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 with reference to the 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 connected by four bypass 1 and four nodes 3, in the 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. In the four columns, there are empty tanks 5, crude oil tanks 6, glycol tanks 7, ballast water tanks 8, cable chain tanks 9, reserved tanks 10 and passages 11. Among them, the crude oil tank 6 is used to store a small amount of Crude oil, condensate oil, etc., of which the condensate oil can be transported by small dynamically positioned tankers. This is the first method adopted by the marine engineering community in a semi-submersible production platform. The empty tank 5 on the side of the column is used ...

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 large waters and many proven oil and gas resources. The development of South China Sea oil and gas fields will adopt floating structures. Semi-submersible production platforms are one of them. Semi-submersible production platforms have been used for decades in offshore oil development abroad. It is relatively mature, and there is no actual production project in China using semi-submersible production platform. The current floating platform for developing oil and gas resources in the South my country Sea will have the following characteristics: anti-typhoo...
