China’s Jiangsu Ocean Shipping (JOSCO) is expanding its containership fleet with four newbuilds contracted at compatriot yard Jiangsu Soho Chuangke Shipbuilding.

The shipping arm of Jiangsu Port Group has booked a series of 3，000 teu vessels set to become the largest in its fleet.

Jiangsu Ocean lists a fleet of 30 vessels on its website， with the largest boxship at about 1，900 teu.

No price or delivery dates have been divulged for the latest order that follows a deal for a pair of ultramax newbuilds at the same yard， previously known as Sainty Shipbuilding.

The yard in Yangzhou made a comeback to shipbuilding last year after a pause of about seven years with multiple ultramax orders， including Chinese leasing houses and George Procopiou’s dry bulk arm， Sea Traders.
