As a result, production from the field is likely to cease in October 2018. Under EU regulatory requirements, a decision impacting production must be notified to the market in a timely manner.
Tyra is Denmark’s largest offshore gas field and the facilities serve as the processing and export center for all gas produced by theDanish Underground Consortium (DUC), operated by Maersk Oil in partnership with Shell Nordsøfonden and Chevron, and more than 90% of Denmark’s total gas production.
Tyra East and Tyra West is also the hub for various smaller facilities on the Tyra field, including the unmanned Tyra Southeast complex, which was extended in 2015.
Maersk Oil COO Martin Rune Pedersen said: “The Tyra facilities are approaching the end of their operational life, and together with our partners in DUC we have assessed solutions for safe decommissioning and possible rebuilding of the…facilities.”
Over the past 15 years, the Maersk-led DUC has spent more than DKK1 billion ($141 million) on reinforcing the Tyra offshore structures.
However, they cannot safely continue producing in light of new findings on storm wave impact, combined with subsidence of the underground chalk reservoir which reduces the gap between the platforms and the sea.
“In January 2017 we will have to reallocate resources from Tyra rebuild planning to engineering work for a detailed plan to discontinue the Tyra field as the Danish hub for gas processing,” Pedersen added.
However, Maersk will maintain dialogue with the Danish authorities to identify terms for securing future investments in the Danish North Sea, including rebuilding of Tyra.
