Contract Manufacturing for Onshore and Offshore Wind Energy
Flanges, rings, hub attachment parts and mountings for onshore and offshore turbines
Wind turbines operate day and night under changing loads, and offshore also in salt-laden air. Their components must therefore be manufactured accurately and documented properly. MWA – Mechanische Werkstätten Anhalt GmbH in Halberstadt manufactures components for turbines on land (onshore) and at sea (offshore) to drawing.
We produce new parts for turbine construction as well as spare parts for maintenance and repair, from single part to series.

Which parts do we manufacture for wind turbines?
- Flanges and rings
- Attachment parts for the hub and blade connection
- Mountings, brackets and adapter plates
- Parts for gearboxes, yaw and pitch drives to drawing
- Shafts, bushings and pins
- Components for the nacelle, tower and foundation connection
- Spare parts for maintenance and repair
What is the difference between onshore and offshore?
Onshore turbines stand on land, offshore turbines at sea. Offshore adds salt, moisture and hard-to-reach locations. That is why corrosion protection, material selection and the reliability of every component play an even greater role there, since replacing a part at sea is costly and complex.
For manufacturing, this means that material, dimensional accuracy and documentation are precisely defined before the order. On request, we arrange coatings and surface treatments through our network.
Which materials are typical?
Common materials are structural steel and quenched and tempered steel for flanges, rings and load-bearing parts, ductile cast iron (spheroidal graphite) for housings and hubs, bronze for plain bearings, and stainless steel for parts exposed to high corrosion. The material is verified with a certificate according to EN 10204.

How large can the parts be?
We machine small to medium-sized parts up to Ø 2,500 mm, 6,000 mm length, 3,000 mm height and 25 t. Flanges and rings are turned, hole patterns and connecting surfaces are milled or machined on the boring mill. For even larger parts, we broker the order through our manufacturing network.

Why are spare parts so important in wind energy?
Every turbine standstill costs yield. If a part is no longer available from the manufacturer, or only with a long lead time, a manufacturer working to drawing or sample can be the solution. We agree functional dimensions, material and inspection characteristics with you before production.
