Norwegian offshore oil workers threatened to go on strike if annual pay talks with employers fail.
324 workers plan to go on strike starting September 30, according to trade unions Safe, Industri Energi and Lederne.
From Equinor’s Johan Sverdrup field, 88 workers from Safe and 43 from Lederne would go on strike, including some control-room operators. Along with them are 25 workers from the Ekofisk Lima platform of ConocoPhillips, 168 of Industri Energi, and 39 service workers employed by ESS at Aker BP's Ula and ConocoPhillips's Eldfisk Bravo.
During preliminary bargaining on September 7 and 8, Norwegian oil companies and union failed to reach agreement. They will be subject to mandatory state-led mediation on Monday and Tuesday in a bid to prevent a strike.
The oil firms are represented by the Norwegian Oil and Gas Association (NOG) and the unions are negotiating on behalf of a combined 7,300 workers.
If the deal is failed to be reached, the dispute could subsequently be escalated, and union members will be eligible to go on strike.
The NOG did not immediately respond to a request for comment and the unions have not publicly released details of their demands.
