Brownfield Development –

Tyra pieces falling into place

By Bartolomej Tomic yra – Denmark’s largest gas and condensate feld and main gas processing hub – was, a few years ago, on the verge of being decommissioned, which would have, according to report back

T then, wiped thousands of jobs.

The feld located 225km west of Esbjerg, consisting of two main centers Tyra East and Tyra West and fve satellite platforms, had been in production since 1984, and the off- shore facilities were approaching end of life, and the seabed subsidence had threatened the integrity of the sinking plat- forms, too.

Maersk Oil, the then operator, had spent millions of dol- lars reinforcing the Tyra structures over the years. However, it in January 2017, said the facilities were no longer safe for work, having sunk fve meters deep over the years, and warned it would shut down the feld for good on October 1, 2018, shoud no viable economic solution for the development of the feld be found.

The shutdown would have meant not just the end for Tyra, but also for the satellite felds and would have discouraged fu- ture drilling attempts nearby, leaving potentially discoverable resources stranded below the seabed.

Luckily, just a few months after the shutdown warning, an agreement was reached with the Danish government, paving the way for a full redevelopment plan and life extension for the Tyra project, as well as setting the ground for future ex- ploration nearby.
