Understanding the importance of field tiles and identifying ways to mitigate issues

Understanding the importance of field tiles and identifying ways to mitigate issues will help to improve landowner relations and lower overall construction costs.

Nothing is simple when dealing with tiling issues on wind facilities in certain portions of farm country. They are almost never surface located as part of a typical “one call” or underground utility location service. Most, if not all, of the tiles are poorly mapped and cannot be identified until they are encountered in the […]

Insights on how to safeguard personnel during the long winter months

In this conclusion of a two-part series, the author continues his discussion of preseason winter preparations, providing insights on how to safeguard personnel during the long winter months.

In the October installment of this column we discussed various ways to prepare the wind turbine for winter operations. We continue our conversation by addressing the safety risks related to cold weather and how advance planning, and training, can avoid cold weather related injuries to the service team. Most technicians know how standing for long […]

Conversion factors are needed in order to navigate the relative interpretation of time-averaged extreme wind conditions

In order to properly navigate the relative interpretation of time-averaged extreme wind conditions in various standards and data sources, conversion factors are needed.

The U.S. coastal environment offers challenges to widespread offshore wind development compared to projects installed in Europe. The prevalence of hurricanes along the Eastern seaboard and the Gulf of Mexico will require additional considerations as the U.S. defines its design standards. These issues are being addressed by several groups, such as a recent National Academies […]

Logistics planning requires factoring in the interaction between weather and the terrain

Logistics planning requires factoring in the interaction between weather and the terrain to be transversed — taking a 3D rather than a 2D approach.

As the seventh consecutive day of rain was drenching me in the middle of a project, causing delays and running up costs, I thought of a line by Longfellow—“The best thing one can do when it’s raining is to let it rain.” No matter how well you plan, Mother Nature can and will push back. […]
