Validation

Independent third-party validation of the CLS Wind platform across loads, structures, and the maritime regulatory regime, with Letters of Support from offshore wind developers operating in the relevant markets.

Independent load modeling

• Arup. Fixed offshore. 15 MW reference turbine. Load modeling above and below the transition piece, validated against real project data.
• Kent Engineering. Floating offshore. 15 MW three-column semi-submersible. Loading, fit, load transfer, and wind effects.

Approval in Principle

The American Bureau of Shipping issued an Approval in Principle for the CLS Wind 15 MW offshore wind turbine system in May 2024, after roughly nine months of review. ABS is the world's leading maritime classification society.

Letters of Support

Offshore wind projects backing CLS Wind technology in the relevant markets:

• Muir Mhor Offshore Wind Farm
• Ossian Offshore Wind Farm
• Buchan Offshore Wind Farm

Site-specific onshore designs

Reference designs delivered for the following platforms, each with independent verification of the lift envelope and component loads:

• 2.7 MW Siemens Gamesa
• 4.2 MW Vestas
• 6.1 MW GE Vernova

The principle being validated

Loads travel from the elevating platform through CLS Wind structural chords into the foundation, monopile, or floater. The existing tower is not in the load path; it sees only a stabilizing connection at its strongest point. This is why the same platform principle works for new build, retrofit, and major component replacement, and why the validation done for a new tower applies to an in-service tower of comparable geometry.
