Abstract

The invention relates to a cylindrical FPSO closing and docking device and a method thereof, wherein the docking device includes a cylindrical hull and several closing and docking blocks, and the several closing and docking blocks are arranged on the cylindrical hull ; Each of the combined docking blocks includes: main deck; main deck buttresses, a plurality of main deck buttresses are integrally arranged on the main deck; craft deck, arranged above the main deck; supporting columns The upper ends of the several supporting columns are integrated with the process deck, and the lower ends of the several supporting columns are connected with the main deck pier one by one; the upper blocks are arranged vertically and horizontally on the on the craft deck, and is set integrally with the craft deck. The present invention can realize the integrated construction of the process deck and the upper block, only needs one step to complete the closing and docking, and can greatly reduce the closing period.

Description

Method of closing and docking of cylindrical FPSO technical field The present invention relates to the technical field of oil and gas exploitation, specifically about a kind of cylindrical FPSO (Floating Production Storage and Offloading, floating production oil storage and offloading device) closing and docking method. Background technique In recent years, with the development of offshore oil and gas fields in my country gradually from shallow water to deep water, various forms of floating platforms Begin to be more and more designed and used. Cylindrical FPSO relies on good sports performance, large oil storage capacity, deck surface It has the comprehensive advantages of not requiring single point mooring, and has become one of the most widely used floating platform forms in recent years. Currently, floating In the construction of the type platform, the hull and the upper block are generally constructed separately to improve the construction efficiency and short...
