Denmark’s largest gas field, Tyra, has reached full operation and the major redevelopment project is officially completed, according to an announcement from energy company in Denmark TotalEnergies on behalf of the Danish Underground Consortium. Now Denmark will once again be both self-sufficient and a net exporter of gas, supporting Danish and European energy security.
“It’s crucial for us that Tyra has now achieved full operation. We have been working to achieve this since 2019, when production was temporarily shut-in to enable the redevelopment. Production ensures Denmark a stable gas supply as we develop a greener energy system,” said Ole Hansen, managing director at TotalEnergies EP Denmark.
Hansen added: “The Tyra gas hub is expected to supply up to 2.8 billion cubic meters of gas per year, which is comparable to Denmark’s annual gas consumption of 1.4 billion cubic meters in 2024. Therefore, the production also contributes to the energy security of our European neighbors.”
Tyra has been a key part of Denmark’s gas supply since 1984.
Due to the subsidence of the seabed beneath Tyra, it was decided in 2017 to rebuild the facilities to secure production for decades to come.
Thousands of TotalEnergies employees and experts at suppliers have been dedicated to removing, reusing and recycling the old Tyra and building new facilities.
Since restarting production in March 2024, TotalEnergies said it has focused on increasing production and restoring gas flow from the surrounding fields.
Ole Hansen noted that Tyra will play an important role in Denmark’s energy landscape for decades to come supplying Danish gas from the North Sea at 30% lower CO2 emissions compared to the former facilities.
“The highly complex redevelopment is an illustration of the world-class offshore capabilities of the North Sea offshore industry based in Esbjerg. A task that would not have been possible without the thousands of skilled and dedicated people from several global and local companies, who have spent more than 46 million man-hours getting us to where we are today,” added Hansen.
Tyra is located 225 kilometers off the west coast of Denmark in the North Sea.
Tyra can be remotely controlled from shore and can produce gas at lower emissions.
This is possible, TotalEnergies said, due to the simplified infrastructure, 100,000 data points collected through sensors, new processes, lower production levels and improved energy efficiency.
Tyra can produce and export gas from several fields, including Tyra East, Tyra West, Tyra Southeast, Harald, Valdemar and Roar.
The gas is delivered to Europe through export pipelines to Nybro in Denmark and Den Helder in the Netherlands.
TotalEnergies operates the Danish Underground Consortium with a 43.2% share together with partners BlueNord (36.8%) and Nordsøfonden (20%).
TotalEnergies is an energy company in Denmark, with operations in oil and gas as well as renewable electricity, employing a diverse and international workforce of around 1,200 people located in Esbjerg, offshore, and in Copenhagen.
