Based in the UK, Renewable Oil Services (ROS) is the region’s largest supplier of oil products and oil exchange services for the wind turbine industry, serving both onshore and offshore markets across the UK and Ireland. Known for precision, reliability, and technical excellence, ROS ensures wind turbines perform at their best throughout their lifecycle.

Now part of the Muehlhan Wind Service family, ROS continues to operate under its own name and management team, delivering specialized services that strengthen MWS’s comprehensive capabilities in turbine maintenance and lifecycle support.

ROS brings more than a decade of experience in gearbox and hydraulic oil exchanges, flushing services, and environmentally responsible oil management — all performed with a strong focus on safety, quality, and sustainability. In 2013, ROS became the first company in the world to carry out a vessel-mounted oil exchange on an offshore wind turbine, using a pumping system designed and built entirely in-house. ROS also operates with specialized trucks and offshore units equipped with in-house developed heating and filtration systems. These allow the team to pre-heat and filter new oil before pumping it through up to 180-meter hoses to the turbine nacelle and gearbox, ensuring efficient, contamination-free exchanges even in demanding environments.

ROS’s commitment to sustainability has been formally recognized. The company won the Ayrshire Chamber of Commerce’s ‘Driving Sustainability’ award in 2024 and 2025, affirming its leadership in the region for environmental performance and innovation.

As part of MWS, Renewable Oil Services continues to raise the standard for precision oil management, driving reliability, sustainability, and performance in wind energy.
