ends of the swage and the condition of the thimble. Wires with badly crushed or distorted thimbles should not be used.

Sockets and eyes must be of an appropriate size to enable easy connection when used with the correct size shackle. The use of two shackles between pendants or work wires is discouraged due to the hazards created when winding excess gear onto work drums.

Current test certificates (preferably proof load or ultrasonic/magnetic particle test as a minimum) must be available for sockets (with individual serial numbers rather than the previously used batch numbers) prior to use. Sockets should be properly fixed to the wire by an experienced person using correct procedures and materials that are approved for the purpose.

Shackles

Only shackles of sufficient SWL must be used when handling anchors, taking into account that the anchor may be deeply embedded in the seabed thus increasing the load to which the equipment is subjected.

Link type shackles ('Baldt' or 'Kenter' style) or hinge links are preferred for use between pennants or where multiple shackles must be wound onto the winch drum. The risk of fouling the pennant as it is unwound under load is much reduced when these links are used.

If 'Bow' type shackles are used for winding onto winch drums they should be placed such that the pin is toward the winch as this also reduces the incidence of fouling of the wire when it is unwound under load.

Roller Fairleads

The use of roller fairleads mounted on the deck or crash barriers of vessels should be carefully monitored. Inspection and maintenance must be performed regularly as any uplift by external forces, such as a tugger wire, may dislodge roller fairleads from their seating. Careful reassembly of these leads after maintenance is important.

Personnel should never stand inside the bight of wire around a roller fairlead.

Hydraulic or Mechanical Stoppers

These usually come in the form of 'Shark Jaws' (or Triplex gear), 'Ulstein Tong', and 'Karm Fork' designs or other similar proprietary mechanical/hydraulic securing devices. These devices should be used strictly in accordance with the manufacturer's instructions.

'Ulstein Tongs', 'Karm Forks' and other types that use removable jaws for different applications are dangerous if the wrong jaws are used. For this reason it is important that the correct jaws be used for chain and wire applications.

Ensure the device is 'Locked' either mechanically (by pins or bars) or hydraulically before crew members commence work on the connection. Visual inspection must be done on each occasion with the hydraulic locking type to ensure that the arms have reached the over-centre point where locking is effective.
