Taiwanese carrier TS Lines is adding more tonnage to its fleet, signing up for 2,900 teu containerships at China’s Fujian Mawei Shipyard in a deal worth $168.6m.

The Hong Kong-listed intra-Asia operator has contracted four firm vessels, with deliveries slated by May 2029, further building out its feeder fleet.

The latest order follows a pair of similar newbuildings contracted in November 2025 for delivery between mid- and late-2028, also at Fujian Mawei, taking the company’s total 2,900 teu series at the yard to six.

The move extends a relationship between TS Lines and the Chinese builder that dates back to 2021, when the carrier launched a major newbuilding programme. That earlier series included eight 1,100 teu ships and six 2,900 teu vessels — at the time the largest containership project undertaken by the yard — with all units delivered by early 2024.

TS Lines, ranked 20th globally, operates a fleet of about 40 ships, largely focused on intra-Asia trades. The company has been steadily renewing and expanding its fleet to stay competitive in the regional feeder segment.

The Mawei orders come on top of a separate series of larger ships booked last year at Huangpu Wenchong Shipbuilding, where TS Lines is building 5,000–5,300 teu vessels for delivery across 2028 and 2029.
