The invention relates to an integrated disassembling and assembling system and method for a large offshore structure, and belongs to the technical field of ocean engineering. The system comprises a semi-submersible ship I, a semi-submersible ship II, a lifting arm I, a lifting arm II and an offshore structure, the support I and the support II of the lifting arm I are installed on the semi-submersible ship I through bolts, and the support I and the support II of the lifting arm II are installed on the semi-submersible ship II through bolts; a plurality of lifting arms I are arranged on the semi-submersible ship I in parallel, and a plurality of lifting arms II are arranged on the semi-submersible ship II in parallel; the lifting arm I and the lifting arm II are provided with a lifting system with a three-way movement compensation function, and the lifting system is provided with locking mechanisms; and before lifting, the locking mechanisms of the lifting arm I and the lifting arm II act, and the lifting arm I and the lifting arm II are locked in the front-back direction and the left-right direction, and the lifting mechanisms act at the same time to lift the offshore structure. Lifting operation is completed through rapid load discharging of the ship body and rapid lifting of the lifting arm hydraulic system, so that the whole disassembling process is short in consumed time and high in efficiency.

    本发明涉及一种大型海上结构物一体化拆装系统及拆装方法,属于海洋工程技术领域。本发明包括半潜船Ⅰ、半潜船Ⅱ、举升臂Ⅰ、举升臂Ⅱ和海上结构物,举升臂Ⅰ的支座Ⅰ及支座Ⅱ,通过螺栓安装于半潜船Ⅰ上,举升臂Ⅱ的支座Ⅰ及支座Ⅱ,通过螺栓安装于半潜船Ⅱ上;半潜船Ⅰ上平行排列若干条举升臂Ⅰ,半潜船Ⅱ上平行排列若干条举升臂Ⅱ;举升臂Ⅰ与举升臂Ⅱ带有三向移动补偿功能的举升系统,举升系统带有锁紧机构;抬升前,举升臂Ⅰ与举升臂Ⅱ锁紧机构动作,举升臂Ⅰ与举升臂Ⅱ前后、左右两方向锁紧;举升机构同时动作,将海上结构物抬起。本发明通过船体的快速排载及举升臂液压系统的快速举升共同完成举升作业,使整个拆解过程用时短,效率高。
