Seawater cooling system
The seawater cooling system is used to cool the engine and the charge air cooling system. For full engine
power at the permissible thermal loads it is very important that the charge air cooling system has an
adequate supply of sea water.
The cooling system on all MAN engines is designed for seawater temperatures of up to 32°C (305 K).
