The system includes two circuits. The freshwater
system is cooling the cylinder liners and the cylinder
heads. An engine driven cooling water pump
circulates the coolant through the heat exchanger and
through the engine. The raw water system is cooling
the coolant in the freshwater cooling system. The raw
water system is connected to a seawater inlet or a
central cooling system.
