Weather Measurements in the North Sea. TNO conducted detailed measurements of precipitation in the North Sea for a year. Analysis of this data (pdf) revealed that about 30% of the annual erosion ...

"We already knew that heavy rain significantly affects the rotating turbine blades, but the fact that 30% of the erosion damage occurs in such a short time was a new insight," says Harald. When the ...

After several years of service under harsh weather conditions, the rotor blades of offshore wind parks are subjected to degradation and surface erosion, releasing sizeable quantities of particle ...

“Rain erosion is an already serious and worsening issue with the longer rotor blades generating tip speeds of over 380km per hour,” Martin Huus Bjerge explained.

“After 82,810 hours of wet compression across four turbines, there are no reports of any erosion or any issues with compressor blade damage,” said Garcia. U.S. users report similar findings.

A novel wind turbine blade protection coating promises to “significantly reduce” potential damage from lightning strikes.
