Tunnelling on Corrib pipeline to commence by year’s end

Connaught Telegraph

 TUNNELLING work on the 4.9km route under Sruwaddacon Bay in north Mayo for the Corrib onshore pipeline is expected to get underway by get end of the year.

The tunnel boring machine ‘Fionnuala’ has arrived at Aughoose and will be assembled and mechanically and electrically fitted our in the coming weeks.

It is estimated that the tunnel – which will be the longest in Ireland and the longest tunnel for a gas project anywhere in Europe – will take approximately 15 months to complete.

The contract for this work is a joint venture between BAM Civil from Kill Co. Kildare and Wayss and Freytag Ingenieurbau AG, a German tunnelling specialist a subsidiary of the BSM Group.

Construction of all support facilities at the Aughoose site is now always complete, with work still going ongoing at the shaft in preparation for the launch of the tunnel boring machine.

Work is also well underway by Roadbridge Ltd., on the construction of a stringing yard where the pipeline lengths will be welded together into 84 metre long sections before being inserted into the tunnel.

Twenty-four hour working seven days a week is underway at the Aughoose site since mid-October and will continue until the tunnelling process has been completed.

Strict conditions are laid down in the consents and permits for this phase of work in relation to noise and light.

Rigorous monitoring is undertaken by SEPIL on a daily basis to ensure that least possible impact on the local community.

The results of all monitoring are also submitted to the authorities on a regular basis and the sire is subject to oversight visits by Mayo County Council and by independent consultants employed by the Department of Communications, Energy and Natural resources.
