How often are wind turbine blades inspected?
How often are wind turbine blades inspected?
every year
Based on a review of onshore and offshore wind farm regulations, standards and inspection practices a US government report published in 2015 (“Offshore Wind Energy Inspection Procedure Assessment”) recommended that the wind blades should be inspected every year.
How are turbine blades inspected?
A typical internal wind turbine blade inspection requires an inspector to physically enter the blade. While inside, the inspector collects visual data on the condition of the turbine’s blades. Each blade has two or more chambers separated by a web.
How often does a wind turbine blade need to be replaced?
about 25 to 30 years
Wind turbine blades last an average of about 25 to 30 years. When they are replaced, the old blades become a challenge, from transporting them out of the field to finding a place to store the blades, which can be longer than a Boeing 747 wing.
How long does it take to inspect a wind turbine?
The wind turbine inspection was completed within two hours (three blades were inspected in only 45 minutes) under ideal light and weather conditions.
How much do wind turbine mechanics make?
The median annual wage for wind turbine technicians was $56,230 in May 2020. The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less. The lowest 10 percent earned less than $40,490, and the highest 10 percent earned more than $83,580.
How much does it cost to inspect a wind turbine?
According to a recent report by consulting firm PwC, “a standard wind turbine inspection currently costs around $1,500 per tower; performing the same inspection using a drone cuts the cost by around 50 percent.”
