China's self-developed liquefied natural gas (LNG) dual-fuel container vessel was delivered on Monday in northeast China's port city of Dalian. The vessel "Maria Cristina" has a capacity of 16,000 TEUs. Equipped with a 13,000-cubic-meter Type B LNG fuel tank, the vessel is the world's largest Type B LNG fuel tank container ship. It is the first time China has independently developed the entire process of building a Type B LNG fuel tank.
