The SAGE System is an integrated gas transportation and processing system transporting gas from the Beryl pipeline and SAGE pipelines to the SAGE Terminal for processing and redelivery of natural gas into the National Transmission System and natural gas liquids into the Forties onshore pipeline system and the SEGAL system.

The Scottish Area Gas Evacuation (SAGE) Terminal, SAGE pipeline and Beryl pipeline, together the SAGE System, are core to our strategy. Our objective is to maximise throughput of the SAGE System through safe and effective operations, extending infrastructure life, connecting new fields and delivering strong financial performance.

SAGE North Sea Limited appointed Wood plc as its operating partner for the SAGE system.
