Singapore’s Kumiai Navigation has returned to Kawasaki Heavy Industries to order a dual-fuel VLGC/ammonia gas carrier newbuilding against a charter from a Canadian energy infrastructure company.

The deal lifts its order tally for the ship type at the Japanese yard to four.

Kumiai managing director Tomomaru Kuroyanagi confirmed the contract, saying the 86,700-cbm ship has been ordered against a minimum seven-year time charter to AltaGas.
