Tyra, a major offshore project at the core of our climate strategy

Country: Denmark 
Production type: Natural gas 
Operator: Danish Underground Consortium (DUC) 
Partners: TotalEnergies (43.2%), Noreco (36.8%), Nordsøfonden (20%) 
Start-up date: 

reduction of C02 emissions targeted with the redevelopment of the Tyra field

The Tyra platform has been a major part of the North Sea’s energy infrastructure for nearly 40 years. Located off the coast of Denmark, the facilities at the Tyra field are key infrastructure as more than 90% of the country’s natural gas are processed and send to shore via the Tyra facilities. 
Its redevelopment, which has become necessary due to natural subsidence of the reservoir, is an opportunity to secure and revitalize production. The advanced technologies used will enable reduction of the environmental footprint of the new Tyra and optimize the energy efficiency of its operations.

A strategic project for the danish gas market

Since 1984, when production started on the platform, the Tyra gas field has supplied the majority of the gas produced in the country. 
Fully committed to the long-term development in the Danish offshore sector, Our Company has decided to invest in rebuilding the platform. Continuous gas extraction over nearly 40 years has led to natural subsidence of the infrastructure.  
Tyra’s redevelopment meets a dual objective: to build a state-of-the-art facility offering heightened safety for its teams, and to revitalize its production and export capacity, which should ensure gas provision for the Danish population for the decades to come.  
Significant output is expected: once redeveloped, at peak production, the completion of the Tyra project will enable supply of around 60,000 barrels of oil equivalent per day, i.e. total production of 200 million barrels over the next 25 years.  
Thus, Tyra’s redevelopment offers new opportunities and becomes a necessary as well as strategic project.

A major forward looking transformation

The modernized, revitalized Tyra platform will be more productive, but also more virtuous environmentally. Its transformation requires a large-scale technical and logistical mobilization.  
The teams involved in the project began by decommissioning the old, obsolete facilities. This removal stage was completed during the summer of 2020 and required two of the world’s largest construction and crane vessels. In total, 50,000 metric tons of material were removed, which is the equivalent to seven Eiffel Towers. 
The next steps in the transformation will be to recycle the old modules, complete the construction of the new modules and install them at the Tyra field. The objective is to modernize the site to increase its operational efficiency from 80% to 90%. 
When the works are completed, Tyra will be a superb facility, equipped with new technologies and methodologies such as: 

  • sensors that constantly collect data about the status of the infrastructure and equipment at more than 100,000 key points on the platform;
  • digital tools that measure performance and improve maintenance;
  • portable digital tools that give teams constant access to systems, data, drawings, etc., along with specialized onshore support;
  • applications designed for operators to share available data with onshore and offshore teams to improve the synergy of ideas and analysis. 

Tyra’s transformation will also have a significant impact on its energy efficiency: CO2 emissions will be reduced by 30% and flaring can be reduced by 90%. 
Reducing the environmental footprint of Tyra’s operations forms part of TotalEnergies’ climate strategy. With this large-scale project, and as a responsible, broad energy company, we intend to play its part in supporting the European transition to the low-carbon energies of the future.
