The invention an offshore wind power double-body installation platform and a cylindrical foundation installation method. The offshore wind power double-body installation platform is used for installing a cylindrical foundation and comprises a first installation platform body and a second installation platform body which are symmetrically arranged in the left-right opposite direction and a plurality of sliding devices, wherein the cylindrical foundation is embedded between the first installation platform body and the second installation platform body and connected with the first installation platform body and the second installation platform body into a whole, buoyancy tanks are arranged on the outer side wall, the front side wall and the rear side wall of the first installation platform body and the outer side wall, the front side wall and the rear side wall of the second installation platform body, a positioning pile hole is formed in each buoyancy tank, a positioning pile is arranged in each positioning pile hole in a penetrating mode, and the positioning piles and the corresponding buoyancy tanks can relatively slide up and down; and the plurality of sliding devices are in one-to-one correspondence with the positioning piles, and the first installation platform body, the cylindrical foundation and the second installation platform body which are connected into a whole can slide downwards along the positioning piles under the action of the sliding devices. The problem that foundations with different cylinder diameters cannot be stably installed and constructed is solved, and on the basis that large-scale transportation of the cylindrical foundations is achieved, the installation platform is flexible, stable in transportation and convenient to maintain and replace.

本发明公开了一种海上风电双体安装平台及筒型基础安装方法，安装平台用于安装筒型基础，包括左右相向对称布置的第一安装平台和第二安装平台，筒型基础嵌入设置在两者之间、并与两者连接为整体，第一安装平台的外侧壁、前后两侧壁和第二安装平台的外侧壁、前后两侧壁上均设置浮箱，每个浮箱上开设有定位桩孔，每个定位桩孔内穿设有定位桩，定位桩与对应的浮箱之间能相对上下滑移；若干组与定位桩一一对应的滑移装置，连接为整体的第一安装平台、筒型基础和第二安装平台能在滑移装置的作用下沿定位桩向下滑移。本发明解决了不同筒径基础无法平稳安装施工的问题，在实现筒型基础规模化输运的基础上，既灵活机动，又输运稳定，且便于维修和更换。
