摘要

PROBLEM TO BE SOLVED: To reduce construction cost and power generation cost by conducting construction work in a short time without being influenced by change in weather conditions and ocean conditions.;SOLUTION: In the substructure for the ocean wind power generation device, a footing 1 is installed on a submarine ground 35, and a windmill is mounted on the footing 1 through a windmill tower 40. A work stage 15 is mounted on an upper part of the footing 1 in such a manner of being detachable, and rotatable around a center part of the footing 1. The work stage 15 is provided with a working platform 16 oppositely arranged on the upper part of the footing 1, a support means 18 rotatably supporting the working platform 16 on the footing 1, and a driving means 25 for rotating and driving the working platform 16. Various kinds of work for fixing the footing 1 on the ground 35 can be carried out from the working platform 16, and therefore, the construction work can be performed in a short time without being influenced by the change of the weather conditions and the ocean conditions.;COPYRIGHT: (C)2007,JPO&INPIT
