The Marine Safety Forum published Safety Alert 20-11 relating to a potential dropped object in a load.

What happened?

The near miss incident occurred during offloading of casing from a supply vessel.  

The rig crew spotted a hook resting on the bundle.  The load was set down and the job stopped.

The hook was later identified as part of the vessel’s cargo securing equipment which had been found defective before use but had not placed in the quarantine area for damaged lifting and securing equipment.

The weight of the hook was 1.4 kg. The hook could have fallen 19 m on the rig and significantly higher (70m +) to the supply vessel deck.
