Singapore-based tanker firm AET has placed orders for two LNG dual-fuel Suezmax tankers from South Korea’s Samsung Heavy Industries.

The vessels will feature dual-fuel engines from engine manufacturer Everllence, AET said in a statement on its website on Friday.

AET operates 11 LNG dual-fuel vessels (nine owned and two chartered) and has two more on charter from Singfar.

With these additions, its LNG dual-fuel fleet will rise to 15 vessels, alongside three ammonia dual-fuel newbuilds under construction.

LNG emits less CO2 than conventional marine fuels, but its methane emissions – a potent GHG gas – undermine some of the green credentials of LNG-fuelled ships.

As regulations tighten, bio-LNG is emerging as a potential drop-in alternative that can further lower emissions while using existing LNG infrastructure.

AET has not shared details on when the vessels will be delivered.
