PTC or not, the wind industry is an ever-changing landscape for post-warranty maintenance

PTC or not, the wind industry is an ever-changing landscape for post-warranty maintenance. Taking a thorough look at the project before the end of warranty is always an important element to consider before the turbines trade hands.

As we round out 2012, it is remarkable to know that the greatest number of wind turbines ever in a single year, some 30,000, will have reached their end of warranty over the past 12 months. Regardless of whether the PTC is renewed or not, the project operator’s focus on optimizing O&M costs and improving […]

Excess vortex-induced vibrations wreak havoc on offshore wind turbine mooring lines

Previously, I discussed the fluid-structure interaction problems in floating offshore wind turbines. One of these problems is vortex-induced vibrations of mooring lines. In an offshore wind platform, the mooring lines are used to provide a sufficiently stable platform for the wind turbine. The interaction of the mooring line and the fluid flow around it can […]
