OSLO, May 22 (Reuters) - The latest postponement of production at Norway's Hammerfest LNG plant was due to the need for final tests on a compressor that has been repaired, operator Equinor said on Sunday.

"Some final tests are remaining on the compressor," an Equinor spokesperson said.

The plant, which has been offline since a fire in 2020, is now expected to restart on May 27, four days later than the previous plan, Norwegian gas system manager Gassco said earlier. (Reporting by Gwladys Fouche, editing by Terje Solsvik)
