Tyra redevelopment progresses with successful process module lift
Work on the North Sea Tyra redevelopment project has advanced with the successful offshore lift and installation of the Tyra II process module (TEG), partner Norwegian Energy Co. ASA (Noreco) and Heerema Marine Contractors said in separate releases Oct. 4.
The 17,000 metric tons process module was lifted onto waiting jackets and installed by Heerema' Sleipnir. The lift broke a world record as the heaviest crane lift ever undertaken at sea.
All eight platforms are now in their final position at Tyra field. Over the coming weeks, Sleipnir will lift and install two bridges and the flare for Tyra II, completing the project's final offshore lifting and installation campaign. When all connections are welded, TotalEnergies’ hook-up and commissioning team will focus on completing and powering up the installed platforms and reconnecting them to the existing North Sea infrastructure.
With installation of the TEG, “the risk profile changes significantly,” said Marianne Eide, chief operating officer at Noreco. “With remaining execution taking place solely at the Tyra field we are today several steps closer to a near doubling of production from the DUC [Danish Underground Consortium] with Tyra onstream next winter," Eide continued.
The consortium, in August, noted the project’s delay to winter 2023-2024 from second-quarter 2023 driven by global supply chain challenges that impacted fabrication work on the process module (OGJ Online, Aug. 3, 2022).
Tyra is the largest gas condensate field in the Danish Sector of the North Sea. Its facilities process more than 90% of gas produced in Denmark, as well as the entire gas production of the Danish Underground Consortium (DUC) comprised of operator TotalEnergies SE 43.2%; Noreco 36.8%, and Nordsøfonden 20%.
