DNV issues certifications for floating offshore wind foundation concept

Fred. Olsen 1848 says the BRUNEL Floating Foundation initiative for the floating offshore wind sector has completed its comprehensive basic design phase.

This was done in compliance with the DNV-SE-0422 certification, and the development subsequently gained a DNV Basic Design Certification.

These milestones are said to confirm acceptance for the design methodologies and developments for primary steel design, secondary steel, mooring, manufacturing, assembly and integration, logistics, transportation, and installation, and the operations and maintenance philosophies.

According to Fred Olsen, the BRUNEL design provides flexibility in secondary steel and outfitting for installation and hookup procedures offshore, fulfilling the requirements of legislative bodies and project developers.

The company has built up a close collaboration with tubular manufacturers, turret specialists and high-voltage swivel developers to support project integration and optimization:

• Ramboll has been working as an independent engineering consultant for BRUNEL Floating Foundation, performing engineering of the basic design certification;
• Seasystems has provided mooring and turret technologies;
• MOOG Focal is supplying the high-voltage swivels; and
• 7Waves is assisting with the primary steel design.
