Question 1

What if, during your rounds in the engine room, you noticed a generator running slightly hotter than usual, or a faint smell you couldn't place — but nothing was alarming yet and the engine "seemed fine"? Based on the lessons of Kommandor Susan, what should you do?

Accepted Answer

Report it immediately to the duty engineer, even if it seems minor — early warning signs like unusual heat, smell or vibration are often the only visible clue of a latent failure building toward a major event Kommandor Susan's DG1 ran for six years with non-genuine bearings before catastrophic failure — a classic "latent failure" that looked fine right up until it wasn't. The MAIB's broader point is that systems which "appear to work" can be concealing a developing fault. A rating who notices something slightly off and reports it promptly gives the engineering team the chance to investigate before a minor anomaly becomes a major failure. Self-fixing symptoms without reporting them removes that early-warning opportunity entirely.

Question 2

You're draining a thermal oil system that was running normally a short time ago. Before opening the drain point, what should you confirm?

Accepted Answer

That the system has cooled and depressurised, and you are positioned clear of the drain point's discharge path On the dredger MV Amazone, two crew members draining a thermal oil system after months of contamination were sprayed with hot oil, suffering severe burns. The investigation found company procedures lacked clear instructions for safe drainage — confirming the system has cooled and depressurised, and standing clear of the discharge path, are essential before opening any drain point on a hot oil system.

Question 3

A thermal oil system has been contaminated and needs draining for cleaning. The written procedure tells you to open the drain valve but doesn't specify a cooling-down period or PPE. What should you do?

Accepted Answer

Treat the gap as a hazard in its own right: apply a suitable cooling/depressurising period and full PPE before proceeding, and raise the procedure gap with the Chief Engineer The FEBIMA investigation into the MV Amazone incident found that although the crew followed company procedures, those procedures lacked clear instructions for safely draining a thermal oil system. A procedure that's silent on cooling time and PPE for a hazardous task is a gap to be closed before the job starts — not a green light to skip those precautions.
