in which independent tanks are located, cofferdams surrounding integral
tanks and the following deck areas:
-
.1 within 3 m of a cargo tank installed on deck;
-
.2 within 3 m of a cargo tank outlet in case of
independent tanks installed below deck;
-
.3 within 3 m of a cargo tank outlet in case of
integral tanks installed below deck and separated from the weather

-
.4 the deck area above an integral tank without
an overlaying cofferdam plus the deck area extending transversely
and longitudinally for a distance of 3 m beyond each side of the tank;
-
.5 within 3 m of any cargo liquid or vapour pipe,
flange, cargo valve, gas or vapour outlet, or entrance or ventilation
opening to a cargo pump-room.
1.3.2
Deadweight means the difference
in metric tons between the displacement of an offshore support vessel
in water of a density of 1.025 at the load waterline corresponding
to the assigned summer freeboard and the lightweight of the ship.
1.3.3
Lightweight means the displacement
of an offshore support vessel in metric tons without cargo, fuel,
lubricating oil, ballast water, fresh water and feed water in tanks,
