Embodiment Construction

[0023] The present invention will be further described below in conjunction with the drawings.

[0024] The new marine deep-water pontoon platform (hereinafter referred to as S-Spar) provided by the present invention is a new-type Spar platform designed for the development of deep-water oil and gas fields in the South my country Sea. This invention absorbs the deep draft characteristics of the existing foreign Spar platform structure. Significant improvements have been made to make S-Spar’s comprehensive performance more suitable for applications in my country’s South China Sea deep-water oil and gas fields.

[0025] S-Spar's overall plan is as follows figure 1 As shown, in the design scheme, the hard cabin 2 and the soft cabin 4 below the platform deck 1 are directly rigidly connected by a cylindrical central well 3. Therefore, the diameter of the middle section is small, and therefore, the hydrodynamic load is small. In order to increase the heave damping, three layers of heave...

Abstract

The invention relates to an ocean working platform, in particular to a novel ocean deepwater floating pontoon platform. The structure of the platform comprises a platform deck for operating, wherein a hard cabin is connected under the platform deck; a plurality of mooring ropes are connected on the outer wall of the hard cabin, while the other ends of the mooring ropes are connected with a submarine anchorage ; a soft cabin is arranged under the hard cabin; the hard cabin and the soft cabin are connected through a cylindrical center well; a plurality of layers of heave plates are vertically arranged outside the center well; the heave plates along circumferential direction is symmetrically provided with a plurality of square holes; and a plurality of oil extraction vertical pipes pass through the center well to a submarine well mouth. Compared with the prior Spar platform, the novel ocean deepwater floating pontoon platform has strong supporting capability and low structure cost, and is applicable to abyssalpelagic operation with internal waves.

Description

Technical field [0001] The invention relates to an ocean working platform, in particular to a new type of ocean deep-water buoy platform. Background technique [0002] Current deep-water oil and gas field development mainly uses deep-water buoy platforms (Spar platforms) or tension-leg platforms (TLP platforms) as production platforms. Among them, the Spar platform has a larger applicable water depth and is more widely used. The Spar platform belongs to the category of compliant platforms and is widely used in human development of deep seas. It is responsible for various tasks such as drilling, production, offshore crude oil processing, oil storage, and loading and unloading. It has become a powerful tool for deep-sea oil exploration in the world today. The main body of the Spar platform can be divided into several parts, some of which are fully enclosed structure, and some of which are open structure. There is a central well in the center, and an independent riser pontoon is ins...
