Gas Agility is the world largest liquefied natural gas (LNG) bunkering vessel. It is also the first in a series of two ships to be constructed for Emerald Green Maritime at the Hudong Zhonghua Merhant Marine Mitsui.
The Gas Agility is equipped with Gaztransport & Technigaz's Mark3 flex membrane containment system built at Hudong–Zhonghua Shipbuilding in China near Shanghai. It is also fitted with innovative tank technologies such as the complete reliquefaction of boil-off gas to achieve zero vaporised gas loss. Gas Agility is owned by EGML, a wholly owned subsidiary of MOL, and chartered by Total's affiliate Total Marine Fuels Global Solutions (TMFGS). Construction started in China in November 2018 at Hudong–Zhonghua Shipbuilding's yard and delivered in April 2020. The vessel operated in Northern Europe where it would supply LNG to commercial ships including CMA CGM's nine ultra large container vessels (ULCVs) for a period of at least ten years.
