OFFSHORE MOORING LINES

 

 

The offshore mooring line or anchor rode is the means of connecting the anchor on the seafloor to a large ship or a floating structure at the surface. The mooring line is also called mooring wire, anchor rode, mooring chain, mooring rope, mooring hawser or mooring warp. The mooring line consists of rope or wire rope and chain and a variety of connectors.

There is a large variety of solutions available. Here we focus on giving an overview of mooring line solutions for MODUs (Mobile Offshore Drilling Units) and FPSs (Floating Production Systems).

The mooring line can consist of chain or/and metal wire rope or/and synthetic fiber rope.

The construction(s) and material(s) are determined for the performance of the mooring line. The mooring line is a part of a mooring system. The other components of the mooring system are the anchor(s) and the connectors. The mooring system is used for station keeping/mooring of a ship or floating offshore structure in shallow water or deep water or ultra-deep water.

The mooring system must be designed to withstand the environmental forces from wind, waves and currents from any direction and that the horizontal excursions of the vessel or floating structure are small to avoid damage to the sub sea equipment or risers. The mooring system is a crucial element for any floating offshore structure.
