- Revised “Electric Propulsion Vessel Standards” become effective 29 May 2025, introducing requirements for fuel-cell–powered ships, core system redundancy, and enhanced fire safety in battery rooms.
- The amendments allow non-explosion-proof electrical equipment under specific safety measures and permit waiving risk assessments for vessels identical in design.
- These changes aim to align regulations with real-world operational needs and encourage broader adoption of next-generation electric propulsion amid tougher GHG requirements.
First established in 2020, the “Electric Propulsion Vessel Standards” have facilitated the development and operation of over 50 electric and hybrid vessels across South Korea. In response to more stringent global and domestic greenhouse gas regulations, the Ministry of Oceans and Fisheries revised these standards to further promote next-generation electric propulsion technologies and enhance onboard safety. The updated regulations take effect on 29 May 2025.
Key Technical Requirements
- Fuel-Cell and Portable Power Source Integration
The revised standards extend coverage to ships powered by fuel cells and other portable power sources, acknowledging emerging technologies beyond conventional battery systems. - Redundancy for Core Electric Propulsion Systems
To boost reliability, vessels must now incorporate redundant configurations for critical electric propulsion components. This ensures continued operation even if a primary system fails. - Battery Room Fire Safety Enhancements
Battery spaces must be equipped with gas detectors and dedicated fire extinguishers, enabling rapid response in the event of a battery fire. Automatic power shutdown systems are also required to isolate electrical faults.
Practical Flexibilities and Clarifications
- Risk Assessment Waivers for Identical Vessels
Vessels sharing the same design no longer need individual risk assessments, reducing duplication of effort and expediting approval for series-built electric ships. - Conditional Use of Non-Explosion-Proof Equipment
Under the updated rules, non-explosion-proof electrical equipment may be installed in certain areas—such as battery rooms—provided that automatic power shutdown mechanisms are in place to isolate faults and prevent fire propagation.
Alignment with Operational Realities
By incorporating these technical and safety updates, the Ministry aims to better match regulatory requirements with actual vessel operations. The new rules are designed to remove unnecessary barriers, encourage innovation in electric propulsion, and ensure that safety standards keep pace with evolving technology.
Expected Impact
Shipbuilders and operators can anticipate smoother certification processes for electric- and fuel-cell–driven vessels, plus greater confidence in system reliability. The practical flexibilities—such as design-based risk-assessment waivers—should accelerate fleet expansion, while enhanced safety provisions will help prevent and mitigate battery-related incidents. Collectively, these revisions support South Korea’s broader goal of reducing maritime GHG emissions and fostering advanced, zero-emission shipping solutions.
