. Oleum Ventus Renewables is a unique wind turbine service provider. Unlike most service companies, we focus on only two aspects of wind turbine services, nothing else. Those two aspects are Gearbox Oil changes and Turbine Torque and Tensioning. By focusing on these two areas only, we're able to refining the processes and perfect the service quality. An additional unique aspect is that we charge by the turbine, not by the hourly rate. From a customer's P&L aspect,this allows them to understand the exact costs and budget accordingly, reducing their overall operating expenses.
