Deep seawater taking development and comprehensive utilization ocean platform and method thereof

Abstract

The invention relates to a deep sea water intaking development and comprehensive utilization ocean platform, a platform main body comprises an upper deck and a buoyancy tank which has a planar view angle and is profiled with the upper deck, the upper deck comprises a central area and three extension parts which extend from the central area to the periphery and are arranged at equal angles; the lower part of the extension part is fixedly connected with the buoyancy tank through a corner upright post; a center stand column used for storing deep seawater and increasing the waterline area is arranged at the center, located between the upper deck and the buoyancy tank, of the platform body. A deep seawater utilization facility is arranged in the central area above the upper deck; the deep sea water utilization facility is connected with a plurality of deep sea water taking pipes, surface sea water taking pipes and mixed sea water drainage pipes, and the deep sea water taking pipes, the surface sea water taking pipes and the mixed sea water drainage pipes penetrate through the upper deck and extend downwards into sea water.

Description

technical field [0001] The invention relates to an ocean platform, in particular to an ocean platform for deep sea water intake development and comprehensive utilization, and belongs to the technical field of ocean platforms. Background technique [0002] Deep seawater has excellent characteristics that are different from surface seawater and other water resources, such as cleanness, eutrophication, and low temperature stability. With the deepening of people's research on deep seawater, the important value and application prospects of deep seawater in the fields of medical care, agricultural planting and aquaculture are gradually becoming known to the world. [0003] The average water depth of the South China Sea is 1212m, and it is the only sea area among the four major sea areas in my country that has the conditions for deep seawater development. But even in the South China Sea, there are still no deep seawater resources close to the land. Therefore, if you want to develo...

AI Technical Summary

Problems solved by technology

[0005] 1) Consumption of a large amount of energy and pollution: the daily production and daily life of conventional floating offshore platforms are generally provided by large diesel generators, which consume a large amount of non-renewable fossil energy and cause pollution to the marine environment

[0006] 2) The cost of obtaining fresh water is high: the working sea area of ​​the floating offshore platform is often in the deep sea far away from the mainland, and there are no fresh water resources available nearby. The fresh water needed for the daily production and life of the platform often requires regular replenishment by transport ships, and the cost of fresh water transportation is high

[0007] 3) It is not conducive to the storage of deep seawater: the floating ocean platform with relatively mature technology in my country is a semi-submersible platform, and the conventional semi-submersible platform is mostly four-column or six-column type, and deep seawater is stored in one or several columns It is easy to cause changes in the floating state of the platform, which will have an adverse effect on the stability of the platform.
