Lumping of fatigue loads

Scientific aspects of the result:
At the project outset, there were many uncertainties regarding the offshore environment. Amongst other factors, the effects of waves, wind/wave misalignment and tides, on fatigue and extreme turbine loading were not well understood. Also the effect of the varying the offshore wind turbine configuration in terms of the support structure stiffness was highlighted as requiring investigation.

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, writers of standards and regulations, and possibly owners and operators of offshore wind farms.

Innovative features:
Recommendations resulting from the studies highlighting the factors that are benign and important open the way to far more efficient modelling of the offshore wind turbine.
