Challenging the applicability of ISO standarts and design assumptions for wind turbine main bearings
Dr. Edward Hart -
Royal Commission Brunel Research Fellow,
Wind Energy and Control Centre, UK

Bearings on floating wind turbines
• Can we use bearings designed for onshore turbines on floating ones?
• What is the effect of floating sub-structure on bearings inside the drivetrain?
• What would be the effect on main bearings?
12:50 pm - 1:30 pm
A strategic dive into the industry’s lack of an international standard about grease cleanliness during operation for avoidance of hard particles lamination
Remi Stein -
Wind Turbine key expert,
ENGIE, France
Dr. Edward Hart - Royal Commission Brunel Research Fellow, Wind Energy and Control Centre, UK
• How hard particles lamination is detrimental to MBs
• What size of hard particle will initiate lamination for MBs in the highly variable operating conditions in wind?
• Particles nature and size characterization
• Harmonization of sampling port/sampling procedure, analyses and interpretation
• Is wear particles in grease a reliable methodology?
• Can wear particles in grease early identification allow mitigation, life “extension” and failure avoidance?
1:30 pm - 3:00 pm
Networking Lunch
