Floating structure, large-scale offshore floating energy station and mounting method of large-scale offshore floating energy station

Abstract

The invention relates to a floating structure, an offshore large floating energy station and an installation method of the offshore large floating energy station. The method is suitable for ocean engineering. According to the technical scheme adopted by the invention, the floating structure is characterized by comprising a deck layer and a floating layer, the floating body is fixedly mounted below the deck layer and used for providing buoyancy for the deck layer; the lateral floating wing structures are fixedly mounted on the two sides of the deck layer and used for improving the overall stability of the deck layer; the floating body is provided with spherical floating bodies evenly arranged below the deck layer, every two adjacent spherical floating bodies are connected through a flexible hinge, and the top of each spherical floating body is fixedly connected with the deck layer through a suspension device. An offshore large floating type energy station is characterized by comprising the floating body, an energy station equipment room is arranged on the deck layer, and mooring cables used for fixing the energy station to a designated sea area are fixedly installed on the periphery of the deck layer.

Problems solved by technology

[0002] At present, it is difficult for a single offshore wind power business to form an obvious competitive allocation advantage, and it is urgent to integrate more related industries to improve the income of offshore wind farms, such as offshore hydrogen production, sea rescue and other businesses

However, with the development of offshore wind farms into the deep sea, the construction and installation costs of multiple deep-water fixed platforms (offshore substations, offshore hydrogen production stations, offshore living platforms, and offshore rescue platforms) will increase sharply, and the increase in water depth will directly As a result, the projected area of ​​the lower foundation on the seabed increases, which increases the distance between the upper blocks, makes it difficult to set up the connecting bridge, and increases the workload of maintenance personnel in the later stage of operation and maintenance.

Regardless of the initial investment and later operation and maintenance, this type of energy platform cluster has obvious disadvantages, and cannot meet the development concept of cost reduction, efficiency increase, and intensive use of the sea

On the other hand, the single module of the existing ultra-large offshore floating structure is relatively large in size, which is easily subject to sagging or arching deformation of the floating body module, resulting in huge stress problems. The existing ultra-large offshore floating structure and multi-industry The direct combination of multi-service platforms cannot guarantee the reliable operation of precision equipment such as electrical and hydrogen production, which will affect the normal operation of offshore wind farms
