Sajjan Jindal-led JSW Infrastructure is to go ahead with new mini-bulker orders totalling 14 vessels.
The Indian company, part of Jindal Group, already has 18 8,000-dwt ships contracted at yards in India, Bangladesh and China as it seeks to build a fleet of 32 ships.
The river-sea ships are intended to move cargo between its own Jaigarh and Dharamtar ports for its steel mill and a new cement plant at Dolvi.
