Abstract

The invention relates to a cylindrical FPSO suitable for a multi-point mooring system, which comprises a ship body and an upper module mounted on the ship body, the ship body comprises a damping plate; a cylindrical barrel which is installed on the damping plate, the interior of the cylindrical barrel is divided into a void cabin, a crude oil cabin and a ballast water cabin, and a load discharging system and a channel are arranged in the void cabin; and an outer floating structure which is located at the top of the cylindrical barrel, and the upper module is installed on a main deck of the outer floating structure. The cylindrical FPSO suitable for the multi-point mooring system is suitable for multi-point mooring, and the cost is reduced. In addition, the separated cabins in the cylindrical barrel are annularly arranged, the space utilization rate is high, and the cabin capacity of the crude oil cabin is large.

Description

technical field

[0001] The invention belongs to the field of offshore oil development, in particular to a cylindrical FPSO suitable for a multi-point mooring system. Background technique

[0002] FPSO (Floating Production Storage and Offloading), that is, floating production storage and offloading device, can perform preliminary processing and storage of crude oil, and is called "offshore oil factory".

[0003] my country's South China Sea waters cover a large area, the water depth varies greatly, and there are many proven oil and gas resources. Floating structures + jackets / underwater production systems + submarine pipelines are usually used to develop oil and gas fields in the South China Sea. FPSO is the most important facility in floating structures one. At present, there are as many as a dozen FPSOs operating in the South China Sea, all of which are ship-type FPSOs. They have been successfully used in domestic offshore oil development for more than 30 years, and the des...
