OSLO (Reuters) - Ongoing strike action in Norway has led to the delay of scheduled maintenance at Norway's biggest producing gas field and a major processing plant, North Sea gas infrastructure operator Gassco said on Monday.

Almost 25,000 private-sector workers in Norway went on strike earlier on Monday after talks between two major trade unions and employers broke down on Sunday.

The strike action means that annual maintenance due to take place at the Troll A platform in the North Sea between April 18 April 22, curtailing exports by some 35 million cubic metres per day (mcm/day), has been cancelled.

"Maintenance cancelled due to ongoing strike," Gassco said in a market message.

Kollsnes, the plant onshore that processes the gas from Troll, is cutting short an ongoing maintenance. It started on Sunday and was due to end on April 26, curtailing output by some 39 mcm/day. It will instead end on Tuesday.

Gassco was not immediately available for further comment.
