Shark jaws (AHTS)
Providing increased safety and functionality. Designed to guide wire / chain safely, without the presence of crew and also work as a securing mechanism.
The shark jaw is normally used in conjunction with towing pins and centring devices. All three items retract flush with the deck when not in use. Towing pins control and restrict transverse movement of the towline. They work as the securing mechanism required by NMD when there is a load hanging from the shark jaw. Operation of towing pins, centring device and shark jaw is remote controlled from the bridge reducing risk to deck crew by avoiding work on unsecured heavily loaded chains or wires. A portable remote control is available for use during service and maintenance work.
