The state-of-the-art in offshore wind farming in Europe was examined, including the recent developments in offshore wind energy from the technical, financial and operation/ maintenance point of view and a review on the state-of-the-art in Offshore Wind Farm (OWF) development in the Mediterranean and Black Seas. The assessment and modeling of wind fields was another subject of the workshop: the analysis and assessment of the current wind climate in the Mediterranean Sea based on various sources of wind data, along with a user interface for the analysis of the Era-Interim wind data base were presented. The extrapolation to future climate conditions along with the involved uncertainties and the potential impacts to the economic part of OWFs were also examined. Site selection procedures were an additional subject of technical interest. In this context, a methodology for site selection procedures for OWF development in large ocean areas was proposed, along with a review on marine geological, geotechnical and geo-archaeological surveys for OWF planning. Numerical modeling issues of scour around offshore wind turbine foundations were also presented. Regarding environmental issues and their relation with the development and operation of OWFs, three reviews were presented with reference to: a) the criteria for assessing coherence of European networks of Marine Protected Areas (MPAs), using as a case study the coupling of MPAs with OWFs b) the state-of-the-art on overlapping human-driven threats distributions and c) the potential effects of an OWF development on the Mediterranean seal and the impacts on birds and marine biodiversity from such structures. In addition, the design of the experiment at the Mediterranean Pilot site and the relevant settling of communities on artificial substrates were discussed.
A special session was dedicated on some new and innovative floating structures related with atmospheric and sea environmental monitoring. More specifically, the design of a new structure providing in various ways wind and environmental monitoring within an OWF, and a technical analysis of two new moored multipurpose floating structures were presented. Finally, a review on undergoing European projects as regards multi-use offshore platforms and the direct relation with socio-economic issues was set out.
