Self-elevating floating bracket installation method of drilling platform

WANG LEI / TANG ZIYING / HE HUACHENG

The invention discloses a self-elevating floating bracket installation method of a drilling platform. The method solves the problems of low installation efficiency, high requirements for manual control and high unsafe factors of traditional floating brackets. According to the main point of the technical scheme, upper components of the drilling platform are transported to a designated constructionsea area by a dynamic positioning barge. The upper components of the drilling platform are ascended to a designated operating height through an adaptive lifting system to perform lifting adjustment tocomplete the operation. The self-elevating floating bracket installation method of the drilling platform solves the traditional problems, and the lifting operation during floating bracket installation is more efficient and safer.

本发明公开了一种钻井平台的自升式浮托安装方法，解决了传统浮托安装效率低、对于人工控制要求高、不安全因素高的弊端，其技术方案要点是通过动力定位驳船将钻井平台上部组件运输至指定施工海域，并通过自适应升降系统进行升降调整将钻井平台上部组件上升至指定作业高度，完成作业，本发明的一种钻井平台的自升式浮托安装方法，解决传统存在的问题，浮托安装过程升降作业更加的高效、安全。
