Offshore oil workers in Norway are set to end a four month long industrial dispute now that the Norwegian government has intervened to stop it escalating. The association that represents the rig workers’ employers had brought matters to a head by threatening to close down all production, which would have badly hit Norway’s economy.Angry at that the leader of the OFS union, Terje Nustad, had initially said they would stay out until the Norwegian parliament was due to vote to adopt a new law to start the forced arbitration. That would have prolonged the strike until next week. But later the union said its members would go back to work straight away. Norway’s Energy Ministry said the strike has delayed drilling of new production and exploration wells and it would be “a challenge” to achieve the country’s target of raising oil production to three point three million barrels a day next year.
