Kongsberg Maritime study highlights strong potential for fully electric RoPax vessels across key European routes

A recent study by Kongsberg Maritime identifies significant potential for fully electric RoPax vessels across Northern European short-sea corridors. By analyzing operational data from busy routes connecting ports like Oslo, Kiel, and Copenhagen, the research demonstrates that battery-powered propulsion can effectively replace traditional heavy fuel oil systems. This transition supports the broader decarbonization goals of the maritime industry, offering a sustainable alternative for high-frequency ferry operations while maintaining the rigorous performance standards required for passenger and freight transport.

The adoption of fully electric propulsion systems necessitates strict adherence to the International Convention for the Safety of Life at Sea (SOLAS), specifically Chapter II-1 regarding machinery and electrical installations. Furthermore, compliance with the International Code of Safety for Ships using Gases or other Low-flashpoint Fuels (IGF Code) and relevant DNV or Lloyd’s Register class notations is mandatory for battery-integrated vessels. Operations and compliance departments must ensure that energy storage systems meet rigorous fire safety standards and thermal management protocols to satisfy port state control inspections and environmental regulations under MARPOL Annex VI.

This shift toward electrification will significantly impact the daily responsibilities of chief engineers and second engineers. These technical officers must now prioritize advanced training in high-voltage power management, battery health monitoring, and complex electrical diagnostics. As these vessels become more prevalent, engine ratings will also require specialized certification to safely maintain and troubleshoot lithium-ion energy storage systems, ensuring that onboard safety protocols remain robust during charging cycles and peak load operations at port.
