The Tyra Redevelopment project is, to date, the largest project carried out on the Danish Continental Shelf, and is expected to increase net production by 90 percent and unlock gross reserves in excess of 200 mmboe. Redeveloped Tyra will decrease OPEX significantly and lower emissions at the field by 30 percent. In addition, the completed project will extend field life by 25 years and produce enough gas to power what equals to 1.5 million homes in Denmark

In 2016, The Danish Underground Consortium announced its plan to cease production from the Tyra gas field by the end of 2019 and to redevelop the field infrastructure. The Tyra hub required redevelopment due to compaction of the chalk reservoir, where the seabed has subsided by 6 metres over a period of 30 years of production. The redevelopment project was necessary to ensure that both crew and equipment are safe, as well as maintaining an efficient level of production. The final investment decision was made in December 2017, following the approval by the Danish authorities. The execution of the project is both a global and local effort. In addition to fabricating installations in both Europe and Asia, project efforts are being executed locally in Esbjerg and offshore in the Danish North Sea. The scope of the project includes removing old facilities, modifying existing ones, and installing new features. The 2 existing process and accommodation platforms will be replaced by 1 new process platform and 1 new accommodation platform. The 4 wellhead platforms and 2 riser platforms will have their jackets extended by 13 meters and the current topsides will be replaced.

(40,000 tons topsides and 10, 000 tons substructure)

The recycling of the old Tyra topsides at M.A.R.S. is the largest recycling of offshore installations in Denmark’s history and 95 percent of the old facilities are expected to be recycled.
