- Singapore introduced TR 136 to standardize charging and battery swap systems for electric harbour craft (e-HC).
- The framework ensures safety, interoperability, and alignment with global standards.
- TR 136 creates business opportunities in charging infrastructure, battery tech, and workforce upskilling.
- MPA and EnterpriseSG are driving adoption through industry engagement and green financing schemes.
Singapore has introduced Technical Reference (TR) 136, a framework designed to standardize the development of charging infrastructure and battery swap systems for electric harbour craft (e-HC). Developed by the Maritime and Port Authority of Singapore (MPA) and Enterprise Singapore (EnterpriseSG) through the Singapore Standards Council (SSC), the initiative supports Singapore’s broader maritime decarbonization strategy.
Safety and Technical Standards
TR 136 defines safety protocols to protect personnel and property from electrical and mechanical hazards during installation and operation. It also establishes technical interoperability requirements, ensuring consistency across different charging and battery swap systems. The framework aligns with internationally recognized electric vehicle charging standards such as the IEC 61851 and IEC 62840, while integrating local regulations, including TR 25 for electric vehicle charging systems.
Industry Impact and Adoption Benefits
The adoption of TR 136 is expected to enhance industry confidence by assuring shipowners, port operators, and charging providers of a standardized, safe operational environment. The framework also presents new business opportunities in the charging infrastructure and battery technology sectors, alongside workforce upskilling prospects in maritime electrification.
Development and Stakeholder Involvement
The standard was formulated by the Working Group (WG) on Electric Harbour Crafts Charging System, under the oversight of the Electrical and Electronic Standards Committee (EESC). The WG includes government representatives, charging equipment manufacturers, e-HC developers, testing and certification agencies, and academic institutions.
MPA Chief Executive Mr. Teo Eng Dih highlighted TR 136 as a key step in fostering a robust and interoperable charging network, while EnterpriseSG Director-General Ms. Choy Sauw Kook emphasized the role of standards in accelerating maritime electrification. WG Co-Convenors Er. Lim Say Leong and Mr. Ng Bingrong underscored the extensive consultation process and the ongoing need for stakeholder feedback.
Driving Industry Adoption and Financial Support
To encourage uptake, MPA and EnterpriseSG will hold a closed-door seminar on March 28, 2025, during Singapore Maritime Week 2025. The event will feature insights from MPA, the Working Group, and industry experts, with discussions on technical challenges and market adoption.
Additionally, MPA hosted a business-matching event on March 10, 2025, to connect e-HC developers, charging infrastructure providers, investors, and insurers. Financing options are available through the Enterprise Financing Scheme-Green (EFS-Green), which offers up to 70% risk-sharing with seven participating financial institutions. Major banks, including DBS, OCBC, and UOB, have also signaled interest in supporting e-HC financing solutions.
As Singapore pushes forward with maritime electrification, TR 136 provides a structured foundation for the industry to transition towards sustainable and efficient harbour craft operations.
