6 Statoils area of interest Fixed wind turbines Further develop prospects in areas with adequate incentive schemes Floating wind turbines Use demonstration parks in US, UK or Japan, to refine the concept and mature supply-chain. This will ensure local content and pave the way for full scale commercial wind farms. Commercialize the Hywind technology. 6 Copyright Statoil Classification: Internal Corporate presentation: Crossing energy frontiers / 6

13 Key challenges in wind operation Maintenance is one of the largest controllable operating costs in capital intensive industries Maintenance influence: Commercial risk; Production; Safety; Cost Organisation Contractual obligation must reflect organisational capabilities for both OEM s and Owner Both parties must recognize each others capabilities Technology Asset owner must take responsibility for technical integrity and increase internal knowhow of the systems Cooperation Force lean thinking, component reliability on the suppliers through new standards both in production and operation OEM s Work should be carried out in accordance with recognised standards with transparency at all levels Owner should have an active retrofit program 13 Copyright Statoil Classification: Internal Corporate presentation: Crossing energy frontiers / 13

15 Hywind Demo - concept verified In operation from September 2009 Actual movements confirmed simulation model Floater motions have no negative impact on turbine performance Capacity factor 50% in 2011 Access and inspection confirmed to be satisfactory Technically verified 15 Copyright Statoil Classification: Internal Corporate presentation: Crossing energy frontiers / 15

16 Hywind Performance 2500 Downtime [hr] Production [GWh] November - November 94.6 Availability% Cap.Fact% Other 1500 Wind out of spec Grid 9, Turbine 6, Reduction of downtime with 1870 hr by better planning and quicker response Only one unscheduled stop in second operational year 50% production increase Average wind speed 2 nd year was 9,1 m/s, 3% below normal 1 st year was 12% below normal Overall availability 94,5 % Capacity factor at 47,3% 4390 full load hours for 2011 (average in Norway ~2100) 16 Copyright Statoil Classification: Internal Corporate presentation: Crossing energy frontiers / 16

17 Downtime November 2010 November 2011 Vibration alarm was eliminated in Mars 2010, through effective root cause analysis Manuel stop is decided by owner and can be minimised by preventive maintenance The two other major losses left are related to increased pitching at extreme waive and wind conditions. Better cooling system will be installed to eliminate the loss. 17 Copyright Statoil Classification: Internal Corporate presentation: Crossing energy frontiers / 17

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 for the periode: 96,7% of rated power. 18 Copyright Statoil Classification: Internal Corporate presentation: Crossing energy frontiers / 18

19 FOCUS ON HEALTH AND SAFETY (HSE) Same HSE standard as on all Statoil installations Focus on: Work permit system Boat landing, access, egress and PPE Lifting equipment No serious accidents Mitigating actions: Hands-on follow-up of Statoil and Siemens equipment and procedure Safety Job Analyses Table top workshops - Defined situations of hazards and accidents (DSHA) Safety training of personnel on-board Hywind 19 - Classification: Internal Copyright Statoil Classification: Internal Corporate presentation: Crossing energy frontiers / 19

24 Observations and ideas - rescue from nacelle Training is necessary to prepare the team and boost confidence Practice on internal rescue as space is limited Develop training packages together with service provider Use Hywind for training purposes Enable training on rescue tools, i.e. use of Milan rescue kit and fall arresters Attach Milan rescue kit to injured when possible Possible rescue time can be less than 1 hour for outside rescue Time from nacelle to boat based on speed with Milan Hub rescue is about 1:30min Helicopter rescue will reduce transport time to hospital but not necessarily rescue time form nacelle 24 Copyright Statoil Classification: Internal Corporate presentation: Crossing energy frontiers / 24

26 From Idea to Commercial Concept The technical concept is considered proven Next step: Pilot parks to demonstrate improvements and cost reductions Large parks MW is the end game objective Cost competitive with bottom fixed in 2020 s Concept 2001 Model test 2005 Full-scale prototype 2009 Pilot Park, 3-6 turbines <5 years Large Parks, MW <10 years 26 Copyright Statoil Classification: Internal Corporate presentation: Crossing energy frontiers / 26

27 Alternative locations for Pilot Park in or Maine, US or Scotland MW Production start 2016 Multiple units in park-configuration Verify scaled up, lighter design Optimise assembly and installation Reduce construction risk for future full scale park Hywind Demo Hywind II Hywind Pilot Park objective to demonstrate cost efficient and low risk solutions for commercial scale parks 27 Copyright Statoil Classification: Internal Corporate presentation: Crossing energy frontiers / 27
