Southwark
The Southwark platform is a fixed steel, normally unmanned gas production facility in the UK Southern North Sea, installed around 2021 as part of the Saturn Banks Project. Serving the Southwark gas field, it ties into the regional export network feeding the Thames/PL370 pipeline system to the Bacton Gas Terminal.

Field
The Southwark field sits within the Saturn Banks Project cluster of Rotliegend sandstone gas reservoirs in the Southern North Sea. It lies near Blythe and Elgood fields, with development aimed at efficient hub-based export using existing trunk infrastructure offshore and onshore to Bacton.
Facilities
The Southwark platform consists of a fixed normally unmanned structure with multiple well slots (typically ~3 wells) targeting gas and condensate. Subsea flowlines connect individual wells into the platform's manifold. Production fluids are routed through basic separation and metering facilities with control tied back to onshore operations. Export gas is transmitted via a short surface laid pipeline (~5.9 km) to the Thames pipeline (PL370) connection point and then onshore to the Bacton terminal. Processing equipment on Southwark focuses on bulk liquid knock-out, metering, and flow conditioning for pipeline requirements. The platform's utilities include low-power control and remote SCADA linkages, emergency shutdown systems, chemical injection for hydrate control, and minimal power generation suited for unmanned remote operations. Structural design accounts for North Sea environmental loads with suction pile foundations and redundant safety systems for remote operation.
