Sleipner B functions as a subsea wellhead and collection point for production wells drilled in the Vest area. Fluids from B are piped ~12-km to the Sleipner T gas treatment platform or the main Sleipner A hub for separation and processing. It does not have extensive processing capacity onboard; instead, unprocessed wellstreams are routed to connected platforms for CO- removal, dehydration, and compression. Control and power for B come via umbilicals from A, enabling remote operation and periodic maintenance visits by helicopter. Subsea infrastructure includes flowlines, risers and control cables tying B to adjacent facilities. The structure includes safety and emergency shutdown systems, corrosion protection, and minimal utilities such as lighting and local instrumentation. Produced gas is routed into the Gassled export network serving continental European markets, while condensate is piped ashore for processing. Sleipner B's unmanned status reflects optimisation for the mature field's operations and efficient control from central hubs.
