Watchkeeping, Engineering Practice and Resource Management

Watchkeeping, Engineering Practice and Resource Management

The exam checks the routines of the engineering watch and the non-technical skills that prevent accidents.

Taking over and keeping watch

  • Take over only when satisfied: parameters normal, outstanding defects known, work in progress and isolations listed, bridge informed.
  • Round the machinery spaces at intervals; log pressures, temperatures, levels and fuel consumption; read trends, not only alarm limits.
  • UMS: confirm alarm and dead-man systems are working, the bridge is manned and the duty engineer is within call.
  • Handover is face to face, with anything abnormal stated explicitly. Never hand over an unresolved alarm.

Communications and resource management

  • Closed loop: order given, received, repeated back, confirmed, then reported when done.
  • Challenge and response: anyone may question an unsafe instruction; the authority gradient must let a junior say stop.
  • Situational awareness, workload, fatigue, a short-term strategy for the next watch, toolbox talks before jobs, debriefs after drills.

Worked example

At 03:40 under UMS the high bilge level alarm sounds in the engine room.

  1. Acknowledge on the panel and inform the bridge at once, because propulsion may be at risk.
  2. Call the duty engineer and, if the level is rising, the second engineer.
  3. Use CCTV and tank soundings to find the source before entering; take a torch and radio, and never enter alone where flooding or electrical damage is possible.
  4. Line up the standby bilge pump and check whether the automatic pump tripped; find the cause before restarting.
  5. Record times, actions and readings, and report to the chief engineer.

Traps

Silencing an alarm and going back to the cabin; entering a space alone to look for water; restarting a tripped pump without finding the cause; vague orders with no repeat-back; leaving the engine room unattended with no one on the bridge.
