Offshore Wind R&D Conference 2015
October 13 - 15, 2015, Bremerhaven, Germany
Looking back the Offshore Wind R&D Conference 2015 was a great success. Two hundred participants from eleven countries met in Bremerhaven to present and discuss their latest findings and results in offshore wind energy research. The lectures and posters were presented by members of the RAVE initiative as well as by international experts from academia and industry.
The opening session started with a lively panel debate about the role of R&D in reducing the costs and technical risks of offshore wind energy. Including 10 sessions with 50 lectures and about 20 posters the scientific part of the conference provided ample opportunity to get comprehensive information on the current status of science and technology of offshore wind energy and in particular to have technical discussions.
The participants took advantage of the possibility to continue these discussions during the evening event. The unique setting in the Klimahaus Bremerhaven 8 ° Ost offered a great opportunity to socialize and network with other participants from research institutes, companies or authorities. The tour through the exhibition "Journey" in the Klimahaus contributed to a pleasant atmosphere for discussions on experiences and new results in the field of offshore wind energy.
The two conference days demonstrated that offshore wind energy research covers many different topics and research areas and that a lot of important results have already been achieved. But the conference also indicated that further research is necessary to reduce costs and risks of offshore wind energy and to increase economical as well as ecological security.
