Leman AC

A fixed bridge-linked compression and utility jacket in the Leman Alpha complex (Block 49/26), ~48-km northeast of Bacton. Part of the Alpha hub handling natural gas from surrounding Leman installations. Typically attended when needed but operates integrated with the Alpha complex for gas processing and export.

Production: Gas

Operations start: 1968

Water depth: 36 m

Country: UK

Block: 49/27

Type: Fixed steel jacket

Field

Part of the Leman gas field, a Permian Rotliegendes sandstone dataset in the Southern North Sea discovered in 1966. The field produces dry gas that is routed to central processing hubs like Leman Alpha and onward to the Bacton Gas Terminal.

Facilities

AC functions primarily to provide gas compression and support utilities for the Alpha hub. Together with AP, AK, AD1 and AD2 it forms part of a cluster of bridge-linked jackets that centralize bulk liquid separation, multi-stage compression, dehydration and fiscal metering before exporting gas via the Leman pipeline to Bacton. Shared services include power generation, chemical and export pumps, and produced water handling. AC and its mates distribute power, control and safety systems across the Alpha complex, integrating flowlines from normally unattended installations.
