Inter-array cables for FLOW in the Celtic Sea – Future requirements during construction and O&M phases

This event has concluded.

Celtic Sea Power and Global Underwater Hub held a one-day workshop exploring the future inter-array cabling requirements during construction and operational phases of the Celtic Sea Floating Offshore Wind project.

Meeting the Crown Estate’s target of 4GW of floating offshore wind (FLOW) by 2035 will involve building and installing over 200 FLOW platforms, all of which will require new inter-array cabling.  Increasing the UK’s FLOW capacity to 4GW would deliver 10% of the country’s current energy needs.

Design of these FLOW systems and associated inter-array cabling is in the early stages of development.  It is already very clear that there is significant need for expertise in manufacturing, operations and maintenance of cabling to meet the demand.  The supply of which could come from south-west England and south Wales, representing a huge socio-economic opportunity for the region.

With a clearer understanding of the scale and specification of cabling requirements for FLOW in the Celtic Sea, a roadmap could be established to help enhance and scale-up capability to meet these needs from within the region.


The day featured speakers from Celtic Sea Power, Equinor, Flotation Energy, bp, JDR Cables, ORE Catapult, Renewable Risk, Siemens Energy, Viper Innovations and Xodus Group. For full details, view the event programme. 


Attendees to the workshop:

  • Discovered the likely demand and requirements
  • Learnt about the current regional supply capability
  • Discussed how regional capability might adapt and/or scale up

This workshop was held in partnership with the Cornwall FLOW Accelerator (CFA) project, a collaborative initiative led by Celtic Sea Power (CSP), University of Exeter, University of Plymouth and the Offshore Renewable Energy Catapult.  It aims to develop tools, knowledge and data which accelerate the Celtic Sea FLOW opportunity and lay significant groundwork with respect to developing a pipeline at both a FLOW project and supply chain level.  The project is part funded by the European Regional Development Fund.
