We need: 1. dedicated, economically feasible, large scale offshore wind energy plants (up-scaling, support structure, transport, installation and O&M concept, wind farm design, grid interface), which are compatible with the environment and nature and 2. are integrated in the electricity supply system.

• Capex increases instead of decreasing: (risk perception, stressed market, steel & copper prices). >>> More emphasis on cost reduction via technology improvement (integral design, new concepts). Originally this was considered as the exclusive domain of the WT manufacturers.
• Mismatch between state-of-the-art know how and actual legal requirements, in particular EIA’s. >>> Translate R&D findings in recommendations for better procedures in particular IEA requirements. Originally Institutional aspects were excluded from the programme. ExternalExternal environmentenvironment changeschanges (2)!(2)!
• General applicable research results from other countries available. >>> Co-ordinate and avoid unnecessary duplications, particularly in the field of nature impacts.
• Knowledge about entire spectrum of offshore wind energy is widely dispersed. >>> Independent expertise centres (like We@Sea, D, DK, E, GB) essential to secure access to state-of-the-art knowledge and maximise learning. Present programme does not require extension of the initial proposal. ExternalExternal environmentenvironment changeschanges (3)!(3)!
• Governmental incentives and payment mechanisms have a huge influence on market development, both in negative and positive sense. >>> Benchmark and critically analyse the efficiency of various incentives implemented in different countries. Avoid contradictions and unwanted by-effects. Original programme excluded policy research. • General recommendation. >>> Allow time (> 1 year) for R&D consortia to mature and allow for easy changes of content and participations (compare IP’s of FP6 and FP7) ThankThank you!you!
