INVENTION: COMBINATION ANCHOR LINE ADAPTED FOR PASSAGE OVER FAIRLEAD SHEAVES AND CHAIN WHEELS INVENTOR: MARTIN MURRAY AND GEOFFREY TAYLOR ABSTRACT OF THE DISCLOSURE In an anchoring system suitable for a semisubmersible drill platform or other ocean-going vessel, in which the anchor line consists of a length of wire rope and a length of chain cable, the anchor line is smoothly conveyed over system fairlead sheaves and chain wheels. The junction between wire rope and chain cable includes a conventional socketed rope connector which permits rope pivotting at the rope-cable junction. One or more collars are attached to links of the chain cable, and carry a multiplicity of outwardly directed projection. These projections are so arranged as to engage the rims of the flanges of the anchoring system fairlead sheaves and chain wheels, suspending the junction form the flange rims during transition of the junction over the sheave-like structures, and permitting the socketed rope connector to pivot freely. this arrangement eliminates excessive rope bending, allows use of a pocketed fairleaders, and permits the construction of a practical non-disconnect mooring system.
