NWKO was at the stern, and he was communicating with bridge and the jacket. Chief officer ordered NWKO to cast off from the jacket. When one rope was left, the NWKO replied that he had let all the ropes off. On hearing this, chief officer gave Full Ahead on the engines, to get off from the jacket as fast as possible.

It cut his neck off before parting.After this incident, the company instructed that only chief officer can be at the stern during casting off and the Master has to be at the engine controls on the bridge.
