Abstract

Floating offshore wind has the potential to unlock renewable power generation at a global scale, but it depends on reliable subsea infrastructure—particularly high-voltage dynamic export cables to allow power transmission from floating substations. Until now, no fully qualified solutions have been available at  sufficiently high transmission voltages. This work describes the successful development and qualification of 145 kV and 245 kV HVAC dynamic export cables designed for floating wind projects. The program combined materials and component testing, large-scale manufacturing trials, and the development of essential supporting technologies such as factory joints and bend stiffeners. Comprehensive qualification campaigns confirmed performance under demanding operational conditions. The outcome represents a significant step forward for the industry: dynamic export cables at transmission level are no longer a future ambition but a deployable technology, helping to accelerate floating wind from demonstration to commercial scale.
