Question 1

You've confirmed a fine fuel spray near the auxiliary engine's high-pressure fuel pump. The nearest hot surface — the exhaust manifold — is close by. What's the priority?

Accepted Answer

Treat this as an active fire risk requiring immediate action — shut down the affected engine if possible and prevent any ignition source from reaching the spray Atomised fuel contacting a hot exhaust surface can ignite almost instantly, according to Skuld's guidance. Once a fine mist near a high-pressure pump is confirmed close to a known hot surface, this is an active fire risk requiring immediate shutdown and isolation — not a wait-and-monitor situation.

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.
