Borealis Maritime is the buyer of two anchor-handling tug supply ships sold off by K Line Offshore as it exits the sector.
The UK shipowner's Norwegian offshore vessel arm, Aurora Offshore, said that it will operate the 34,000-bhp KL Sandefjord and KL Saltfjord (both built 2011) after the parent acquired them in December.
K Line Offshore, controlled by giant Japanese owner K Line, is being liquidated in Norway following years of losses.
