FOUNDATION STRUCTURE FOR OFFSHORE WIND POWER GENERATION DEVICE
To provide a foundation structure for an offshore wind power generation device that allows workers and equipment to safely and quickly come and go between a work boat and an offshore wind power generation device, and prevents a berth period of the work boat from being unnecessarily extended.SOLUTION: A foundation structure 100 of an offshore wind power generation device 200 including a tower portion 220 and a wind turbine portion includes a cylindrical main body 10 that directly or indirectly supports the tower portion 220. The cylindrical main body 10 has an upper end 11 located at or near the sea surface 900, and a lower end 12 supported directly or indirectly on the sea bed 910. An enlarged diameter portion 20 extending in the circumferential direction on an outer circumferential surface of the cylindrical main body 10 is provided at a position equal to or higher than the height h1 of one half of the cylindrical main body 10 in the vertical direction. The enlarged diameter portion 20 is configured such that the thickness measured in the vertical direction increases from a distal end portion 22 furthest from the outer circumferential surface of the cylindrical main body 10 toward a foundation end side that is the outer circumferential surface side of the cylindrical main body 10.SELECTED DRAWING: Figure 1
【課題】作業船と洋上風力発電装置とにおいて作業員および機材が安全かつ速やかに行き来することを可能とするとともに、無用に作業船の停泊期間が延びることを防止することが可能な洋上風力発電装置の基礎構造を提供する。【解決手段】タワー部２２０と風車部とを備える洋上風力発電装置２００の基礎構造１００は、タワー部２２０を直接または間接に支持する筒状本体１０を備え、筒状本体１０は、上端１１が海面９００またはその近傍に位置するとともに下端１２が海底９１０に直接または間接に支持され、筒状本体１０の上下方向２分の１の高さｈ１以上の位置において、筒状本体１０の外周面を周方向に延在する拡径部２０が設けられており、拡径部２０は、筒状本体１０の外周面から最も離れた先端部２２から、筒状本体１０の外周面側である基端側に向けて上下方向において測定される厚みが増大するよう構成される。【選択図】図１
