Abstract
A method for performing maintenance on an outer surface of at least one wind turbine part, such as a tower (), a nacelle () or a wind turbine blade (), of an offshore wind turbine () is disclosed. An access system () is transported to a site of the offshore wind turbine (), and the access system () is transferred to a transition platform () at a lower part of the offshore wind turbine (), while operating the offshore wind turbine () in accordance with a normal operating mode. Normal operation of the offshore wind turbine () is then stopped, and maintenance is performed on an outer surface of at least one wind turbine part () of the offshore wind turbine (), using the access system (). When the maintenance has been completed, normal operation of the offshore wind turbine () is restarted in accordance with a normal operating mode. Normal operation of the offshore wind turbine () is only stopped while the actual maintenance takes place. Thereby the loss in power production is minimised.
