Intro
The Kristin installation is a semi-submersible production platform in the Haltenbanken area of the Norwegian Sea, producing gas and condensate since 2005. It serves as a processing hub and host for subsea tie-backs such as Tyrihans and Maria, with export connectivity to shore.
Field
The Kristin field, discovered in 1997, lies in ~370-m water depth southwest of the Åsgard area. Reservoirs are Jurassic sandstones with high pressure and temperature. It was developed with subsea templates tied back to the central platform. Production includes gas and condensate exported via pipeline systems to onshore facilities.
Facilities
Kristin’s semi-submersible platform processes hydrocarbons from multiple subsea wells drilled on four 4-slot templates. Primary separation of gas and liquids occurs topside; condensate is stabilised and routed to storage or to the Åsgard C storage vessel for shipment. Rich gas is exported via the Åsgard Transport System (ÅTS) to the Kårstø processing terminal onshore Norway, where further conditioning and liquids extraction occur. The platform utilities include gas compression to meet export pipeline pressure requirements, produced water handling, power generation, heat recovery, and safety and control systems. Subsea infrastructure includes flowlines and umbilicals connecting templates and satellite fields. Kristin also supports ongoing development tie-backs under the Kristin South project, extending field life and throughput.
