Problems solved by technology

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the inability to organize the construction of each collector line and send out the submarine cable landing booster station before the upper block of the offshore booster station in the prior art, and the submarine cable cannot be installed in advance. The laying construction of the cable layer will seriously affect the progress of grid-connected power generation, resulting in huge economic losses, and the limited number of lifting ships used for the overall hoisting of the upper block, thus providing a method that can use more lifting ships for the upper group The overall hoisting of blocks, and after the completion of the lower foundation construction, it can meet the conditions for the construction of various collector lines and sending out submarine cables to land on the booster station, and the laying of submarine cables on the cable layer, and provide the necessary conditions for grid-connected power generation.

Embodiment Construction

[0030] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as there is no conflict with each other.

[0032] Such as figure 1 A specific implementation of the offshore step-up station shown includes a lower foundation, the bottom of which is fixed in the seabed 4, and a cable layer 1 is integrated in the part of the lower foundation that exceeds the sea level 3; the upper block 50 is installed on top of said...

Abstract

The invention relates to the technical field of wind farm construction, in particular to an offshore booster station, comprising a lower part foundation, the bottom end of which is fixed in the seabed, and a cable layer is integrated in the inner part of the lower foundation beyond the sea level; and an upper part block is mount on the lower part foundation. The offshore booster station provided by the invention can use more crane ships for the integral hoisting of the upper part block, and can be provided with various current collecting lines and a landing booster station for sending submarine cables after the lower part foundation construction is completed. The conditions for laying the submarine cables in the cable layer provide the necessary conditions for grid-connected power generation.

Description

technical field [0001] The invention relates to the technical field of wind farm construction, in particular to an offshore booster station. Background technique [0002] The offshore booster station includes the upper block and the lower foundation. The upper block has many constraints in its design, manufacture, construction and installation, while the lower foundation has fewer constraints and can be completed quickly. The conventionally designed interface is designed by integrating the submarine cable layer with the upper block. From the current planning of domestic offshore wind farms, the general capacity is 300-400MW. The hoisting weight of the upper block of a booster station for a 300MW-400MW offshore wind farm is about 3100T-3300T, and the weight eccentricity is about 0.5m-2.5 m. The design of the above interface will lead to two problems: 1. There are very few lifting ships that can be used for the overall hoisting of the upper module, and they are basically in ...
