conference & convention enabling the next generation of networks & services Challenges of New Significant Seabed User & Market Technologies Rod Seville HA i Limited
conference & convention enabling the next generation of networks & services A New Century – A New Offshore Technology Industry Arrives European governments agree that 20% of national energy generation should be produced from all renewable energy sources ! The result: New technologies generating energy from Wind, Tidal/Current & Wave motion are evolving / being deployed in the offshore marine environment to meet this commitment.
conference & convention enabling the next generation of networks & services Development areas will be located: Near shore & along coast lines Between islands & islands / mainland Further Offshore Probable impacts to telecommunications systems could/will be in the following areas: Cable Routings System Costs Cable Landing Approaches Cable Crossings Cable Maintenance Activities Decommissioning

conference & convention enabling the next generation of networks & services And Europe? Comparable Investment c £100 billion • • Installation of up to 5500 wind turbines (ex.UK) • Creation of 20+ Gigawatts of power by 2020 from offshore wind alone • c.19,000 km of Sea area allocated for development up to 2020

conference & convention enabling the next generation of networks & services Alternative Technologies • Wave, Tidal/Current are currently 2-5 years behind wind technology but are developing rapidly • Whilst Wind technology is moving further offshore, Wave, Current/Tidal technologies will likely remain relatively close to shore or on shallow continental shelves

conference & convention enabling the next generation of networks & services Areas of potential impact Telecom cable systems will/could be affected by Offshore Energy in several areas : • Cable Routing • Cable Landings • Cable Crossings • Cable Maintenance Methodologies / Procedures • System Decommissioning
conference & convention enabling the next generation of networks & services Considerations for the Industry Development & Innovation • Cable Corridors? - To suit the industry • Retain OOS routes?- Retain Shore End Landings as priorities • Collaboration? - Joint developments of cable routes? • Offshore Hubs? - Multiple system Hubs to Shore links (high fibre unrepeatered systems?) • Energy Tapping? - Longer System Lengths • Diversification? - Energy fibre to diversify/enhance systems? Drivers • Costs &/or issues of access/re-routing cables? • Benefits of collaboration on network diversification? • Decommissioning Costs?
