The GASPOC project and the global offshore atlases of siting parameters

<p>The Global Atlas of Siting Parameters for Offshore and Coasts (GASPOC) project aims at shortening the project development period for offshore wind farms, with faster energy integration, lower capital expenditure and lower operating expense. This value is brought by the partners DHI, DTU Wind, Vento Maritime and DECK1 through automatic data driven downscaling techniques, that are applied to meteorological, ocean and wave modeling and analytics, including the application to real test scenarios. GASPOC provides metocean data, including siting parameters for offshore wind turbines such as extreme winds and turbulence intensity, as well as extreme waves and joint wind-wave statistics. An ensemble of reanalysis data together with the spectral correction method (Lars&#233;n et al. 2012) is used to obtain the effective 10-min extreme winds at 50 m, 100 m, 150 m and 200 m, while the calculation of the turbulence intensity at heights above the surface layer also takes the mesoscale turbulence into consideration. We show the data of the siting parameters from GASPOC which support seamless application to strategic planning of offshore wind energy development.</p> <p>Reference</p> <p>Lars&#233;n X., Ott S., Badger J., Hahmann A.
