Engineering · Watchstanding — UMS
On a vessel certified for unmanned machinery space (UMS) operation, the engine room is unmanned at night because it is fitted with:
- AA larger crew
- BTwice the fuel capacity
- CA second main engine
- DAutomated monitoring, alarms, fire detection, and a bridge/engineer alarm system that calls the duty engineer✓ Correct
Explanation
UMS-class machinery spaces have extensive automation: machinery and bilge alarms, fire detection, an engineers' alarm and a dead-man (watch) alarm, and bridge control of propulsion — allowing safe periodic-unattended operation.
