• Total capacity: 25MW capacity, (3 units equipped with MHI-Vestas V164)
• Total investment: ~125M€ (partly funded by the EC)
• Strong Institutional Support:
• EU: NER 300
• Portugal: Feed-in Tariff, APA
• Location: 20 km off the coast of Viana do Castelo, in water depth of 85-100m, in an area of sand and sediments, suitable for mooring
• Interconnection: to be constructed by REN, allowing a direct connection at 60kV with no onshore of offshore substation
• Construction: several shipyards options available close to final location. Turbine installation quayside
• Floating structure certification: designed for 25 years, certified throughout design, construction and installation by ABS, an independent party
• Key Dates:
• FID: Q2-2017
• Start Fabrication: Q3 2017

Heave Plates (Dynamic Stability)
• Any conventional commercial Turbines
• Minimum redesign in:- Control system –
software- Tower – structural
interface
• Displaces some water between columns to compensate for changes in mean wind velocity and direction
• Located at the bottom of each column and used to achieve operating draft
• More water in the columns not supporting the turbine
• Move platform natural response above the wave excitation (mass of entrained water)
• Viscous damping reduces wave induced motions

• Produced more than 17 GWh
• Availability in Oct.2014-Sept. 2015 was 96%
• PPI’s dynamic models were validated
• Power curve within manufacturer’s tolerance
• Survivability demonstrated vs. 20-year storm
Behavior of WindFloat in line with the models and turbine is following its original power curve.
Windfloat has suffered waves above 19m.

Large correctives
Decommis-sioning
• Fully conducted onshore• All structures are alike• Certification: strict guidelines from oil & gas industry
Description Implications
• Lower design risk• Lower execution risk
• Anchoring technology with >60 year experience• Big flexibility on soil conditions • Lower need of geotechnical studies
• Lower geotechnical costs and risk
• Shorter weather windows required• Fewer and simpler operations• No use of special installation vessels
• Lower execution costs and risk• Lower weather risk
• Shorter weather windows required• Fewer and simpler operations to be conducted offshore• No use of special O&M vessels
• Lower execution costs and risks• Lower weather risk
• Simple operation• No impact whatsoever on the site• All works done onshore
• Lower execution risk• Lower third party risk

WFA: Large correctives will be conducted quayside in a protected environment
Mooring and interarray cables are designed for a simple release and hook-up

Quays already identified with sufficient draft for O&M work quayside
Large componentreplacements are conductedquayside in the port usingstandard onshore cranes.Port of Vigo has confirmedits availability for theseactivities.Windplus already has quotesfor suitable onshore cranes
