Prefabricated offshore booster station upper module and construction method thereof

Abstract

The invention discloses a prefabricated offshore booster station upper module and a construction method thereof. The upper module comprises a first-layer deck and a second-layer deck which are arranged on a jacket; a 35KV power distribution chamber and a screen body room are arranged on a left side of the second-layer deck, a main transformer chamber is arranged in the middle, a GIS power distribution chamber and an auxiliary equipment chamber are arranged on the right side, a screen body chamber is located above the 35KV power distribution chamber and connected with the 35KV power distribution chamber through a T-shaped hook, and the auxiliary equipment chamber is located above the GIS power distribution chamber and connected with the GIS power distribution chamber through a T-shaped hook; the main transformer chamber and the 35KV power distribution chamber are connected through a 35KV cable, the main transformer chamber and the GIS power distribution chamber are connected through a 220KV cable, and the 35KV cable and the 220KV cable are both located between the first-layer deck and the second-layer deck. According to the upper module and the construction method thereof, a modularprefabricated booster station is adopted, and the upper module and the construction method thereof have the advantages of being short in construction period, less in cross operation, low in management cost, less in redundant design and safe in construction.

Description

technical field [0001] The invention relates to an offshore booster station, in particular to a prefabricated offshore booster station upper block and a construction method thereof. Background technique [0002] Wind power is currently the mainstream industry of clean energy in the international community. It has significant social and environmental benefits and is of great significance to promoting the development of renewable energy in my country. In recent years, the development of wind power has been developed from land to sea. The construction of offshore wind farms generally consists of five major parts: wind farms, cable circuits between wind farms, offshore booster stations, outgoing cables, and on-road centralized control centers. The hub, the offshore booster station gathers the core electrical equipment of the entire wind farm, and is also the core of manual daily maintenance and operation. [0003] The offshore booster station is generally divided into the uppe...

AI Technical Summary

Problems solved by technology

[0004] At present, the construction of the offshore booster station is to carry out cross-construction of reinforced concrete and electrical modules on the sea. While building the platform, the electrical modules are installed at the same time. There are tight construction schedules, many cross-operations, long construction period, large construction area, and redundant design. Many, serious cost waste, unsafe construction and other shortcomings
