- MPA increases the allowable biofuel blend for Singapore-registered bunker ships from B25 to B30.
- The change takes effect on 7 March 2025.
- Implementation aligns with draft MEPC guidance on biofuel transportation.
- No additional approval needed for Singapore-registered ships within this limit.
- Special approval required for biofuels above B30 or those not listed in IBC Code or MEPC.2/Circ.27.
The Maritime and Port Authority of Singapore (MPA) has announced an increase in the allowable biofuel blend for Singapore-registered bunker ships. Effective 7 March 2025, the limit will be raised from B25 to B30, as stated in an MPA circular released on 6 March 2025, reports Safety4sea.
Alignment with MEPC Draft Guidance
This change follows the draft guidance from the Marine Environment Protection Committee (MEPC) on transporting biofuel blends via conventional bunker ships. The guidance was discussed during the 12th Session of the Sub-Committee on Pollution Prevention and Response (PPR 12) and is set for review and potential approval at the MEPC 83 session in April 2025.
Operational Guidelines for B30 Implementation
Conventional bunker ships can now carry biofuel blends of up to 30% by volume, provided that:
- All residues and tank washings are properly disposed of on land unless the ship’s oil discharge monitoring equipment (ODME) is approved for the biofuel blend.
- These provisions serve as temporary measures until comprehensive biofuel carriage rules are established.
MPA supports this guidance and has enabled early adoption for Singapore-registered bunker ships. No separate approval is required for vessels complying with these regulations.
Compliance and Port State Approval
Shipowners, operators, and crew members of Singapore-registered bunker ships must adhere to these guidelines when handling biofuels with 25% to 30% biofuel content. However, if calling at a foreign port, they must seek approval from the respective Port State Authority.
Special Approval for Higher Biofuel Blends
For biofuels exceeding B30 or those not listed in the IBC Code or MEPC.2/Circ.27, bunker suppliers and operators must obtain approval from MPA’s Standards & Investigation – Marine Fuels (SIMF) department before conducting pilot tests or deliveries. Ongoing pilot programs are available for testing biofuels up to B100.
This regulatory adjustment aligns with Singapore’s commitment to sustainable maritime practices and enhances the country’s position as a leading bunkering hub.
