METHOD FOR ASSEMBLING OFFSHORE STRUCTURE

摘要

PURPOSE: A method for assembling offshore structure is provided to reduce costs and time for assembling offshore structure and to improve productivity by rapidly assembling the offshore structure. CONSTITUTION: A method for assembling offshore structure is as follows. A spar body part(130) in which multiple supporting pillars(120) are coupled is floated. In order that a part of the supporting pillars is projected from seawater level, the spar body part is vertically taken in the seawater and is fixed in multiple cables fixed at the seabed. A spar top plate(110) on which a boring facility is loaded on a barge to move to the sea. The barge is put between the multiple supporting pillars. The barge, loading the spar top plate, is taken in the water to mount the spar top plate, on which the boring facility is installed, on the multiple supporting pillars. The spar top plate and the multiple supporting pillars are coupled.
