Wind Turbine Operation & Maintenance

At Castrol, we believe renewable energy will form a key part of a sustainable future – and we’re proud to play a crucial role.

With rapid changes in wind-energy technology, our Liquid Engineers know turbines have grown in power, placing higher demands on turbine lubrication. We know the challenges of gearbox and bearing lubrication (due to gearbox complexities and high mechanical loads) and the tougher applications involved in wind turbine duty, and these are a common cause of costly downtime. You need truly specialist solutions to combat these tough conditions. 

Our Liquid Engineers recognize the need to reduce dependence on fossil fuels. To extend the cost-competitiveness of wind energy against conventional energy sources, the reliable operation of all equipment has never been more important. Our wind-turbine-lubrication solutions have been expertly engineered to help you boost the efficiency and reliability of your equipment, making wind energy more cost-competitive and viable.

We use our industry and proven applications expertise with our advanced product ranges to deliver solutions that provide reliable and economical performance. Working with key component manufacturers, we can understand and deliver on the technical demands of the industry, helping you pioneer innovative technology for the future.

For your wind turbine operations, our Liquid Engineers recommend the following products:

Operations

Recommended product

Main gears and auxiliary

Our complete range of high-performance gear oils has been developed to protect and maximize the performance of current and next-generation wind-turbine gearboxes. Our teams have tested them in field-trial applications and Castrol development laboratories, and they have been subjected to extreme conditions by an independent tribology laboratory to help provide sustainable performance for your operations.

CASTROL OPTIGEAR SYNTHETIC X

Castrol’s industry-leading product designed for use with industrial gears operating with wide-temperature fluctuations and under high loads; sliding and rolling bearings, wind turbines, conveyor belts, crane control gears, lifts, rolling mills and more. Best-in-class surface protection and friction reduction.

CASTROL OPTIGEAR SYNTHETIC CT

Purpose-developed alongside one of the world’s leading turbine manufacturers, this product meets or exceeds the latest major OEM specifications.

Main bearing

A complete range of greases and high-performance oils for lubricating highly loaded rolling element bearings and tailor-made for the operating conditions encountered in the main rotor bearing. These can help ensure sustained and reliable lubrication.

CASTROL TRIBOL 3020/1000

Castrol Tribol 3020/1000 with plastic deformation technology helps extend the life of wind-turbine main bearings. 

CASTROL OPTITEMP SW 1

A lithium-based grease with the potential for energy savings and reducing operating temperatures. 

Pitch adjustment

Specialist greases that lubricate pitch-adjustment bearings in tough operating conditions (such as high loads in high wind speeds) and protect from wear caused by oscillations from varying wind speeds. 

CASTROL OPTITEMP SW 1

A lithium-based grease with the potential for energy savings and reducing operating temperatures.

Yaw bearing

The yaw bearing must be able to handle high loads and provide smooth rotation characteristics for the nacelle under all weather conditions during wind-turbine operation. It requires corrosion- and wear-resistant lubrication and must be long-lasting. Our greases have been used for many years both on onshore and offshore turbines.

CASTROL OPTITEMP SW 1

A lithium-based grease with the potential for energy savings and reduced operating temperatures.

Hydraulic systems

A comprehensive range of hydraulic oils designed for use in a range of temperatures and extreme climates during wind-turbine operations. Our Liquid Engineers are innovative when it comes to formulating oils from raw materials, and these solutions are then rigorously tested in both laboratory and manufacturing conditions in close collaboration with the manufacturers of leading hydraulic systems and wind turbines. Castrol also has a range of superior biodegradation* oils for use in environmentally sensitive areas.

* Superior biodegradation compared with conventional mineral-based lubricants.
