Arrangements for recovering an anchor mooring line with or without its associated anchor

摘要

An anchor mooring line is recovered from its associated suction anchor which is to be abandoned by means of an arrangement comprising an activation chain 18 attached to the head of a taper pin 10 passing through two journal blocks 5 and 6. Application of suitable tension to the chain 18 shears a shearpin 11 thus allowing the mooring line 1 with associated shackle 3 and rotating padeye unit 2 to be recovered. Embodiments are also disclosed (Figs 5-13) for recovering an anchor mooring line together with its associated suction anchor by application of vertical tension to the anchor via a winch line from an anchor handling tug. The suction anchor may comprise a single part (Figs 5-8) or a plurality of interconnected parts (Figs 9-13).
