Case study Beatrice Demonstrator & Kincardine Offshore Wind Farm,

The substructure choice
• The wind industry has a variety of substructure choices:
• Mono piles
• Concrete gravity
• Tripods
• Jackets
• Floating
• Hybrids
• At present the dominant form is the mono pile
• This will change as turbines get bigger and the industry moves into
deeper waters
• Jackets will come into their own
• Floating is in its infancy but it has a number of advantages
• Primarily water depth limitations
• Suitable for any water depth over 40 m
Substructure Choices
Practical Examples
Beatrice: why did we choose jackets ?
• Water depth too deep for monopiles
• Comparison of Jackets and tripod’s
• Results favoured jackets
• Talisman had more jacket experience
• Fabricators / designers revealed more confidence in jackets:
• Potential to improve design and reduce costs
• Scaling up jackets for serial production
• Lighter so less steel and more installation vessel flexibility
• Greater familiarity

Application of Jackets in Offshore wind
• The first application occurred at the Beatrice Demonstrator Project
• Two OWEC towers
• Fabricated by BIFAB and installed in 2006
• Operational for 8 years
• To date more than 100 jackets have been installed
• 2008: Alpha Ventos, Germany - 6 OWEC Towers, 2008, BIFAB
• 2011: Ormonde, UK - 31 OWEC Towers, BIFAB
• 2012: Thornton Bank, Belgium: 49 OWEC Towers, Smulders
• 2014: Nord Sea Ost Germany: 48 jackets, Aker Solutions
• Design
• Most turbine jackets to date are of the OWEC Tower design
• BIFAB and Atkins have announce a new design
• Some developers are developing in house designs, DONG
• Floating offshore wind technology is proven
• HyWind – Norway
• WindFloat – Portugal
• Next stage is
• Pre-commercial developments
• Pilot has unparalleled experience
• Unique opportunity in Scotland
• Government announced higher incentive for floating pilot programmes
• Pre commercial developments get ROC banding (3.5) for floating
Floating Pilot Opportunity at Kincardine
• Develop a pilot floating offshore wind farm in North-East Scotland with a capacity of 50 MW • Up to 8 machines of 6 to 8 MW
• Consent under “survey, deploy and monitor” policy from Marine
Scotland
• Access Scottish Government special support for floating: • 3.5 ROCs for pilot programmes • Operational by 30th September 2018
•Commercial in
confidence
Kincardine Project Objectives
Kincardine: current status
• Path to lease from TCE
• All environmental data gathering requirements complete
• Radar and navigation survey complete
• 50 MW grid connection with SSE at Redmoss
• Scoping report completed
• Scoping opinion from received
• Habitats Resource Assessment completed
• Statutory consultation meeting completed
• Discussions with the major stakeholders in initiated.

confidence
Kincardine concept Selection: Semi Submersible
• Maturity: Spar and semi more mature
• Duplication: Statoil spar pilot at Buchan deep
• Familiarity: the Kincardine team more familiar with semi-subs
• Scottish fabrication: can fabrication on east coast of Scotland
• Tow and installation: easy tow from Scottish yards
• Operability: East coast ports suited for repair and maintenance

UOE pipes are mainly supplied for linepipes. MTO for structural
pipes for jackets are not always suitable for UOE because of the
variety of the dimensions (smaller lot for each dimension).
