Shore Power - Required Cable Size

Shore-connection cable size for high-voltage ship-shore power per ISO/IEC/IEEE 80005-1 - based on load current and cable derating for parallel runs.

Formula, assumptions, and limits

HVSC standardised at 6.6 or 11 kV (AC) for most segments. Cruise and container ships typically need 10 MW+. Apply cable derating factors per IEC 60287 for trefoil vs flat formation.
