Inside the nacelle of a wind turbine.

The past, present, and future of up-tower turbine repairs

Not too many years ago, working up-tower on a wind turbine was challenging if not impossible. Nacelles weren’t designed for easy access. If anything needed fixing inside, whether it was a high-speed shaft or an intermediate bearing, down came the gearbox. What Mark Eagle, General Manager of Moventas, remembers most about those early days in

Composite manufacturer MARKOS has been EN 1090 certified

MARKOS, a composite manufacturer, has been EN 1090 certified by TÜV SÜD. The main production activity of MARKOS company is glass-reinforced plastic production of wind turbine nacelles, hub covers, as well as technical boats and other products. MARKOS also manufactures steel elements designed for wind turbine nacelles and steel or aluminum structures for other sectors.

Turbine Manufacturing

How is a nacelle manufactured?

Manufacturing today’s wind turbine can involve millions of dollars and hundreds of people. To better understand what comes from the years of research and development to the final days of production, let’s tour a modern turbine production facility. The nacelle is the part of the turbine that houses the components that transform the wind’s kinetic

GE expands Brazil wind turbine production facility

GE has announced the expansion of its Campinas, São Paulo, manufacturing facility and the creation of 35 new skilled jobs. Co-located with Brazilian machinery manufacturer and GE Group subsidiary GEVISA, the facility will produce nacelles for GE’s 1.7-100 and 1.85-82.5 wind turbines. The machine head is a primary component of a wind turbine and houses

The laser-cladding process (at work on a truck axel), can repair wind-turbine components, such as damaged or worn shafts. The process provides a metallurgical bond that fuses to the shaft surface so well it performs like new.

Laser cladding to make worn main shafts like new

A laser-cladding process developed by Caterpillar Inc. to repair wear and damage to large axels on mining trucks is applicable to worn or damaged main shafts of wind turbines. At a recent O&M Summit, Kristin Schipull, a metallurgist with Caterpillar (www.cat.com), showed how the process works and reported that repaired axels match the performance of

Nordex adjusts structures to local US market situation

Nordex SE announced today that the company will cease nacelle production at its Jonesboro, Arkansas facility after it completes the orders in its current pipeline. The decision was driven by the wind industry’s global overcapacity and the continued uncertainty and instability of the US market. The decision will not impact the current year’s business performance,
