Based on a holistic approach to floating wind, Fred. Olsen 1848 is developing a complete O&M solution and operational procedure for major component exchange that is optimized for the floating foundation BRUNEL. The BRUNEL Maintenance Solution will enable large component exchange directly at the floating offshore wind site in a safe and cost-efficient manner. This reduces project risk and avoids towing the foundation to shore
Building on the experience and proven track record of Fred. Olsen related companies engaged in both bottom-fixed and floating wind projects, Fred. Olsen 1848 is designing a unique solution that features a barge fitted with both a jacking system and a compatible crane that attaches itself to the BRUNEL foundation. This removes the need for dynamic lifts, reduces complexity in replacement operations, and at the same time creates a working area on the barge to handle the components.
The geometry of BRUNEL, with a dual tower setup, a water depth clearance of ~10 meters above the pontoons, and a large water plane area inside the base triangle of BRUNEL, allows for a jack-up barge to enter from the side of the foundation, towed in by regular tugs, and mobilize for lifting operations.
The barge will jack down and affix on the top of the pontoons. This allows for fast mobilization and enables BRUNEL to remain in operational draft.
