3 Why Floating Offshore Wind? Why Offshore Wind? Higher wind resource and less turbulence Large ocean areas available Best onshore wind locations are becoming scarce Offshore wind, including deep offshore, has the capacity to deliver large amount of energy Why Floating Offshore Wind? Limited locations with shallow waters (mostly in the North Sea) Most of the offshore wind resource is in deep waters Unlimited installation sites available Less restrictions for offshore deployments and reduced visual impacts Enormous potential around the world: PT, Spain, UK, France, Norway, Italy, the Americas, Asia The WindFloat Project 3

4 Deep Offshore Wind: Floating or Fixed? Deep offshore wind potential goes in line with the quality of the resource and the availability of areas to explore EU15 Potential Good offshore wind resource (load factor > 3.000h) Offshore wind potential is mostly in transitional and deep waters (1) (~65 %) Energy Potential >700 TWh (~220 GW) Ports and docks available along European coast (1) Analysis limited to 100m water depths Mean Wind speed (50m) Depth (m) Offshore potential EU15 77 GW >140 GW Source: Greenpeace & Garrad Hassan 2004; IEA; Global insight; Portuguese & Spanish Potential Continental shelf ends near the coast Grid connection available near the coast Limited Potential for water depths < 40m 250 km of PT Costal Line suitable to be explored Energy Potential in PT >40 TWh (~12 GW) Energy Potential in SP >290 TWh (~98 GW) Depth (m) km European Bathymetry Offshore potential PT 2 GW >10 GW SP 18 GW >80 GW Source: Univ.de Zaragoza Evaluación Potencial Energías Renovables (2007) EDP INOV Technology Development 4

5 Deep Offshore Wind: Floating or Fixed? Offshore wind technology is likely to follow Oil &Gas addressing the deep offshore wind challenges Monopiles Basic extension of turbine tower w/ transition piece Jackets Economically feasible in shallow water depths (10-30m) Economically feasible in transitional water depths (30-50m) Several jackets successfully installed at depths of less than 50m (Beatrice in 2006 was the first project to deploy at 45m) Other fixed (tripods, tripiles, gravity bases, ) Floating Very limited experience Similar depth limitations as jackets Expected economical feasibility in deep waters (50-?m) Still limited experience EDP INOV Technology Development

8 The WindFloat Technology The main characteristics of the WindFloat leads to High Stability even in rough seas Turbine Agnostic Conventional turbine (3-blade, upwind) Changes required in control system of the turbine High Stability Performance Static Stability - Water Ballast Dynamic Stability - Heave Plates and active ballast system - Move platform natural response above the wave excitation (entrained water) - Viscous damping reduces platform motions Efficiency Closed-loop Active Ballast System Depth Flexibility (>40m) Assembly & Installation Port assembly Reduced risk and cost No specialized vessels required, conventional tugs Industry standard mooring equipment The WindFloat Project 8

9 The WindFloat Technology Due to the features of the WindFloat, the risk and cost of offshore works is significantly reduced The WindFloat requires NO PILLING is structurally decoupled from seadbed is independent from depth is assembled and commissioned quayside does NOT require high lift capacity vessels Reduced Risk and Cost The WindFloat Project 9

12 The WF1 Project (Prototype) The WindFloat project was structured as a Joint Venture, WindPlus The Project is promoted by in a joint venture WindPlus and counts with the support of The WindFloat Project 12

13 The WindFloat Project The development of the WindFloat project carried enormous challenges due to the lack of know-how in Portugal The project followed a risk mitigation approach but the challenges were enormous project being done for the first time Lack of offshore know-how in Portugal different cultures involved(us, Denmark, Portugal, France) Collaboration between two different industries that have never worked together (Oil & Gas and Wind Industry) Standards & Rules for design exist but need to adapted The WindFloat Project 13

14 The WindFloat Project The project was implemented under a tight scheduled Project was completed in less than 2,5 years Fabrication completed in less than 9 months Task Project Start Pre-FEED Sep, 09 Jan, 10 Timeline PDR FEED Sep, 10 Turbine Selection Final Investment Decision Project Execution Detail Design Fabrication Offshore Installation Offshore Commissioning Testing and Monitoring Sep, 11 May, 11 Sep, 11 Sep, 11 Nov, 11 Dez, 11 Ago, 13 Significant space to improve project implementation schedule!
