Improved FOWT

Improved methodology for High fidelity simulations and model tests of novel floaters for FOWT

Publieke samenvatting / Public summary

Aanleiding
In the latest market projections from the Carbon Trust, they forecast 70GW of floating wind capacity installed by 2040. Offshore floating wind (OFW) is emerging as a very promising renewable energy sector. Pilot and demonstration projects have shown the potential for similar, or even higher yields from floating turbines compared to bottom-fixed offshore wind turbines, as they can be situated in locations with stronger wind resources. Carbon Trust have identified several challenges in technology development that need to be addressed in order to enable commercially viable floating wind farms . Simulations and model tests have an important role in maturing the technology. MARIN is one of the leading testing centres for new floating wind concepts. As wind turbines grow in size it becomes more challenging to perform accurate and realistic model tests. Previously, demonstrator (pilot) projects were a popular way to gain experience in the technology. However, we have noticed that clients are moving away from such projects, due to the high cost and the relatively low impact on the technology.

Doelstelling
The floating wind market is becoming similar to the oil and gas market segment, in that it now requires an extensive set of numerical simulations to be validated using high quality model tests before construction and deployment offshore can begin. This requires both simulations and model tests to be as representative as possible of the full scale system. We propose an improved methodology for simulating and model testing floaters for floating wind turbines. The proposed approach will be robust and flexible and will allow for different concepts to be tested.
