TotalEnergies eyes March 2024 restart date for Denmark’s largest offshore natural gas field
(WO) – TotalEnergies and BlueNord provided an update on progress and expected timeline of the Tyra Redevelopment Project (“Tyra” or “Tyra II”), Denmark’s largest offshore natural gas field.
TotalEnergies confirmed in its REMIT notification on Jan. 22 that the current restart date of March 31, 2024, remains valid. Depending on project progress, it could be reached earlier in March. Further, in the same REMIT notification, TotalEnergies stated that the outcome of tests now suggests that a ramp-up to maximum technical capacity is expected to take four months from restart.
Since BlueNord’s Q3 report, significant work on the completion of the Tyra II facilities has been executed. Leak testing, which is essential to safety and integrity prior to gas-in and the functional testing of key process machinery required for processing, is progressing well.
The Tyra East Riser platform Echo was declared hot, with all pipelines connected. De-isolation of these pipelines has also commenced, which is an important step towards first gas. On Tyra West, the first wells have successfully been unplugged and de-watered, with two wireline teams working in parallel on the Tyra West B and C platforms.
An extensive amount of work has been carried out on the leak testing of the facilities, and it is expected that all leak testing will be completed ahead of first gas export, which could support an efficient and reduced ramp-up period. The key focus before the first gas export remains ensuring the safety and emergency systems are fully functional.
"2024 has started at a high pace, and we have now more than 80% of the preparations for commissioning at Tyra East completed. With tests of all central plants, we are now very close to being able to deliver the first gas," says Michael Lindholm Pihl Larsen, TotalEnergies' technical project manager on the Tyra Reconstruction Project.
More than 1,400 employees offshore and over 230 on land continue to work on final reconstruction activities. Right now, the team is doing the final tests, verifying the new equipment and systems, and fine-tuning certain areas.
Tyra and the surrounding fields Svend, Roar, Harald, Valdemar and Tyra Southeast were decoupled to enable the rebuilding. Work is underway to restore power to the systems, re-establish communications and networks, reopen wells and verify that working conditions are safe. When the re-establishment is completed and the conditions are safe, all fields will gradually be restarted.
About Denmark's Tyra natural gas field. 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 which will deliver gas 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 energy security and independence in Denmark and Europe.
TotalEnergies is the operator of the Tyra field on behalf of DUC – a partnership between TotalEnergies (43.2%), BlueNord (36.8%) and Nordsøfonden (20%).
