Two-Blade Turbines the Future of Offshore Wind Energy? – The Maritime Executive

The benefits of two-bladed turbines include cheaper construction because they require fewer less material to construct and are easier to install. Industry leaders estimate that two-bladed turbines could cost about 20 percent less to construct and install while still generating the same amount of power as three-bladed turbines.

Removing the third blade makes the rotor lighter and allows engineers to place the rotor on the downside of the tower. In addition, two-bladed rotors are often easier to install than three-bladed turbines which must be constructed on-site. Because they often weigh up to 40 tons less than conventional rotors, two-bladed rotors can be built onshore and transported to its designated location on a ship because it is light enough to be lifted onto the tower.
