This document outlines procedures for responding to a main engine failure, which can be dangerous if the vessel is maneuvering or in rough weather. Immediate actions include stopping the engine if not already stopped, informing the chief engineer and master, and logging events. The chief engineer will lead an engine room team to assess damage and repairs while the master leads a bridge team to communicate with the engine room, engage backup steering, and take navigational actions as needed like anchoring. Once repairs are complete, a detailed incident report is prepared covering the failure details, repairs, and recommendations.
