Fuel system
The craft is refuelled through a filling hose and a filling valve provided at the superstructure top on the port side.
Fuel is fed to the main engine from a service tank with a capacity enabling the craft to cruise 8 hrs without refueling. In addition, there is a 400-litre storage tank between frames 31 and 33 on the starboard side which contains a 2-hr fuel reserve to be used in emergency. The same tank supplies fuel to a water heater. For filling the reserve tank, use is made of a hand-operated pump with a delivery rate of 1.2 cub.m/hr. The same pump may be used for defueling purposes and as a stand-by engine priming pump. Serving as the main engine priming pump is a unit with a delivery rate of 16 or 17 litres/min at a delivery pressure of 3 kgf/sq.cm at the outlet. The service and storage tanks are equipped with all the necessary fittings and vent pipes with fire protectors. The delivery line stop valves of both the tanks are remotely operated from the bulkhead at frame 31.
The ullage in the service tank is taken by a dip stick whereas the storage tank is equipped with a liquid level gauge glass. The fuel piping is in aluminium and the fittings in brass and light alloy.
Lub oil system
A supply of oil to lubricate the main engine and auxiliaries is contained in a 150-litre main tank capable of catering for all the needs during an 8-hr. cruise. For filling the tank, use is made of a hose applied to a filling valve located at the superstructure top on the port side.
