CARRIAGE OF BLENDS OF BIOFUELS AND MARPOL ANNEX I CARGOES BY CONVENTIONAL BUNKER TANKERS IN THE PORT OF SINGAPORE
This circular serves to update all bunker suppliers and bunker craft operators licensed by the Maritime and Port Authority of Singapore (MPA) on the latest requirements to the carriage of biofuel blends and MARPOL Annex I Cargoes by conventional bunker tankers in the Port of Singapore.
2 With reference to Shipping Circular No. 01 of 2025, the draft Interim guidance on the carriage of blends of biofuels and MARPOL Annex I cargoes by conventional bunker ships has been accepted by the MPA for early implementation on board Singapore registered conventional bunker vessels with effect from 07 March 2025.
3 In line with the above decision, licensed bunker tankers1 operating in the Port of Singapore will be allowed to carry and deliver biofuels2 up to B30 with effect from 07 March 2025. There is no requirement to seek MPA’s separate approval.
4 For marine biofuel blends of up to B30, bunker suppliers and bunker craft operators are reminded to ensure adequate technical and operational risk assessments are conducted and mutually agreed between buyer and seller prior to the delivery.
5 For the supply of marine biofuels above B30 or biofuels not listed in chapters 17 and 18 of the IBC code or the MEPC.2/Circ.27 (Annex 11), bunker suppliers and bunker craft operators are required to seek approval from MPA’s Standards & Investigation – Marine Fuels (SIMF) department prior to these pilots and delivery. Pilots of up to B100 are on-going and bunker suppliers can engage in these pilots to test the efficacy and processes.
