Intra-Asia liner operator Taiwan’s TS Lines has placed an order for up to four 2,900-teu newbuildings at China’s Fujian Mawei Shipbuilding.

The deal lifts the liner company’s orderbook, including options, to 20 ships worth in total more than $1bn.

The contract is for two firm vessels with an option for two additional ships.

A shipping player close to TS Lines confirmed the order, adding that Fujian Mawei is slated to deliver the firm vessels from the second half of 2023.
