Norwegian energy companies have struck a wage deal with offshore oil workers, averting a strike that threatened production in three oil and gas platforms in the North Sea.

Around 400 workers on the Gullfaks B and Gullfaks C fields, operated by Statoil, and Shell’s Draugen field planned to strike if no agreement was reached with management about pay.

Three trade unions – Industri Energi, SAFE and Lederne – negotiated with the companies to reach an agreement.

The Norwegian Oil Industry Association (OLF), representing the companies, said the wage deal includes a $1,573 annual increase in general wages for 6,700 workers as well as NKr4,700 ($740) from a previous pay deal.

The Gullfaks and Draugen fields together produce about 270,000 barrels of oil per day out of Norway’s daily exports of about two million barrels.
