Seawater three-dimensional oil tank platform, system and construction method thereof

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....

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to avoid the problems of high construction difficulty, high cost and low stability in relatively ocean areas of the existing seawater platform existing in the prior art, and provide a simple construction, low cost, which can adapt to relatively large Built in deep waters and different seabed geological structures, it is not affected by the climate, and the seawater three-dimensional oil tank platform and system with strong stability also provides a construction method for the three-dimensional oil tank platform
