Lomond

Lomond Subsea Schematic

Four-legged braced steel jacket, a combined wellhead/production /quarters platform, processing gas and condensate from the Lomond and Erskine fields, and exported via infield pipelines to the CATS (Central Area Transmission System) Riser platform at North Everest, from where it is exported to Forties and onto the CATS Terminal at Teesside.

INFRASTRUCTURE  INFORMATION

Entry Specification:

Produced fluids must be commercially free of odours, materials, sand and solids/fluids that might interfere or cause injury to the proper operation of the Lomond platform facilities; which for the avoidance of doubt shall include any material that would affect the merchantable value of Lomond products.

Exit  Specification:

To meet the required specifications of the Central Area Transmission System (CATS) for export gas and the Forties Pipeline System (FPS) for export condensate.

Outline details of Primary separation processing facilities:

The Lomond platform has a single processing train for Lomond fluids, and the Erskine Processing Module (EPM) train which processes Erskine fluids. Initial stage separation for the Lomond process is through a two-phase vertical separator; initial stage separation for the EPM process is through a three-phase horizontal separator.

Outline details of gas treatment facilities: For the Lomond process, a single gas train consisting of booster compression followed by TEG dehydration and export compression. A second parallel compression train has been positively isolated. For the EPM process, a single gas train consisting of TEG dehydration followed by export compression (with flash gas compression from the second stage separator).
