taken not to use excessive amounts of power on the vessel's propulsion.

The crew should be off the deck and in a protected location during chasing operations.

Grappling

Care should be taken deploying grapples and 'J' hooks over the stern. If the weight suddenly comes on the pendant wire it may whip across the deck. This hazard can be addressed by using the vessel's tow pins.

Excessive power or speed may cause sudden overloading on equipment when the grapple or 'J' hook encounters the cable.

Recovering Anchors

Care should be taken when lifting anchors, especially those that are deeply embedded in the seabed, to avoid as much as possible sudden heavy loads on the pendant string from the rise and fall of the vessel in the seaway.

If it is necessary to deck an anchor, it should be secured on deck so that it cannot move due to the movement of the vessel.

Multiple Pendants

Care should be taken when stowing multiple pendants on the winch drum to avoid fouled pendants when the wire is unwound. If 'bow' type shackles are used they should be placed so that the pin is toward the winch as this reduces the possibility of fouling behind the pin when the wire is unwound under load.

Length of Pendant from Rig

The length of pendant that is passed to the vessel from the installation should be sufficient to allow the vessel room to manoeuvre to keep the pendant slack while it is being connected to the work-wire/pendant by the deck crew.

Anchor Deployment

The anchor handling vessel should be held in line with the anchor cable while the anchor is deployed and until the buoy is in the water so that the pendant is laid out in a straight line away from the anchor, reducing as much as possible the hazards associated with fouled anchors.

The installation should tension the cable as soon as possible after the anchor is on the bottom to 'set' the anchor below the seabed and thus avoid fouled anchors.

Buoy Deployment

Buoys should be deployed from as close to the stern of the vessel as possible to avoid an uncontrolled and damaging progression along the length of the deck.

Passing Pendant to Rig

Ensure that the pendant is not released from the securing device on deck until the crane has taken the weight as this can lead to unacceptable shock loads on the crane.

Clearing Fouled Anchors

Crew members should be aware that coils of pendant wire fouling an anchor may move sharply as they are cleared. Clearing should be accomplished as much as possible using tuggers and other mechanical means.

Pendant wires that have been cleared from a fouled
