Bord Gáis Éireann awarded the project management of a 6km pipeline to supply Aughinish Alumina. This included the design, material procurement, and planning of the pipeline and an above ground gas installation.
The pipeline is 6km in length and constructed from 300NB continuously welded carbon steel pipe. The pipeline design pressure is 85 Bar with a flow of 78,000 SCMH.
A gas pressure reduction station to reduce the pressure from 85 Bar to 4 Bar was built on Aughinish Island. This consists of heating, metering, filtering and pressure reduction equipment.
The station also services Aughinish Alumina with a design pressure of 25Bar and a flow of 78,000 SCMH.
From an environmental viewpoint, pipelines safely managed have minimal effect and ensure a security of supply to natural gas customers nationwide. The pipeline and pressure reduction station, became part of the transmission and distribution network.
