PROBLEM TO BE SOLVED: To moor an offshore structure at an offshore installation location without using a floating crane in a construction method of a spar-type offshore structure equipped with a wind-force power generator etc. or the like.SOLUTION: A construction method of an offshore structure includes: a manufacturing step where an offshore structure 10 is manufactured while being divided into an upper structure 11 and a lower structure 12; an underwater maintaining step where a part or an entire part of the lower structure 12 is maintained in an upright state in water; a moving step where the upper structure 11 is moved to an area above the lower structure 12 maintained in the upright state; an integration step where a lifting step, in which the lower structure 12 is lifted to be disposed at the lower side of the upper structure 11, is conducted; and a joint step where the lower structure 12 is integrated with the upper structure 11.SELECTED DRAWING: Figure 12

    【課題】風力発電装置等を搭載したスパー型等の洋上構造物の施工方法において、クレーン船を使用することなく、安全に洋上設置場所に係留する。【解決手段】洋上構造物10を上部構造物11と下部構造物12に分割して製造する製造工程と、下部構造物12の一部又は全部を水中に直立状態に維持する水中維持工程と、この直立状態に維持した下部構造物12の上方部位に、上部構造物11を移動する移動工程と、下部構造物12を上昇させて、上部構造物11の下側に配置する上昇工程を行う合体工程と、下部構造物12を上部構造物11に一体化する接合工程とを含んで洋上構造物の施工方法を構成する。【選択図】図12
