The Maritime and Port Authority of Singapore (MPA) on Thursday (6 March) issued Port Marine Circular No. 1 of 2025 regarding a draft Marine Environment Protection Committee (MEPC) circular on biofuels which sets out conventional bunker ships may transport blends of not more than 30% by volume of biofuel (≤B30):

INTERIM GUIDANCE ON THE CARRIAGE OF BLENDS OF BIOFUELS AND MARPOL ANNEX I CARGOES BY CONVENTIONAL BUNKER SHIPS AS AGREED BY 12th SESSION OF THE SUB-COMMITTEE ON POLLUTION PREVENTION AND RESPONSE (PPR 12)

This circular draws your attention to the draft MEPC circular on the Interim guidance on the carriage of blends of biofuels and MARPOL Annex I cargoes by conventional bunker ships agreed by 12th Session of the Sub-Committee on Pollution Prevention and Response (PPR 12)

The draft MEPC circular is to be deliberated for approval by the 83rd session of Marine Environment Protection Committee (MEPC 83).

The draft MEPC circular sets out that conventional bunker ships may transport blends of not more than 30% by volume of biofuel (≤B30) as long as all residues or tank washings are discharged ashore unless the oil discharge monitoring equipment (ODME) is approved for the biofuel blend(s) being shipped while pending further development of carriage requirements on biofuels for conventional bunker ships certified for carriage of oil fuels under MARPOL Annex I or the revision of the current carriage requirements as provided in the IBC Code and circular MSCMEPC.2/Circ.17.

Various pilots have been undertaken by industry and MPA in Singapore. MPA has participated actively in the draft MEPC circular on the Interim guidance on the carriage of blends of biofuels and MARPOL Annex I cargoes by conventional bunker ships as agreed by PPR 12. MPA accepts this draft for early implementation on board Singapore registered conventional bunker ships with effect from 07 March 2025 onwards. There is no requirement to seek MPA’s separate approval.

Shipowners, ship managers, operators and masters of Singapore-registered conventional bunker ships are hereby reminded to comply with the draft MEPC circular and to obtain approval from the competent Port State Authority before calling at a foreign port for operations with blends containing more than 25% but not more than 30% by volume of biofuel (>B25 to ≤B30) onboard.

For the use 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 to shipowners, ship managers and operators. Pilots for up to B100 are on-going, and vessels can engage in these pilots to test the efficacy and procedures.

Any queries relating to this circular should be directed to MPA Shipping Division via email at [email protected].

MPA and MSC ink MoU to support adoption of alternative bunker fuels

The Maritime and Port Authority of Singapore (MPA) on Wednesday (3 June) said it signed a Memorandum of Understanding (MoU) with MSC Mediterranean Shipping Company to strengthen collaboration in maritime decarbonisation, digitalisation, innovation, and manpower development. 

The MoU was signed on 25 May 2026 by Mr Ang Wee Keong, Chief Executive of MPA, and Mr Soren Toft, Chief Executive Officer of MSC.

The MoU underscores the shared commitment of MPA and MSC to foster a sustainable, digital, and future-ready maritime sector, while enhancing MSC’s operational and business activities in Singapore. This year also marks the 30th anniversary of MSC establishing its Asia Regional Office and local office in Singapore.

Under the MoU, MPA and MSC will explore new routes and services to strengthen connectivity, support the adoption of alternative marine fuels such as bio-LNG, and advance technologies to improve vessel energy efficiency and operational performance.

MPA and MSC will also collaborate on maritime digitalisation initiatives to improve operational efficiency, including streamlining vessel arrivals and port operations. 

On manpower development, MSC will support internship and scholarship opportunities through Singapore Maritime Foundation’s Maritime Outreach Network (MaritimeONE) platform, an industry-led tripartite partnership comprising industry, government and institutes of higher learning that aims to raise awareness of the maritime industry and attract quality talent into the maritime sector.

Mr Ang Wee Keong, Chief Executive of MPA, said: “This partnership reflects the strong collaboration between MPA and MSC in driving sustainability and digitalisation in the maritime sector. By working together on decarbonisation, operational efficiency and talent development, we aim to strengthen Maritime Singapore’s position as a trusted and future-ready global maritime hub.”

Mr Soren Toft, Chief Executive Officer of MSC, said: “Singapore is a strategically important hub for MSC and a key gateway to the broader Asia region. As we mark 30 years in Singapore, this MOU reinforces our long-term commitment to strengthening our presence here. MSC and Singapore are closely aligned on the priorities shaping the future of global shipping, and we look forward to deepening this partnership to drive the continued growth and resilience of the maritime industry.”

BHP and GCMD trial multi-feedstock B100 bio bunker fuel on bulk carrier

BHP and the Global Centre for Maritime Decarbonisation (GCMD) on Wednesday (3 June) said they have blended biofuels from two distinct feedstocks—used cooking oil and waste animal fats —and introduced the lower-emissions marine fuel into a BHP-chartered bulk carrier as part of a pilot project.

The bio-blend in the BHP and GCMD pilot is being used on a BHP-chartered bulk carrier Berge Lyngor, owned and operated by Berge Bulk, transporting BHP iron ore from Western Australia to China. When run on bio-blend, the vessel has the potential to reduce well-to-wake greenhouse gas emissions by approximately 79 per cent per voyage compared to sailing on very low sulphur fuel oil (VLSFO).

The vessel bunkered in Singapore in early May with a B100 bio-blend comprising 50 percent tallow-derived biodiesel, sourced and supplied by HAMR Energy, and 50 per cent used cooking oil (UCOME) supplied by Mitsui & Co Energy Trading Singapore (METS).

Mitsui also blended the fuel and Dan-Bunkering coordinated and executed the bunkering operation, which was performed by Global Energy’s barge MT Maple.

The BHP and GCMD pilot will assess how biofuels from multiple feedstocks can be blended, handled, and introduced under real-world operating conditions using existing used cooking oil bunkering infrastructure.

At the same time, insights from this pilot will help identify solutions to challenges related to fuel quality, handling, traceability, and onboard vessel performance.

Biofuels for global shipping today rely heavily on used cooking oil – a feedstock whose availability is approaching its projected limits. Biofuel from waste animal fats presents a promising option to expand the supply of lower-emissions marine fuels.

The outcomes of the pilot are expected to shed light on the practical steps to integrate biofuel blends from different feedstocks into existing supply chains. The diversity of biofuels will provide shipowners and operators with greater flexibility to optimise fuel procurement based on cost, availability, and lifecycle emissions performance.

Biofuels derived from different feedstocks can exhibit varying properties that may impact operations, including potential corrosion from oxidation, fuel system clogging caused by wax formation, which this pilot aims to assess.

The pilot will trace and verify the biofuel blend’s integrity aimed at bolstering confidence in emissions reductions reporting. The pilot will also provide insights into how robust tracing can support future marine fuel supply chains where biofuels from multiple feedstocks with varying lifecycle greenhouse gas emissions footprints are blended together.

This project is co-funded by the Maritime and Port Authority of Singapore under the Maritime Innovation and Technology Fund (MINT).

NYK starts one-year B100 bio bunker fuel trial on car carrier

Japanese shipping firm NYK on Tuesday (2 June) said it has commenced a one-year long-term trial involving the continuous use of 100% biofuel (B100) on an NYK-operated car carrier. 

In this trial, NYK will operate a car carrier continuously on B100 for one year to evaluate the impact on engines, fuel supply systems, and operational practices. High-purity biofuels such as B100 are known to be susceptible to degradation from oxygen, light, and heat, raising concerns about the stability of such fuels during long-term use.

In this trial, the biofuel primarily comprises FAME (Fatty Acid Methyl Ester) derived from used cooking oil and similar feedstocks.

The initiative is designed to evaluate the fuel’s effects on the vessel’s equipment and verify operational safety under real-world conditions. 

Through this effort, NYK seeks to accumulate technical expertise that will support the broader use of high-purity biofuels and further accelerate efforts to reduce greenhouse gas (GHG) emissions.

NYK has been advancing the use of biofuels through various initiatives. In 2024, the company conducted a trial using biofuel blend B24 and subsequently expanded practical usage to B30. However, the company said there remains limited global experience with the long-term continuous use of B100.

“By collecting long-term operational data through this trial, NYK aims to accumulate valuable technical insights to support both the safe operation of vessels and the wider adoption of high-purity biofuels,” it said.
