Engineering Watchkeeping and Operational Procedures: Standby, Handover and Records
This domain tests how an engineer stands a watch: STCW watchkeeping principles, rest-hour limits, handover discipline, unmanned machinery space operation, standby for manoeuvring, and the records that prove it all happened. Questions are scenario-based, so the answer is usually the correct procedure rather than a fact.
Core rules
- Minimum rest: 10 hours in any 24-hour period and 77 hours in any 7-day period, with at least one rest period of 6 hours continuous; watch schedules must be posted.
- Handover must be face to face and must include plant condition, ongoing work and permits, abnormal readings, and defects affecting operation.
- Before departure, steering gear is tested within 12 hours, telegraphs and alarms tested, and standby is manned before manoeuvring begins.
- Fuel changeover to distillate is completed with sufficient lead time for viscosity at the injectors to be correct before manoeuvring.
- Oil Record Book entries must be made without delay, signed by the officer in charge and each completed page signed by the Master.
Worked example
A watchkeeper works 00:00-04:00, rests 04:00-10:00 (6 hours continuous), works 10:00-14:00, rests 14:00-16:00 (2 hours), works 16:00-20:00, rests 20:00-22:00 (2 hours), then works 22:00-24:00. Total rest is 6 + 2 + 2 = 10 hours, including one continuous 6-hour block, so the 24-hour requirement is met. The 7-day total of 77 hours must still be verified separately.
Traps
Relying on a verbal handover with no log entry; starting manoeuvring before the fuel viscosity has stabilised; and making belated Oil Record Book entries, which is a record-keeping offence even when the discharge was legal.
