On 17 October, Maersk, Golden Island Pte Ltd, and PSA completed the world's largest single ethanol bunkering operation at Pasir Panjang Terminal. The Singapore-flagged dual-fuel container ship Maersk Halifax received approximately 5,000 tonnes of ISCC-certified bioethanol from Golden Island's Singapore-registered IMO Type II chemical tanker Golden Centaurus, with the transfer carried out simultaneously with container cargo operations. It was Singapore's first ethanol bunkering and the first ethanol fuel trial on a retrofitted vessel in Maersk's fleet.</span></p><p class="ds-markdown-paragraph" style="margin: 16px 0px; color: rgb(15, 17, 21); font-family: quote-cjk-patch, Inter, system-ui, -apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Oxygen, Ubuntu, Cantarell, &quot;Open Sans&quot;, &quot;Helvetica Neue&quot;, sans-serif; font-size: 16px;"><span class="">The significance of the operation lies less in the volume than in the operational model it validated. The bunkering was measured using mass flow meters and conducted concurrently with terminal container operations (SIMOPS), demonstrating that alternative fuel supply can be delivered without disrupting normal terminal activity. For any port pursuing fuel transition, whether a new fuel can be embedded into existing operational flows — rather than requiring separate windows and facilities — is the key precondition for scaling. Singapore's answer is affirmative.</span></p><p class="ds-markdown-paragraph" style="margin: 16px 0px; color: rgb(15, 17, 21); font-family: quote-cjk-patch, Inter, system-ui, -apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Oxygen, Ubuntu, Cantarell, &quot;Open Sans&quot;, &quot;Helvetica Neue&quot;, sans-serif; font-size: 16px;"><span class="">The MPA stated explicitly that data from the operation will be used to assess how to extend Singapore's existing methanol bunkering technical reference standard, TR 129, to cover ethanol. Ethanol shares operational characteristics with methanol and can be used in methanol-compatible engines with necessary modifications. This means Singapore's accumulated infrastructure, safety protocols, and crew training experience in methanol can potentially be reused for ethanol at lower cost, accelerating the institutionalisation of a second alcohol-based fuel.</span></p><p class="ds-markdown-paragraph" style="margin: 16px 0px; color: rgb(15, 17, 21); font-family: quote-cjk-patch, Inter, system-ui, -apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Oxygen, Ubuntu, Cantarell, &quot;Open Sans&quot;, &quot;Helvetica Neue&quot;, sans-serif; font-size: 16px;"><span class="">From the shipowner's perspective, Maersk's intent is clear. Emma Mazhari, the company's head of energy markets, said: "The energy transition requires us to explore and scale solutions that deliver real impact. Maersk continues to pursue a multi-fuel strategy because we recognise that no single fuel pathway alone can decarbonise global shipping." The statement continues Maersk's long-standing position of not betting on a single technology route but accumulating operational experience across multiple fuels. Earlier this year, Maersk completed ethanol trials on Laura Maersk, Antonia Maersk, and Tangier Maersk.</span></p><p class="ds-markdown-paragraph" style="margin: 16px 0px; color: rgb(15, 17, 21); font-family: quote-cjk-patch, Inter, system-ui, -apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Oxygen, Ubuntu, Cantarell, &quot;Open Sans&quot;, &quot;Helvetica Neue&quot;, sans-serif; font-size: 16px;"><span class="">Safety and operational readiness underpinned the successful execution. Prior to the operation, participants conducted a Hazard and Operability (HAZOP) study, and the MPA worked with stakeholders to ensure crew received training in fuel handling and emergency response, drawing fully on prior methanol bunkering experience. Johnny Tan, managing director of Golden Island, emphasised that its crew and the Golden Centaurus "built on the lessons learned from methanol bunkering, following the same safety-first discipline," enabling them to "deliver the largest single ethanol bunkering to date safely and on schedule."</span></p><p class="ds-markdown-paragraph" style="margin: 16px 0px; color: rgb(15, 17, 21); font-family: quote-cjk-patch, Inter, system-ui, -apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Oxygen, Ubuntu, Cantarell, &quot;Open Sans&quot;, &quot;Helvetica Neue&quot;, sans-serif; font-size: 16px;"><span class="">From a port competition standpoint, the operation widens the gap between Singapore and other alternative fuel bunkering hubs. While many ports are still debating whether and when to build methanol or ammonia bunkering capacity, Singapore is already testing the feasibility of extending its methanol infrastructure to ethanol — and doing so through actual operations rather than feasibility studies. Nelson Quek, regional CEO of PSA Southeast Asia, said the operation "marks an important step in our operational readiness for a broader range of low-carbon fuel options."</span></p><p class="ds-markdown-paragraph" style="margin: 16px 0px; color: rgb(15, 17, 21); font-family: quote-cjk-patch, Inter, system-ui, -apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Oxygen, Ubuntu, Cantarell, &quot;Open Sans&quot;, &quot;Helvetica Neue&quot;, sans-serif; font-size: 16px;"><span class="">Looking ahead, the key question is whether ethanol can move from a one-off demonstration to routine supply. Maersk has not disclosed the cost of the bunkering or a timeline for regular ethanol use on Maersk Halifax. Ethanol's appeal as a marine fuel lies in its existing global production and distribution network, but marine-grade certification, engine compatibility, and the reliability of port bunkering infrastructure still need to be verified item by item. Singapore's operation provides an operational data point, but two barriers remain before ethanol becomes a standard bunkering option at major Asian ports: institutional framework development and commercial viability.</span></p>
