The Tyra field is Denmark’s largest natural gas deposit.

In 2017, the DUC – comprising TotalEnergies, BlueNord and Nordsøfonden – made the decision to rebuild and upgrade the facilities in the field to ensure safe and continuous operations.

In 2019, gas production and deliveries were halted to facilitate the redevelopment of the field, a step needed due to natural subsidence of the reservoir after almost 40 years of continuous extraction. Following the restart of production in March 2024, Tyra II is said to be “one of the most advanced offshore gas facilities in the world”.

The DUC comprises TotalEnergies with a 43.2% stake, BlueNord with 36.8% and the state-owned North Sea Fund (Nordsøfonden) holding 20%.

The consortium is responsible for 86% of Denmark’s oil production and 89% of its gas production. 

BlueNord COO Miriam Lykke said: “I am very pleased that Tyra II has achieved full technical capacity, and we can begin the ramp-up to plateau production before the winter season. The benefits of restarting Tyra II extend beyond increased gas production. With Tyra’s upgraded facilities, we expect a significant reduction in CO₂ intensity and a lower unit operating cost.”

At plateau, the Tyra hub will generate 5.7 million cubic metres per day of gas and 22,000 barrels of condensate from wells and five satellite fields.

The gas from the Tyra hub will be supplied to Europe via two pipelines to Nybro in Denmark and Den Helder in the Netherlands.
