Wind turbines consist of nacelle, hub, blades, towers, and control systems. Turbines can be onshore or offshore with different foundation structures
Regular cleaning during operation prevents contamination and extends overhaul intervals. Compressor cleaning should be done with water injection at full speed. Turbine cleaning requires boost pressure above 0.3 bar and exhaust temperature below 430°C. Particle accumulation below gear oil pump is harmless and can grow to 1/4 cm³
Maintenance task lists are ordered activities for constant maintenance. Used in both planned and ongoing maintenance processes. Three types exist: General, Functional Location, and Equipment. Technical items run maintenance according to scheduled times
