The crane on the process module at Tyra II has been put into permanent use, representing a milestone in the hook-up and commissioning campaign of the field redevelopment project in the Danish North Sea.
Norwegian Energy Company (Noreco) reported on 23 December that the crane on the process module (TEG) is in permanent use.
According to the company, the milestone was planned for early Q1 2023 and is as such achieved ahead of schedule despite the challenging weather conditions earlier this month.
The TEG crane is said to be important for the project as it enables an efficient completion of the remaining scope of the hook-up, commissioning and start-up of Tyra II.
The module is 47 meters tall, measures a total floor area of 16,300 square meters, and weighs 17,000 metric tons – equivalent to the weight of more than two Eiffel Towers.
The installation of the Tyra II process module , which broke the world record as the heaviest crane lift ever undertaken at sea, was completed in early October, shortly after which the last remaining piece of Tyra II puzzle was lifted into its final position.
At peak, the process module will be able to process 300 million standard cubic feet of gas per day which is coming from both Tyra and five unmanned satellite fields, namely Tyra Southeast, Harald, Valdemar, Svend and Roar.
TotalEnergies is the operator of the Tyra field on behalf of the Danish Underground Consortium (DUC) – a partnership between TotalEnergies (43.2 per cent), Noreco (36.8 per cent) and Nordsøfonden (20 per cent). It was discovered in 1968 and production started in 1984.
In 2016, the consortium announced the plan to cease production from the gas field by the end of 2019 and to redevelop the field infrastructure as the seabed had susided. The final investment decision was made in December 2017, following the approval by Danish authorities.
First gas is expected in the winter season of 2023/24. Once the modernized Tyra II is back on stream, it is expected to deliver 2.8 billion cubic meter gas per year, which amounts to 80 per cent of the forecasted Danish gas production.
