Cement grouting is an effective alternative to reconstruction of the foundation

Wind towers founded on spread footings may settle as a result of loose bearing soils either not identified during the preconstruction geotechnical exploration or...

Proper lubrication and contaminant control are critical in order to attain long gearbox service...

In conducting end of warranty inspections, we typically find a number of turbine gearboxes with internal gear damage that occurred over a relatively short...

Turbine icing is an increasing challenge to the economics of wind energy

The northeastern and mid-Atlantic U.S. is an attractive region for future wind park developments due to good wind resources, state incentives, and ease to...

Why should a developer assess strategic logistics considerations before final OEM selection?

For most wind farm projects, site developers outsource the delivery of components to the OEM. The price structure and delivery terms for this service...

Chemical grouting is an effective alternative to complete reconstruction of the foundation system

Wind towers founded on spread footings may settle as a result of loose bearing soils either not identified during the preconstruction geotechnical exploration or...

Protecting turbine cables is vital

One of the most common findings from a wind turbine inspection is broken cable ties, which results in abrasion to cable insulation, and perhaps...
