This highly specialized task is performed by trained technicians who use large cranes to carefully detach the massive blades from the turbine's hub, hundreds of feet in the air. Once on the ground, the blades, which can be longer than a football field, must be prepared for.

The width, height, and width of wind turbine blades usually range from 18 to 107 meters (59 to 351 feet) long, depending on the use of electricity produced. 4 meters length of the blades is the best compromise between swept area, energy production, weight, and loads.

The average blade length of a typical onshore wind turbine is about 165 feet (50 meters), but there is a trend towards taller turbines, particularly offshore, where blades can span up to 260-290 feet (80-90 meters). Wind turbine blade technology has evolved dramatically over the.
