Valorous Floating Offshore Wind Project

Project title: Valorous Floating Offshore Wind Project

Project location: UK

Client: Blue Gem Wind, Joint Venture between TotalEnergies and Simply Blue Group

Project Summary: Following our work on Blue Gem Wind’s Erebus floating wind project, OWC was contracted to provide owner’s engineering services on the pre-FEED for Blue Gem Wind’s Valorous floating wind project in 2022. The objective of our work is for the project to submit a successful lease application to the Crown Estate (TCE) in 2023 and to support the project through pre-FEED.  

About the wind farm

Valorous will be located approximately 47 km southwest of the Pembrokeshire coastline at water depths of 70-84 metres and is estimated to feature up to 27 wind turbines. The wind farm will have a minimum estimated capacity of 300 MW. 

Our scope of work

OWC acts as owner’s engineer for the pre-lease engineering and consenting scope of work. The objective of our work is to lead Blue Gem Wind to submit a successful lease application and guide them through consenting. OWC’s work includes: 

  • Management of Consenting scope 
  • Site Characterisation 
    • Preliminary Ground Modeling 
    • Site Boundary Refinement 
    • Contract Offshore Geophysical Survey (Contract) 
    • Ground Data Management 
    • Metocean – Floating Lidar And Onshore Metrological Mast management 
  • Grid Connection Support 
    • OTNR Engagement and Grid Management 
  • Port and Transport & Installation Strategy 
  • Pre-Lease Engineering
    • Innovative technology review 
    • WTG developments 
    • Market Engagement for fixed offshore substations 
    • Market Engagement for Electrical Equipment: Electrical balance of plant RFIs 
    • HDD feasibility study 
    • Export Cable Landing 
    • Onshore design synergies 


Every market and project presents its own set of challenges and unique requirements. Although Blue Gem Wind has previous offshore wind experience with the Erebus test and demonstration project, Valorous is an early commercial project with a much larger capacity and scope. We helped our clients address the following challenges: 

  • New market, Celtic Sea, with specific consenting procedure 
  • Competitive landscape 
  • New technology 
  • Large scale project 

Value added

OWC offers a unique position of delivering a vast array of engineering capabilities across varying disciplines, as well as utilising our established relationships with environmental consultants, which together have provided a holistic perspective to BGW. 

OWC worked with Blue Gem Wind previously and successfully delivered the consent application for the 100MW Erebus project, demonstrating our capabilities and continued value to our Client, as well as a deep understanding of the Celtic Sea.  

“We are pleased to continue the relationship with OWC and partners. Project design and development is a core skill of the UK supply chain, and we are delighted to award this contract to a UK business.”​
