Function
Maintenance activities ensure the ongoing operational integrity of the wind turbines and associated balance of plant in response to faults, either proactively or reactively.
What it costs
About £20 million per annum for a 450 MW floating offshore wind farm.
Who supplies them
Maintenance activities are provided by a combination of the owner’s in-house resources, wind turbine suppliers and third-party service providers.
Key facts
There is considerable focus in the industry on optimising maintenance activities to reduce OPEX whilst also achieving the targeted levels of availability and reliability. This optimisation is best achieved by taking a lifetime view of the project economics, focussing on the LCOE. Operational management teams consider the whole operational system to achieve this.
