The invention discloses a semi-submersible drilling auxiliary platform round-sky and square-earth crane base structure, which relates to the technical field of ocean engineering, and comprises a crane base which is arranged on an ocean platform deck and is of a cylindrical structure; the base reinforcing structure is arranged on the ocean platform deck, connected with the crane base, of a square framework structure and comprises a base transition section and a base lower section, one end of the base lower section is connected with the base transition section, and the other end of the base lower section is connected with the ocean platform deck. According to the round-sky and square-earth crane base structure of the semi-submersible type drilling auxiliary platform, the base reinforcing structure and the crane base are connected to form a whole, the strength requirement is met, compared with an existing cylinder structure, the construction cost is saved through the directional framework structures of the base transition section and the base lower section, the structural weight is effectively reduced, and the construction cost is reduced. And the universality of the crane base is ensured. The ocean platform deck and the lower section of the base are welded, so that the base and the platform form a whole, sudden stress change of the base is avoided, and the load requirement of the crane base is met.

    本发明公开了半潜式钻井辅助平台天圆地方吊机基座结构,涉及海洋工程技术领域,包括吊机基座,设置于海洋平台甲板上,呈圆柱形结构;基座加强结构,设置于海洋平台甲板上,与吊机基座连接,呈方型骨架结构,包括基座过渡段和基座下段,基座下段一端与基座过渡段连接,另一端与海洋平台甲板连接。根据本发明的半潜式钻井辅助平台天圆地方吊机基座结构,基座加强结构与吊机基座连接形成整体,满足强度要求,基座过渡段和基座下段的方向骨架结构相比于现有的圆筒结构节约建造成本,有效降低结构重量,并且保证了吊机基座的通用性。海洋平台甲板与基座下段的焊接使基座与平台形成整体,避免基座应力突变,满足吊机基座的载荷要求。
