A floating production platform

Abstract

The invention relates to a floating production platform, which comprises a floating body in octagonal prism structure, an upper deck is fixed on the top of the floating body; an oil and gas processing unit and a drilling unit are arranged on the upper deck; moon pool; a plurality of first suspension supports are evenly fixed on the outer wall surface of the lower part of the floating body at circumferential intervals, and each first suspension support is hinged with one end of a steel pipe arranged vertically downward through a hinge mechanism; each steel pipe The other end of the bridge is hinged with the second suspension support through a hinge mechanism, and each second suspension support is hinged and fixed on the circumferential edge of the horizontally arranged heave plate; There are through holes equal to its size. Because the present invention is hinged with a heave plate under the floating body, it can effectively reduce the heave amplitude of the floating body, improve the motion performance of the device of the present invention, and at the same time have a deep-draft column platform and a floating production, oil storage, and oil unloading device function.

Description

technical field [0001] The invention relates to a floating production platform, which belongs to the technical field of deep water oil and gas field development. Background technique [0002] With the increasing demand for energy in the world and the continuous maturity and perfection of shallow water development technology, the development of deep water has become the development trend of the world's offshore oil. Since the exploration and development of deep-water oil and gas fields is a high-investment and high-risk project, the construction of oil and gas fields must first consider economic benefits. According to the current situation of domestic marine engineering resources, technical equipment and environmental conditions in the South China Sea, my country has proposed the development of a new type of floating production device suitable for the development of deepwater oilfields in the South China Sea. FDPSO (floating drilling, production, storage and offloading unit,...

Problems solved by technology

However, due to the large waterline area of ​​the hull and the limited draft, although it has good stability, its heave performance is difficult to control.

Under operating conditions, the large heave amplitude increases the risk of drilling operations and shortens the operation period, which seriously affects the operation efficiency, and the large heave motion also brings great challenges to the design of the riser
