Double-curved-surface floating type production oil storage platform

Abstract

The invention discloses a double-curved-surface floating type production oil storage platform. The platform comprises a floating body and a production deck. The vertical section of the floating body is of a uniparted hyperboloid shape or a rotary uniparted hyperboloid shape. A cylindrical central cabin is disposed in the middle of the floating body and along the axial direction of the floating body. An annular oil storage canine is disposed along the outer wall of the central cabin. The production deck is disposed on the upper end face of the floating body and provided with an oil-gas processing module, a water injection module, a water processing module, a power supply and distribution module, an auxiliary production module and a living building module. The platform has the advantages that the inherent defects of ship FPSO are overcome, the advantages of convenient moving and repeated using of traditional FPSO are inherited, stability and hydrodynamic performance of the platform are further improved, oil storage efficiency and bearing capacity are increased, building difficulty and cost are lowered, and a novel device is provided for efficient development of offshore oil fields.

Description

technical field [0001] The invention relates to a hyperboloid floating oil production and storage platform, which belongs to the technical field of marine engineering. Background technique [0002] FPSO (Floating Production Storage and Offloading System) is an offshore floating oil and gas processing device that integrates oil and gas processing, oil storage and offloading, heating, power generation, control and living functions. System (upper module), oil storage and unloading system (container-like floating body) and mooring system are composed of three major parts. [0003] The performance of FPSO is mainly examined through its safety and operability and the satisfaction of functional requirements. In terms of safety and operability, FPSO should have good stability and hydrodynamic performance; in terms of functional requirements, FPSO should have large oil storage capacity, carrying capacity and deck area. The shape of the floating body of FPSO determines its safety, m...

AI Technical Summary

Problems solved by technology

[0013] The purpose of the present invention is to provide a hyperboloid floating production and storage platform. The present invention can solve the problem of poor motion performance of FPSO by utilizing the difference between the ballast tank at the bottom and the size of the upper and lower bottom surfaces of the hyperboloid and at the bottom. Add fixed ballast to adjust the position of the center of gravity so that it is located below the center of buoyancy, and increase the height of the center of buoyancy through the deep draft design, so that the platform becomes an unconditionally stable floating body. Under this premise, the self-weight of the structure can be reduced , reduce construction and operating costs
