Services we provide

We offer the following service levels to third-parties:


Gas and Liquids Transportation and Processing

  • Fields tie-in upstream of the Elgin/Franklin PUQ for processing.  Liquids are separated and exported via the GAEL system.  Gas is treated to sales specification on the PUQ and exported to the National Grid via the SEAL line.

Gas Transportation

  • Gas is tied directly into the SEAL line at a point agreed by the parties.  Gas entering the SEAL line will need to meet the SEAL technical specification.


The Elgin Process, Utilities and Quarters Platform (PUQ) is based on the TPG 500 jack-up concept. This is a self-elevating and self-piling jack-up installation with a triangular hull in plan view. The process system on the Elgin PUQ separates gas from condensate, treats the gas to sales quality and exports the treated gas and condensate through separate pipelines.  Additionally, the PUQ has installed water treatment capacity for about 25,000 BPD, after installation of compact flotation units in 2009, and gas compression power of 120MW. To power these services, the PUQ has a power generation capacity of 62MW (2 x 31MW).  A 90-person core crew operates the facilities with a maximum POB limit of 138 (bed limit).


The Elgin A, Franklin, Elgin B and West franklin well head platforms, are for well fluid collection and export only, all well fluids are processed on the PUQ. The Elgin A platform is linked via an 80m bridge to the PUQ with, the Elgin B platform linked to the Elgin A platform via a 95m bridge. The Franklin platform is connected to the PUQ via a 5.5 km interfield pipeline with West Franklin platform connected via a 5.2 km interfield pipeline to the Elgin B platform. All wellhead platforms are four legged and steel jacketed.

Liquids processing and export

Liquids are separated on the PUQ and treated to the GAEL entry specification. The liquids processing design capacity is 175,000 bopd.  The export route is through the 24” GAEL line to Forties Unity, and subsequently through FPS. The FPS, operated by INEOS FPS, provides liquids and raw gas processing services.

Gas processing and export

The gas treatment plant removes CO2 and H2S, controls dew point and calorific value and other characteristics, to meet National Grid delivery specifications.  The design capacity of the gas treatment plant is 15.5 Mm3/d.  Gas from Elgin and Franklin is exported 468 km through the 34” SEAL pipeline to the facilities reception and metering terminal at Bacton. The SEAL pipeline and SEAL terminal are currently operated by Shell.


Elgin/Franklin has an impressive performance record as can be seen from the operations efficiency chart below. Operations efficiency from January 2020 to August 2020 is 99.1%. TotalEnergies E&P work hard to ensure shutdowns are scheduled (as far as possible) to coincide with shutdowns of our export systems through close liaison with operators. These actions, along with comprehensive maintenance strategies help to maintain high levels of uptime for the platform.

Production Efficiency (Actual Production versus Planned Production – inclusive of planned shutdowns)

Unplanned shutdown for the majority of 2012 due to a force majeure event, however 89.1% Efficiency was achieved January - March. Facilities successfully resumed production in March 2013, Production Efficiency 2013 represents the period post March 2013.
