  • Geophysical survey work completed on ScotWind projects, Broadshore and Bellrock
  • Campaign extended to include ‘INTOG’ Innovation projects, Sinclair & Scaraben


Preparatory survey work on four new floating offshore wind farms has been completed in the North Sea.

Edinburgh-based BlueFloat Energy | Renantis Partnership commissioned marine infrastructure services and survey experts Acteon to map and analyse the composition and structure of the seabed at its floating offshore wind sites – the 900 MW Broadshore project, 50 km north of Fraserburgh and the 1,200 MW Bellrock project, 120 km east of Aberdeen.

The survey work at the sites also included the Partnership’s two 99 MW innovation projects, Sinclair and Scaraben which lie adjacent to Broadshore and were secured in the Crown Estate Scotland’s ‘INTOG’ innovation auction earlier this year.

The Ocean Fortune vessel, designed specifically for year-round operations in the North Sea, was mobilised from Peterhead. The surveys were carried out by Acteon’s offshore site investigation services team, with onshore support provided by Acteon’s operations centre in Westhill, Aberdeenshire and its data centre in Livingston, West Lothian.

David Robertson, BlueFloat Energy | Renantis Partnership Portfolio Director, said: “An extensive analysis of the seabed conditions is a key part of the journey to delivering commercial scale floating offshore wind and as well as surveying our two ScotWind projects, we have been able to adapt this scope of works to include our two innovation projects secured via the INTOG leasing round earlier this year.

“One of the main benefits of floating wind farms is that projects can be sited further out to sea in deeper waters with stronger wind conditions. Our Bellrock project will be one of the furthest offshore wind farms in the world and this analysis of the seabed composition is crucial in building up our knowledge of what is possible, helping to shape and inform the designs going forward.”

Sudhir Pai, Executive Vice President, Acteon Data and Robotics Division, said: “We are delighted to have supported the Partnership in this groundbreaking work to develop floating wind projects in Scotland.

“Our early involvement provided data interpretation services to help all the teams involved in the project understand the seafloor composition and structure, enabling informed decisions about layout, designs and equipment that will best suit the conditions.”

The data collected by Acteon is now being used to build up a detailed picture of the sites, identifying seabed features and any potential hazards and feeding into a model of the seabed. It will also refine the site boundaries and guide decisions on turbine layouts and the design of the foundations and moorings.

Notes to Editors

 About the BlueFloat Energy | Renantis Partnership

Based in Edinburgh, the Partnership has a 3.3GW portfolio of Scottish floating offshore wind projects – 900 MW Broadshore, 1.2GW Bellrock and the 1GW Stromar project it is developing in collaboration with Ørsted.

In May 2023 it secured exclusivity rights to develop two 99MW projects under the innovation arm of Crown Estate Scotland’s INTOG (Innovation and Targeted Oil & Gas) auction process. The Sinclair and Scaraben projects, located north of Fraserburgh and next to the Partnership’s Broadshore development, will trial innovative foundation technologies, fabrication works and mooring systems with a view to maximising opportunities for the Scottish supply chain, driving local investment and job creation.

The Partnership is developing up to 3GW across two projects in the Celtic Sea – the Petroc wind project off the coast of Devon and Cornwall and the Llewelyn wind project off the coast of Wales.
