Gas Agility has arrived in Rotterdam's anchorage. But for the moment, the vessel has not yet notified the Harbour Master of an upcoming call.

According to its owner Mitsui O.S.K. Lines (MOL), the 135.5-metre-long ship ranks as "the world's largest LNG bunkering vessel".

The ship was built at the shipyard of Hudong-Zhonghua Shipbuilding near Shanghai and is operated by the French company Total. It will mainly be active in Northern Europe.

For the next decade at least, Gas Agility will be supplying LNG to sea-going vessels, including CMA CGM's nine new Ultra Large Container Vessels (ULCVs).

These are the first 23,000-TEU container vessels to be powered by LNG (liquefied natural gas).
