Floating Wind Joint Industry Programme: Phase V summary report

The Floating Wind Phase V Summary Report covers the research undertaken by the Floating Wind JIP to address some of the technical challenges of moving from fixed-bottom to floating offshore turbines.

Front cover of report

Overview

2023 saw the floating wind industry continue to make significant milestones towards full scale commercialisation, with the commissioning of several floating wind farms and new lease areas being announced.  

However, current pilot and pre-commercial projects alone show the number of key stakeholders required to successfully deploy floating offshore wind farms, signalling the importance of collaboration to scale this industry and overcome its inherent technical challenges. 

Key findings:

The report provides an in-depth summary of the following projects:

  • Fabrication, Infrastructure and Logistics (FIL): researched common infrastructure requirements and constraints for large scale floating wind farms to understand investment needs, and to provide a framework for port selection for developers and fabricators.
  • Major Component Exchange with Self-Hoisting Cranes (SHC): identified potential solutions to conduct onsite major component exchange of Wind Turbine Generator (WTG) nacelle components without relying on large heavy lift vessels or towing a substructure to port.
  • Stick Building Wind Turbine Generators On-Site (SBOS): assessed installation methods for WTG assembly at floating offshore wind sites.
  • Fatigue Analysis of High Voltage Electrical Equipment in Floating Structures (HVEF): investigated high voltage electrical equipment design and its suitability for operation in offshore floating structures.  
  • Moorings System Redundancy, Reliability & Integrity (MRR&I): provided clarity around the definition of ‘redundancy’ in relation to a three-cluster mooring system – with either a single leg or two legs per cluster.
  • Dynamic Cable Failure Rates and Standards (DCFR): provided insight into the feasibility for the application of dynamic cables in floating wind and advise on the potential changes required in dynamic cable design, qualification and testing.
