The temperatures I gave are measured with an IR gun on the oil pan. The plate exchanger was sized by the engine manufacturer to provide adequate oil cooling at full load. Next time I'm on vessel I'll send you some pictures of what is happening.
The first time I saw a plate exchanger for cooling diesel engine oil was about 50 years ago on a Cat loader. Plate exchangers for heating and cooling are used in all sorts of industrial applications going back over a century.
