Offshore availability for wind turbines with a hydraulic drive train [PDF]

open access: yes3rd Renewable Power Generation Conference (RPG 2014), 2014
Hydraulic drive trains for wind turbines are under development by a number of different companies; at least one hydraulic drive train is in the final stages of development by a leading wind turbine manufacturer. Hydraulic drive trains have a number of advantages such as redundancy, modularity, compactness and track record in other industries. Currently
