The Tyra platforms have been at the core of Denmark’s energy infrastructure for 30 years, processing 90% of the nation’s natural gas production. As the responsible energy major, Total is investing more than 300 million dollars to redevelop the Tyra platforms in the Danish North Sea to support Denmark and Europe’s transition towards a low-carbon energy future.
Opening doors to new opportunities
The redeveloped Tyra will be a high-tech production and export center that will secure gas supply for many years ahead. At peak production, the redeveloped Tyra will provide enough gas to supply the equivalent of 1.5 million Danish homes.
Following completion in 2022, the new Tyra platform is expected to deliver approximately 60,000 barrels of oil equivalent (boe) per day, equating to over 200 million boe over the next 25 years.
Total is committed to the long-term development of the Danish offshore sector. The Tyra redevelopment project will not only promote economic and social benefits, but it will become a catalyst for other development opportunities in the North Sea.
One of the aims of Tyra's redevelopment project is to pave the way for new investments from the Danish Underground Consortium (DUC) partners and third-party tiebacks.
Moreover, Total hopes to add reserves by assessing known areas near Tyra and exploring new opportunities nearby.

Rebuilding and revitalizing Tyra
The original Tyra platform started production in 1984 and has since been complimented by several satellite platforms. However, due to subsidence, redevelopment is necessary. Subsidence is a natural consequence of continuously extracting oil and gas from gas fields over decades.
That extraction causes the hydrocarbon pockets in those gas fields to collapse and the seabed to sink. The seabed below the Tyra platforms has sunk nearly five meters since 1984.
As a result, the gap between the sea and the Tyra platforms’ decks was reduced. This reduction ultimately means redevelopment is necessary to keep both crew and equipment safe, as well as keep production efficient.
The execution of Tyra's redevelopment project is both a global and local effort. In addition to fabricating installations in both Europe and Asia, project efforts are being executed locally in Esbjerg, and offshore in the Danish North Sea.
The redevelopment project started in 2018, with the first steel cut on the new platforms. Following a safe and well-executed offshore campaign, the Tyra field’s production was temporarily suspended in September 2019 to allow the next steps in the redevelopment project to take place.
The unique scope of work for Tyra's redevelopment project includes removing old facilities, modifying existing ones, and installing new features.
The two existing process and accommodation platforms will be replaced by one new process platform and one new accommodation platform. The four wellhead platforms and two riser platforms will have their jackets extended by 13 meters, and the current topsides will be replaced.
A high-tech field for the future
The new Tyra will be a state-of-the-art facility ensuring efficient production and enhanced safety. With the use of new technology and modernized working processes, Total anticipates that Tyra’s operational efficiency will increase from its current average of around 80% to more than 90% after launching.
These new technologies and methodologies will be integrated with the redeveloped Tyra platforms:
- Sensors that continuously collect data about critical equipment from around 100,000 data points.
- Digital and online tools to monitor performance and improve maintenance.
- Handheld digital devices for offshore employees to have constant access to systems, data, drawings, etc., as well as onshore specialist support.
- Big data and shared data availability for both onshore and offshore staff to foster better collaboration, understanding and analytics.
Utilizing such efficient infrastructure and modern technology, the Tyra Redevelopment Project also supports Total’s vision of making our operations more sustainable.
A cornerstone in Total's climate strategy
The vision for Total’s climate strategy is to mitigate climate change issues while meeting energy demands. Tyra's redevelopment project is an important part of realizing that vision.
The platform is designed to minimize the environmental footprint of our Danish operations. In fact, Total expects that the redeveloped Tyra will reduce 30% of CO2 emissions, 90% of flaring, and improve overall operational energy efficiency.
At the same time, redeveloping Tyra is also important because natural gas is a cornerstone of Total’s climate strategy. Total intends to make natural gas a bigger part (60% within 20 years) of our oil and gas mix.
