Loading line for submarine cables - has various designs of holding line with loose connections to submarine cable

摘要

The load line is intended to retain the cable in position on the sea bed to prevent damage and also to lift the cable if required. The line is a high strength, flexible wire that is loosely connected to the cable so that while under water it exerts no tension or compression. The flexible wire can be a group of several parallel strands or several cables connected together by a waterproof adhesive. The holders can be rings, tubes or hoses that are not affected if the wire or bundle of wires is twisted. An alternative design uses a chain or a series of rigid rods connected together to from a chain. Finally the line can consist of a series of waterproof heavy blocks.
