Greece's Diavlos Salvage and Towage has abandoned an anchor handling tug-supply vessel (AHTS) in Norway after crew went unpaid for six months, said unions and port-state authorities.

Officials of the Norwegian Maritime Authority (NMA) said all crew members on the 12,240-bhp Diavlos Force (built 1983) have been repatriated. Now, the ship appears abandoned after an insurance payout covering the unpaid wages.
