While standing watch on a ship in the engine room with marine gas turbine engines as shown in the illustration, if after reducing power in response to a high lube oil supply temperature alarm, the temperature continues to increase, your next step should be to __________. Illustration GT-0017

Correct Answer: Option B — shutdown the engine

A rising lube oil temperature despite power reduction indicates a critical failure in the cooling or lubrication system, such as a heat exchanger blockage or internal bearing distress. Immediate shutdown is mandatory to prevent catastrophic mechanical failure, bearing seizure, or fire resulting from overheated oil and potential seal degradation.
