TotalEnergies resumes gas flow from first field as North Sea project enters ‘core’ start-up phase

TotalEnergies EP Danmark, a subsidiary of France’s energy giant TotalEnergies, is days away from bringing its redevelopment project in the Danish sector of the North Sea back online, as gas from one of the fields begins to flow into the offshore facilities.

Shortly after TotalEnergies confirmed the beginning of the methanol loading activities at Tyra II, the French giant disclosed in a remit notification, issued on behalf of its partners in the Danish Underground Consortium (DUC), that the gas flow from the Dan field was re-established into the Tyra facilities. The DUC is a partnership between TotalEnergies (operator, 43.2%), BlueNord (36.8%), and Nordsøfonden (20%).

“We are now entering the core of the start-up: while we flow the gas through the facilities, all last verifications are being performed before gas processing and export to shore can resume,” highlighted the French energy giant.

While the flow of gas from the Dan F platform is the first to be restarted to the Tyra hub, the natural gas flow from the satellite fields and reservoirs will also be gradually returned online. The anticipated start-up date of Tyra II remains in March, with the arrival of gas from the project to Denmark expected between March 21 – 31, 2024.

According to TotalEnergies, Tyra II represents the central hub for Danish natural gas production in the North Sea, processing gas from the Tyra field, which is said to be Denmark’s largest natural gas field, and the surrounding HaraldSvendRoar, and Valdemar satellites along with the Dan field. 

At the processing module called TEG, the gas goes through different steps to reach the required pressure to enable the gas flow to the Danish market. After it reaches full capacity, Tyra II is expected to deliver 2.8 billion cubic meters of gas per year, which amounts to 80% of the forecasted Danish gas production.

Potential gas from a well in the Harald East area, for which a final investment decision (FID) was recently taken, is set to be exported through the Tyra East facilities, if the upcoming drilling operations yield hydrocarbons.
