About Source Low Carbon LLP Offshore Renewables Advisory and Development Services Partnership.
Established in 2013 by 3 partners, each with over 10yrs experience in UK
offshore wind and marine energy
UK based, registered in Scotland
Experience as developers, regulators and government advisors
Project Development: floating wind opportunities, commercialisation Neart na Gaoithe: Project Development: floating wind opportunities, commercialisation
of technologies for near-term deployment
Neart na Gaoithe:
450MW
Walney phase 3:
750MW
Advisory Services:
Policy and Regulatory: site selection, strategic environmental
assessments. Eg designing and managing offshore wind & tidal
tender for Isle of Man Government
Development Services: Advising UK offshore wind, marine
renewables developers

Floating Wind TechnologiesSemi-Sub
Combines the main principles of TLP, Spar
Eg Principle Power:
Windfloat: full-scale demo 2011
Relatively shallow draft
Spar Buoy
Large cylindrical
buoy stabilises
turbine using ballast
Large draft
Eg Hywind: Full-scale
prototype deployed
since 2009
Demonstration array
planned in Scotland
Tension Leg Platform
Buoyant structure, semi submerged
Tensioned mooring lines anchored on seabed
Concrete Floater
Water Depth (m)
Ideol Floatgen
Concrete structure
shallow draft, compact size
Damping Pool to reduce motion

Business Case for Floating Wind
Development Construction Operations Decommissioning
Opens up new areas for offshore wind: Current technologies limited to 40-50m.
Cost Reduction: alternative solution for existing projects with marginal economics.
Local Economic benefits: jobs, supply chain
Many advantages are technology-specific, general benefits include:
Reduced impacts on some receptors, egnoise for marine mammals, fish
Reduced ground survey work
Assembled onshore, transferred to site
Cheaper, more widely available vessels (no jack-ups)
Reduced installation costs and time
Can be returned to shore for significant maintenance
Complete removal
-
Path to Commercialisation
R&D, Pilot stage
Single Prototypes
R&D on concepts, designs, modelling.
Testing downscaled model in controlled environment
New structures, need to go through different stages of development before coming
on to the market.
Importance of perception by investors: increasing reliability, reducing cost
Some key Issues: integration of wind turbine onto platform, dynamic cables
Testing full scale model to assess concept maturity
7 experimental substructures (4 in Europe, 2 in Now Single Prototypes
Demonstration Arrays
Commercialisation
Small number of full scale devices.
Validates overall principles, manufacturing, installation, O&M
UK Crown Estate Round to award demo sites
Generation by Q3 2018
Serial production, commercial deployment
Much innovation is still needed to ensure reliability,
commercial viability
Need for government support
7 experimental substructures (4 in Europe, 2 in
Japan, 1 USA)Now
Planning
Underway

Island nations a new power source? Advantages
Climate change
Direct access to grid coastal communities
Will become cheaper than imported fuels
Low impact infrastructure
In many cases can be deployed from small ports
No need to reinvent the wheel: technologies, expertise, skills developed
elsewhere can be imported. Eg:elsewhere can be imported. Eg:
Environmental assessment, permitting procedures
Exchange of data and information
Requirements for ports, supply chain
Standards and standardisation
Time to plan:
policy, legislative framework, spatial planning
Caribbean-specific issues: eg hurricane risk

Leading Markets for Floating Wind Post Fukushima impetus
>80% offshore wind resource is in deep
waters
Government funding for demonstrators
Fukushima Forward: prototype
demonstration programme
Using wind turbines designed for
areas where wind speed exceeds class
1 design values
>90% worlds capacity of offshore wind
2013: 5GW installed, 60,000 jobs
Supportive policy, legislative environment, underpinned by renewable 1 design values
Good resource, intensive power demand
near coast
Leasing, permitting processes in place
Department of Energy funding initiative:
3 of 6 projects competing for funds (up
to $47m) are floating.
Embryonic offshore wind industry
Only offshore turbine in US waters
is on a floating foundation
environment, underpinned by renewable energy targets.
Driven by need to reduce cost, to build further from shore, deeper waters.
Floating technologies would unlock Atlantic, Mediterranean and deep North Sea areas.
Particular opportunities for Portugal, Spain, France.
Funding programmes: EU and member state level (France, UK).
-
Market Focus: Scotland, UK Deeper waters, environmental and other constraints near to shore
Seeking first mover advantage in deeper water technologies
Scottish Government: financial, political, legislative support
Renewables Obligation (RO): higher level of support for demonstration arrays.
Generation by Q3 2018
Planning, permitting, environmental
Proposed Projects
Hywind II pilot project Agreement for Lease awarded
Worlds largest offshore wind programme:
4GW generating, 1.5GW in construction, 40GW in development
Potential for commercial deployment of floating technologies on many of
these projects
Project pipeline supports the progress to commercialisation
Hywind II pilot project Agreement for Lease awarded
Crown Estate leasing programme: UK wide, RO incentive to locate in Scotland
Good opportunities for learning, strong appetite to share those lessons
-
Summary Floating Offshore Wind has significant potential reduce costs, open up deeper areas
Local economic benefits
Strong mid-long term potential for Island communities: post 2020
Many different technologies, several prototypes already deployed
Progress in key markets may accelerate commercialisation
Need for clear, stable policy: opportunity to put the right framework in place
