About the role

This interview covers the day-to-day engineering responsibility expected of a Third Engineer, including auxiliary machinery, watchkeeping and maintenance. The panel wants evidence that you diagnose faults methodically, control hazards before work and leave accurate records for the next watch and senior engineers.

How to prepare

  1. Revise the operating principles and common failures of generators, purifiers, pumps, compressors and cooling systems.
  2. Prepare examples of faults you diagnosed from trends, alarms and equipment checks.
  3. Review safe isolation, permit to work and return-to-service steps for machinery maintenance.
  4. Practise describing your engine-room watch handover in a clear sequence.
  5. Check the official issuing body for current licence and certificate rules relevant to the role.

Common mistakes

  • Jumping to component replacement before explaining how you would confirm the fault.
  • Leaving isolation, permits or communication out of a maintenance answer.
  • Listing machinery theory without connecting it to readings, alarms and practical checks.
