Underwater buoyancy tank separation structure and separation method suitable for hexagonal barrel type foundation overwater prefabricated platform

Abstract

The invention discloses an underwater buoyancy tank separation structure and separation method suitable for a hexagonal barrel type foundation overwater prefabricated platform. The underwater buoyancy tank separation structure comprises a main body platform, the four corners of the main body platform are respectively provided with a permanent dry cabin, the lower parts of separation type buoyancy tanks are provided with a clamping rack, the lower part of the clamping rack is provided with a group of rollers, the permanent dry cabin is provided with a buckle matched with the clamping rack at a position corresponding to the clamping rack, and an air cushion is also arranged between the permanent dry cabin and a separation type buoyancy tank. According to the underwater buoyancy tank separation structure and separation method suitable for the hexagonal barrel type foundation overwater prefabricated platform, the mode that the separation type buoyancy tanks are transferred from the platform is adopted, the use space of the platform can be fully utilized, the construction cost of the platform is saved, meanwhile, the risk of transferring a barrel type foundation is reduced, the operation that two floating body structures of a floating ship and the hexagonal barrel type foundation are connected in the floating state in water is avoided, and foundation transferring is more efficient and safer. Meanwhile, auxiliary devices for transferring the hexagonal cylindrical type foundation are reduced, so that the foundation transferring operation is more convenient, and the cost is lower. In addition, a separation type buoyancy tank device is simple in structure and can be repeatedly used.

Description

technical field [0001] The invention relates to the technical field of offshore wind power, and is a method suitable for separating the main part of a hexagonal cylindrical foundation offshore prefabricated platform from a buoyancy tank, realizing safe and fast transfer of the hexagonal cylindrical foundation out of the prefabricated platform, and convenient transportation. Background technique [0002] Wind energy is the most competitive renewable clean energy. In particular, offshore wind energy has the characteristics of rich resources and high quality, and has been rapidly developed and utilized in the past 20 years. As the development of offshore wind resources cannot meet the growing demand for energy, offshore wind power will gradually develop in the deep sea. [0003] The traditional foundation form cannot meet the requirements under the complex wind, wave, current and other environmental conditions in the deep sea. The type basis is proposed. The basic structure ...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the existence of the existing large-size buoyancy tanks restricts the transfer and removal direction of the cylindrical foundation, and prevents floating ships from entering the upper part of the prefabricated platform on the water. For the problem of foundation connection, provide a structure and separation method suitable for the separation of the main part of the offshore prefabricated platform of the hexagonal cylindrical foundation and the underwater buoyancy tank. This method can realize safe and efficient transfer of the hexagonal cylindrical foundation, and effectively utilize Platform construction operation space
