Safety & Troubles

5 lessons

When engines misbehave: protections, performance curves, starting and running faults, and the emergencies — with causes and actions.

This chapter collects 5 illustrated lessons on Safety & Troubles as part of Marine Propulsion & Diesel Engines, ordered as they are best studied. It opens with Safe Engine Room Watchkeeping: UMS Certification, Physical Rounds, Automation Safeguards & Emergency Response, Engine Protections, Vibration Watch & Performance Curves, Marine Diesel Engine Starting & Running Troubles: Fault Trees, Knock Diagnosis & Emergency Response, Crankcase Explosions, Oil Mist Detectors & Relief Valves, Scavenge Fires, Trunk Safety & Relief Devices. Each lesson is written for MEO oral and written preparation: definitions first, then how the system behaves, then the checks and figures used in practice.
