The invention discloses an offshore platform dismantling method. The method comprises that: a first lifting ship, a second lifting ship and a transport ship are provided, the first lifting ship and the second lifting ship change draught and are close to an offshore platform, and a butt joint unit is in butt joint with the offshore platform; the first lifting ship and the second lifting ship reducedraught to support the offshore platform and enable the offshore platform to be separated from the jacket; and the offshore platform and the transport ship are made to move relatively, the offshore platform is placed on the transport ship, and the transport ship transports the offshore platform. The invention provides an offshore platform dismantling method. The offshore platform is subjected tobuoyancy dismounting based on cooperation of the three ships, the two lifting ships are in butt joint with the offshore platform, then the offshore platform is lifted up and separated from the jacket,and then the offshore platform is placed on the transport ship to be transported back to a wharf, so that the operation time is greatly shortened, the cost for dismounting the offshore platform is effectively reduced, and a brand-new scheme is provided.

    本发明公开了一种海上平台拆除方法,其包括:提供第一起升船、第二起升船和运输船,所述第一起升船和第二起升船改变吃水并靠近海上平台,使所述对接单元与海上平台对接;所述第一起升船和第二起升船减少吃水托起海上平台并使所述海上平台脱离导管架;使所述海上平台与所述运输船相对运动,将所述海上平台放置于所述运输船上,由所述运输船运输所述海上平台。本发明提供的一种海上平台拆除方法,基于三艘船协同将海上平台进行浮托拆除,通过两艘起升船与海上平台对接,然后将海上平台托起并脱离导管架,再将海上平台放置到运输船上运输回码头,大大缩短了作业时间,有效降低了拆除海上平台的成本,提出了一个全新的方案。
