- Today, the Tyra field consists of two main centres: Tyra East and Tyra West. Tied into the centre are 5 unmanned satellites: Tyra Southeast, Harald, Valdemar, Svend and Roar
- The unmanned satellite platforms in the area have not been affected by subsidence, and will therefore not be redeveloped. Production from the satellites will be temporarily shut down during the redevelopment
- Production from Tyra is expected to be shut-in temporarily in December 2019 to enable the removal, renovation and re-development of the facilities
- Once its redevelopment has been completed in 2022, Tyra will again play an important role in the reliable and secure supply of gas to Denmark
- The redevelopment of Tyra is dependent on the Danish Parliament passing the bill on the agreement made (expected in October 2017) and on Maersk Oil taking a final investment decision on the project, which is expected by December 2017
How do you solve a problem like an offshore platform sinking into the seabed?
The short answer is that it takes a lot of planning and expertise, and a strong partnership between operator, DUC partners, government, suppliers and research institutions. But that only begins to tell the tale.
“The current gap between the platform and sea level is about 15 metres, and with wave heights reaching 10-15 metres during severe winter storms this naturally poses a safety risk, which Maersk Oil as a prudent operator needs to mitigate,” explains Morten Hesselager Pedersen, who is the Head of Tyra Future Development.
Oil and gas have been produced in the Danish North Sea for half a century. There is still a lot more that could be extracted, but the right investment and expertise are needed to do so.
Maersk Oil is the largest oil operator in Denmark and its biggest partnership is the DUC, where 85% of the country’s oil and 97% of its gas exports stem from. They have reached an agreement with the Danish government that provides terms that will enable the partners to proceed with a full re-development of the Tyra facilities. This in turn will pave the way for future oil and gas investments in the Danish North Sea and protect jobs within the industry.
The re-development will restore the functionality of the current facilities, including the gas processing hub and five surrounding satellite fields, and therefore ensure continued production from the Tyra field. The new facilities could also enable future new production of oil and gas from the northern part of the DUC license area as well as third party projects.
“It is of course a great and very exciting project to be heading,” Pedersen says. “It will benefit not only Maersk Oil and the DUC, but also the Danish state as it protects jobs, security of energy supply and continued tax payments. It is a humbling experience and one which I am very proud to be a part of.”
A brighter mood
The city of Esbjerg, on the west coast of Jutland in Denmark, is all about oil and gas, and for Mayor Johnny Søtrup, the agreement on Tyra’s future is vital – and he can already sense a more cheerful atmosphere about the place as a result.
