Question 1

You've confirmed water is entering a watertight compartment, likely from minor hull damage. Your crew has limited technical knowledge of the vessel's stability. What should systematic troubleshooting look like under this pressure?

Accepted Answer

Work through a structured sequence: identify the source, estimate the rate of ingress, confirm which compartments are affected, and assess remaining stability before deciding next steps SHK's investigation found the crew lacked systematic troubleshooting and had limited technical knowledge of the vessel's systems and stability, which contributed to a delayed and disorganised response. A structured sequence — source, rate, compartments, remaining stability — is what turns a stressful, reactive situation into a manageable one, especially when technical knowledge is limited.

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.
