Floating wind turbines give access to abundant wind resources over deep water – at least four times as much ocean space compared with bottom-fixed wind.
This gives an increased flexibility in site selection including the possibility to take advantage of areas with higher wind speed and areas with less social and environmental impact. The next five years will see significant technology development in floating wind to reduce cost, scale, and increase applicability.
In this chapter, DNV's Technology Progress Report covers:
- The potential of floating offshore wind
- Current status and cost
- New and improved design
- Expanding application
- Challenges that need to be overcome
Floating wind has great potential. Enabling this potential requires the industry to tackle a range of challenges with increasing application, scaling and cost reduction – all of which will be accelerated through collaboration and agreeing common rules and standards.
With the combined experience and eagerness from the oil and gas, maritime and bottom-fixed wind sector, DNV believes that technical and cost reduction challenges can be overcome. However, as with most industries, the real results come from deployment and here policy makers have a role to play. Long term targets, clear regulations that are not too country-specific, and incentives will give the supply chain the visibility to attract the necessary investment, allow for globalization and industrialization of the technology, and push floating wind cost down quickly to a cost competitive level.
