Golden Island has completed what reports describes as the world’s largest ethanol bunker stem, delivering about 5,000 mt of ISCC-certified bio-ethanol to a Maersk container ship in Singapore on 19 October 2026.
The operation saw the company’s IMO Type II chemical tanker Golden Centaurus supply the dual-fuel container ship Maersk Halifax while the latter’s containers were being handled. Sources indicated that the transfer used a mass flow meter for the delivery.
Golden Island’s delivery has been identified as Singapore’s first ethanol bunkering of this type. The transfer of roughly 5,000 mt of ISCC-certified bio-ethanol marks a notable scale for biofuel bunkering in the port state described in the report.
The transfer was carried out while cargo operations continued on board Maersk Halifax, indicating the bunkering was conducted alongside concurrent container handling. According to the report, a mass flow meter was used to register and control the quantity supplied during the operation.
Operation details
reports set out that Golden Centaurus acted as the fuel supplier, employing its certification and tank configuration as an IMO Type II chemical tanker to deliver the ethanol. The receiving ship was identified as Maersk Halifax, a dual-fuel container vessel, which took on the ISCC-certified bio-ethanol during port operations.
The volume supplied was reported as about 5,000 mt, and the fuel was described as ISCC-certified bio-ethanol. A mass flow meter was used in the transfer, a detail noted in the coverage to indicate metered measurement of the fuel quantity.
Significance and context
The report framed the delivery as Singapore’s first operation of its kind, and characterised the stem as the world’s largest ethanol bunkering to date. Those two points were the principal broader claims noted in the item published on 19 October 2026.
Golden Island and Maersk are the two companies explicitly named in the report, and the vessels Golden Centaurus and Maersk Halifax are the ships identified as supplier and recipient respectively. The factual notes provided do not supply further technical, commercial or regulatory detail beyond the measures and descriptions already set out.
The use of ISCC-certified bio-ethanol and a mass flow meter were the operational elements highlighted in the report. Beyond the immediate account of the transfer, the supplied facts do not record statements from the companies involved or offer additional commentary on follow-up plans or wider industry implications.
Overall, the account from reports presents a single, discrete occurrence: Golden Island’s Golden Centaurus supplied about 5,000 mt of ISCC-certified bio-ethanol to Maersk Halifax in Singapore on 19 October 2026, using metered transfer while containers were being handled, and the report described the delivery as the world’s largest ethanol bunker stem and a first for Singapore.
