China’s Nanjing Tanker is continuing its fleet renewal with a series of panamax tanker newbuilds at a domestic yard.

The Shanghai-listed owner under the China Merchants Group said in a filing it would order four 65，000 dwt carriers at Guangzhou Shipyard International (GSI) for about $250m.

The vessels are designed to be methanol dual-fuel ready and should deliver in succession from 2027 to 2028.

In September， Nanjing Tanker also revealed its subsidiary in Singapore would head to GSI for a quartet of MR product carriers worth $182.8m and delivery set for 2027， while another subsidiary Nanjing Yangyang Chemical Shipping would build an 18，000 dwt vessel at affiliated China Merchants Jinling Shipyard for about $34.5m.

The company founded in 1993 says it currently controls a fleet of more than 70 ships.
