Over the years, mooring systems have evolved to meet the industry's demands for increased station-keeping capability and reliability. Mooring components such as chain, ropes, and connectors are being designed larger and constructed using new materials. In deeper water and harsher conditions, turret mooring, disconnectable and thruster-assisted systems are improving station-keeping capability. But as these systems expand in complexity, a wider range of operational considerations must be taken into account New components require extensive design verification and will in some cases present installation and operational challenges. Another issue that needs to be addressed is how best to inspect and maintain the equipment. In addition, there is uncertainty about the corrosion characteristics of some of the new components, with a lack of in-service data available to determine their long-term performance.
