The invention discloses a double-ship floating type ocean platform dismantling method, which belongs to the technical field of ocean platform dismantling, and is characterized in that the double-ship floating type ocean platform dismantling method comprises two crane ships provided with motion compensation devices, two connecting arms directly contacted with an upper module and a transport ship. After the upper module and the jacket of the ocean platform are cut, the two crane ships carry out load arrangement to reduce the draft, the upper module is integrally lifted through the connecting arm connected with the motion compensation device, and the upper module is made to be away from the jacket and transported to the position above the transport ship. The motion compensation device controls the actuator to act by detecting the postures of the crane ship and the connecting arm so as to keep the contact point of the actuator and the connecting arm stable, and the stability of the upper module in the lifting and transporting process is guaranteed. When the ocean platform is dismantled through the ocean platform dismantling device, the using length of the connecting arm and the connecting position of the connecting arm and the motion compensation device can be selected according to an operation object, applicability is high, meanwhile, using of a large floating crane and renting of an expensive special floating ship are avoided, and therefore cost is greatly reduced.
本发明公开了一种双船浮托式海洋平台拆除方法,属于海洋平台拆除技术领域,其特点是:包括两艘装有运动补偿装置的起重船、两根直接与上部组块接触的连接臂以及运输船。在将海洋平台的上部组块和导管架切割后,两艘起重船排载减小吃水,通过与运动补偿装置连接的连接臂对上部组块进行整体托举,并使上部组块远离导管架,运输至运输船上方。此间运动补偿装置通过检测起重船及连接臂姿态,控制作动器作动以保持与连接臂接触点稳定,保证上部组块在举升及运输过程中的稳定。利用本发明进行海洋平台拆除,可根据作业对象选择连接臂使用长度及与运动补偿装置的连接位置,适用性强,同时,避免使用大型浮吊以及租赁昂贵特种浮托船,从而大幅度降低费用。
