To efficiently build a spar-type offshore wind power generation facility by assembling a top unit structure of the facility at once in construction and to enable work to be carried out stably by suppressing oscillation especially when heavy matter is hung by a semi-sub type crane used in construction.SOLUTION: A building method for a spar-type offshore wind power generation facility 1 includes: a first step for carrying out assembly of a top unit structure 12 of an offshore wind power generation facility composed of a tower 6, a nacelle 8, and a blade 9 on a frame 13 for assembly in a sea area selected as a calm area with comparatively mild waves; a second step for lifting the top unit structure 12 assembled on the frame 13 for assembly at once by a semi-sub type crane 2 provided with a mobile type counter weight device 3 on the deck surface to transport the top unit structure to a building site for the offshore wind power generation facility 1; a third step for retaining a floating body 4 offshore in a standing state; and a fourth step for completing the offshore wind power generation facility 1 by coupling the top unit structure 12 to the top unit of the floating body 4 in a lifted state by the semi-sub type crane 2.SELECTED DRAWING: Figure 17

    【課題】スパー型洋上風力発電設備の上部構造体を一括施工で組立てすることにより建造の効率化を図るとともに、施工に用いるセミサブ型クレーンは特に重量物を吊り下げた際の動揺を抑えて安定的に作業を行い得るようにする。【解決手段】比較的波の穏やかな静穏域として選定された海域において、組立用架台13上でタワー6、ナセル8及びブレード9からなる洋上風力発電設備の上部構造体12の組立てを行う第1ステップと、前記組立用架台13上で組み立てた前記上部構造体12を、デッキ面に移動式カウンターウエイト装置3を設備したセミサブ型クレーン2によって一括で吊り上げて洋上風力発電設備1の建造場所まで運搬する第2ステップと、浮体4を洋上に起立状態で保持する第3ステップと、前記セミサブ型クレーン2によって前記上部構造体12を吊り上げた状態のまま前記浮体4の上部に連結して洋上風力発電設備1を完成させる第4ステップとからなる。【選択図】図17
