Project title: FLOTANT Dynamic Cable Design
Project location: Europe
Client: Consortium of 17 partners from eight countries, including INNOSEA (part of OWC)
FLOTANT – an EUHorizon 2020-funded project – successfully completed the validation of an innovative dynamic cable concept for deepwater floating wind projects, unlocking the potential for greater wind power resources at lower cost.
The project consortium aimed to develop conceptual and basic engineering for a hybrid concrete-plastic floating windfarm, looking at innovative solutions for anchoring and mooring systems, and dynamic cabling, including performance testing. Its objective is to improve cost-efficiency and increase robustness and flexibility in floating wind subsea design for deeper waters from 100 to 600 meters.
Consortium partners INNOSEA (part of OWC), Hellenic Cables, ITA and University of Exeter have successfully completed the dynamic cable scope of work.
Our scope of work
- Hydrodynamic assessment and dynamic cable configuration determination and optimisation to develop a lightweight and high-performance dynamic cable
- Stability analysis and wave-structure interaction analysis to develop a new solution for offshore floating substructure
- Coupled simulations and global performance assessment of the integrated FLOTANT solution
- Solutions to improve cost-efficiency, robustness and flexibility in subsea design for deeper waters – 100-600 meters
Start date: April 2019
Mooring, anchoring and dynamic cables elements of an offshore wind farm become more expensive as water depths increase.
- An expected 60% reduction in CAPEX and 55% in the OPEX by 2030 will be motivated by FLOTANT’s novel developments, including additional sectorial reductions due to external technology improvements.
- Overall, the FLOTANT solution will allow an optimisation of LCoE, reaching values in the 85-95 €/MWh range by 2030.
