ABSTRACT:
An anchoring system for semisubmersible drill rigs is described which includes a wire rope-chain cable anchor line and in which system components co-operate to convey the junction of the wire rope and chain cable smoothly over a fairlead sheave. The connector joining the anchor line has a narrow end in which the rope is rigidly retained, a large end at which a chain end link is pivotally retained, and a radially symmetric, generally concave surface extending between the two connector ends. The outer surface of the connector is shaped to seat against the central hub of the fairlead sheave in a predetermined orientation in which a limited fixed bend angle is formed between the connector and the wire rope. The geometry of the connector naturally biases the connector to seat against the central hub of the fairlead sheave in the predeterminted orientation during hauling in of the anchor line. A collar fitted about the penultimate chain link displaces the large connector end from the sheave during paying out of the anchor line until the outer connector surface can be drawn by the wire rope into engagement with the sheave. Wire rope bending is accordingly minimized without significantly enlarging or altering the size of the fairlead sheave.
