  1. Innovations in transport and installation methods Henrik Fomsgaard Lynderup September 2009

  2. Future trends in offshore wind energy Larger projects More projects installed per year

  3. Financing and equipment availability are key challenges Large projects are stretched over more seasons Financing becomes more difficult More competition for ports and vessels More projects each year

  4. The solution is simple! • By optimized installation methods • By pre-commissioning onshore • Requires specialized vessels • Requires flexible start dates Faster project execution Year-round operations Staggered projects

  5. Minimizing offshore work is a good idea! Cost index for installation, commissioning and testing 1,0 Siemens approach today 0,9 0,8 0,7 0,6 0,5 0,4 0,3 0,2 0,1 % man hours used onshore 100 10 20 30 40 50 60 70 80 90 Fully-assembled offshore Fully-assembled onshore

  6. It all links together… Fully assembled turbines in the port • Specialized quay and equipment • Specialized vessels with 350 Nm reach • High utilization to minimize price • An accessible market • Minimum 250 turbines per year in 5 years within reach

  7. A centralized setup will improve efficiency Serial assembly at the quay wall

  8. Specialized vessels are required to increase volumes and utilization Larger volume in port Sea Installer Larger range from port • Faster • More WTGs on board • Less weather-sensitive Source: A2SEA Specialized vessels Year-round installation High utilization of vessel and port Source: Beluga Hochtief Offshore
