The strike in oil rig in Norway is expected to aggravate Friday night, cutting total output by around 55,000 barrels of oil a day, the Norwegian Shipowners Association told Dow Jones Newswires Thursday.
The association also said a further 150,000 barrels a day of output is being delayed because the drilling ships aren't able to drill production wells.
The dispute between the association and the Federation of Oil Worker's Union started three months ago, "and there is no end in sight," the association's chief negotiator, Ketil Lenning, said.
So far the strike has cost oil companies, rig owners and oil supply companies, around $119 million, the association said.
