Singapore | November 7, 2025 – AET, a leading global owner and operator of crude and product tankers, has announced a major step in its decarbonisation journey with new shipbuilding contracts signed with Samsung Heavy Industries (SHI) for two Liquefied Natural Gas (LNG) dual-fuel Suezmax tankers.
This strategic investment strengthens AET’s commitment to cleaner shipping solutions and expands its dual-fuel fleet operating globally. With these new additions, AET will achieve dual-fuel capability across all major tanker segments – Aframax, Shuttle Tanker, Suezmax, and VLCC, underscoring its role in supporting the maritime sector’s transition toward lower-carbon operations and global net-zero goals.

Technology & Environmental Performance
The new Suezmax tankers incorporate advanced energy-efficient technologies designed to maximise performance and minimise emissions:
- Main Engine: Fitted with the Everllence 6G70ME-C10.5-GI main engine, optimised for high fuel efficiency and reduced methane slip.
- Smart Ship Systems: Integration of the SVESSEL Intelligent Smart Ship Solution enables real-time performance monitoring, data-driven optimisation, and enhanced safety.
- Hydrodynamic Design: Energy-saving features include SAVER Stator-D (Duct), SARB (Rudder Bulb), and SAVER-Fins to reduce fuel consumption.
- Propulsion Efficiency: The ships will employ Variable Frequency Drive (VFD) systems and a hybrid vertical bow to improve propulsion efficiency and cut emissions.
LNG and Alternative Fuels Strategy
LNG is a cornerstone of AET’s broader Energy Transition Strategy, which also encompasses ammonia and other emerging low-carbon fuels.
- GHG Reduction: When operating on LNG, these dual-fuel vessels are designed to emit between 14% to 23% less greenhouse gases (GHG) on a well-to-wake basis compared to vessels using conventional marine fuels. They will also achieve significant reductions in particulate matter (PM), sulphur oxides (SOₓ), and nitrogen oxides (NOₓ).
- Deep Decarbonisation: The design allows for future flexibility to transition to alternative LNG feedstocks, namely Bio-LNG and e-LNG. These scalable solutions offer incremental GHG emissions savings beyond fossil-based LNG, utilising the same existing bunkering infrastructure.
AET’s Growing Dual-Fuel Fleet
This order accelerates AET’s fleet expansion in the lower-emission segment. Nick Potter, President & CEO of AET, commented “This marks another important step in building a more sustainable fleet and supporting our customers’ decarbonisation 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.”
Nick Potter further noted AET’s long-term goals “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.”
Fleet Snapshot
AET’s dual-fuel fleet will soon comprise 15 LNG dual-fuel vessels (including these new Suezmaxes and chartered ships) and three ammonia dual-fuel newbuilds currently under construction. AET’s overall fleet now exceeds 60 vessels.
AET is a wholly owned subsidiary of MISC Berhad, committed to achieving net-zero emissions by 2050.
