Offsore Wind Smart Drivetrain Lubrication Project
Smart Lubrication Drivetrain
Huge mechanical machine
Important moving parts
Smart Lubrication Drivetrain
Important mechanical moving parts:
• Main power train • Bearings• Gearbox
• Pitch power train• Motor• Planetary Gear Box • Gear Rings
• Yaw power train• Motor• Planetairy Gear Box • Gear rings
Smart Lubrication Drivetrain
• Downtime mainly caused by
• Gearbox
• Main bearings
• Yaw, and pitch system
• Failure cause:
Overload wear issues
Underload extensive slip of moving parts

Smart Lubrication Drivetrain
• Necessary – developing smart lubrication – drive train
• Autonomous system – zero downtime – zero maintenance – avoid people at sea
• Autonomous technology – sensors Data Information
• Take action only when needed
Smart Lubrication Drivetrain
• Oil degradation and wear particles indicates that a gearbox has a problem
• Vibrations indicates that a (main) bearing has a problem
• Warning only actions when abnormal conditions
• Combining data from multiple sensors

Lubricants itself: Automotive/Conventional/High Performance
• Conventional lubricants–meet specifications–minimum requirements
• High performance lubricants are formulated on maximum requirements
• Conventional lubricants 1-3% additives
• High perfomance lubricants
• maximum 30% additives
• HQ base oils
• Longer lifetime – less wear – smarter lubrication

Smarter lubrication
• Friction reduction
• Higher effciency –power curve improvement
• Longer lifetime of lubricant
• Less wear
• Longer lifetime of rotating parts
• No manual regreasing
• Less maintenance
• Less/no people at sea
