Total Awards Danish Tyra Platform Contract

French producer Total has awarded Emerson a contract to provide wellhead pressure monitoring technology to enhance safety during the three-year, $3.3bn redevelopment project, Emerson said November 25. Since production started in the 1980s, the seabed has subsided by more than five metres, reducing the air gap between the sea and the platforms.

In order to keep the Tyra field in production, Total is replacing the existing wellhead platforms with new and elevated topsides. The 13-metre-high jacket extensions and new topsides will be installed on top of the existing jacket structures.

Emerson technology will monitor wellhead casing pressures as a safety measure and transmit real-time data. With power and cable infrastructure unavailable, it said a wireless and battery-powered solution was required. Emerson will provide more than 200 Rosemount wireless pressure transmitters to be installed on the four riser platform.

The Tyra redevelopment project will ensure continuous production from Denmark's biggest gas field, while safeguarding Danish North Sea infrastructure. Once completed, Tyra is expected to produce more than 200mn barrels of oil equivalent. The current Tyra field has two production complexes, Tyra East and Tyra West, which are linked to satellite fields Harald, Roar, Svend, Tyra Southeast and Valdemar.
