Danish owner Torm is adding four MRs to its fleet in a deal worth $83m.
The company said the unnamed 2011-built tankers will join between August and December this year.
All were constructed at Hyundai Mipo, like 10 other ships in the Torm fleet.
It has "good technical and commercial experience with these vessels," it said.
Potential candidates include a quartet of 52,000-dwt ships built by Mipo that year for Germany's Offen group.
