Despite objections from Mayo locals, Shell said it had agreed to limit the pressure in the pipeline to bring gas ashore from the Corrib field to 144 bar, less than half the original amount.
Shell managing director Andy Pyle said the changes would see fewer clashes than have taken place outside the project’s terminal in Ballinaboy, north Mayo.
Previously raised issues about bringing the gas ashore had been “blown out of all proportion”, he said.
The pipeline will be 9.2km long and come ashore through a cliff face in north Mayo. It will be tunnelled under Sruwaddacon Bay into an area south of Rossport village. It will then go north-east crossing a local road and skirt along a bog before it comes back down and crosses under the bay again over a distance of a kilometre. Coming ashore again, it will cross over farmland, a small inlet and then into a forested area and into the terminal.
A threefold approval is needed for the route including from the Minister for Energy, the Department of Fisheries as well as An Bord Pleanála.
Construction could begin next spring if the pipeline is fully approved.
The route was drafted by consultants RPS after recommendations from mediator Peter Cassells.
