Installation method of reusable jacket platform
The invention discloses a mounting method of a reusable jacket platform. The mounting method comprises the following steps: designing a jacket into a split structure of an upper jacket and a lower jacket; transporting to an installation site through a transportation barge; hoisting the lower jacket by using a floating crane, and lowering and fixing the lower jacket to a seabed; hoisting the upper jacket by using a floating crane, and mounting the upper jacket to the top end of the lower jacket; the upper platform is installed through a floating crane, drilling and production operation can be conducted after connection and debugging, and installation of the jacket platform is completed; after the service life of the oil field is over, upper platform equipment and pipelines are all cleaned and disconnected; pulling the whole jacket out of the seabed through a floating crane; towing the jacket by using a tug, moving to a new oil field mounting position, and mounting the jacket again; a floating crane is used for installing the upper platform, new oil field drilling and production operation can be carried out after connection and debugging, and repeated utilization and installation of the jacket are completed. The construction efficiency is greatly improved, the construction period is shortened, and the construction cost is saved.
本发明公开了一种可重复利用的导管架平台的安装方法，包括以下步骤：将导管架设计为上部导管架和下部导管架的分体式结构；通过运输驳船运输至安装现场；使用浮吊起吊下部导管架，并下放固定到海床；使用浮吊起吊上部导管架，将上部导管架安装至下部导管架顶端；使用浮吊安装上部平台，连接调试后可进行钻采作业，完成导管架平台的安装；油田寿命结束后，将上部平台设备和管线全部清理并断开连接；通过浮吊将导管架整体拔出海床；使用拖轮拖带导管架，前往新油田安装位置，再次安装导管架；使用浮吊安装上部平台，连接调试后可进行新油田钻采作业，完成导管架的重复利用安装。本发明大大提高了施工效率，降低了施工工期，节约了施工费用。
