Samsung Heavy Industries said July 8 it has successfully built the world’s largest container vessel.

The shipbuilder said one of the six 23,000 20-foot equivalent unit-class container ships ordered by Swiss shipper Mediterranean Shipping Co. in September 2017, left its shipyard in Geoje, 400 kilometers southeast of Seoul.

Named MSC Gulsun, the vessel is 400 meters long, 61.5 meters wide and 33.2 meters high, according to the shipbuilder. It can carry 23,756 TEU containers.

Samsung Heavy was the first shipbuilder to produce a container ship with a capacity of over 20,000 TEU after it won an order from Japan’s Mitsui O.S.K. Lines to build four 20,100-TEU vessels in 2015.
