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 …

Deep offshore wind potential goes in line with the quality of the resource and the availability of areas to explore
Deep Offshore Wind: Floating or Fixed?
0 10 5 km
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
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)

EDP INOV – Technology Development
Offshore wind technology is likely to follow Oil &Gas addressing the deep offshore wind challenges
Deep Offshore Wind: Floating or Fixed?
Monopiles
• Basic extension of turbine tower w/ transition piece
• Economically feasible in shallow water depths (10-30m)
Jackets
• 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 ,…)
• Very limited experience
• Similar depth limitations as jackets
Floating
• Expected economical feasibility in deep waters (50-?m)
• Still limited experience

The WindFloat Project 8
The main characteristics of the WindFloat leads to High Stability even in rough seas
The WindFloat Technology
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 9
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
Due to the features of the WindFloat, the risk and cost of offshore works is significantly reduced
The WindFloat Technology
Reduced Risk and Cost

The WindFloat Project
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
13
The development of the WindFloat project carried enormous challenges due to the lack of know-how in Portugal
