LONDON — Over the past two decades, wind turbine manufacturers, gear designers, bearing manufacturers, consultants and lubrication engineers have been working together to improve load prediction, design, fabrication and operation. This collaboration resulted in an internationally recognised wind turbine gearbox design standard (International Organization for Standardization 2005). But, despite this, most systems still require significant repair or overhaul well before their intended life is reached. Manufacturers continue to modify and redesign existing turbines and it is difficult to validate the modifications fast enough to prevent multiple units with unsatisfactory ‘solutions’ being deployed.
