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
