Cement grouting is an effective alternative to reconstruction of the foundation

A proven technique for stopping or reducing settlement, cement grouting is an effective, cost-efficient alternative to complete 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 remaining after inadequate subgrade preparation. Loose granular soils may also be susceptible to liquefaction during a seismic event, which may result in excessive settlement or complete foundation failure. When wind towers […]

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

Proper lubrication and contaminant control are critical in order to attain long gearbox service life, both during and after the warranty period.

In conducting end of warranty inspections, we typically find a number of turbine gearboxes with internal gear damage that occurred over a relatively short period of time. While these issues have materialized largely unnoticed by the project owner up to the final turnover inspection, the affect of such irreversible conditions will gravely impact the performance […]

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

Turbine icing is an increasing challenge to the economics of wind energy in cold climates. Read on to learn how it happens, what it causes, and how it can be addressed.

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 grid connection in the vicinity of major populated areas. The associated colder climate conditions sound promising at first sight because of possibly strong winds and higher air density, e.g. air at […]

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

Why should a developer assess strategic logistics considerations before final OEM selection? Because you need to know what you’re paying for!

For most wind farm projects, site developers outsource the delivery of components to the OEM. The price structure and delivery terms for this service vary by project, but contractually it is the responsibility of the OEM to resolve the many complex considerations involving wind component transportation. So why is it critical for the developer to […]
