Observations 觀察 Cost trends in offshore are already dramatic; comparison with onshore shows we ain t finished yet! Taiwan set to get into the Top 10 by 2024 Europe did not get it right first time witness LCOE trend; Taiwan has an opportunity to learn from somebody else s mistakes In construction phase the dominant failures have occurred with cables and foundations; a golden opportunity exists to avoid them through relentless focus on design and construction In O&M, gearbox damage dominate; leapfrogging to larger direct drive turbines could help? Taiwan specific issues typhoon & earthquakes - need focus and have no precedence in the European experience

Panel Questions 專家提問 1. What key lessons have we learned from designing offshore wind farms form your perspective. Are these lessons easily transferable? 2. Offshore wind in Europe went through a painful learning process with LCOE rising initially even until 2013 but seems to have turned the corner. Does Taiwan have to go through the same pain? 3. What lessons have we learned in Europe with respect to construction/installation that we can rapidly transmit? What can we not because of local conditions? 4. We always talk about Typhoons and Earthquakes what other issues in construction and O&M make it a challenge and an opportunity in Taiwan. 5. Has Taiwan Offshore Wind industry established guidelines for how to deal with typhoons/earthquakes in construction phase even if we have dealt with inplace performance under these conditions? Do we need these? 6. I think scale, competition and finance were keys to unlocking offshore wind costs; In scale, we have technology. Other panels have talked about what we can learn about competitive landscape and finance. What general and Taiwan specific technologies can help us push further, faster 7. Cables have been painful part of OWF 60%-80% of claims; what recommendations will you make to help Taiwan avoid the same statistics 8. Foundations the lessons we learned with grouted connections are they well learned in the specifics as well as the general that is check for errors in code and don t extrapolate O&G without thinking? 9. Where do you see the arms race of larger and larger turbines ending up and at what timescale? Gearbox vs DD? 10. What O&M challenges will we face when we have to do major component replacement and having to lift 1000t up 150m? 11. Floating? 12. Final message to our guests today?
