Steel Structure Offshore Wind Power Factory

Steel structure offshore wind power factory buildings refer to heavy industrial factories specifically designed for the manufacturing of offshore wind power equipment. Their main structure is made of steel, and they are usually located at coastal ports or docks to meet the production, assembly and transportation needs of extremely large and heavy components.

Our Chinese factory has provided steel structure solutions for multiple offshore wind power projects and is one of the high-quality steel structure suppliers in China.

Structural form

● Heavy steel truss structure: This is the most common structural form.

● Heavy portal frame: Suitable for general manufacturing or assembly workshops.

● lSteel truss and net frame structures: Used for extremely large-span or specialized-function factories.

Corrosion resistance and wind resistance design

● Corrosion protection system: Since these industrial buildings are constructed near the ocean, the surrounding environment is relatively humid and there are more extreme weather conditions. The surface treatment of steel adopts a heavy corrosion protection coating system.

● Wind resistance: The building itself needs to be designed according to the wind load standards of 50 or 100 years once in a century in coastal areas to ensure structural safety in extreme weather conditions.

The structural components of the product

Main structure

● Usually, lattice steel columns are adopted. For Steel structure offshore wind power factory with large height and heavy crane tonnage, lattice steel columns have greater bending strength and can support the weight of the column crane.

Crane beam system

● Crane beams usually use high-strength welded solid-web I-beams, with yield strength often reaching 355Pa or 390Pa.

Support system

● Inter-column supports can be made of H-shaped steel, angle steel and round tubes, usually in X-shaped form.

● Horizontal supports will be arranged on the roof to transfer the horizontal force of the roof.

● The system is usually arranged at the top of the columns, aiming to protect the stability of the forces between the steel frames.

Enclosure structure

● Purlins usually use high-frequency welded H-shaped steel or C-shaped steel.

● Wall beams are mostly H-shaped steel or large C-shaped steel, and are connected by sliding to adapt to the lateral deformation of the main structure under wind load or temperature effects.

Product case

The Lishan large-megawatt offshore wind power project, which was jointly participated by EIHE Steel Structure, is the largest single-offshore wind power project with a price parity in China and the largest offshore wind power cluster in northern China. It is located in the southern sea area of Lishan City, Weihai City, Shandong Province. The entire project is divided into two independent sites, U1 and U2, with a total installed capacity of 150 megawatts (1.5GW).
