Description
Technical Field
The invention relates to an underwater oil storage tank foundation structure, in particular to a foundation structure which is arranged on the sea bottom and used for placing an underwater oil storage tank.
Background
The underwater oil storage technology has been applied abroad mainly as a temporary oil storage facility for a marine oil field, which is arranged on a seabed and generally stores crude oil which is just produced in the temporary oil storage facility for loading and unloading by an oil tanker.
China generally arranges an oil storage device directly at a port with crude oil receiving capacity, and crude oil unloaded by an oil tanker is directly stored in the area of the port.
The proportion of crude oil import is higher in China, but the storage capacity of crude oil is less, and once the crude oil import is interrupted, the crude oil stored in China can only meet the short-term requirements of China. On the other hand, the crude oil receiving capacity of ports in China is limited, and the situation that oil tankers cannot enter the ports after being queued outside the ports for a long time appears when a large amount of crude oil is imported in China.
Arranging an underwater oil storage facility offshore at a port is an effective scheme for solving the problems, on one hand, an oil tanker oil unloading channel is added, the oil tanker is allowed to directly unload the crude oil to the underwater oil storage facility without entering the port, and the crude oil receiving capacity of the port is enhanced; on the other hand, the land area of a port is not occupied so as to add an oil storage tank, and the crude oil storage capacity is improved.
