13.5 Fuel Oil Tanks
13.5.1 Arrangements of Structural Tanks
13.5.1(a) Machinery space of category A. As far as practicable, fuel oil tanks are to be part of the
vessel’s structure and located away from the machinery spaces of category A. However, where it
is found necessary to locate the fuel oil tanks adjacent to or inside the machinery spaces of
category A, the arrangements are to reduce the area of the tank boundary common with the
machinery space of category A to a minimum, and to comply with the following:
i) Fuel tanks having boundaries common with machinery spaces of category A are not to
contain fuel oils having flash point of 60°C (140°F) or less.
ii) At least one of their vertical sides is to be contiguous to the machinery space boundary.
iii) (2002) The bottom of the fuel oil tank is not to be so exposed that it will be in direct
contact with flame should there be a fire in a Category A machinery space. The fuel tank
is to extend to the double bottom. Alternatively, the bottom of the fuel oil tank is to be
fitted with a cofferdam. The cofferdam is to be fitted with suitable drainage arrangements
to prevent accumulation of oil in the event of oil leakage from the tank.
iv) Fuel oil tanks are to be located such that no spillage or leakage therefrom can constitute a
hazard by falling on heated surfaces or electrical equipment. If this is not practicable, the
latter are to be protected from such spillage or leakage by shields, coamings or trays as
appropriate. |
