Singapore-based tanker operator AET has signed shipbuilding agreements with South Korea's Samsung Heavy Industries for the construction of two LNG dual-fuel Suezmax tankers.

The vessels will expand AET's dual-fuel fleet and enable the company to operate dual-fuel capability across all tanker sectors — Aframaxes, shuttle tankers, Suezmaxes, and very large crude carriers (VLCCs).

Each vessel will feature an Everllence 6G70ME-C10.5-GI main engine, designed for fuel efficiency and to minimize methane slip. The tankers will also be equipped with SVESSEL Intelligent Smart Ship Solution, enabling real-time monitoring and data-driven optimization of performance and safety.

Additional features include SAVER Stator-D (Duct), SARB (Rudder Bulb), and SAVER-Fins to enhance hydrodynamic efficiency and reduce fuel consumption, as well as variable frequency drive systems and a hybrid vertical bow design designed to further improve propulsion efficiency and lower emissions.

LNG is one of several alternative fuel pathways AET is pursuing, alongside ammonia and other emerging low-carbon fuels, as part of its Energy Transition Strategy.

Referring to data in a 2021 study by SEA-LNG and SGMF/Sphera, AET noted that, when operating on LNG, dual-fuel vessels can emit between 14% to 23% less greenhouse gases on a well-to-wake basis than those using conventional marine fuels, while significantly reducing particulate matter, sulphur oxides, and nitrogen oxides.

"LNG from alternative feedstocks namely Bio-LNG and e-LNG offer a long-term and scalable solution to deep decarbonisation for the industry. These forms of LNG while nascent in their use as marine fuel offer significant incremental GHG emissions savings beyond (fossil) LNG based savings and utilise the same infrastructure," AET stated, citing Lloyd's Register's 'Fuel for Thought: LNG' 2025 report.

Nick Potter, president and CEO of AET, said: "This marks another important step in building a more sustainable fleet and supporting our customers' decarbonization ambitions. With these newbuilds, our dual-fuel fleet will grow to 18 vessels, a clear demonstration of the progress we're making in delivering more energy with less emissions.

"Through continued collaboration with industry partners, we're investing in technologies that deliver lower-carbon energy solutions today while keeping firmly on course towards a 40% reduction in greenhouse gas emissions intensity by 2030 as part of our Energy Transition Strategy."

AET currently operates 11 LNG dual-fuel vessels—nine owned and two in-chartered—and has two newbuilds in-charter with Singfar. The addition of these two newbuilds will bring the total to 15 LNG dual-fuel vessels in AET's fleet, with a further three ammonia dual-fuel newbuilds underway.

Headquartered in Singapore, AET has commercial and operational offices in Brazil, Malaysia, Norway, UK, US and Uruguay. The company is a wholly-owned subsidiary of Malaysian energy logistics group MISC Berhad.
