Abstract

The invention discloses a novel jacket platform suitable for offshore oil and gas exploitation, which comprises an underframe (1) and a platform deck (2), and a support frame (3) is arranged between the underframe (1) and the platform deck (2); a plurality of flow control assemblies are arranged in the supporting frame (3), each flow control assembly comprises a flow control base (4) fixed in the supporting frame (3), a plurality of mounting grooves (41) are formed in each flow control base (4), flow control plates (5) are rotationally arranged in the middles of the mounting grooves (41), and the movable ends of the flow control plates (5) extend to the outer sides of the mounting grooves (41). The jacket platform has the advantage that the influence of wind, waves and flow on the jacket platform is reduced.

Description

technical field [0001] The invention relates to the technical field of offshore oil and gas resource development, in particular to a novel jacket platform suitable for offshore oil and gas exploitation. Background technique [0002] As the base of marine resource production activities, the offshore platform is the key equipment for the development of marine resources. Up to now, there are more than a thousand offshore platforms put into production and use, which have gone through the process from the initial shallow water wooden fixed structure to the deep water steel moving complex form. Among them, the jacket platform is the most widely used platform form in the world, accounting for more than 90% of the total, and it is also the most used offshore platform in my country. It has the characteristics of high safety and economy, convenient design and installation, suitable for different soil properties and strong practicability in shallow water areas. [0003] Jacket platfo...
