The invention discloses a novel semi-submersible platform and a mounting method thereof. The novel semi-submersible platform comprises a platform hull and a top tensioning type steel vertical pipe; the top tensioning type steel vertical pipe comprises an upper-end oil extraction vertical pipe and a lower-end oil extraction vertical pipe; a reclaimed water buoy is connected between the upper-end oil extraction vertical pipe and the lower-end oil extraction vertical pipe; a truss is arranged on the reclaimed water buoy, a vertical pipe guide frame is arranged at the upper end of the truss, the vertical pipe guide frame is movably connected with a main deck of the platform hull through a spring support, and the spring support is fixedly connected with a main deck; the top of the upper-end oilextraction vertical pipe is matched with the vertical pipe guide frame; a Christmas tree is arranged on a vertical pipe fixing frame; and the Christmas tree is connected with a crude oil treatment device arranged on the main deck of the platform hull. The novel semi-submersible platform has independent buoyancy, and the vertical load of the novel semi-submersible platform on the platform is reduced; and decoupling of heaving motion and longitudinal and transverse shaking motion of the top of the vertical pipe and the platform hull is achieved, so motion of the platform is not directly transmitted to the vertical pipe, and the dry tree oil extraction function can be achieved.
本发明公开了一种新型半潜式平台及其安装方法。所述新型半潜式平台包括平台船体和顶张紧型钢制立管;顶张紧型钢制立管包括上端采油立管和下端采油立管;上端采油立管和下端采油立管之间连接中水浮筒;中水浮筒上设置桁架,桁架的上端设置立管导向架,立管导向架通过弹簧支座与平台船体的主甲板活动连接,且弹簧支座与主甲板固定连接;上端采油立管的顶部与立管导向架配合;立管固定架上设有采油树;采油树与设于平台船体的主甲板上的原油处理装置连接。本发明新型半潜式平台具有独立的浮力,降低了其对平台的垂向载荷;实现了立管顶部与平台船体升沉运动和纵横摇运动的解耦,使得平台的运动不直接传递到立管上,又可以实现干树采油功能。
