1 Demand inspired research in offshore wind energy systems Jos Beurskens / ECN at-sea.org /

2 This presentation programme and experiences Update R&D top priorities based on recent developments

3 Initiated by ECN and TUDelft and designed in cooperation with relevant partners from all relevant sectors ( ) Bridging gap between WE sector s s optimism and the offshore sector s s skepticism Awareness needed for policy measures Create opportunities for the industry R&D topics inspired by demand
