adequate area for handling mooring lines should be left free of cargo at the stern of the vessel if the vessel is securing to the installation. If it is necessary to carry deck cargo in the area that the crew require for mooring activities, such cargo should be discharged to the installation before the vessel is moored.

Unusual cargo items

All tubular backloads should be indicated to the vessel in good time to allow for planning of stowage. Tubular cargoes should be pre-slung in bundles or singly and secured by bulldog grips or other equivalent methods to prevent slippage. All pipe lifts should be slung so as to be level. Varying lengths of sling in one lift should not be used.

Other operations, bulk handling etc., may have to be suspended whilst heavy lifts are underway. Subject to agreement with the person in command, taglines may be attached to heavy or large lifts, if considered necessary to aid handling.

Crane Operations

For offshore crane operations a safety pendant ('Stinger') of sufficient length should be provided between either the headache ball or floating block and the hook, all of which should be of high visibility colour. The tag line attached to the 'Stinger' should be a minimum diameter of 12mm and not too short or too long to create a hazard.

The 'Stinger' and hook must be of an appropriate SWL for the lifts being worked. The installation should have a selection available for the type of cargo that is normally handled. The lighter the weight of the 'Stinger' and hook, the less hazardous it is for the deck crew on a moving ship to handle, provided that it is of sufficient SWL.

For routine cargo operations, only swivel self-locking safety hooks should be used. For non-routine cargo, alternative hooks or lifting gear as agreed between the person in command and OIM may be used, providing that such equipment is fit for the purpose.

The crane driver should always have a clear view of the vessel's deck and have direct radio communication to the bridge of the vessel. Directions given to the crane driver by the deck crew on the vessel must only be given by one person who has been designated to perform that function.

Consideration must be taken of impact loadings caused by the vertical movement of the craft in the swell when the weight of the cargo is taken by the crane.

When planning the loading ashore, containers and pre-slinging arrangements should be suitably de-rated to take account of the expected sea conditions during discharge at the offshore installation.

As far as is practicable, all crane lifts made from or onto a supply vessel should not be lifted
