18,400 TEU Ship - World's Largest Container Ship.

South Korea’s Hyundai Heavy Industries  won a $700 million deal to build the world’s largest container ships for China Shipping Container Lines. Under the deal Hyundia will build five vessels, each capable of carrying 18,400 TEU (20-foot equivalent unit) container boxes.

The ships will break the previous record of  Daewoo Shipbuilding and Marine, which won an order in 2011 to build 20 18,000 TEU container ships for Denmark’s A.P. Moeller-Maersk.
