Total Exploration and Production (E&P) Denmark has awarded a contract to Emerson for its Tyra gas field redevelopment project in the Danish part of the North Sea.
Emerson will provide wellhead pressure monitoring technology to the gas field to enhance safety during the project redevelopment.
The Tyra field consists of Tyra East and Tyra West production centres, which are linked to five unmanned satellite fields, Tyra Southeast, Harald, Valdemar, Svend and Roar.
The redevelopment is being carried out due to seabed subsidence at the Tyra complex. Since 1980, the seabed has subsided by more than 5m reducing the air gap between the sea level and the bottom of the platforms.
To overcome this situation, Total has committed to replace the wellhead platforms with the installation of new and elevated topsides supported by 13m high jacket extensions. Total is investing approximately $3.3bn in the redevelopment, which is expected to extend the life of the Tyra field.
Emerson Automation Solutions Europe president Roel van Doren said: “Emerson’s wireless technology has been successfully deployed within offshore applications around the world, helping improve the safety of people and operations.
“The ability to offer a complete solution capable of providing real-time measurement and awareness to help Total monitor and respond to pressure changes safely was a key factor in the use of Emerson technology.”
During the two-year closure of the field, Emerson noted that it will monitor wellhead casing pressures as a safety measure during the installation of replacement platforms and topsides. According to Emerson, due to the unavailability of power and cable infrastructure, a wireless and battery-powered solution will be needed to monitor the wellhead pressure.
The company will supply more than 200 Rosemount wireless pressure transmitters for installation on the four riser platforms. They will transmit data to two Emerson DeltaV PK controllers that will be installed on the accommodation platforms. Data will be presented to construction workers locally and relayed to an onshore monitoring point, said Emerson.
