Tyra II - Redevelopment of the Tyra field
The Tyra gas field is located in the Danish part of the North Sea approx. 225 km west of Jutland's west coast. The field started production in 1984 and since then has supplied Denmark with natural gas. The field is currently undergoing a major redevelopment, where all facilities are being replaced with new state-of-the-art facilities and the existing legs of the platforms are being extended to ensure sufficient air gap clearance to the ocean surface.
The Tyra field is owned by Danish Underground Consortium (DUC) – a joint venture between Total Energies, Noreco and Nordsøfonden. TotalEnergies is the operator of the field and has a 43.2 % share, while Noreco has a share of 36.8 % and Nordsøfonden 20 %.
Before the temporary shutdown in fall 2019, around 90 % of the Danish offshore gas production made its way to shore through the Tyra facilities. The Tyra facilities are therefore a central part of the Danish oil and gas production infrastructure.
During the almost 40 years that the Tyra field has been in production, there has been a natural subsidence of over 5 meters in the seabed under the facilities - this has resulted in the facilities sinking correspondingly, and thus the air gap closing and the facilities getting closer to the ocean surface. It was therefore necessary to renew the facilities to ensure sound production in the future.
About 90 % of the total Danish gas production goes through the Tyra facilities
The legs on the Tyra platforms are extended by 13 meters to counter the subsidence of the seabed
The rebuild will result ind a 30 % reduction in CO2 emissions from Tyra's production
The Tyra redevelopment means that the production from Tyra II and the surrounding fields Harald, Lulita, Svend, Valdemar, Roar and Tyra Southeast will be able to continue in the future.
At the same time, a significant part of the infrastructure in the North Sea is secured. When production from Tyra II is resumed, the facilities will once again be the main hub for the vast majority of the gas produced in the Danish part of the North Sea and thereby help to strengthen Denmark's security of supply.
The redevelopment of the Tyra facilities will make possible a production of approx. 60.000 barrels of oil equivalent (BOE) per day, when production peaks. The production will be coming from both Tyra II and the surrounding fields.
Furthermore, the redevelopment will have a significant impact on the fields’ energy efficiency. When Tyra II starts production, the CO2 emissions will be reduced by 30 %, when compared to those before the redevelopment. Flaring from the field will be reduced by 90 %.
