The invention discloses a jacket ocean platform upper module offshore installation method, which belongs to the technical field of offshore petroleum, and comprises the following steps: installing a transport frame on a self-propelled modular transport vehicle; the self-propelled modular transport vehicle and the transport frame jointly run into the lower part of the upper module on a construction site; the self-propelled modular transport vehicle and the upper module move along with the barge and move to a jacket sea area which is installed on the sea; mooring and continuously adjusting the load of the barge; the self-propelled modular transport vehicle lifts the upper module and transports the upper module to the jacket; and butting the upper block upright column leg with the top of the jacket guide pipe leg. According to the method, the self-propelled modular transport vehicle and the barge are used for installing the jacket ocean platform upper module on the sea, the solution thought except the floating crane hoisting method and the floating method installation method is provided, and the problems that floating crane resources are in shortage, the hoisting module cost is high, and the structural design cannot meet the floating method installation requirement are solved.
本发明公开了一种导管架海洋平台上部组块海上安装方法,属于海洋石油技术领域,包括以下步骤:将运输框架安装至自行式模块化运输车上;自行式模块化运输车和运输框架在建造场地上共同驶入上部组块下方;自行式模块化运输车和上部组块跟随驳船移动,且移动至在海上安装完成的导管架海域;将驳船系泊和持续调载;自行式模块化运输车举升上部组块,将上部组块运输至导管架上;将上部组块立柱腿与导管架导管腿顶部对接。本发明利用自行式模块化运输车,随驳船在海上实施导管架海洋平台上部组块的安装,提供了除浮吊吊装及浮托法安装两种方法以外的解决思路,解决了浮吊资源紧张,吊装组块费用高,结构设计无法满足浮托法安装的问题。
