Question 605Steam Plants - Assistant Engineer

The correct answer is C) Seal off the leak and promptly remove and replace all contaminated oil from the system. This is the correct answer because salt water contamination of the main lubricating oil system can have serious consequences for the engine's operation and longevity. Allowing the circulation of contaminated oil (option A) or delaying the removal of the contaminated oil (option D) risks further damage to the engine. Disengaging the jacking gear (option B) does not address the core issue of the contaminated oil. The proper remedial action is to quickly seal off the leak to stop further contamination, and then completely drain and replace the contaminated oil in the system. This prevents the circulation of damaging salt water through the engine components and ensures the oil system is restored to a proper, uncontaminated state.
