The pipeline project includes an approximately 83 km offshore section, which was completed in 2009, and a 9 km onshore section, which has just received approval.
The pipeline is planned to bring gas from the Corrib Gas Field, located 83 km off the northwest coast of Ireland, onshore.
Ireland currently imports 96 per cent of its gas supplies from Europe via an interconnector pipeline from the UK.
The Corrib Gas Pipeline is intended to secure Ireland’s gas supply in the event of political instability or an interruption of Russian gas supplies to Europe.
