Problems solved by technology

However, for offshore converter stations, due to the characteristics of large span, small structural rigidity, and equipment vibration sensitivity, the traditional float-over installation method for offshore converter stations may have excessive structural deformation and equipment failure. Risk of damage due to vibration

Embodiment Construction

[0034] Referring to the drawings and specific embodiments of the present invention will be further described in detail.

[0035] (1) such as Figure 1 ~ 3As shown in offshore topside converter station 1 and the floating vessel 2 Torr composition float system. Land 3 free start of construction, i.e., the upper block 1 and the support frame 12 by a shoe 13 located in the upper rail 4, and moved by the float-ship slide rail 4 after the completion of construction of the two. Bilaterally floating vessel holder 2, the anti-shake floating body 21 is provided by a fixed frame 22 fixed to both sides of the ship. Closed box structure 21 of the anti-shake with steel floating body is provided with internal reinforcing ribs and drainage, water injection system. Anti-shake floating body on the side of the ship and the ship's side connector 21, the fixed frame 22 is provided with an upper deck of the ship are connected. Before shipment, the anti-shake float 21 and the fixed frame 22 mounted on a ...

Abstract

The invention provides a floating type installation structure and method for an offshore converter station, the floating type installation structure for the offshore converter station comprises a floating ship, anti-swing floating bodies are arranged on the two sides of the floating ship, each anti-swing floating body is composed of a floating box and a fixed frame, a drainage and water injection system is arranged in each floating box so as to inject water into a lower layer when an upper module is loaded, and drainage is performed during transportation so as to provide enough anti-shaking torque; the berthing side of each floating box is connected with a ship side of the floating ship, a fixing frame is arranged on the upper portion of each floating box, and the upper end of each fixing frame is connected with the deck of the floating ship. Rails are arranged on the floating ship, and the rails are arranged in the bow and stern directions of the floating ship. According to the floating type installation structure of the offshore converter station, the anti-swing floating bodies can provide certain anti-swing torque during transportation, so that the transverse stability of the floating ship is greatly improved, the rolling amplitude is greatly reduced, and the safety of an upper structure and electrical equipment during transportation is guaranteed.

Description

Technical field [0001] The present invention relates to a float-type structure and method for mounting offshore converter station for offshore wind Field. Background technique [0002] Wind power is a new kind of clean energy, use of marine wind energy, offshore wind power development is the development trend of wind power. In recent years, my country's rapid development of offshore wind power by the end of 2018, my country's total offshore wind power installed capacity has reached 3.6 million kilowatts, and millions of kilowatts of offshore wind power project under construction. [0003] With the large-scale development of offshore wind power, offshore wind power output increasingly important, accounting for its investment is also growing. Offshore wind power output generally output AC, DC two schemes, requires the construction of offshore booster station needs an AC requires the construction of offshore output DC converter station. Offshore converter station generally planar si...
