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 …

Agenda
The WindFloat Project 5
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 Project6
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 7
Total displacement of the WindFloat is 2.750 ton. Total weight of the hull is 1.200 ton

The WindFloat project is structured to follow a phased / risk mitigation approach
The WindFloat Project
The WindFloat Project 11
The Project is promoted by…
…in a joint venture…
…and counts with the support of…
The WindFloat project was structured as a Joint Venture, WindPlus
The WindFloat Project
WindPlus
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
12
The development of the WindFloat project carried enormous challenges due to the lack of know-how in Portugal

The WindFloat Project 14
Effective Risk Management must be embed into the project since the very early beginning
The WindFloat Project
Risk Management methodologies implemented through out the project were key for the success of the project
• HAZID – Hazard Identification Study
• Conducted at an early stage of the project
• Focus in the Project Execution stage
• Provided inputs to the FEED stage
• HAZOP – Hazard and Operability Study
• Several workshops conducted during FEED
• Participants were the teams involved in the activities and engineering team
• Provides input to the FEED stage
• HIRA – Hazard Identification and Risk Assessment
• Workshop conducted prior to execution of the activities
• Plan and procedures of each activities already defined
• Outcome provides inputs to reduce the risk while executing the activities
