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 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

5
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 Technology
Total displacement of the WindFloat is 2.750 ton. Total weight of the hull is 1.200 ton

The WindFloat Project
The WindFloat project is structured to follow a phased / risk mitigation approach

Phase 1 – Demonstration
Capacity: 2MW WindFloat prototype
Location: Aguçadoura, grid connected
~6 km of coast, 40 - 50 m water depth
Turbine: 2MW offshore wind turbine
Test period: 24+ months

Phase 2 - Pre-commercial
Capacity: ~27MW (~5 WindFloat units)
Location: Portuguese Pilot Zone
Turbine: Likely Vestas and other, Multi MW

Phase 3 - Commercial
Capacity: 150MW, gradual build-out
Location: TBD
Turbine: TBD

The WindFloat Project
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

11
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

Risk Mitigation Activities

The WindFloat Project

13
The WindFloat Project
Effective Risk Management must be embed into the project since the very early beginning

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

  • 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

  • 5. 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 5
  • 6. 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 6
