Great engineering
The Tyra field has been at the heart of Denmark’s energy infrastructure for more than 35 years. Before the temporary shut-in in 2019, the Tyra field was responsible for processing and further distributing more than 90% of the natural gas produced in the Danish North Sea, to both Danish consumers as well as several European neighbors. TotalEnergies is the operator of the Tyra field on behalf of DUC – a partnership between TotalEnergies (43.2%), BlueNord (36.8%) and Nordsøfonden (20%). The DUC partners invest approximately DKK 27 billion in redeveloping the Tyra field. On 21 March 2024, production from the redeveloped Tyra was safely resumed – a monumental milestone on the way to full capacity.

Tyra II is a high-tech natural gas hub consisting of eight platforms – The accommodation platform rises 43 meters above the water’s surface and has 7 floors with a helideck at the top.

Size can be difficult to relate to. But by comparison, the accommodation platform alone is on a par with the Round Tower in Copenhagen and weighs the same as just under 15 jumbo jets.

With the development of Tyra II, our engineers have succeeded in reducing CO2 emissions from the new field by 30 percent compared to the former facilities. This is possible thanks to new technology, better monitoring, and use of big data that all together will ensure a much more efficient production. In addition, Tyra II is made of materials that require only limited maintenance.

Tyra has also been allowed to keep most of her jackets. Instead of producing and establishing new ones at the bottom of the North Sea, we were able to save resources and emissions by reusing the old jackets to carry the new production platforms, which have been extended by 13 meters. Tyra II will then stay high above sea level for many years to come.

Tyra II is equipped with more than 100,000 sensors. Not only to make production efficient and operations easier. It will also increase the safety of our crew. When you have a workplace 225 km from shore out in the North Sea, safety is always the priority – our core value.

A home away from home
Tyra II has a brand-new accommodation platform for the many employees whose day-to-day work is 225 km out in the waves and wind of the North Sea.

It is essential that they feel comfortable, and we have done our best to build the closest we can get to a home away from home.

We have upgraded the employees’ accommodation so that it is furnished with high-quality Danish furniture, lamps, carpets and designs that are as close as possible to what they know from life on land.

In addition, the new platform has an outdoor recreational area, restaurant, cinema, fitness, and a well-equipped common area.

Safety, efficient workflows, and overall well-being have been important focus areas in the design. In this context, the accommodation platform must also be as a workplace, which includes a control room, administration, preparedness, evacuation, and helicopter traffic.

The entire platform is created with open spaces, a smart layout, noise reduction and the possibility for socializing.

We are building Tyra II together with the local forces
Throughout the project to remove the old Tyra and to build Tyra II, it has been a high priority to use the highly qualified expertise that exists in Esbjerg and Southern Denmark. Overall, we get help from some of the world’s most skilled specialists in the field, and more than 85 local companies in the offshore sector around Esbjerg are actively contributing to the entire removal of the old Tyra and construction of Tyra II.

Among other things, a big focus has been put on recycling and reusing 98.5% of the old Tyra. As such, local companies disassembled old parts, renovated them, installed new technology and reassembled it, giving them a new life on Tyra II.

The largest share of local jobs and activities involved the hook-up and commissioning of Tyra II. In total, more than 3 million workhours have been spent offshore.

And that’s only one part of the big project. In addition, the uninstallation and dismantling of the old Tyra platform was done by hundreds of professionals and experts in collaboration with a large number of local companies.

Tyra II was created with the help of the whole world
The original Tyra’s two main platforms – the accommodation and processing modules were sailed to Frederikshavn and separated.

The new accommodation platform for Tyra II was constructed in Italy, the production platforms were built in Singapore and the new processing platform took shape in Indonesia.

Tyra II is a global project anchored in Esbjerg. Many parts of the project are represented by many different nationalities, which requires an impressive overview and a well-defined structure.
