Maintaining the wind turbine revolution
In an informal survey of 75 wind farm operators in the United States conducted by Frontier Pro Services, many respondents indicated they had fallen behind on scheduled preventive maintenance such as oil changes and gearbox lubrication because of a shortage of qualified technicians. According to Frontier, the survey found many wind farm operations and maintenance teams are so resource-constrained that they can barely keep up with unscheduled breakdown repairs to wind turbines. ..."Damage caused by worn out or compromised gear oil can be irreparable," said Frontier Pro Services lead technical advisor Jack Wallace, who has been servicing wind turbines for more than 20 years. "You can really see that it makes no sense to put off needed oil changes."

The fastest-growing segment of the power generation industry is wind, which is on track to expand by over 45 percent in the United States this year, says the American Wind Energy Association. But equipment reliability remains a stumbling block to growth, as operators struggle with ensuring that critical components - such as gearboxes and bearings - remain properly lubricated and maintained.
Blade tips on modern turbines can reach as high as a 40-story building, and their columns may be anchored high on a mountaintop or offshore in the ocean. Even routine maintenance takes extra effort - and may simply... [continue via Web link]
