End of warranty Blade Inspections

Offshore Painting Services recommend that our clients wind turbine blades should be inspected by our expert and accredited blade technicians 6 months prior to expiration of warranty. This small cost of mobilising a team of blade repair and blade inspection technicians can save our clients the costly process of blade repairs once the blade warranty has expired.



Post Warranty Blade Inspections

Offshore Painting Services recommend that our clients perform blade inspections every 2 years. If any defects have been noticed we suggest inspections on a more regular basis if blade repairs are not an option at the time. Offshore Painting Services can arrange a fixed blade inspection price for clients wishing to opt for our 2 yearly inspection option so budgets can be planned around this important maintenance process.
