Milestone: The Tyra hub is now reconnected to the surrounding fields
Esbjerg, 7 September 2023 – The Tyra Redevelopment project has now marked yet another important milestone on the path to resume production: The project team has completed the final work on the subsea infrastructure which connects Tyra with the surrounding fields. Together, the fields will contribute to Denmark's and Europe’s energy security and independence once Tyra’s production is back at full capacity.
During the redevelopment, Tyra and the surrounding fields were temporarily disconnected and the satellite platforms Svend, Roar, Harald, Valdemar and Tyra South East were put into idle mode to enable the removal of the old Tyra and installation of the new Tyra.
Before the summer break, Tyra was reconnected to Denmark following the successful installation of the final connecting riser piece on the gas export pipeline to shore. Now, we have closed the full circuit of critical infrastructure around the Tyra field. With the milestone achieved, we are ready to power-up and operate the surrounding unmanned satellite fields once again which is a crucial step towards first gas,
says Michael Lindholm Pihl Larsen, Technical Project Lead of the Tyra Redevelopment Project at TotalEnergies EP Denmark A/S.
The gas coming from the surrounding fields will be treated at the high-tech processing platform at Tyra East. Here, the final dehydrated and cooled product will be created and exported with the help of compressors.
At the new Tyra, we have seven gas compressors which are all made with the newest technology, and they are all electrically driven ensuring lower CO2 emissions. The compressors are highly important for the start-up of Tyra as they process and supply the gas from Tyra and the surrounding fields to shore. Currently, the team works diligently to test one compressor after the other. During the past month, we managed to successfully test the crucial export compressor which will distribute first gas to Denmark this winter,
explains Michael Lindholm Pihl Larsen.
With the reconnection of the Tyra hub and test of the export gas compressor achieved, the largest infrastructure project in the Danish North Sea is now in the final phase where all hands are on deck, performing thorough tests of the equipment to verify the integrity of the systems, guarantee high quality, and ensure safe work conditions for the crew before gas will enter the new facilities and re-start Tyra’s production in the winter season 2023/24.
Facts on the Tyra Redevelopment
- TotalEnergies is the operator of the Tyra field on behalf of DUC – a partnership between TotalEnergies (43.2%), BlueNord (36.8%) and Nordsøfonden (20%).
- Tyra is Denmark’s largest natural gas field and has been a center for processing and exporting more than 90% of the natural gas produced in the Danish North Sea before its redevelopment. This was necessary due to the field’s natural subsidence of the chalk reservoir after many years of production.
- The redevelopment of the Tyra field includes three main elements: decommissioning and recycling of the old Tyra platforms; recycling and extending the current platform legs on six of the platforms with 13 meters, which will have new topsides; a completely new process module and a new accommodation platform.
- Once the modernized Tyra II is back on stream, it will be the most modern natural gas field in the world and is expected to deliver 2.8 billion cubic meter gas per year to Denmark and Europe through the export pipelines to Nybro and Den Helder.
- Tyra II will secure continued production of natural gas with 30% less CO2 emissions and contribute to gas consumption in Denmark and Europe.
- More than 1,500 people offshore and over 250 people on land are currently working on the final redevelopment activities such as reinstating the compressors and testing equipment.
