What Are Transient Loads, and How Do I Reduce the Effect On My Turbines?

In the wind industry today, there is more discussion than ever on loads in the drivetrain of turbines. A significant amount of work has been done over the past few years to show that transient loads, particularly transient torque reversal loads, are occurring more often than expected. NREL’s Gearbox Reliability Collaborative has discussed transients and […]

Is the Tide Finally Turning for Offshore Wind in the United States?

For more than a decade, offshore wind has been viewed as the next big thing in the U.S. energy mix. In Europe, billions of euros have been invested in 82 offshore wind farms — 10.4 GW of capacity, according to the European Wind Energy Association (EWEA) — roughly equivalent to the power production of 10 […]

Reaching New Heights

Could wind drones be the next evolution in wind power generation?

Drones will eventually be “as ubiquitous as pigeons,” London-based futurist Liam Young recently predicted. They are omnipresent already. Only five years ago drones belonged to the realm of the military, unaffordable for anyone else. Today, they are for hobbyists and even kids. Drones arrived in our lives and conquered the extreme ends of the market […]

Manufacturing Versus Remanufacturing: A Technician’s Perspective

Not all wind energy students plan to climb towers for a living. Fortunately, there are plenty of career opportunities for Ecotech Institute grads that don’t require them to leave the safety and security of terra firma. Two options that I discuss at length in the classroom are jobs in manufacturing of turbines and components as […]

Responding To Student Concerns About Wind vs. Cheap Oil

If you read my article last month, you may have enjoyed some of the naïve but entertaining questions prospective wind energy students ask the wind instructors during campus tours. As they approach graduation, their questions take on a more serious tone. One recurring theme as of late is related to falling oil prices. “Will cheap […]

Improving LCOE By Training The Human Assets

Holistic operations knowledge and ongoing training are key factors in bolstering efficiency

When I worked for large international wind companies, like GE and Nordex, I saw entire infrastructures — engineering, EHS management, spare parts warehousing, SAP specialist, IT support, O&M schedulers, remote monitoring, process writers, etc. — created to support the operation. However, very few people actually climbed the turbines to do maintenance and troubleshooting.  I have […]

Validation Of Journal Bearings For Use In Wind Turbine Gearboxes

Maximum reliability and low life-cycle costs are the decisive key factors for systems operators in nearly all areas of industry, including the windpower industry.

That also applies to gearboxes in windpower turbines functioning as the main constituent of the drive train. Journal bearings now offer a technology that is already being used successfully in other areas of industry and is further enhancing the availability of windpower systems. Experience shows that journal bearings make a very good alternative to the […]

Predictive Maintenance Methodology Streamlines Operations

Condition monitoring approach reduces downtime while providing cost savings

Operations and maintenance (O&M) of wind turbines is estimated at 21 to 24 percent of the total cost of energy from wind. As turbines are built larger, the capital-expenditure component of the cost of energy from wind drops, but there is still room to reduce the cost of O&M. Too often maintenance is carried out […]
