Thai state-owned energy company PTT and Malaysian shipping firm AET, a unit of MISC Group, have signed a memorandum of understanding (MoU) for the development and construction of two zero-emission Aframaxes to be powered by green ammonia, AET said on September 29.

AET said it will select a suitable shipyard and the two zero-emission dual-fuel tankers are to be delivered to PTT for long-term charters in Q4 2025 and Q1 2026, respectively.

“This MoU sets another clear signal of PTT’s and AET’s commitment to reduce greenhouse gas (GHG) emissions from international shipping as energy efficiency improvements alone will not be sufficient,” AET said.
