Turbine reliability a crucial part of success

In order to increase reliability and service life, there are a number of areas wind turbine owners can address. Here’s what you need to know.

As the U.S. wind industry begins a trend of increased post-warranty operations, owners are taking aim at turbine reliability as a critical aspect in the success of a wind project. Inarguably, poor reliability results in increased O&M costs, accompanied by a reduction in availability and increased downtime. Modern turbines unfortunately have a relatively short operating […]

A look at turbine noise

Research into aero-acoustic properties will result in both the improved efficiency of wind turbines and increased siting opportunities, as the associated noise is decreased.

As the industry continues to grow and develop and with wind turbines continuing to be deployed across the nation, the likelihood of wind farms being sited near inhabited areas increases. An important constraint on wind turbine placement arises due to the consideration of wind turbine noise. As a key design metric, the noise generated by […]

Harnessing the power of offshore wind

Offshore energy production is on the rise around the world, which will present logistical challenges requiring knowledgeable partners to overcome.

Offshore energy production is gaining traction as consumption of electricity from conventional sources declines and renewable sources continue to grow. Countries and companies alike are gaining confidence in this relatively new opportunity for renewable power. Offshore wind velocity is generally higher and the wind more consistent, compared to onshore winds. That can provide greater capacity, […]

The technology and concept behind soil mixing

Soil mixing is an economical and efficient alternative to deep foundations for challenging sites, particularly for wind turbine foundation applications.

Soil mixing techniques are used to mechanically blend soils in place with cementitious material to improve the soil engineering properties such as strength and compressibility. This installment discusses the soil mixing concept and technology. Oftentimes the engineer has no influence over the location of the wind energy site and has to design the foundation around […]
