Fred. Olsen 1848 proudly introduces BRUNEL - A pioneering floating foundation to unlock the potential of floating offshore wind

At Fred. Olsen 1848 we are dedicated to develop tomorrow’s energy solutions. The main challenge for floating offshore wind to become industrialized and respond to deployment at scale is the ability to manufacture and assemble floating foundations at a volume that is needed for the floating giga parks. In response, and after several years of development, Fred. Olsen 1848 now launches the Floating Foundation BRUNEL.

The modular design enables BRUNEL to leverage the existing global supply chain and helps create a sustainable industry.

“The design of BRUNEL is based on a simple, yet challenging design philosophy: to see if we can build a foundation based on generic steel tubulars and hence enable manufacturing at commercial scale. This radical focus on commercial requirements, while at the same time attending to excellence on all technical parameters, will allow the floating offshore wind industry to realize its enormous potential.”

Sofie Olsen Jebsen, CEO, Fred. Olsen 1848


Utilize building blocks, with an existing global supply chain, suitable for serial and automized mass production.

  • Prolongs existing lifetime on current manufacturing capacity
  • Size of components favorable for shipping, heavy-duty crane and handling operations
  • Assembly methodology allows for local content maximization 

Building on existing and proven technology, now taken to a new level for deployment in floating offshore wind. Enables: 

  • Low-weight integrated structure
  • Low draft and passive ballast system
  • Low accelerations
  • Strong geographic feasibility
  • Strong scalability potential for WTG & site-specific environment
  • Good hydrodynamic response for carrying a WTG

BRUNEL enters the market at an advanced technological stage, with a final tank test successfully completed at SINTEF Ocean in February 2022. In parallel, BRUNEL successfully received DNV’s statement of feasibility in April 2022. With the tank test and DNV statement of feasibility, BRUNEL has completed a significant milestone to reach Technological Readiness Level 4 (TRL 4).

Fred. Olsen 1848 is determined to make BRUNEL available for commercial use as quickly as possible. Working with SINTEF Ocean, a Physical-Numerical Validation Approach will be applied to demonstrate and qualify BRUNEL according to standard procedures from Oil & Gas and maritime, i.e., exempting the need for piloting and full-scale demonstration. Through this process, BRUNEL will reach TRL 8 at an accelerated pace and will be ready for commercial application within 3 years. Fred. Olsen 1848 will involve leading engineering and fabrication specialists in the process to ensure the requirements of the industry are being addressed; both technically and commercially.

Fred. Olsen 1848 is in close co-operation with customers and other partners to position BRUNEL as the floater of choice for the large scale floating offshore wind farms to be built.

BRUNEL harnesses the advantage of sourcing and procurement from an existing global supply chain. This will de-risk the floating offshore wind projects and offer a high degree of flexibility to maximize the local content footprint, which again will support individual countries’ ability to grow the floating offshore wind industry both domestically and internationally.

BRUNEL also offers a wide range of geographical deployment areas, and scalability to fit the next generation of wind turbines without noticeable changes to the design. In addition, Brunel has a low draft implying flexibility in ports. All this allows for the industry to drive down cost by the use of BRUNEL and to continue to apply optimizations into the supply chain with a view to accelerate the industrialization of floating offshore wind.

An instrumental part of BRUNEL has been to reduce the maintenance requirements, and Fred. Olsen 1848 has a Floating Maintenance Solutions on the way to the market to enhance operations and maintenance activities, including component exchange, at the floating offshore wind site.  Avoiding having to tow the foundations to shore for component exchange, will further drive down the cost of LCOE.

“Brunel is designed for the next generation of wind turbines. With its low LCOE and ability for serial and mass production, we believe the Brunel to be a game-changer that can unlock the potential of floating offshore wind”
