Bilge and firefighting system, operating in all watertight compartments of the vessel, of capacity calculated according to Class standards, will be installed in accordance with good shipbuilding practice. System will be operated by three pumps: main bilge pump, firefighting pump, and chain locker pump. Main bilge pump and pump servicing main firefighting line will be interchangeable through the use of valves. Anchors flushing will be carried by use of firefighting line.
Chain locker pump, independent from the main system, will be discharging directly overboard. Bilge and firefighting pipelines to be of steel; fittings: steel, cast steel and cast iron.


Fuel system, supplying main engines and generators, will be arranged and installed in accordance with good marine practice and Class Regulations. In general, there will be five integrated fuel tanks and one day tank installed. Fuel transfer shall be by means of fuel transport pump (or emergency hand pump), through fuel manifold.
