Carbon Trust has been working with government and industry to accelerate offshore wind for >10 years
Active in ¾ of the UK’s offshore wind projects
Offshore Wind Accelerator (OWA)
• Collaborative R&D programme involving 9 developers, Scottish Government, & Carbon Trust
• €100m programme (2/3 industry, 1/3 government)• 2008-2017: >100 RD&D projects completed• Leverage ratio = 13.5 : 1• Industry-led, market-pull approach• Programme running to at least 2020

Current momentum is at risk, with notable gap in deployment from 2020-2025
• Typical project development timeline = 6-8 years
• Need activity now to create pipeline of projects from 2025

2: Low cost offshore wind means more deployment globally, which will require floating technology
UK:• Offshore wind-heavy UK energy strategy
could require ~50 GW by 2050 (‘Sector Deal’)• 50 GW OSW in the UK will require floating
technology
Global:• Threshold much earlier in several markets
(e.g. Japan, Taiwan, USA)
Export opportunity for first movers
1: Floating can match much of the cost reduction seen in fixed offshore wind, if deployed at scale

Several challenges for large scale deployment of floating offshore wind
COST+
RISK
Dynamic cables & connectors
Integrated design
Mooring systems
Logistics (construction, O&M)
Substructure optimisation
Wake effects
Floating substation
Environmental & social impact
Turbine optimisation
Monitoring, inspection, maintenance, and repairs
R&D needed to: - Develop and de-risk
technology - Reduce costs
Floating Wind JIP has been set up to investigate commercial deployment challenges for floating wind

Infrastructure & Logistics
Three projects delivered in 2017:
Focus on commercial scale floating wind farms
Design basis:
500 MW wind farm
(50 x 10 MW units)
Floating Wind JIP has been set up to investigate commercial deployment challenges for floating wind
Up to five studies planned for 2018, including two currently out to tender:
1: Turbine requirements & foundation scaling
2: Heavy lift offshore operations
Turbine design requirements:- Component sensitivity- Modifications
Impact of larger turbines (10-15 MW) on foundation design:- Substructure & mooring scaling- Scope for optimised integrated
designs
Heavy lift offshore operations:
- Feasibility, challenges, technology development needs
- Floating-to-floating lifts
- Utilising next generation DP2/3 heavy lift vessels
Focus on commercial scale floating wind farms
Design basis:
500 MW wind farm
(50 x 10 MW units)
• Floating wind has potential for large scale deployment within the next decade, supporting the global expansion of offshore wind
• Action needed now to create a pipeline of projects from 2025
• R&D activities are crucial to de-risking the technology and bringing down costs
• Collaboration will be essential to accelerate commercialisation, across sectors
• Floating Wind JIP is striving to accelerate technology development and de-risking
