COPENHAGEN, May 6 (Reuters) - Denmark's Tyra natural gas field will only reach peak production in the fourth quarter of this year instead of mid-year due to technical issues with a power transformer, operator TotalEnergies said on Monday.

While the repair work is ongoing, different options to deliver additional gas volumes to Denmark are being explored, TotalEnergies said.

The commissioning of the facilities and gas exports from Tyra continue at present levels, but gas volumes may be redirected to Den Helder, the Netherlands, during remediation, the group added.

The technical issue relates to a transformer delivering power to the intermediate pressure gas compressor.

"We are in close dialog with our supplier of the IP compressor transformer and the whole Tyra team is working diligently to resolve and mitigate the issue as fast as possible," TotalEnergies said.

BlueNord, a partner in the development, has put its production guidance between the second and fourth quarter this year under review as a result of the delay, it said in a separate statement on Monday.

BlueNord expects to give an update on its revised guidance in connection with its first quarter earnings report on Tuesday, it added. (Reporting by Louise Breusch Rasmussen; Editing by Louise Heavens and Mark Potter)
