Taiwan-based shipping major Evergreen has approved orders of a total of ten 23,000 TEU containership giants at three shipyards in South Korea and China.

Namely, six units would be built by South Korea’s Samsung Heavy Industries, while two each would be constructed at China’s Jiangnan Shipyard and Hudong Zhonghua Shipbuilding.

Evergreen said that the value of the entire order stands between USD 1.4 billion and USD 1.6 billion. The company opted for the move as part of its fleet optimization plans.

The first of the giant ships, which will have the capacity of 23,000 twenty-foot equivalent units (TEUs), is likely to enter service in 12 to 18 months’ time.

According to Alphaliner, Evergreen’s existing fleet comprises 206 ships with a total capacity of 1.3 million TEU, making it the seventh-largest ocean liner in the world.
