Özet

The European Green Deal and the IMO’s medium and long-term strategies for the reduction of greenhouse gas (GHG) emissions have stimulated the development and implementation of technical solutions aimed at mitigating emissions originating from maritime transport. In line with the net-zero carbon emission targets in the maritime sector, the use of hybrid and fully electric ship technologies has been rapidly increasing. Within this context, Shore-Side Electricity (SSE) and Shore-Side Battery Charging (SBC) systems have become increasingly prevalent as key components of sustainable energy management frameworks designed to eliminate greenhouse gas and air pollutant emissions in port operations.

This study investigates the main failure modes and safety requirements associated with shore-based charging systems for hybrid and fully electric ships through a risk-based assessment approach. The evaluation encompasses cable and connector systems, grounding and insulation, energy management, thermal control, communication infrastructure, human factors, and fire and gas-related hazards. The findings indicate that the primary risk areas with high likelihood-high impact combinations include voltage fluctuations, grounding and insulation failures, overcurrent, cable and connector damage, and ship-to-shore communication disruptions. Such conditions may lead to electrical fires and explosions, electric shock and arc flash injuries for personnel, as well as energy interruptions on board or at the port during the charging process. The results reveal that ensuring safe and uninterrupted operation in shore electrification applications requires appropriate system design, well-defined operational procedures, comprehensive personnel training, and effective ship-shore coordination mechanisms. The study contributes to the development of safety-oriented policies and practices for port authorities, ship operators, and engineering stakeholders in the implementation of shore power supply systems.
