1 Norway s solution: Hywind- world s first full scale floating turbine Dr. Nenad Keseric Asset Manager/Specialist Statoil ASA MPR RE Operations Strategy and Support

2 Leveraging Statoil s offshore oil and gas competencies, focussing on: Offshore wind Carbon capture and storage

3 Building the Portfolio: Material positions in bottom fixed offshore wind Project execution to operations: Sheringham Shoal, UK 317 MW In operation, 2012 Working to bring technology costs down: Dudgeon Offshore, UK Up to 560 MW Under development Larger projects, deeper waters, further from shore: Doggerbank, UK Up to 9 GW Under consent

4 Statoil Renewable Goal: Maximise value in offshore wind 2.3MW 10 GWh Hywind Demo 317MW 1.1 TWh / yr* Sheringham Shoal 402 MW 1.1 TWh / yr Dudgeon 60 MW 140 GWh / yr* Hywind Pilot Park Up to 9000 MW Dogger Bank I Increase I Portfolio *total average production for Scira Security Classificati on: Internal - Status:

5 5 Hywind floating wind concept: Game changer Taking offshore wind to the next level over 12 years from idea to commercial concept 2014 Onshore connected parks 2009 Onshore connected parks 2005 Pilot park Demo Market Focus Model test Cost Focus Concept & theory Technical Focus Idea

6 SCALE MODEL TEST EXPERIMENTS 2005 Demonstration of system behaviour Validation of numerical tools Model scale 1:47 Irregular waves, turbulent wind, and various control strategies Classification: Open 6

7 Hywind Demo Assembly and Installation

8 100 m total height 65 m tower Work platform 17 m above mean water level 82 m rotor diameter 24 m clearance between rotor tip and mean water level 800 m to anchor 50 m mooring bridle for yaw stiffness J-tube for pulling in electrical cable at 44 m depth Mooring line connetion points at 54 m depth 100 m draft 30 t clump weight Classificati on: Internal

9 Integrated Operations implementing O&G experience 9 Integration of people process and technology Use of data, collaborative technology and multidisciplinary work Databases and data management

10 Hywind Operation and monitoring 10

11 Full scale measurements 11 A total of more than 200 sensors: Waves wind and current (magnitude and direction) Motion and position of floater Mooring line tension Strain gauges at tower and hull (4 levels bending moments and axial force) Rotor speed, blade pitch and generator power Flap- and edgeways rotor bending moments Motion (tower pitch) / blade pitch controllers

12 Wind, heave and pitch behaviour Classificati on: Internal

13 Production in heavy seas Avg. wind speed: 16 m/s Max wind speed: 28 m/s Avg. significant wave height: 4,7 m Max significant wave height: 7,1 m Power production: 96,7% of rated power 24 hour trend periode during «Dagmar» storm Classificati on: Internal

14 Production in heavy seas 30 hours trend periode during a hevy storms Dagmar and Berit in December 2011 Max wind speed: 34 m/s Max wave height: over 15 m

15 A base for testing vessels and access systems 15 Test of: Fob Trim, Stril Merkur (MSDC12), Buddy, Fob Swath1, Bayard 3 Undertun prototype access system, MaXccess access system

16 Hywind Demo - concept verified In operation from September 2009 Excellent HSE record- no serious incidents Production: 37 GWh since start-up; 10,1 GWh in 2011 Capacity factor 50% in 2011 (industry standard 35%-45%) NORWEA prize for the best producing wind turbine in Norway in 2011, 3rd best in 2012 Production as good as or better than other 2.3 MW Siemens wind power turbines Experienced wind speed over 40 m/s and maximum wave height of 19 m. Floater motions have positive impact on operations All technical systems are working well concept verified

17 Floating wind - Potential markets North sea Norway and UK US, Atlantic and Pacific coast and Great Lakes Japan, Taiwan, Korea Iberian Peninsula and Mediterranean Sea

18 Hywind evolution Use of experience - Improved design Bigger turbine Smaller hull Lower costs Site specific Test multiple units in park-configuration Optimise assembly and installation Verify scaled up, lighter design Verify reliability and availability of optimised multiturbine concept Reduce construction risk for future full scale park Possibility for multi use.

20 Hywind Scotland Pilot Park 5 x 6 MW turbines Location: Buchan Deep outside Peterhead Agreement for lease with The Crown Estate in 2013 Consent in 2015 First deliveries to grid 2016/17 Peterhead Hywind Scotland Pilot Park Aberdeen Primary objective: Demonstrate cost efficient solution and lower risk for commercial scale parks United Kingdom Edinburgh Classification: Open 20

21 Why Hywind? Floating has benefits and potential to step-change offshore wind technology Bottom-fixed Floating - Adaption needed for each unit Fabrication - Offshore assembly Installation + Standardized, mass production + Inshore/onshore assembly - Piling noise during installation - Often in sight from land - Seabed footprint - Limited shallow water resources Environment Resources + No piling needed + Can be placed out of sight - Mooring line spread + Almost unlimited deepwater resources + Often better wind conditions + Can be placed close to consumers + Proven Technology - Only proven in singular setting, further demonstration ongoing Lower, but less reduction potential Cost Higher, but larger reduction potential Classification: Open 21
