Project Profile

Location: 200 kilometres offshore the west coast of Denmark in the North Sea, Denmark
Value: US$800 million
Production: 20 million barrels of crude oil and 170 billion cubic feet of natural gas
Start-up Year: 2022

Located approximately 200 kilometres offshore the west coast of Denmark in the North Sea, Tyra is part of the DUC scheme to develop the Danish oil and gas fields since 1972. After the first discovery of the Dan field followed by Gorm and Skjold, Maersk and its DUC partners developed Rolf in the west side and Tyra on the east side. Over the years, Maersk and its partners deployed a complex of more than 30 platforms to support the wellheads and for processing the oil and gas before exporting them through 215 kilometres pipelines. The oil and gas processing platforms are concentrated in Gorm and Tyra. In the Danish Underground Consortium, the working interests are shared between: Maersk (31.2%), Shell (36.8%), Nordsofonden (20%) and Chevron (12%). AP Moeller – Maersk (Maersk) and its partners in the Danish Underground Consortium (DUC), Shell, Nordsofonden and Chevron have decided to invest US$800 million capital expenditure in a new offshore platform at the Tyra Southeast oil and gas field. 

The expansion project in Tyra is part of DUC program to increase the oil and gas production in Denmark. With Tyra Southeast, DUC should add 50 million barrels of oil equivalent (boe) to the Danish production over the next 30 years. This production should be split between: 20 million barrels of crude oil and 170 billion cubic feet of natural gas. In this phase, Maersk and its DUC partners have planned to invest US$800 million capital expenditure in the Tyra Southeast project. Maersk and its DUC partners, Shell, Nordsofonden and Chevron expect to start production in 2015 and to reach the peak of production of 20,000 boe/d in 2017. This Tyra Southeast project includes a:
- New unmanned platform
- Bridge to tie-in the existing Tyra central processing platform
- Wellheads and wellheads structures
- 12 additional wells
