Conclusions
WHO WE ARE
Ocean Winds ( OW ) is the result of a Joint Venture between two of the biggest players in Energy:
o Engie, French multinational energy and services company andglobal leader of zero-carbon transition and
o EDPR, global leader in the renewable energy sector and theworld's fourth-largest wind energy producer
born to lead the Offshore Wind Energy Business.“ In an industry where size matters,
relevance is critical. Only elephants play this game. Together
we are one.”
An investment framework announced to market May 2019 with ambitious growth targets…
…paving the way for a greener future, by strengthening offshore growth, increasing efficiency and returns
OW selective investment criteria
Sound market fundamentals
Stable regulatory frameworks
Contracted NPV (i.e. cash-flows visibility)
Compliance with target risk return profile
Maximize projects self-funding

Mooring Line Failure Tow to Port Strategy
If a three mooring line system is required, the mooringline failure case needs to be accommodated by theplatform and cable connection systems.
To enable a tow-to-port strategy, a solution needs to beemployed to keep the cable system connected, allowing forquick connection / disconnection and reliability.

Agenda
Conclusions and take-aways
14
• 66kV cable technology and dynamic cable design has mature inthe last years and were demonstrated on the WindFloat AtlanticProject;
• Floating wind farms require a new interface between foundationand mooring designer, cable and hardware supplier and offshorecontractor. The allocation of each scope of work and the use of amulti-contract approach require skills and resources tomanage;
• The construction program brings the IAC cable installation andtermination towards the critical path. Optimizing the installationprocess and the cable termination is key to achieve first powerquickly. Furthermore, installation process needs to be inline withthe floater and turbine installation rates.
• The lessons learned and experience from the WindFloat Atlanticproject will be transferred for the future commercial projects ofOW around the world.
