Question 1

What is the purpose of the emergency generator fitted aboard, and what checks would you expect to be part of routine engine room duties relating to it?

Accepted Answer

The emergency generator provides electrical power to essential services (such as emergency lighting, steering gear, fire pumps, and communications equipment) if the main source of electrical power fails; routine checks typically include confirming the starting batteries are charged, the fuel supply is adequate and the quick-closing fuel valve is operable, and that the generator starts and runs correctly during periodic tests A total loss of main electrical power ("blackout") is one of the most serious situations a vessel can face, particularly during manoeuvring, cargo operations, or in restricted waters — the emergency generator is designed to start automatically (or be started manually if automatic start fails) and supply a limited set of essential loads, not to replace full main power. Routine readiness checks (battery condition, fuel availability, periodic test runs) exist because a backup system that has not been verified to work is not a reliable backup, and emergency generator failures during drills are a common finding that gets flagged for corrective action.

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.
