hypothetical Q: If a centrifugal p/p driven by the engine (or any type of P/p)is fitted for fresh water cooling duties, how will it function when the engine is reversed?
any ideas will help..

Of course, the engine is not usually reversed - the transmission does this in most applications.

Cooling pumps on all large marine diesels are normally independently driven because they are used to keep the engine warm by circulating heated water when the engine is at rest but if this were not an issue the same system could be used as for the LO pumps.
Fuel transfer pumps in this case are electrically driven pumps used to transfer fuel from storage tanks to service tanks. Circulating and supply pumps are independent because they have to keep the Heavy fuel oil circulating and warm
(it solidifies if cold) and the injection pumps are cam driven from a reversible camshaft.
hope this helps
