The invention discloses a semi-submersible drilling platform with a drilling frame arranged on a main deck right above a stand column. The platform comprises a buoy for providing buoyancy, a stand column for connecting the buoy and a deck box, a deck box for providing an operation space, a drilling frame arranged on the side surface, and a living area arranged in an L shape with the diagonal position of the drilling frame, wherein a drilling riser penetrates through a moon pool arranged between the stand column and the buoy, and the drilling riser or a production riser and the like are protected from being collided by floating ice through the stand column and a buoy structure. The drilling frame is arranged on the main deck above one stand column at the four corners of the platform, so the drilling stand pipe can penetrate through the stand columns and the buoys below the drilling stand pipe and then enter seawater, the stand column and buoy structures are used for protecting an original exposed stand pipe system, collision of sea ice on the water surface is avoided, the vertical pipe system is protected; and operation performance of the whole platform is improved.
本发明公开了一种钻井架布置在立柱正上方主甲板上的半潜式钻井平台,该平台包括提供浮力的浮筒,连接浮筒和甲板盒的立柱,提供操作空间的甲板盒,侧面布置的钻井架,与钻井架对角位置成L型布置的生活区,钻井立管穿过立柱和浮筒中间设置的月池,通过立柱和浮筒结构保护钻井或生产立管等不被浮冰碰撞。本发明通过将钻井架布置在平台四个角的一个立柱上方的主甲板上,使得钻井立管可以穿过其下方的立柱和浮筒后进入海水中,利用立柱和浮筒结构对原有裸露的立管系统进行保护,避免了水面部分海冰的碰撞,从而对立管系统提供了保护。并提升了整个平台的作业性能。
