TotalEnergies restarted production from the Tyra offshore gas installation hub (Tyra II) in the Danish North Sea, 225 km west of the coast of Esbjerg, after completion of a major redevelopment project of the hub, the company said in a release Mar. 22.
In September 2019, gas production was suspended to enable the redevelopment of Tyra. Following decommissioning of the previous Tyra infrastructure, eight new platform topsides, two jackets, and six bridges were installed.
The redeveloped Tyra will decrease field opex and emissions intensity, and at the same time extend its field life by 25 years, only constrained by the 2042 license expiry, partner BlueNord said in a separate release.
Tyra II represents the central hub for Danish natural gas production in the North Sea. It processes gas from Tyra field and from surrounding satellites and Dan field. Gas from the Tyra hub is delivered to Europe through two export pipelines to Nybro in Denmark and Den Helder in the Netherlands.
Earlier in March, TotalEnergies entered the final stages of the project as gas from Dan F platform entered the system. Gas from Dan field was the first to be reestablished to the hub, and gas flow was expected to be gradually reestablished from Harald, Svend, Roar, and Valdemar, as well as wells from Tyra field (Southeast, West, and East).
At plateau, Tyra hub will produce 5.7 million cu m/d of gas and 22,000 b/d of condensate. Gross reserves at Tyra are more than 200 MMboe.
TotalEnergies operates Tyra field on behalf of Danish Underground Consortium, a partnership between TotalEnergies (43.2%), BlueNord (36.8%) and Nordsøfonden (20%).
