Wind turbines have the potential to generate enough power to meet growing needs for electricity, diversify sources of energy, and reduce consumption of water and emission of pollutants such as carbon dioxide. Barriers to widespread acceptance of wind turbines include their reliability and costs for operation and maintenance (O&M) of the equipment relative to alternative means of power generation. Lubricant-related failure, unexpected down time, and expensive unscheduled maintenance are problematic, especially for wind turbines in offshore locations. According to Wind Energy Update’s 2011 Operation and Management Report[1], as much as 66% of the O&M costs for some offshore wind turbines may be related to unplanned maintenance events. The Report notes that some wind turbine gearboxes are warrantied for 20 years but fail within 8 years. Gearboxes are critical components of wind turbines.[2] A research and development initiative to improve gearbox reliability, headed by the National Renewable Energy Laboratory (NREL), seeks to improve the design process for wind turbine gearboxes.[3] In addition, there is a growing need to efficiently manage the reliable operation and economical maintenance of in- service wind turbines now and in the future.[2-4]

Oil analysis is a cornerstone of condition-based monitoring and reliability engineering for critical mechanical devices in manufacturing, aviation, and countless other applications[5,6]. Oil analysis refers to the collection and evaluation of samples of in-service lubricants in order to assess the condition of the oil and machinery, and inform decisions about their maintenance. In addition, oil analysis data can serve as a log of historical information about the condition of the fluid and equipment. Work is underway to develop methods to apply existing test methods[7,8] for oil analysis, and invent new ones, for wind turbines. This article recommends some useful oil analysis tests for routine evaluation of in-service gear oils in wind turbines, and some additional tests that can provide further insight as needed.
