Lomond Subsea Schematic

Lomond Map

Lomond platform is a steel jacket platform designed for two parallel processing trains to separate Lomond fluids into component phases: wet gas, condensate & produced water for disposal. A compact processing unit was installed on the platform’s main deck for processing Erskine fluids into the same component phases. Wet gas is exported through an in-field pipeline to the Central Area Transmission System (CATS) Riser Tower at the North Everest platform and onwards to CATS Terminal, Teesside. Condensate is exported in the same way to the CATS Riser Tower and onwards to Forties Pipeline System (FPS).

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).
