TotalEnergies confirmed in its January 22 REMIT notice that its current resumption date of March 31, 2024 remains in effect. Depending on the progress of the project, this could be achieved in early March. Additionally, in the same REMIT notice, TotalEnergies stated that test results suggest that ramping up to full technical capacity is expected to take four months from restart. I did.
Since BlueNord’s third quarter report, significant work has been carried out towards completion of the Tyra II facility. Leak testing, essential for safety and integrity prior to gas injection, and functional testing of key process machinery required for processing are progressing well.
Tyra East Riser platform Echo has been declared hot with all pipelines connected. De-sequestration of these pipelines has also begun, an important step towards first gas. At Tyra West, two wireline teams working in parallel on the Tyra West B and C platforms successfully unplugged and drained the first well.
Extensive work has been carried out on leak testing the facility and it is expected that all leak testing will be completed prior to the first gas export, potentially supporting an efficient and shortened start-up period. there is. A key focus before the first gas export remains to ensure that safety and emergency systems are fully functional.
“2024 has started at a high pace, with over 80% of commissioning preparations at Tyra East now complete. All central plant testing has been completed and we are very close to being able to deliver first gas. ,” he said. Michael Lindholm Pihl Larsen, TotalEnergies’ Technical Project Manager for the Tyra Reconstruction Project.
More than 1,400 offshore and 230 onshore employees are working on final recovery efforts. The team is currently undergoing final testing, validating new equipment and systems, and fine-tuning certain areas.
To allow for reconstruction, Thira and the surrounding fields of Sven, Roa, Harald, Valdemar and southeastern Thira were cut off. Work is underway to restore power to the system, re-establish communications and networks, restart the well, and ensure working conditions are safe. All fields will be reopened in stages once restoration is complete and conditions are safe.
About the Tyra natural gas field in Denmark. Tyra is Denmark’s largest natural gas field and, prior to its redevelopment, was the processing and export center for more than 90% of Denmark’s natural gas produced in the North Sea. This was necessary because the field’s chalk reservoir had naturally subsided after years of production.
The redevelopment of Tyra Field includes three main elements. One is decommissioning and recycling the old Tyra platform. Six of the 13-metre platforms will reuse and extend the current platform legs and have new tops. A completely new process module and a new adaptation platform.
When the modernized Tyra II returns to operation, it will become the world’s most modern natural gas field, supplying gas to Denmark and Europe through export pipelines to Nybro and Den Helder.
Tyra II will reduce CO2 emissions by 30% and ensure continuous production of natural gas, contributing to Denmark and Europe’s energy security and independence.
TotalEnergies is the operator of the Tyra field on behalf of DUC, a partnership between TotalEnergies (43.2%), BlueNord (36.8%) and Nordsøfonden (20%).
