Mooring safety advisory
“There have recently been some cases of mooring failures due to the top ropes being damaged by twisting against the lay of the rope. Mooring systems employing Fergie buoys or similar (where the top rope passes through the buoy) with three strand rope appear to be more prone to this problem...
... Mooring owners using Fergie buoys or similar are urgently advised to check their top ropes for any signs of twisting or hockling (where the rope eventually folds back on itself) as it will weaken the rope and may even allow any splices to slip free. Multiplait rope is preferable for use with these types of buoys as the splices will not unlay when twisted...”
