Problems solved by technology

Due to the small displacement, the platform does not have a central well, so it is not possible to use dry oil collection trees and top tension risers, and only wet wells and rigid catenary risers can be used, which makes it unable to meet drilling requirements, and oil production Equipment installation and maintenance are more difficult and expensive

Abstract

A multi-column trussed-beam upright column platform with central well belongs to marine engineering technology field. The invention include: top module, hard cabinet, central cylinder, trussed structure, soft cabinet and mooring system. The top module is connected with the upper part of hard cabinet through the deck legs, the hard cabinet encircles surround the central cylinder, the lower part of hard cabinet is connected with trussed structure, the lower part of trussed structure is connected with soft cabinet. The mooring system is connected with the outer part of hard cabinet. Said central cylinder includes: central cylinder shell, central well and reinforced beam structure. The central well is installed in the central cylinder shell through the reinforced beam structure. The central cylinder of the invention is equipped with central well in itself, so it enables the installment of buoyancy tank and top tensioning stand pipe, due to the stand pipe system is decoupled with the movement of platform, while is protected by platform main body, so it can maintain smaller movement and bears smaller environmental loads, thereby the dry collected oleoresin can be used on the platform, it is facilitating for installment and maintenance of the equipment.

Description

technical field [0001] The invention relates to a platform in the technical field of marine engineering, in particular to a multi-column truss-type column platform with a central well. Background technique [0002] Petroleum, as the main source of world energy supply, has become an important strategic resource to promote national economic development. In recent years, the growth of offshore oil and gas production has become the main source of my country's self-produced oil and gas increment. With the continuous expansion of the scale of human development of marine oil and gas, the development of shallow sea oil and gas resources has become increasingly saturated. The development of offshore oil and gas exploration and development from shallow sea to deep sea has become an inevitable trend. The single-column platform can significantly reduce the load, optimize the structural design, and reduce the manufacturing cost. Compared with other deep-sea platforms, the investment co...
