Japan’s Mitsui & Co has added another kamsarmax newbuilding to its growing bulker fleet.

Shipbuilding sources said the Japanese trading house has booked the 82,000-dwt ship at Yangzijiang Shipbuilding, bringing the total number of such vessels it has on order there to nine.

The contract is believed to have been signed last month.

Yangzijiang declined to comment on the order, citing contract confidentiality.
