Chinese boxship player SITC International Holdings has exercised options at Huanghai Shipbuilding for two additional 1,800 teu vessels.
The Hong Kong-listed shipowner is paying nearly $58m to lift the series at the compatriot yard to 10, with deliveries for the latest pair scheduled by March and May of 2028.
SITC signed a shipbuilding contract with Huanghai for a series of four firm and six optional 1,800 teu newbuilds in June last year.
According to Alphaliner, the intra-Asia carrier ranks 15th among global container shipping enterprises with a capacity of about 186,000 teu spread across 119 vessels, including 104 self-owned.
