SYSTEM FOR MOORING OFFSHORE STRUCTURE GROUP AND METHOD FOR MOORING OFFSHORE STRUCTURE GROUP

摘要

A system includes mooring lines 20 arranged respectively in three to eight directions, and at least one of a plurality of offshore structures 10 included in the offshore structure group is moored by locking the mooring lines 20 in the respective directions with separate mooring bases 30, and at least one of the mooring bases 30 locks the mooring lines 20 which are connected respectively to three to eight of the offshore structures 10 in the offshore structure group. With this configuration, even when part of the mooring lines 20 mooring the offshore structures 10 is broken or the mooring function of the mooring bases 30 is lost, although the offshore structure 10 moves, the offshore structure 10 is kept being moored by the remaining mooring-line group, so that the offshore structure 10 can be prevented from colliding with another offshore structure 10, thus making it possible to moor the offshore structure 10 at the offshore installation site safely without excessively increasing the strength of the mooring lines 20 in the mooring directions.
