4 The status and potential of floating offshore wind The case for floating wind in the new offshore landscape 4

5 Offshore wind 2016/2017 The 402-megawatt Dudgeon project, under construction off the north Norfolk coast, is the first offshore wind farm to obtain financing under the U.K. government s new contract for difference system, This is a big warning shot across the bow for other renewables and really great news for German rate payers Three of the four winning bids are practically merchant-risk projects that will mostly rely on the wholesale power market." 5

6 Brief history of floating wind: 1970 s: early concept by Professor E. Heronemus 1990 s: first small scale tests 2000 s: kw range 2010 s: several MW prototypes tested Technical feasibility has been demonstrated now Current focus: increase TRL and reduce CoE

7 Key recent milestones for floating wind technology 2009: Hywind demo 1 st spar buoy 2011: WindFloat demo 1 st semi-sub decommissioned in : Kabashima/Goto Spar 1 st concrete/steel 2013: VolturnUS 1 st concrete semi-sub 2013: Fukushima Compact Semi 2MW 2013: Fukushima floating substation floating substation 2015: Fukushima V shaped semi sub 7MW 2016: Fukushima Advanced spar 5MW 7

8 Looking forward, the first arrays are coming soon WindFloat Atlantic 27.5 MW off Portugal s coast 30 m in funding from NER300 Operation aimed for 2018 Hywind Scotland 30 MW off Peterhead in Scotland 5 x 6MW turbines Financed by ROCs In operation from 2017 France: 4 projects awarded Gruissan/Mediterranean: Quadran, 4 x 6.12MW Senvion, IDEOL (damping pool), Bouygues. Construction in Port-La-Nouvelle Groix/Atlantic: Eolfi + CGN (China), 4 x 6 MW GE Haliade, DCNS, Vinci. Construction in Brest PGL: EDF EN, 3 x 8MW Siemens, SBM/IFPEN. Construction TBC EFGL: Engie/EDPR/CDC, 4 x 6MW GE Haliade, Eiffage/Principle Power, Construction TBC 8

9 Looking forward, the first small projects are coming soon Japan: NEDO funding Confirmed consortium: Hitachi Zosen, Ideol (platform designer) Two 3-5MW turbines, steel and concrete Ideol platforms Commissioning Kincardine Pilot wind farm 48 MW south east of Aberdeen Semi-subs platforms Taiwan Eolfi to develop at least 4 commercial floating wind farms up to 2GW / 300 turbines in total By 2025 Gicon SOF First ever large scale TLP prototype Siemens 2.3 MW Baltic Sea Commissioning planned for 2018 FLOATGEN Demonstration project in France Ideol platform 9

10 Looking forward, the first small projects are coming soon Hywind US Pursuing opportunities for Hawaii and Californian offshore wind project VolturnUS array 2 x 6 MW in 95 meters of water depth 3m USD from DoE to assist completion of a full scale design 40m USD in DOE funding to support completion of design and construction of the project Goal to install up to 5 GW of floating wind in Maine by

12 CAPEX Capex distribution (spar technology) Mooring Supply 5 % Installation of WTG & Substructure 10 % Electrical Infrastructure Supply 15 % Other 8 % Anchoring Supply 12 % WTG Supply 25 % Support Structure Supply 25 % DNV GL assessment. First-of-a-kind windfarm, FID 2015, 600MW park size, Spar technolgy Capex differences between concepts (illustration only) Capex is currently high (5-6M/MW) with current technology Foundation (support structure, mooring and anchoring) has a significant contribution to the overall capex Some differences between concepts; semi-sub technology has more costs related to the support structure but less cost related to installation TLP technology has less cost related to support structure but more costs related to mooring and anchoring and installation. 12

13 Cost reduction potential - Three scenarios used as a basis for the study Base case 2020 scenario 2030 scenario First-of-a-kind (FOAK) First-of-a-kind (FOAK) Nth-of-a-kind (NOAK) FID 2015 FID 2020 FID MW Same geographical location and size as the base case Based on current technology and market conditions No large scale floating wind installed, draws on cost reduction in the time from 2015 to 2020 Same geographical location and size as the FOAK case Cumulative installed floating wind capacity globally 20 GW (indicates expected learning effect) Base case is current market (Europe) and technology situation - E.g pilot park costs scaled to a large scale wind farm.

15 Floating wind power in Norway Opportunities and challenges In 2014 DNV GL supported a thesis on the potential for the Norwegian companies in the emerging floating wind industry In-depth industry interviews and questionnaire to 50 companies, showed considerable interest and involvement in the industry already in Diversification is emphasized as an industry need 15

16 WIN WIN - Wind-powered water injection Assessing a new concept for water injection, utilizing wind power Integration with O&G operations is already ongoing. WIN WIN is DNV GL s concept for a new generation of oil recovery technology, currently being assessed by DNV GL and JIP partners. It comprises a floating wind turbine which supplies power to a water injection process. The concept is a fully stand-alone system that includes pumps and basic water treatment. Our ambition is that WIN WIN will reduce costs, increase flexibility, and reduce emissions. WIN WIN phase 1 main conclusions 1. Commercially competitive alternative in a range of cases 2. No technical showstoppers identified 3. Technically feasible 16
