Embodiment 1

[0054] Such as Figure 1-3 As shown, a seawater three-dimensional oil tank platform includes at least three piles or buoyancy cylinders 6 connected to the seabed 11, and also includes an underwater oil tank 7 connected between all the piles or buoyancy cylinders 6, and The support frame 4 that is arranged on the top of all the piles or buoyancy cylinders 6, above the support frame 4 is provided with an oil tank 3 on the water, and the underwater oil tank 7 is connected with several anchors on the seabed or seabed 11 Gravity anchor 10, the underwater oil tank 7 is located below the sea level 5, the above water oil tank 3 is located above the sea level 5, and the cavities of the underwater oil tank 7 and the underwater oil tank 7 communicate with each other.

[0055] Specifically, such as figure 2 As shown, the above-mentioned water oil tank 3 and the underwater oil tank 7 are connected by pipelines, and switch valves are arranged between the pipelines; each unit of the underw...

Embodiment 2

[0066] Such as Image 6 As shown, Embodiment 2 also provides a seawater three-dimensional oil tank system, including several seawater three-dimensional oil tank platforms as in Embodiment 1, and all seawater three-dimensional oil tank platforms are connected in parallel to form a row or Arrayed seawater three-dimensional oil tank system. The seawater three-dimensional oil tank system consists of several seawater three-dimensional oil tank platforms connected in parallel to form a row or array seawater three-dimensional oil tank system, which can effectively meet the needs of actual submarine oil and gas development and oil and gas storage, and facilitate construction and efficient use of water. The adjacent connection positions of the two platforms can share piles or buoyancy cylinders 6 .

[0067] The basic structure and construction method of the seawater three-dimensional oil tank system are similar to those of Embodiment 1, and the same parts will not be repeated here. ...

Embodiment 3

[0069] The present invention also provides a construction method of a seawater three-dimensional oil tank platform, that is, a construction method of a seawater three-dimensional oil tank platform in Embodiment 1, comprising the following steps:

[0070] Step 1, install piles or buoyancy cylinders 6, float all the piles or buoyancy cylinders 6 required by the platform to the site, drive all the piles or buoyancy cylinders 6 into the seabed 11 and fix them, and The piles or buoyancy cylinders 6 are located at the part above the sea level 5 and the support frame 4 is installed, and all the piles or buoyancy cylinders 6 are connected to each other;

[0071] Step 2: Install the underwater oil tank 7, first float the gravity anchor 10 under the platform, first install the underwater gravity anchor 10 and the reserved anchor chain, and then float the underwater oil tank 7 under the platform, stretch Exit the top pressure rod 8, stop when it reaches the surface of the pile or buoyanc...

Abstract

The invention relates to a marine three-dimensional oil tank platform, system and a constructing method of the marine three-dimensional oil tank platform. The marine three-dimensional oil tank platform comprises at least three pile columns or at least three buoyance cylinders connected to the bottom of the sea, an underwater oil tank connected between all the pile columns or all the buoyance cylinders and a supporting frame arranged at the top of all the pile columns or all the buoyance cylinders, wherein an aquatic oil tank is arranged on the supporting frame; a plurality of gravity anchors anchored to a seabed or a sea bottom are connected to the underwater oil tank; the underwater oil tank is located below a sea level, and the aquatic oil tank is located above the sea level; a cavity ofthe underwater oil tank mutually communicates with a cavity of the aquatic oil tank; the system comprises a plurality of seawater three-dimensional oil tank platforms which are in parallel connection; and the pile columns or the buoyance cylinders can adopt the buoyance cylinders and a sea bottom fixing system of the buoyance cylinders or the pier columns and a sea bottom fixing system of the pier columns. The marine three-dimensional oil tank platform disclosed by the invention is simple in structure and optimized in design, after the marine three-dimensional oil tank platform floats to an offshore region, only a small quantity of working capacity of assembling and reinforcing is needed, so that the constructing difficulty of an offshore platform and the investment of offshore transporting and assembling equipment are reduced, and the construction cycle is shortened; and the constructing method is easy to construct, high in reliability, and suitable for oil gas exploitation work in the marine field.

Description

technical field [0001] The invention relates to the technical field of marine engineering equipment, in particular to a seawater three-dimensional oil tank platform, a system and a construction method thereof. Background technique [0002] Building large-scale permeable platform facilities in the ocean can become a material supply base for oil and gas storage, fishing, and marine activities, laying the foundation for my country to gradually increase ocean development and accelerate the development of ocean areas. [0003] Offshore platforms are divided into floating offshore platforms and fixed offshore platforms according to whether their positions are fixed or not. The specific structure of each seawater platform is as follows: [0004] A floating seawater platform is an oil storage facility, specifically anchoring or anchoring an oil storage ship, an oil storage tank or other types of oil storage devices in a specific sea area for receiving, storing and transshipping oil....
