Last connecting bridge touched down: Tyra II now has its final shape
Esbjerg, 10 October 2022 – The last remaining piece of Tyra II puzzle was lifted into its final position. The world’s largest crane Sleipnir will soon leave the Tyra field after a successful installation campaign.
Yesterday at 17:04, the 85.4-meters long bridge was set down between the new Tyra II processing platform and the accommodation platform. Now all dots of Tyra II are connected and lifting the final four Tyra II pieces – the process module, two bridges and a flare tower – comes to a successful end.
In the coming days, the installation team will finish the last welding work to ensure that the new modules can resist many years of rough North Sea weather. Afterwards, the team will hand over the baton to the hook up and commissioning team who will focus on completing and powering up the installed platforms and reconnecting them to the existing North Sea infrastructure. That will be the last phase before delivering the first gas from Tyra II in the winter season 2023/24.
It’s exciting to be able to see the complete shape of Tyra II as all eight platforms, six bridges, two jackets and one flare are now in their final position. I’m very proud of our installation team and our skilled partner Heerema Marine Contractors who once again executed textbook lifting operations. Nevertheless, there is still a lot of work offshore to complete in order to get Tyra II ready for first gas in the winter season 2023/24
says Lars Bo Christiansen, Deputy Project Director for TotalEnergies EP Denmark A/S.
Facts about the final installation
- More than 260 people execute the lifting of the process module, two bridges and one flare onboard Sleipnir in October 2022.
- On 4 October 2022 at 8:27 AM, the biggest and final Tyra II topside was safely installed at the Tyra field. The lift of the 17,000 tons heavy process module broke a world record as the heaviest crane lift ever undertaken at sea.
- The final Tyra II module lifted into position was the bridge connecting the accommodation- and process platforms. It is 85,4 meters long and weighs 370 tons.
- Sleipnir is the world’s largest crane vessel from TotalEnergies’ EPC contractor Heerema Marine Contractors. Sleipnir’s two huge cranes can lift a weight of up to 20,000 tons. The vessel is 220 meters long and 102 meters wide – a size equivalent to approximately 3 football fields.
- Sleipnir has been part of the Tyra removal campaign and helped install the new jackets in September 2020 as well as the remaining new Tyra II modules including the accommodation module, six well head and riser modules, and 4 bridges in September 2021 and April 2022.
Facts on the Tyra Redevelopment
- TotalEnergies is the operator of the Tyra field on behalf of Danish Underground Consortium (DUC) – a partnership between TotalEnergies (43.2%), Noreco (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.
- A redevelopment of the Tyra field is 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; 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 is expected to deliver 2.8 billion cubic meter gas per year which amounts to 80% of the forecasted Danish gas production.
- Tyra II will secure continued production of natural gas with 30% less CO2 emissions and contributing to energy security of Denmark’s and Europe.
