect the powering and operation of at least one of the required fire
pumps.

§ 34.15–5
46 CFR Ch. I (10–1–05 Edition)
(b) Total available supply. (1) A separate supply of carbon dioxide need not
be provided for each space protected.
The total available supply shall be at
least sufficient for the space requiring
the greatest amount.
(c) Dry cargo spaces. (1) The number
of pounds of carbon dioxide required for
each space shall be equal to the gross
volume of the space in cubic feet divided by 30.
(2) Although separate piping shall be
led to each cargo hold and ’tween deck,
for the purpose of determining the
amount of carbon dioxide required, a
cargo compartment will be considered
as the space between watertight or
firescreen bulkheads and from the tank
top or lowest deck to the deck head of
the uppermost space on which cargo
may be carried. If a trunk extends beyond such deck, the trunk volume shall
be included. Tonnage openings shall be
considered as sealed for this purpose.
(3) Branch lines to the various cargo
holds and ’tween decks shall not be less
than 3⁄4-inch standard pipe size.
(4) No specific discharge rate need be
applied to such systems.
(d) Machinery spaces, pumprooms,
paint lockers, and similar spaces. (1) Except as provided in paragraph (d)(4) of
this section, the number of pounds of
carbon dioxide required for each space
shall be equal to the gross volume of
the space divided by the appropriate
factor noted in Table 34.15–5(d)(1). If
fuel can drain from the compartment
being protected to an adjacent compartment, or if the compartments are
not entirely separate, the requirements
for both compartments shall be used to
determine the amount of carbon dioxide to be provided. The carbon dioxide
shall be arranged to discharge into
both such compartments simultaneously.
(2) For the purpose of the above requirement of this paragraph, the volume of a machinery space shall be
taken as exclusive of the normal machinery casing unless the boiler, internal combustion propelling machinery,
or fuel oil installations subject to the
discharge pressure of the fuel oil service pump extend into such space, in
which case the volume shall be taken
to the top of the casing or the next material reduction in casing area, whichever is lower. The terms ‘‘normal machinery casing’’ and ‘‘material reduction in casing area’’ shall be defined as
follows:
(i) By ‘‘normal machinery casing’’
shall be meant a casing the area of
which is not more than 40 percent of
the maximum area of the machinery
space.
(ii) By ‘‘material reduction in casing
area’’ shall be meant a reduction to at
least 40 percent of the casing area.
(3) For the purpose of the above requirements of this paragraph, the volume of a pumproom shall include the
pumproom and all associated trunks up
to the deck at which access from the
weather is provided.
(4) For tankships on an international
voyage contracted for on or after May
26, 1965, the amount of carbon dioxide
required for a space containing propulsion boilers or internal combustion
propulsion machinery shall be as given
by paragraphs (d) (1) and (2) of this section or by dividing the entire volume,
including the casing, by a factor of 25,
whichever is the larger.
(5) Branch lines in the various spaces
shall be noted in Table 34.15–5(d)(5).

controls shall be located in a box or
other enclosure clearly identified for
the particular space. Systems installed
without a stop valve shall be operated
by one control releasing at least the required amount of carbon dioxide.
(e) Where provisions are made for the
simultaneous release of a given amount
of carbon dioxide by operation of a remote control, provisions shall also be
made for manual control at the cylinders. Where gas pressure from pilot
cylinders is used as a means for releasing the remaining cylinders, not less
than two pilot cylinders shall be used
for systems consisting of more than
two cylinders. Each of the pilot cylinders shall be capable of manual control at the cylinder, but the remaining
cylinders need not be capable of individual manual control.
(f) Systems of the type indicated in
§ 34.15–5(d), which are of more than 300
pounds of carbon dioxide shall be fitted

arranged that the alarm will be sounded for at least 20 seconds before the
carbon dioxide is released into the
space. Such systems of not more than
300 pounds of carbon dioxide shall also
have a similar delayed discharge, except for spaces which have a suitable
horizontal escape.
(g) All distribution valves and controls shall be of an approved type. All
controls shall be suitably protected.
(h) Complete but simple instructions
for the operation of the systems must
be located in a conspicuous place at or

§ 35.01–45 Open hopper type barges—
B/ALL.
(a) With the exception of those open
hopper type barges constructed or
modified in conformance with the requirements of subpart 32.63 of this subchapter, the special operating conditions in this section apply to all other
open hopper type barges carrying those
cargoes listed in Table 30.25–1, of this
chapter, which are defined as:
(1) Flammable liquids having a Reid
vapor pressure in excess of 25 pounds
per square inch, absolute, in independent tanks (part 32 of this subchapter).
(2) Liquefied flammable gases (part 38
of this subchapter).
(b) All open hopper type barges, while
carrying in bulk any of the cargoes described in paragraph (a) of this section,
shall be operated in conformance with
the provisions in this section. However,
the provisions in this section are not
applicable to such barges when empty
(not necessarily cleaned or gas-freed).
(c)(1) Except as otherwise provided in
this section, no such open hopper type
barge shall be placed as a lead barge in
any tow. Such barges shall be placed in
protected positions within the tow so
that the danger from diving or swamping will be minimized. Where, due to
operating conditions, compliance with
this paragraph is impossible, the provisions of paragraph (c)(3) of this section
apply. The person in charge of the towing vessels shall be responsible for
compliance with this paragraph.
(2) No such open hopper type barge
shall be moved from a loading facility
unless all void spaces and bilges are
substantially free of water. Periodic inspections and necessary pumping shall
be carried out to insure the maintenance of such water-free conditions, in
order to minimize the free surface effect in both the longitudinal and transverse directions. Except when otherwise considered necessary for inspection or pumping, all hatch covers and
other hull closure devices for void
spaces and hull compartments shall be
closed and secured at all times. In the
case of unmanned barges, the person in
charge of the towing vessel shall be
deemed to be in charge of the barge,
and all requirements to be carried out
on the barge shall be carried out by or
under the direction of such person.
(3) When an open hopper type barge is
in an exposed position, such that protection from swamping provided by adjoining barges cannot be obtained from
location within the two alone, it shall
be the responsibility of the person in
charge of the towing vessel to control
speed so as to insure protection against
diving and swamping of the barge, having due regard to its design and
freeboard, and to the operating conditions.
(d) To show that special operating requirements apply to a specific open
hopper type barge, additional placards
or signs shall be displayed in at least
four different locations on the barge
when the cargoes described in paragraph (a) of this section are carried in
any form in the cargo tanks. The placards or signs shall be posted on the
barge approximately amidships on each
side and near the centerline of each

(2) Liquefied flammable gases (part 38
of this subchapter).
(b) All tank barges constructed or
modified in conformance with the requirements of subpart 32.63 of this subchapter are exempt from the provisions
of § 35.01–45.
(c) When it is necessary to operate
box or square-end barges as lead barges
of tows, the person in charge of the
towing vessel shall control the speed to
insure protection against diving and
swamping of such barges, having due
regard to their design and freeboard,
and to the operating conditions.
(d) All barges, while carrying in bulk
any of the cargoes described in paragraph (a) of this section, shall be oper-
ated in conformance with the provisions of this section. However, the provisions of this section are not applicable to such barges when empty and gasfreed.
(e) Barges shall not be moved from a
loading facility unless all bilges and
void spaces (except those used for
ballasting) are substantially free of
water. Periodic inspections and necessary pumping shall be carried out to
insure maintenance of such water-free
condition in order to minimize the free
surface effects, both in the longitudinal
and transverse directions. Except when
otherwise considered necessary for inspection or pumping, all hatch covers
and other hull closure devices for void
spaces and hull compartments other
than cargo spaces shall be closed and
secured at all times.
(f) During the time the cargo tanks
contain dangerous cargoes described in
paragraph (a) of this section in any
amount, in the liquid or gaseous state,
the barge shall be under constant surveillance.
(1) A strict watch of each unmanned
barge in tow shall be maintained from
the towing vessel while underway.
(2) A towing vessel engaged in transporting such unmanned barges shall
not leave them unattended. When a
barge is moored, but not gas free, it
shall be under the observation of a
watchman who may be a member of the
complement of the towing vessel, or a
terminal employee, or other person.
Such person shall be responsible for the

configuration (e.g. cylindrical, spherical, etc.) shall be designed, fabricated,
inspected, and tested in accordance
with the applicable requirements of
part 54 of subchapter F (Marine Engineering) of this chapter, except as otherwise provided for in this part.
(b) The requirements of this section
anticipate that cargo tanks constructed as pressure vessels will, by
themselves, constitute the cargo containment system and usually will not
require a secondary barrier.
(c) In the design of the tank, consideration shall be given to the possibility
of the tank being subjected to external
loads. Consideration shall also be given
to excessive loads that can be imposed
on the tanks by their support due to
static and dynamic forces under operating conditions or during testing. The
design shall show the manner in which
the tanks are to be installed, supported, and secured, and shall be approved prior to tank installation.
(d) Tanks with a service temperature
of minus 20° F. or lower and fabricated
of ferritic materials shall be stress relieved.
(e) Unlagged cargo tanks, where the
cargo is transported, at or near ambient temperatures, shall be designed for
the vapor pressure of the gas at 115° F.
The design shall also be based on the
minimum internal pressure (maximum
vacuum), plus the maximum external
static head to which the tank may be
subjected. Whenever surrounding cargo
is at a greater temperature than the
maximum allowable temperature of
the liquefied flammable gas tanks, the
liquefied flammable gas cargo is to be
such that the design pressure of the
liquefied flammable gas tank is not exceeded.
(f) Where cargo tanks, in which the
cargo is transported at or near ambient
temperature, are lagged with an insulation material of a thickness to provide
a thermal conductance of not more
than 0.075 B.t.u. per square foot per degree Fahrenheit differential in temperature per hour, the tanks shall be
designed for a pressure of not less than
the vapor pressure of the gas at 105° F.
The insulation material shall conform
to the requirements of § 38.05–20. The
design shall also be based on the minimum internal pressure (maximum
vacuum) plus the maximum external
static head to which the tank may be
subjected.
(g) Cargo tanks in which the temperature is maintained below the normal atmospheric temperature by refrigeration or other acceptable means
shall be designed for a pressure of not
less than 110 percent of the vapor pressure corresponding to the temperature
of the liquid at which the system is
maintained, or the pressure corresponding to the greatest dynamic
and static loads expected to be encountered either in service or during testing. For mechanically stress relieved
cargo tanks, additional factors relating
design pressure and maximum allowable pressure shall be as specified by
the Commandant. The material of the
tank shall satisfy the requirements of

§ 38.05–4 Design and construction of
nonpressure vessel type cargo
tanks—TB/ALL.
(a) The requirements in this section
anticipate a cargo containment system
consisting of a primary tank which is
structurally self-supporting and, where
required, a secondary barrier. Other
vessel or cargo tank configurations,
such as membrane type liners externally supported, will be considered
upon submission of substantiating
data, and based upon such additional
tests as the Commandant may direct.
(b) A secondary barrier is an arrangement or structure designed to contain
the cargo temporarily if leakage develops in the primary container. A secondary barrier shall be provided where
leakage from the primary container
may cause lowering of the temperature
of the ship’s structure to an unsafe
level. The secondary barrier shall be
constructed of material suitable to
contain the cargo at the service temperature.
(c) The design of the cargo containment systems shall be such that under
normal service conditions, or upon failure of the primary tank, the hull structure shall not be cooled down to a temperature which is unsafe for the materials involved. Structural members not
suitable for the service temperatures of
the cargo shall be protected by a secondary barrier consisting of suitable
structural containment together with
necessary associated insulation. Heat
transmission studies and tests may be
required to demonstrate that the arrangement is feasible and that the final
material temperatures are acceptable.
(d) The design and construction of
the cargo tanks shall be at least equiv-
alent to the standards established by
the American Bureau of Shipping or
other recognized classification society.
For special tanks, or designs not contemplated by standards of the classification society, a detailed analysis of
the entire tank, or designated parts
thereof, shall be made and submitted
to the Commandant for approval.
(e) The cargo tank shall be designed
for a head of cargo at least equal to the
highest level the liquid cargo may attain plus the maximum venting pressure. In no case shall a head of cargo
less than 4 feet above the cargo hatch
or expansion trunk be used.
(f) The design shall investigate the
thermal stresses induced in the cargo
tank during loading. Where necessary,
devices for spray loading or other
methods of precooling or cooling during loading shall be included in the design.
(g) All weld intersections or crossings
in joints of primary tank shells shall
be radiographed for a distance of 10
thicknesses from the intersection. All
other welding in the primary tank and
in the secondary barrier shall be spot
radiographed in accordance with the
requirements of part 54 of subchapter F
(Marine Engineering) of this chapter.

vessel type tanks, the hydrostatic test
pressure shall mean the pressure specified in § 38.25–1(d), while the maximum
allowable pressure shall mean the maximum venting pressure as used in
§ 38.05–4(e). Where it is not feasible to
attach the nameplate to the tank, it
shall be conspicuously displayed nearby.

(2) Cargo tanks installed in barges
shall comply with the requirements of
§ 32.63–25 of this subchapter.
(b) Foundations, and stays where required, shall be designed for support
and constraint of the weight of the full
tank, and the dynamic loads imposed
thereon. Thermal movement shall also
be considered.
(c) Foundations and stays which may
be exposed to the cargo shall be suitable for the temperatures involved and
be impervious to the cargo.
(d) The design of the foundations and
stays shall consider the resonance of
the cargo tank, or parts thereof, and
the vibratory forces, found in the tank
vessel. If necessary, effective damping
arrangements shall be provided.
(e) Independent containment systems
shall be so arranged as to provide a
minimum clearance of not less than 24
inches from the vessel’s side and not
less than 15 inches from the vessel’s
bottom to provide access for inspection
of the hull. Clearances for collision
protection, where required by other
parts of the regulations in this subchapter, may increase the clearances
specified here.
(1) For pressure vessel type tanks the
distance between adjacent tanks and
between tanks and vessel’s structure
shall be adequate to permit access for
inspection and maintenance of all tank
surfaces and hull structure as approved
by the Commandant. Alternate provisions may be made for inspection and
maintenance of the vessel’s structure
and tanks by moving such tanks or by
providing equivalent acceptable means
for remote inspection.
(2) For nonpressure vessel type containment systems, access shall be arranged to permit inspection of one side
each of the primary tank and secondary barrier, under normal shipyard
conditions.
Containment
systems
which, because of their peculiar design,
cannot be visually inspected to this degree, may be specially considered provided an equivalent degree of safety is
attained.
(f) Cargo tanks may be installed on
deck, under deck, or with the tanks protruding through the deck. All tanks
shall be installed with the manhole
openings located in the open above the
weather deck. Provided an equivalent
degree of safety is attained, the Commandant may approve cargo tanks installed with manhole openings located
below the weather deck.
(g) For pressure vessel type cargo
tanks, the following conditions apply:
(1) Liquefied flammable gas cargo
tanks may be located in cargo tanks or
in spaces which meet the requirements
for cofferdams as defined in § 30.10–13 of
this subchapter. When liquefied flammable gas cargo tanks are installed in
cargo tanks, such cargo tanks may be
used simultaneously or separately for
the carriage of flammable or combustible liquids up to and including the
grade for which the cargo tanks are
otherwise certified in accordance with
the requirements of this subchapter.
(2) Where the liquefied flammable gas
tanks are installed in cargo tanks and
a portion of the liquefied flammable
gas tanks extend above the weather
deck, the penetration shall be made
gastight and watertight, and shall be
such as to provide full compliance with
