A main diesel engine on your platform supply vessel has experienced a safety shutdown due to excessive crankcase pressure. What is the appropriate response?
⢠Crankcase explosions and how they start (oil mist, hot spots, ignition) ⢠Manufacturer and class society guidance on opening a crankcase after a suspected crankcase explosion risk ⢠Why cooling time is critical before restarting or opening a diesel engine after a high crankcase pressure trip
⢠What danger exists if you open a hot crankcase or restart a diesel engine immediately after a high crankcase pressure shutdown? ⢠Which option best shows a cautious, safety-first approach that prevents a secondary explosion or fire? ⢠In real life, what would a chief engineer or safety manual emphasize before letting you open or restart this engine?
⢠Verify which choice mentions adequate cooling time before either opening the crankcase or restarting the engine. ⢠Check which options ignore the safety shutdown and suggest immediate action that could put personnel at risk. ⢠Confirm that the chosen response includes finding and correcting the cause of the high crankcase pressure before attempting another start.
