Polish Steamship Co (Polsteam) has doubled its tally of newbuildings at Yangfan Group.
The European bulker giant has added four more open-hatch handysizes at the Chinese facility, lifting the total to eight, and a yard official confirms the deal.
The Szczecin-based owner will take delivery of the latest ships in the second half of 2016.
Polsteam signed up for its earlier quartet in August for delivery in early 2016.
