An LNG bunker tank has been lifted into a Hapag-Lloyd containership in what is the world’s first retrofit of large boxship to allow the vessel to run on natural gas.

The 6,700-cbm, membrane-type bunker tank was lifted onto the 15,000-teu Sajir (built 2014) at Hudong-Zhonghua Shipbuilding (Group)-controlled Huarun Dadong Dockyard in Shanghai.
