The invention relates to the technical field of ocean engineering. The invention discloses an offshore building unsealing operation platform. The system comprises a deck, a tower, a plugging operationmodule, a pile winding crane, a first lifting machine and a second lifting machine, the outer contour of the deck is rhombic; the tower and the pile winding crane are oppositely arranged at the acuteangle end of the deck; the first lifting machine and the second lifting machine are oppositely arranged at the obtuse angle end of the deck; the plugging operation module is detachably arranged on the deck; the acute angle end of the deck can enter a narrow position to be fixed; the construction platform is simple in structure and high in flexibility, the pile winding crane achieves dismantling operation of the to-be-dismantled platform, the detachable plugging operation module achieves plugging operation of a wellhead, after plugging is completed, the plugging operation module can be removed, a deck serves as an area where the dismantling module can be stored, and the space utilization rate and the operation efficiency of the operation platform are improved. The invention further provides an offshore building unsealing method.

    本发明涉及海洋工程技术领域,公开了一种海上建筑拆封作业平台,包括甲板、塔楼、封堵作业模块、绕桩吊机、第一起吊机以及第二起吊机,甲板的外轮廓呈菱形,塔楼和绕桩吊机相对设置于甲板的锐角端,第一起吊机和第二起吊机相对设置于甲板的钝角端,封堵作业模块可拆卸设于甲板上,利用甲板的锐角端可进入较狭小的位置进行固定,灵活性高,绕桩吊机实现待拆解平台的拆除作业,可拆卸的封堵作业模块实现井口的封堵作业,当封堵完成后,可将封堵作业模块进行移除,使得甲板作为可以存放拆除模块的区域,提高了该作业平台空间利用率以及作业效率。本发明还提供一种海上建筑拆封方法。
