Description of Incident

An electric chain hoist on the beam above one of the main engines in a vessel, was left unattended after use. The chain hook paid out and coiled the chain onto the running main engine close to the generator drive shaft. The incident occurred when the chain hoist was being used to lower spare parts required for maintenance in the engine room. Two lifts took place above the running main engine. After their completion, the chain block was lifted into its highest position.

Later on, during routine rounds, the motorman observed the hoist’s chain with hook to have “paid out” fully and created a dangerous condition near to main engine no.3. The chain was made safe and then removed from service for inspection.
