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.

Processes



Key challenges in wind operation

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

Maintenance is one of the largest controllable operating costs in capital intensive industries Maintenance influence: Commercial risk; Production; Safety; Cost

• 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

Hywind Demo - concept verified



Hywind Performance

• 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

• 2nd year was 9,1 m/s, 3%

below normal

• 1st year was 12% below

normal

• Overall availability 94,5 %

• Capacity factor at 47,3%

• 4390 full load hours for 2011

(average in Norway ~2100)

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.

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



Rescue from hub

– use of milan and 2 metre rope



Rescue from nacelle – outside tower



Rescue outside



Other HSE activities at Hywind in June



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

From Idea to Commercial Concept

Large Parks, 500-1000MW <10 years

Pilot Park, 3-6 turbines <5 years

Concept 2001

Model test 2005

Full-scale prototype 2009

• The technical concept is considered proven

• Next step: Pilot parks to demonstrate improvements and cost reductions

• Large parks 500-1000MW is the end game objective

Cost competitive with bottom fixed in 2020’s



Hywind Pilot Park objective to demonstrate

cost efficient and low risk solutions for

commercial scale parks

• 12 – 15 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

Alternative locations for Pilot Park in

or Maine, US or Scotland



• Scaled-up conceptual design (5+ MW) reduced cost/MW

• Standardisation and mass production reduced unit cost

• Optimised fabrication lines higher productivity

• Assembly, transportation and installation higher productivity

• Combined mooring systems, sub station reduced unit costs

• Better and more stable winds higher income

• Easier decommissioning reduced cost

Floating wind will be cost efficient in a mature market
