The invention relates to a buoyancy eccentric semi-submersible floating type fan foundation suitable for a large megawatt unit, which comprises a semi-submersible floating type fan foundation, and the semi-submersible floating type fan foundation comprises three vertical columns, three horizontal buoyancy tanks, three groups of supporting rods and two heaving plates. The three vertical stand columns comprise a fan stand column and two non-fan stand columns, the fan stand column comprises a stand column bottom thickened section, a second central stand column and a second stand column water plane thickened section, and each non-fan stand column comprises a first central stand column and a first stand column water plane thickened section. The thickened section at the bottom of the fan stand column or the thickened stand column provides large buoyancy to be directly balanced with most gravity of the fan unit, the weight and the ballast capacity in the non-fan stand column and the horizontal buoyancy tank are greatly reduced, and meanwhile the bending moment borne by the horizontal buoyancy tank and the supporting rod is reduced. And the steel consumption and the construction difficulty of non-fan stand columns, horizontal buoyancy tanks and supporting rods are reduced.

    本发明涉及一种适用于大兆瓦机组的浮力偏心式半潜漂浮式风机基础,包括半潜漂浮式风机基础,半潜漂浮式风机基础包括三个垂直立柱、三个水平浮箱、三组撑杆、两个垂荡板。三个所述垂直立柱包含一个风机立柱和两个非风机立柱,风机立柱包括立柱底部加粗段、第二中心立柱和第二立柱水线面加粗段,非风机立柱包括第一中心立柱和第一立柱水线面加粗段。风机立柱的立柱底部加粗段或加粗立柱提供较大的浮力直接与风机机组的大部分重力平衡,大大降低非风机立柱与水平浮箱内的重量与压载量,同时减小水平浮箱与撑杆所受弯矩大小,减少非风机立柱、水平浮箱、撑杆的用钢量与建造难度。
