Embodiment Construction

[0033] The offshore booster station 1 that needs to be installed in this embodiment has a capacity of 200MW and a voltage level of 220kV. The planar size of the offshore booster station is 30m×30m, and the overall weight is 1800t; in view of this, this example uses a 5000t-class barge 2 for floating and installation. The barge 2. The length of the ship is 80m and the width is 24m, so as to adapt to the weight of the offshore booster station 1, that is, the load capacity of the barge 2 should be able to safely carry the weight of the entire offshore booster station 1, and its stability should meet the requirements of the barge 2 and the offshore booster station. The stability requirements of Station 1 when hauling at sea; the bottom of the barge 2 is provided with a plurality of pressurized water tanks 21 whose water volume can be adjusted freely. The depth of the draft.

[0034] The specific installation steps are as follows:

[0035] a. Complete the construction of the offsh...

Abstract

The invention relates to a buoyancy type mounting method for an offshore boosting station, which aims to be safe and high-efficiency, save expense and have low requirements on ship machines and equipment. The technical scheme includes that the buoyancy type mounting method for the offshore boosting station is characterized by comprising steps of a, building the offshore boosting station on the land; b, sliding the offshore boosting station on a barge, conveying the offshore boosting station to a specified mounting position, judging whether the bottom of a support of the offshore boosting station is higher than the top end of a foundation or not, executing a step d if the bottom of the support of the offshore boosting station is higher than the top end of the foundation, and executing a step c if the bottom of the support of the offshore boosting station is not higher than the top end of the foundation; c, controlling the barge to ascend; d, leading the barge to move into a gap of the middle of the foundation and positioning the barge; e, controlling the barge to descend, placing the support of the offshore boosting station on the foundation, simultaneously, leading the barge to continue descending until the barge is separated from the offshore boosting station, and then dragging the barge out from the bottom of the offshore boosting station; and f, welding the support with the foundation. The buoyancy type mounting method is applicable to the field of offshore wind power generation.

Description

technical field [0001] The invention relates to an installation method of an offshore booster station, in particular to a float-over installation method of an offshore booster station, which is mainly applicable to the field of offshore wind power generation. Background technique [0002] In my country, offshore wind power generation is an emerging industry. After 2007, my country began to gradually develop the offshore wind power industry. my country's offshore wind power industry is still in its infancy. At present, the domestic offshore wind farms that have been built send the electric energy generated by wind turbines to the land, and then send it to the power grid after being boosted by the land booster station. With the development of my country's offshore wind power generation technology, offshore wind farms are getting farther and farther offshore, and the scale of wind farms is getting bigger and bigger. The traditional way of setting up onshore booster stations on ...
