Abstract

The invention relates to a cylindrical FPSO folding and docking device and a method thereof. The docking device comprises a cylindrical ship body and a plurality of folding and docking modules, and the folding and docking modules are arranged on the cylindrical ship body; each folding butt-joint module comprises a main deck; a plurality of main deck buttresses which are integrally arranged on the main deck; a process deck which is arranged above the main deck; supporting stand columns, the upper ends of the multiple supporting stand columns and the process deck are integrally arranged, and the lower ends of the multiple supporting stand columns are in butt joint with the main deck buttresses one to one; a plurality of upper modules which are vertically and horizontally arranged on the process deck, and the upper modules and the process deck are integrally arranged. Integrated construction of the process deck and the upper module can be achieved, folding and butt joint can be completed only through one step, and the folding period can be greatly shortened.

Description

technical field [0001] The invention relates to the technical field of oil and gas exploitation, in particular to a cylindrical FPSO (Floating Production Storage and Offloading) closing and docking device and a method thereof. Background technique [0002] In recent years, with the development of offshore oil and gas fields in my country from shallow water to deep water, more and more floating platforms of various forms have been designed and used. Cylindrical FPSO has become one of the most widely used floating platform forms in recent years due to its comprehensive advantages of good motion performance, large oil storage capacity, deck area, and no need for single point mooring. At present, in the construction of floating platforms, the hull and upper modules are generally constructed separately to improve construction efficiency and shorten the construction period. However, the closing and docking operation needs to be carried out after the hull and the upper module are ...
