Rest hours, fatigue and an instruction to cover additional watches
You are the third engineer on a bulk carrier during a four-day port stay. In the last 24 hours you have had 4 hours’ rest in two blocks (0200–0400 and 0530–0730) because of cargo operations and a ballast pump failure. The second engineer has been hospitalised ashore with appendicitis; the chief engineer asks you to take the 0000–0400 watch tonight, supervise bunkering from 0600, and then work the 0800–1200 watch tomorrow. The vessel is scheduled to sail at 1400 tomorrow. You are already showing signs of fatigue: you made a paperwork error on the bunker requisition an hour ago. The master is on the bridge and the chief engineer says there is no one else.
1. Assess the proposed schedule against STCW rest-hour requirements and decide what you do.
Read the worked answer
STCW Section A-VIII/1 requires at least 10 hours of rest in any 24-hour period and 77 hours in any 7-day period. Rest may be divided into no more than two periods, one of which must be at least 6 hours long, and the interval between consecutive rest periods must not exceed 14 hours. Drills and emergencies are limited exceptions, not a routine fix for manning gaps.
My current 24 hours already show only 4 hours’ rest in two short blocks and no 6-hour continuous period. Adding 0000–0400 and 0800–1200 would leave essentially no rest and would breach both the 10-hour and 6-hour requirements. The paperwork error is an early warning sign of fatigue.
Decision: I would not accept the schedule as proposed. I would tell the chief engineer that the plan is non-compliant and unsafe, and propose alternatives: reduce or reschedule bunkering, use the duty deck officer and bunker surveyor for supervision, delay cargo operations, obtain shore assistance, or have the master reallocate watchkeeping duties. I would ask for the rest-hour record to be corrected and the fatigue risk reported.
2. How do you communicate this and what records do you make?
Read the worked answer
Communication should be calm, factual and early - before the watch is due, not at the last minute. I would speak to the chief engineer first, then the master if needed, setting out the actual rest hours, the STCW limits, the error I made and the specific risk on a bunkering operation (a fuel spill, overflow or wrong tank is a classic fatigue accident). I would propose a workable alternative rather than simply refusing.
Records:
- Rest-hour records showing the true hours, not a reconstructed compliant version.
- A fatigue report/non-conformity in the SMS.
- Note in the engine log or handover book of the manning shortfall and the agreed mitigation.
- Bunker plan showing who is supervising, with a competent deputy named.
Reasoning: accurate records protect the engineer and give the company the evidence it needs to fix manning. Falsifying rest hours would hide the risk and is itself an offence. The handover must state clearly who is in charge of each operation.
3. If the master orders you to work the schedule anyway, what are your options and what minimum mitigations would you insist on?
Read the worked answer
The master has overriding authority for safety, but that authority does not make a false rest-hour record lawful. If ordered, I would state my objection, ask for the order to be recorded, and comply only to the extent that I can remain safe. I would then report the matter to the DPA and, if necessary, the flag State; the company’s confidential reporting line exists for this situation.
Minimum mitigations I would insist on:
- A named competent deputy for the bunkering, with clear handover and no simultaneous watchkeeping.
- Bunkering slowed or rescheduled to daylight, with the deck duty officer and surveyor present.
- A short uninterrupted rest period before the 0000 watch, and relief during the 0800–1200 watch.
- No solo manoeuvring or critical machinery work while fatigued; the chief engineer to be available.
- A fatigue entry in the SMS and a realistic plan to obtain a relief engineer at the next port.
Reasoning: the aim is to keep the ship safe, not to win the argument. Documenting the objection and the mitigation protects the engineer if an incident follows, and the manning shortfall must be escalated because it will not fix itself.
