Abstract
For onshore wind energy, a detailed wind measurement campaign is required by financiers in order to perform accurate site energy yield assessments. When considering the offshore environment, there is an additional requirement to understand the accessibility of the site, which is determined by the wave climate.Accessibility has a direct impact on the wind farm availability, and a resulting influence on the power production and the financial viability of a project. However, performing climate measurement campaigns in the harsh offshore environment are expensive and also the resulting data sets are frequently of poor quality. Therefore, there is a need to better understand the relationship between wind and wave climates and the resulting cost of energy from offshore wind. In addition, it will be possible to reduce the uncertainty associated with offshore wind by quantifying how the length and the quality of data obtained from a measurement campaign influences the predicted lifetime availability and the energy production values.
