Abstract: An offshore structure is separated into an upper structure and a lower structure. Part or whole of the lower structure is kept in an upright standing state in water. The upper structure is moved to above the lower structure kept in the upright standing state. A uniting step includes one or both of raising the lower structure to arrange the lower structure on a lower side of the upper structure and lowering the upper structure to arrange the upper structure on an upper side of the lower structure by submerging part of a carrier vessel on which the upper structure is mounted while being held by a pair of arm-shaped structures of the carrier vessel and integrating the lower structure with the upper structure. In this way, an offshore structure is moored safely at an offshore installation site without using a crane vessel.

Abstract: A system includes mooring lines arranged respectively in three to eight directions, and at least one of a plurality of offshore structures included in the offshore structure group is moored by locking the mooring lines in the respective directions with separate mooring bases, and at least one of the mooring bases locks the mooring lines which are connected respectively to three to eight of the offshore structures in the offshore structure group. With this configuration, even when part of the mooring lines mooring the offshore structures is broken or the mooring function of the mooring bases is lost, although the offshore structure moves, the offshore structure is kept being moored by the remaining mooring-line group, so that the offshore structure can be prevented from colliding with another offshore structure.
