The Arkas Group, Turkey’s biggest container ship owner, has returned to China for newbuildings that will boost its fleet beyond the 50-vessel mark.

The four 4,300-teu boxships contracted at CSSC’s Guangzhou Wenchong Shipyard are set to be the biggest ever to join the company’s fleet.

They will cost $240m in what is Izmir-based Arkas’ first newbuilding order in eight years.
