A self-generating semi-submersible ocean platform

Abstract

The invention provides a self-power generation type semi-submersible ocean platform. The self-power generation type semi-submersible ocean platform comprises an ocean platform main body and multiple gas column type platform struts, wherein the ocean platform main body is higher than the sea level; and the multiple gas column type platform struts are used for supporting the ocean platform main body. The gas column type platform struts comprise uprights and platform buoys; the uprights are connected to the upper parts of the platform buoys; the gas column type platform struts are of cavity structures; cavities of the uprights vertically run through the uprights and the platform buoys; turbines capable of rotating in the same direction under the action of double-way airflow are arranged in gas passage parts; the turbines are connected with a power generator in the ocean platform main body; and at least one valve used for regulating the flow of the passing airflow is arranged on each gas passage part under each turbine. According to the self-power generation type semi-submersible ocean platform, waves can be utilized to generate power, and the flowing speeds of gases in the gas passageparts can be controlled by using the valves, the heaving performance of the platform is improved, and the power utilization of the ocean platform is preferably guaranteed.

Description

technical field [0001] The invention relates to the technical field of ocean engineering, in particular to a self-generating semi-submersible ocean platform. Background technique [0002] An offshore platform is a structure that provides production and living facilities for activities such as exploration, drilling, oil production, consolidation, observation, and construction at sea. Semi-submersible platform, as a commonly used offshore platform, is mainly composed of an upper structure, a lower buoy box and columns, and the upper structure is used to install drilling machinery and platform operating equipment. The semi-submersible platform has the advantages of wide operating water depth range, small water surface area, strong resistance to wind and waves, and large variable load. [0003] Because the lower part of the semi-submersible platform is submerged in water, its roll and pitch amplitudes are very small, and the natural vibration period of the semi-submersible plat...

But these methods all change the main scale of the platform

At the same time, because the platform is far away from the inland, the power required by the offshore platform usually requires 3–5 marine diesel generators to operate in parallel. This method of self-power generation not only pollutes the environment, but also brings a lot of inconvenience to the use of the platform.
