1. The purpose of the International Code for the Construction and Equipment of Ships
Carrying Liquefied Gases in Bulk (IGC Code) is to provide an international standard for the
safe carriage by sea in bulk of liquefied gases and certain other substances listed in chapter
19 of the IGC Code, by prescribing the design and construction standards of ships involved
in such carriage and the equipment they should carry so as to minimize the risk to the ship,
to its crew and to the environment, having regard to the nature of the products involved.
1. ☒ True
2. ☐ False
2. The IGC Code applies to ships regardless of their size, including those of less than 500 tons
gross tonnage, engaged in carriage of liquefied gases having a vapour pressure exceeding
2.8 bar absolute at a temperature of 37.8°C, and other products as shown in chapter 19 of
the IGC Code, when carried in bulk
1. ☒ True
2. ☐ False
3. The structure, equipment, fittings, arrangements and material (other than items in respect
of which a Cargo Ship Safety Construction Certificate, Cargo Ship Safety Equipment
Certificate and Cargo Ship Safety Radio Certificate are issued) of a chemical tanker shall be
subjected to the following surveys:
1. ☐ an initial survey before the ship in put in service or before the International
Certificate of Fitness for the Carriage of Liquefied Gases in Bulk is issued for the first
time, which should include a complete examination of its structure, equipment,
fittings, arrangements and material in so far as the ship is covered by the Code. This
survey should be such as to ensure that the structure, equipment, fittings,
arrangements and material fully comply with the applicable provisions of the Code;
2. ☐ a renewal survey at intervals specified by the Administration, but not exceeding 5
years. The renewal survey should be such as to ensure that the structure, equipment,
fittings, arrangements and material fully comply with the applicable provisions of the
Code;
3. ☐ an intermediate survey within 3 months before or after the second anniversary
date or within 3 months before or after the third anniversary date of the Certificate
which should take the place of one of the annual surveys. The intermediate survey
should be such as to ensure that the safety equipment, and other equipment, and
associated pump and piping systems fully comply with the applicable provisions of the
Code and are in good working order. Such intermediate surveys should be endorsed
on the Certificate issued;
4. ☐ an annual survey within 3 months before or after each anniversary date of the
Certificate, including a general inspection of the structure, equipment, fittings,
arrangements and material to ensure that they have been maintained and that they
remain satisfactory for the service for which the ship is intended. Such annual surveys
should be endorsed on the Certificate issued;
5. ☒ All of the above

4. Ships subject to the IGC Code should be designed to one of the following standards:
1. ☐ Type 1G ship is a gas carrier intended to transport products indicated in chapter 19
which require maximum preventive measures to preclude the escape of such cargo.
2. ☐ Type 2G ship is a gas carrier intended to transport products indicated in chapter 19
which require significant preventive measures to preclude the escape of such cargo.
3. ☐ Type 2PG ship is a gas carrier of 150m in length or less intended to transport
products indicated in chapter 19 which require significant preventive measures to
preclude escape of such cargo, and where the products are carried in independent
type C tanks designed for a MARVS of at least 7 bar gauge and a cargo containment
system design temperature of -55°C or above. Note that a ship of this description but
over 150m in length is to be considered a Type 2G ship.
4. ☐ Type 3G ship is a gas carrier intended to carry products indicated in chapter 19
which require moderate preventive measures to preclude the escape of such cargo.
5. ☒ All of the above are correct answers

5. Shipside discharges below the freeboard deck: The provision and control of valves fitted to
discharges led through the shell from spaces below the freeboard deck or from within the
superstructures and deckhouses on the freeboard deck fitted with weathertight doors
should comply with the requirements of the relevant regulation of the International
Convention on Load Lines in force, except that the choice of valves should be limited to:
1. ☐ one automatic non-return valve with a positive means of closing from above the
freeboard deck; or
2. ☐ where the vertical distance from the summer load waterline to the inboard end of
the discharge pipe exceeds 0.01L, two automatic non-return valves without positive
means of closing, provided that the inboard valve is always accessible for examination
under service conditions.
3. ☒ All of the above are correct answers

6. Cargo tanks should be located at the following distances inboard:

1. ☐ Type 1G ships: from the side shell plating not less than the transverse extent of
damage and from the moulded line of the bottom shell plating at centreline not less
than the vertical extent of damage and nowhere less than 760 mm from the shell
plating.
2. ☐ Types 2G/2PG and 3G ships: from the moulded line of the bottom shell plating at
centreline not less than the vertical extent of damage and nowhere less than 760 mm
from the shell plating.
3. ☐ All of the above are correct answers

7. Hold spaces should be segregated from machinery and boiler spaces, accommodation
spaces, service spaces and control stations, chain lockers, drinking and domestic water
tanks and from stores. Hold spaces should be located forward of machinery spaces of
category A, other than those deemed necessary by the Administration for the safety or
navigation of the ship.
1. ☒ True
2. ☐ False

8. Cargo pump rooms and cargo compressor rooms should be situated above the weather
deck and located within the cargo area unless specially approved by the Administration.
Cargo compressor rooms should be treated as cargo pump rooms for the purpose of fire
protection according to SOLAS regulation II-2/9.2.4.
1. ☒ True
2. ☐ False
9. Any cargo control room should be above the weather deck and may be located in the
cargo area. The cargo control room may be located within the accommodation spaces,
service spaces or control stations provided the following conditions are complied with:
1. ☐ the cargo control room is a gas-safe space; and
2. ☐ if the entrance complies with 3.2.4 of the IGC Code, the control room may have
access to the spaces described above;
3. ☐ if the entrance does not comply with 3.2.4 of the IGC Code, the control room
should have no access to the spaces described above and the boundaries to such
spaces should be insulated to A-60 class integrity.
4. ☒ All of the above
10. Access to spaces in the cargo area should be provided to:
1. ☐ cargo tanks direct from the open deck;
2. ☐ through horizontal openings, hatches or manholes, the dimensions of which
should be sufficient to allow a person wearing a breathing apparatus to ascend or
descend any ladder without obstruction and also to provide a clear opening to
facilitate the hoisting of an injured person from the bottom of the space; the
minimum clear opening should be not less than 600 mm x 600 mm; and
3. ☐ through vertical openings, or manholes providing passage through the length and
breadth of the space, the minimum clear opening of which should be not less than
600 mm by 800 mm at a height of not more than 600 mm from the bottom plating
unless gratings or other footholds are provided.
4. ☒ All of the above
