ANCHORING SYSTEM OF SEMI-SUBMERSIBLE MARINE STRUCTURE

摘要

The present invention relates to an anchoring system of a semi-submersible offshore structure and, more specifically, to a semi-submersible offshore structure which maximizes the use of the arrangement space inside a column, improves stability, and secures reserve buoyancy by preparing a chain locker on the outer side of the column of the semi-submersible offshore structure. The anchoring system installed in the semi-submersible offshore structure, which has a pontoon, a deck box installed on the top of the pontoon, and multiple columns connecting the pontoon and the deck box, comprises: a chain locker which is installed on the outer side of the column; an anchor chain which is drawn into/from the chain locker; an anchor which is connected to the anchor chain to be fixed to a seabed or the pontoon; and a windlass which is installed on the top of the column to intermediate the anchor chain.
