Russia's Sovcomflot (SCF Group) is keeping a Polarcus seismic survey vessel on bareboat charter after winning more work.
The state shipowner had intended to return the 2,250-dwt Vyacheslav Tikhonov (built 2011) to the Middle East company on 15 January.
But Oslo-listed Polarcus said on Tuesday the hand-over was postponed again due to work which its partner was awarded by a third party in Asia.
