The invention provides a novel five-stand-column semi-submersible type wind power foundation and a mooring system thereof. The novel five-stand-column semi-submersible type wind power foundation comprises an X-shaped buoyancy tank, side stand columns are arranged at the four ends of the X-shaped buoyancy tank, a center stand column is arranged in the center of the X-shaped buoyancy tank, and the four side stand columns are distributed in a central symmetry mode relative to the center stand column; a tower drum is arranged on the center stand column, and a wind turbine generator set is arranged at the top end of the tower drum and converts wind energy into electric energy. An outer platform is further arranged on the peripheral face of the joint of the center stand column and the tower drum. The number of side stand columns providing stability in the prior art is increased from three to four, and the waterplane inertia moment is increased by nearly 50% under the condition that the waterplane area is not changed; the stress of the structure is completely transferred to the X-shaped floating box, so that the gravity center of the structure is lowered; meanwhile, communication of the side stand columns and the middle stand columns is achieved through the design that the deck channel and the outer platform are staggered in elevation, and follow-up operation and maintenance are guaranteed; and finally, '8 * 1 'distributed mooring is put forward to replace '4 * 2' symmetrical mooring, and mooring constraint optimization is guaranteed.

    本发明提供一种新型五立柱半潜式风电基础及其系泊系统,包括X型浮箱,X型浮箱的四个端部均设置有侧立柱,X型浮箱的中心处设置有中心立柱,四个侧立柱关于中心立柱呈中心对称分布;中心立柱上设置有塔筒,塔筒的顶端设置有风电机组,风电机组将风能转化为电能;中心立柱与塔筒交接处的外周面上还设置有外平台。本发明将现有技术中提供稳性的侧立柱由三个增至四个,在水线面面积不变的情况下提高水线面惯性矩将近50%;并将结构受力全部转移至X型浮箱,降低结构重心;同时通过甲板通道和外平台高程错开的设计实现侧立柱与中间立柱的连通,保证后续运维;最后提出“8x1”分散式系泊代替“4x2”对称式系泊,保证系泊约束最优化。
