“You have a crankcase oil mist detector alarm. Do you stop the engine?”

After starting a refrigeration compressor, the oil separator return valve should only be opened once the unit has warmed up . Stcw Test Engine Management Slow Speed Answers

“A scavenge fire occurs due to oil mist or carbon deposits igniting by blow-past gases (hot combustion leaks past piston rings). In a crosshead engine, the scavenge air receiver is below the cylinder liner.” “You have a crankcase oil mist detector alarm

: Management level engineers are responsible for planning major overhauls. The exam tests knowledge on piston pulls, liner measurements, and bearing inspections. Beyond the hardware, it emphasizes Engine Room Resource Management (ERRM) —the ability to lead a team effectively during high-pressure situations or complex repairs. In a crosshead engine, the scavenge air receiver

I have my team record turbocharger RPM, scavenge pressure, and exhaust gas inlet temperature every watch. A drop in scavenge pressure at constant RPM is the early warning.”

“No, I do not stop immediately. I reduce to dead slow, evacuate the engine room, and engage remote monitoring. Stopping can cool the crankcase rapidly, condensing oil mist and hiding the hot spot. I investigate using a thermal camera on the crankcase door first.”

Navigating the examination is a critical milestone for senior marine engineers moving into leadership roles. This assessment, often delivered via the Seagull Crew Evaluation System (CES) , focuses on the operational nuances of large two-stroke crosshead diesel engines and the regulatory frameworks governing them.
