Chinese bulker company Jiangsu Ocean Shipping (Josco) is renewing its bulker fleet with orders for four ultramax newbuildings.

The Nanjing-based shipping company has contracted compatriot shipyards Dalian Cosco KHI Ship Engineering (Dacks) and Nantong Cosco KHI Ship Engineering (Nacks) to construct two 61,000-dwt bulker newbuildings each.

A shipping source familiar with Josco said the ultramax newbuildings are part of the company’s fleet renewal programme.
