Floating power platforms for mobile cold-ironing

Abstract

The colloquial term ‘cold-ironing’ refers to the shore power connection when a ship is at berth. Even though, cold-ironing is not new to the shipping industry only recently it received more attention, mainly due to strict emission regulations. When a ship receives shore power, its emissions can be eliminated and thus cold-ironing is becoming a popular service sought by ships that berth at emission controlled ports. Generally, the shore power connection is available only at berth and thus emissions from the ships that are anchored in and around the port is still a significant issue. This paper proposes a floating power platform for ‘Mobile Cold-ironing’ of anchored ships. In the proposed system, a fuel cell — battery hybrid system is used as the source. Efficacy of the proposed system in supplying dynamic loads is verified with simulation results.
