The invention provides at least three bottom-supported bases of a semi-submersible platform and an installation technology thereof.The bottom-supported bases of the semi-submersible platform comprise middle columns, top decks connected to the tops of the middle columns and hollow suction piles connected with the bottoms of the middle columns, and the bottoms of the hollow suction piles are open; wherein the interior of the middle column body is divided into a plurality of soft cabins, the side wall of each soft cabin is provided with a sea opening and a ventilation opening, and the suction piles are communicated with a water pumping device on the transport ship. The bottom-sitting base of the semi-submersible platform is simple in structure and convenient to sink to the bottom, the stand column mounting surface of the semi-submersible platform is relatively smooth through the bottom-sitting base, and the problem that the semi-submersible platform is unstable in mounting due to fluctuation of a seabed or stones on the seabed is solved.
本发明提供一种半潜浮式平台的坐底基座及其安装工艺,其中,该种半潜浮式平台的坐底基座,至少设置有三个,坐底基座包括:中部柱体,连接在中部柱体顶部的顶部甲板,以及与中部柱体底部连接、且底部敞口的中空吸力桩;其中,中部柱体内分隔有多个软舱,各软舱侧壁上均开设有通海口和通气口,吸力桩与运输船上的抽水装置连通。本发明半潜浮式平台的坐底基座,结构简单,沉底方便,通过坐底基座使半潜浮式平台的立柱安装面相对平整,解决了因海床起伏、或海床上石块导致的半潜浮式平台安装不稳定的问题。
