Abstract
A system and method for configuring and supporting mooring lines deployed on offshore structures, e.g. Spar-type platform, are provided with recessed portions that are located around the splash/ice zones for 'cutting' through waves. An offshore structure may be provided with a chain tensioning mechanism that applies a desired tension to a hull chain and mooring line during mooring. Upon mooring the offshore structure, a chain lock mechanism maintains the tension in the hull chain and mooring line, while the chain tensioning mechanism releases a portion of the hull chain which is to be stored in a chain housing which is fully submerged underwater. This way, the recessed portions of the offshore structure around the splash/ice zones would be substantially free of the hull chains. Additionally, a disconnect mechanism may be provided to allow quick and safe disconnection of the offshore structure from the mooring position.
