Tyra II resumes production

22-03-2024

Production from the new facilities on Tyra has been resumed, and the first gas has entered the export pipeline to shore. This is an important step towards getting the first gas from the Tyra facilities to the gas market. Tyra will thereby once again become a hub for gas in the Danish part of the North Sea. When production from the Tyra field and the surrounding fields is fully established, it will provide an important contribution to securing the supply of energy to Denmark and Europe.

Impressive engineering

The redevelopment of the Tyra field is one of Denmark's largest construction projects, and Tyra II is an impressive piece of engineering in terms of both size and complexity.

Design, construction and installation of the platform has taken a total of more than 10 years. Back in 2013, the natural subsidence of the reservoir, combined with new knowledge about wave effects, was the catalyst for the redevelopment of the Tyra field facilities.

Today Tyra II's eight platforms rise up to 54 meters above sea level as a high-tech town sitting upon pillars in the North Sea, 225 km from the west coast of Jutland. The platforms and bridges have been built around the world in yards in Italy, Spain, Singapore and Indonesia before being transported to the North Sea. In recent years, around 7 million working hours have been used offshore to make the facilities ready for operation.

"The redevelopment of Tyra has been a complex mega project, which has required a huge effort from all involved. Great praise must be given to all parties - from the welders and electricians offshore to the engineers and suppliers, and not least of course to the DUC operator, TotalEnergies, who has been responsible for the implementation of this colossal project", says Birgitta Jacobsen, CEO of Nordsøfonden.

"The facilities on Tyra II are some of the world's most modern, and safety and efficient work processes have been the focus of the design. An extra effort has been made to make the new accommodation platform a home away from home for the many employees who will work offshore. At the same time, the new platforms are so energy efficient that they will reduce CO2 emissions from gas production by up to 30 percent compared to the old Tyra facilities" continues Birgitta Jacobsen.

Security of supply increases

Due to the redevelopment, production and export from Tyra and the surrounding fields was temporarily shut-in in 2019. After the reopening, the facilities will once again function as a hub for the vast majority of the produced gas in the Danish part of the North Sea. At plateau, the Tyra hub will produce 5.7 mio. m3 of gas and 22,000 barrels of condensate per day.

"When Tyra II is back in full operation, Denmark will once again be a net exporter of gas. It is an important contribution to securing the energy supply for both Denmark and Europe, which in recent years has been challenged by the geopolitical situation", says Birgitta Jacobsen.

The work continues

Export from Tyra II have now been re-established, but there is still work to be done offshore. The work includes, amongst other things, re-opening further gas wells on the Tyra field as well as start-up of the satellite fields Valdemar, Roar and Tyra Southeast which must be brought on stream so that they once again can send oil and gas to the facilities on Tyra II.
