Problems solved by technology

my country's South China Sea has a large water area and many proven oil and gas resources. Floating structures will be used in the development of oil and gas fields in the South China Sea, and semi-submersible production platforms are one of them. Semi-submersible production platforms have been used in foreign offshore oil development for decades. Relatively mature, and there is no actual production project in China using a semi-submersible production platform

Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] Such as Figure 1~4 As shown, the present invention proposes a deep-draft semi-submersible production platform with oil storage function, which includes a rectangular frame body composed of four bypasses 1 and four nodes 3 connected, and four nodes 3 A column 2 is respectively arranged on the top, and the tops of the four columns 2 jointly support an upper block 4 . Empty cabin 5, crude oil tank 6, ethylene glycol tank 7, ballast water tank 8, chain locker 9, reserved cabin 10 and channel 11 are arranged in four columns, wherein, crude oil tank 6 is used for storing a small amount of Crude oil, condensate oil, etc. Among them, condensate oil can be exported by small dynamic positioning tankers. This is the first time in the marine engineering field to adopt a method in a semi-submersible production platform. The empty cabin 5 on the side of t...

Abstract

The invention discloses a deep-draught semi-submersible production platform with an oil storage function. The deep-draught semi-submersible production platform is characterized by comprising a rectangular frame body which is formed by connection of four bypass pipes and four nodes, wherein a stand column is arranged at the top of each of the four nodes; the tops of the four stand columns together support an upper group block; an empty cabin, a ballast water cabin, a crude oil cabin, an anchor chain cabin and a passage for transporting personnel and cargo are arranged in the four stand columns; a ballast water cabin and a passage for pipeline arrangement, maintenance and inspection are arranged in the four bypass pipes; the upper group block adopts a plane box structure; and the upper group block is a carrier for the offshore oil and gas treatment equipment and a living building.

Description

technical field [0001] The invention relates to a deep-draft semi-submersible production platform with oil storage function, which belongs to the field of offshore oil development. Background technique [0002] In recent years, as my country's development of offshore oil and gas fields has gradually developed from shallow water to deep water, oil production platforms have gradually become larger. my country's South China Sea has a large water area and many proven oil and gas resources. Floating structures will be used in the development of oil and gas fields in the South China Sea, and semi-submersible production platforms are one of them. Semi-submersible production platforms have been used in foreign offshore oil development for decades. It is relatively mature, and there is no actual production project in China using a semi-submersible production platform. At present, the floating platform for developing oil and gas resources in the South my country Sea will have the foll...
