Dealing with the gearbox

Ideally, gearboxes would run forever with no downtime, but repairs are required in the real world. Ask the following questions for improved outcomes.

As you know, the gearbox is a critical component of the wind turbine drivetrain. Should you encounter a problem with this unit, what should you do? Who can handle the repairs, what will they cost, and how long will it be down? All are valid questions, but one of the most important is whether the […]

Foundation problems and their solutions

No structure can remain standing without a solid foundation. Read on for a primer in foundation types and ground-preparation techniques.

Foundations have been a critical aspect of wind turbine tower design since the earliest days of the industry. Many early towers experienced foundation problems since the unique loading associated with these structures was not yet fully understood. As towers become taller, efficient foundation design is an increasingly significant component of the overall profitability of wind […]
