ExxonMobil Protects Wind Turbines with Advanced Lubricants ExxonMobil lubricants help support more diverse energy portfolio for power generation

 Mobilgear SHC XMP 320 helps reduce maintenance costs for wind energy industry  Formulated to deliver exceptional protection for key components under extreme conditions  Selected as the initial-fill oil for majority of world's top wind turbine builders

HUSUM, GERMANY -- ExxonMobil‘s Mobil SHC-branded synthetic gear oil is now being used to protect more than 30,000 wind turbine gearboxes worldwide, demonstrating how its lubricants are helping the wind energy industry become more cost competitive worldwide.

As the wind turbine market has experienced rapid growth around the world over the last decade, ExxonMobil’s Mobilgear SHC XMP 320 continues to be a popular lubricant choice for wind turbine operators. Mobilgear SHC XMP 320 is the initial-fill gear oil of choice for the majority of the world's top wind turbine builders.

“Although it starts from a small base relative to conventional sources, we expect electricity generated by wind to grow 12 percent a year through 2030,” said Mike Hawkins, global brand manager for ExxonMobil Lubricants & Petroleum Specialties Company. “Our wind lubricant technology helps support this growing industry by reducing maintenance requirements and ultimately lowering costs.”

Mobilgear SHC XMP 320 is an ideal lubricant for gearboxes used to power wind turbines because it exceeds the performance of conventional, mineral-based oils by extending the interval between oil changes from 18 months to three years or more.

For wind turbine operators, maximising equipment performance and durability is essential. News Release

“In an industry that relies on the performance of turbines, which may stand up to 400 feet high in the air, often in remote environments, there is no such thing as a simple oil change or routine maintenance,” said Hawkins.

“That’s why our Mobil SHC branded lubricants, like Mobilgear SHC XMP 320, are valued by wind turbine operators around the world. They are expertly formulated to help reduce maintenance costs, extend oil drain intervals and deliver exceptional protection for key components, even under the extreme weather and load conditions that wind turbines face every day.”

With its proprietary balanced additive system, Mobilgear SHC XMP 320 offers potential for enhanced energy efficiency and protection against conventional wear modes, such as scuffing and micropitting. The high-performance synthetic gearbox oil offers exceptional oxidation resistance and excellent low temperature fluidity, which can help reduce unscheduled downtime and lower maintenance costs.

In addition to Mobilgear SHC XMP 320, ExxonMobil offers a wide range of lubricants that are formulated to deliver exceptional protection for all parts of a wind turbine, including greases to lubricate bearings and hydraulic oils that help pitch rotor blades.
