Current rating in dynamic cables with corrugated sheath and double wire armour

Dynamic cables are used to connect offshore, floating wind turbines to upstream networks. To withstand continuous motions from water currents, designs with corrugated metallic sheaths and double wire armour are favoured for enhanced fatigue performance. Their safe and economic operation relies on accurate current rating, linking electromagnetic losses to heat dissipation in surroundings. This paper proposes a fully coupled current rating model, tailored to dynamic cables with corrugated sheaths. A three-dimensional, electromagnetic model accounting for sheath corrugation and double wire armouring is developed, employing the
