What should be monitored closely during rough weather conditions regarding lubrication systems?

In rough weather conditions, oil pressure levels in lubrication systems should be monitored closely due to the critical role they play in maintaining engine integrity and performance. When a vessel is subjected to heavy seas, the motion can cause fluctuations in oil distribution and affect the lubrication supply to moving parts within the engine. If oil pressure drops too low, it can lead to inadequate lubrication, increasing the risk of engine wear, overheating, and potential seizure, ultimately disrupting the operation and safety of the vessel.

Maintaining optimal oil pressure is essential to ensure that all components receive the necessary lubrication, preventing damage and extending the life of the machinery. By closely monitoring oil pressure levels, engineers can respond promptly to any deviations, ensuring the lubrication system performs effectively even under challenging conditions.

While fuel throughput, system noise levels, and temperature fluctuations are also important parameters to keep an eye on, they do not directly relate to the immediate concerns of lubrication efficacy and component protection in the face of rough weather.
