OSLO- Around 200 Norwegian offshore oil and gas workers plan to go on strike on June 4 unless wage negotiations lead to a deal with employers, the Lederne labour union said on Wednesday.
A strike would hit seven offshore fields and could thus result in lower output from Western Europe's largest producer of crude oil and natural gas.
Equinor's EQNR.OL Kristin, Oseberg East and Gudrun platforms would be affected, as would Neptune Energy's Gjoea, Okea's Draugen and Aker BP's AKERBP.OL Ivar Aasen, the union said.
ConocoPhillips-operated Ekofisk installations were also on the list, it added.
Also known as the Norwegian Organisation of Managers and Executives, the Lederne union could later escalate a strike to comprise around 1,000 workers.
Under Norway's rules for collective bargaining, a state-appointed mediator has set a mandatory June 3 deadline for the talks, and a strike is only allowed from the following day.
