An arcuate fairlead for mooring lines has an arcuate row of grooved line-engaging shoes of plastic material which shoes can be removed and replacement shoes can be installed without disassembling the mooring line from the fairlead. The fairlead is of generally triangular shape supported by trunnion and bearing means at its upper tip and adjacent to its apex enabling the fairlead to swing about an upright axis for self-alignment with a stretch of mooring cable beyond the lower tip of the fairlead.

Self-aligning quadrant fairlead

This system is for offshore operations and includes a boat having a towing and an anchor handling winch are respectively disposed on the boat deck so as to rotate about horizontal axis. In connection with an offshore rig using chain or cable attached to the anchor, the anchor winch on the boat is used to spool the pendant cable which is attached to the anchor end of the chain until the underwater buoy is brought on the boat deck. The towing cable on the other towing winch is then attached to the buoy cable to suspend the chain and anchor in the water while the pendant cable is disconnected from the buoy cable. The disconnected end of the pendant cable is then connected to a vertical spool on the boat deck and spooled onto the vertical spool from the horizontal anchor handling winch while the chain or cable is being retrieved by an apparatus on the rig.
