Norway's PGS has lost its final appeal against GC Rieber Shipping in a long-running row over payment for a seismic vessel resale.
PGS went to the supreme court in a last bid to overturn the ruling worth EUR 9m ($10.9m), but failed.
Rieber won a Gulating court appeal in April against PGS.
Its subsidiary Armada Seismic Invest II was sued in 2012 by Arrow Seismic Invest II, now called PGS Geophysical (UK).
