Operation and maintenance

Scientific aspects of the result and innovative features:
A Probabilistic O&M Cost Optimisation model is presented, with which the operation and maintenance strategy of offshore windfarms can be improved. Basis for the application of this model is an extensive analysis of the fault detection and repair cycle offshore. A calculation model has been added. A generic database has been proposed in which O&M information of offshore windfarms can be gathered, processed and presented. The database should be organised, used and maintained by the windfarm owners. An international approach of countries around the North Sea seems most yielding.

Social and commercial aspects of the result:
There has been an immediate need for the project. Currently and over the next few years, the expansion in offshore wind energy, especially in Europe, accelerates and at project start there were no thorough and coherent guidelines for the design of offshore wind power plants. The existing offshore standards are not suitable to cover the offshore wind energy technology.

A combination of these offshore standards and the existing onshore wind energy standards is a very complex process and significant technology gaps exist. One of the major tasks of the project has been the attempt to combine the practices of wind turbines engineering and offshore engineering. According to the main results stated in the executive summary the project has succeeded in this, and thus it is the view of the project partners that the project outcome has aided a development with the potential of preventing erroneous decision-making on large investments in Europe on a technical weak basis.

Potential applications for and End-users of the result:
End-users are designers of offshore wind turbines i.e. manufactures, certifying bodies, and owners and operators of offshore wind farms.
