Offshore self-elevating ocean engineering drilling platform
The invention relates to the technical field of ocean engineering, in particular to an offshore self-elevating ocean engineering drilling platform. The drilling platform comprises a drilling platform body, wherein the drilling platform body comprises a platform supporting plate and buoyancy tanks arranged on the two sides of the bottom of the platform supporting plate, connecting rings fixedly connected with the buoyancy tanks in an inserted mode are arranged at the bottoms of stand columns, the stand columns are arranged between the two sides of the buoyancy tanks and the platform supporting plate, a self-elevating floating increasing device is arranged at the position, located among the four stand columns, of the top of the buoyancy tanks. According to the drilling platform, the contact area between the bottom of the platform supporting plate and seawater is increased through overturning of a floating-increasing plate, floating-increasing treatment of the platform supporting plate is achieved, the larger the overturning angle of the floating-increasing plate is under the condition that the floating-increasing plate is not horizontal, the larger the increased area is, the larger the increased buoyancy is, and the problem that when the height of the platform supporting plate is decreased, the bottom buoyancy of the platform supporting plate cannot be increased is solved.
本发明涉及海洋工程技术领域，具体地说，涉及一种近海用自升式海洋工程钻井平台。其包括钻孔平台本体，所述钻孔平台本体包括平台支板和设置在平台支板底部两侧的浮箱，另外立柱底部设有与浮箱插接固定的连接环，浮箱的两侧和平台支板之间设有立柱，所述浮箱的顶部位于四个立柱之间的位置设有自升式增浮装置。本发明中通过增浮板的翻转增大平台支板底部与海水的接触面积，从而实现了对平台支板的增浮处理，且增浮板在没有水平的情况下翻转的角度越大增加的面积也就越大，增加的浮力也就越大，进而解决了当平台支板高度下降时，无法增加平台支板底部浮力的问题。
