Novel wet-dragging self-installation type offshore transformer substation and seabed big data center integral structure and installation and maintenance method

Abstract

The invention relates to a wet-dragging self-installation type offshore substation and seabed big data center integral structure and an installation and maintenance method. The wet-dragging self-installation type offshore substation and seabed big data center integral structure is mainly composed of an offshore substation upper module, an integral jacket, a seabed big data center module and lifting type connecting pile legs for connecting the upper module and the seabed big data center module. According to the invention, a wet-dragging self-installation type integral structure scheme is adopted, the device can be applied to a seabed big data center of an offshore transformer substation structure attached to medium and small upper modules (such as 200MW-500MW offshore booster stations), the application range is wide, the feasibility is high, the additional value of the offshore transformer substation is effectively improved, the electric energy access and data transmission requirements of the seabed big data center are met, and the cost is reduced. And the offshore construction operation flow of each stage of transportation, installation, service operation and maintenance is simplified.

Description

technical field [0001] The invention relates to an integrated structure and an installation and maintenance method of an offshore substation and a submarine big data center adopting a wet drag self-installation type, which is suitable for the field of marine engineering. Background technique [0002] In recent years, my country has become the country with the most newly installed capacity in recent years. At present, more than 20 small offshore substation structures of different types have been successfully built in China. With the development of offshore wind power to the deep sea and large capacity, while the steel structure consumption and offshore installation and construction costs of offshore substations continue to increase, the subsidies for offshore wind power have declined, and the yield of offshore substation products has dropped significantly. [0003] The large-scale offshore substation developed by the applicant before the application date integrates the new st...

Problems solved by technology

[0005] The purpose of the present invention is to take the integrated application of offshore substation + subsea IDC as the goal, and solve the problems that the existing small and medium-sized offshore substations cannot directly accommodate the subsea IDC, the offshore installation and construction cost of the upper block is high, and the connection between the subsea IDC and the upper block is difficult, etc. Provide a new type of wet towing self-installation offshore substation + seabed big data center overall structure and its technological process scheme, which can simplify the offshore construction operation process in each stage of transportation, installation, service operation and maintenance, reduce project cost, and improve the economy of the overall structure sex
