Fire in diesel generator following tests
What happened
There was a small fire in the engine room on a vessel in port. The incident occurred when a diesel generator was being maintained by a third-party maintenance team. On completion of a change of alternator bearings, the generator was tested at idling speed, and no problem was found.

The alarm was raised; the diesel generator was brought to an emergency stop and the fire was put out with an extinguisher.
