A big global market for offshore wind
►Firm European commitment►2020: 40 GW; EUR 66bn►2030: 150 GW, EUR 145bn►Significant developments in
China, Japan, Korea and USA►Near-term large market is for
bottom-fixed wind farms►Increasing interest in
developing floating concepts
21
Main drivers► Battle climate change► Security of supply► Industry value creation
Copy from IEA Energy Technology Perspectives 2012
Stern Review (2006): ..strong, early action on climate change far outweigh the costs of not acting.
IEA 2DS scenario: 15 % wind in global fuel mix by 2050
22

One big advantage: relatively easy installation!
► In-shore assembly in sheltered waters
► Tug-boats for transport to site for installation
► Alternative: WindFlip?

► It is costly and sometimes impossible to have maintenance staff visiting offshore turbines
► Remote presence: Remote inspection through
a small robot on a track in the nacelleequipped with camera / heat sensitive, various probes, microphone etc.
Remote maintenance through robotized maintenance actions

Rounding up► Remarkable results are already achieved by industry and
R&D institutes on deep offshore wind technology► Technology still in an early phase – Big potential provided
technical development and bringing cost down► Research plays a significant role in providing new
knowledge as basis for industrial development and cost-effective offshore wind farms at deep sea
► Cooperation between research and industry is essential for ensuring relevance, quality and value creation
► Test and demonstration, also in large scale, is vital to bring research results into the market place
► Offshore wind is a multidisciplinary challenge – international collaboration is the answer!
