Kumiai Navigation has added a dual-fuel VLGC newbuilding at Kawasaki Heavy Industries — doubling the number of 86,700-cbm LPG/liquefied ammonia gas vessels it has on order there.

Managing director Tomomaru Kuroyanagi confirmed the order, saying Kumiai has declared an option attached to a single-ship order signed there last year.

“We have a total of two dual-fuelled VLGC newbuildings that can load ammonia,” he said.
