Sage  System

Via our wholly owned subsidiary SAGE North Sea Limited (SNSL), we operate the SAGE Gas Terminal Evacuation (SAGE) system, comprising:

–  the SAGE Pipeline including the Beryl leg; and

–  the SAGE terminal

 

The SAGE System is an integrated gas transportation and processing system which transports gas from the SAGE pipeline and Beryl leg to the SAGE terminal for processing. Sales gas is redelivered into the National Transmission System and natural gas liquids are exported into both the Forties onshore pipeline system and the SEGAL system. The SAGE terminal also processes gas from the Britannia pipeline.

We optimise the use of the SAGE System through safe and reliable operations, directly contributing to the energy transition, extending infrastructure life, connecting new fields and delivering strong financial performance.

 

Our ownership varies by asset component as shown below.

Notes

(1) The SAGE Terminal has amine treatment trains which can remove higher concentrations of CO2. Gas with higher CO2 concentrations may be able to be processed. Please contact the SAGE Operator for further information.

 

(2) Negligible means that the concentration must be below a level where the relevant species would:

(a) cause difficulties with transportation, processing, safety, facilities integrity in the SAGE System, downstream facilities or meeting redelivery specifications or derivative product specification, or

(b) impair the value or marketability of any ultimate products derived from feed gases entering the SAGE System.

 

(3) Gas outside this range of ratios may be able to be processed.

Please contact the SAGE Operator for further information
