Oldendorff Carriers has added up to nine newbuildings to its orderbook as it continues to expand its owned fleet.

Market sources said the German bulker operator has returned to China’s Jiangsu Hantong Heavy ­I­ndustry to order at least two kamsarmaxes. The deal involves two firm 82,000-dwt vessels, although one shipbuilding source said it includes two options.

This source said that including the latest firm newbuildings, Olden­dorff has seven kamsarmaxes under construction at Hantong.
