Irish owner Arklow Shipping has inked deals for four more bulkers at Ferus Smit.
The 16,500-dwt vessels will be delivered in September and December 2018, plus May and November 2019, Clarksons said.
No price was given for the ships.
The yard is already building nine 5,100-dwt bulkers for Arklow for delivery up to 2018, having handed over one already.
Arklow has an operational fleet of 47 ships.
