Frequently Asked Questions

1 What consents are required for the onshore pipeline?

Approval for the onshore pipeline is required from the following statutory bodies:

2 Where can I view the applications that have been submitted for approval for the onshore pipeline?

3 How was the proposed route selected?

The proposed route was selected following a rigorous evaluation and public consultation process which has taken 14 months including 11 months of public consultation. All of the short-listed corridors were evaluated against technical and environmental criteria as well as criteria identified by the community. The proposed route strikes the best balance between all of the selection criteria.

4 Why was the proposed route selected for the onshore pipeline?

The proposed route was selected as it strikes the best balance between community, environmental and technical issues. It is twice as far away from occupied housing compared to the previously approved route and clearly addresses the issue of proximity to housing raised by the local community. In addition to this, the operating pressure will be less than half the original design pressure. The route will also have minimal impact on the local environment including Sruwaddacon Bay and other designated conservation sites such as the Glenamoy Bog Complex.

6 Will the pipeline be safe?

Pipelines have an excellent safety recorded when designed and operated correctly. The original pipeline route was subject to an Independent Safety Review, commissioned by the Government in 2005. Advantica, the company who carried out this review found that the pipeline was safe but made a number of recommendations to further enhance safety. The main recommendation was that the pressure in the onshore pipeline be limited to 144bar and SEPIL has announced plans for a Landfall Valve Installation (LVI) which will ensure that the pressure is limited. Modifying the pipeline route, so that it is twice as far from occupied housing, is in addition to this recommendation.

7 What pressure will the pipeline operate at?

The normal operating pressure of the Corrib Onshore Pipeline will range from 90 - 110 bar.  As the Corrib gas reservoir becomes depleted, it is expected that the operating pressure will fall to 60 bar after 4 years of operations.  In accordance with the recommendations of the Advantica Safety Review Report, the operating pressure in the Corrib Onshore Pipeline will be limited to 144 bar.

8 What does the Gas contain?

The gas in the Corrib Gas Field is a very pure form of gas, consisting of approximately 97% methane/ethane, which is similar to that transported through gas transmission pipelines, as reported by Advantica Ltd consultants. The gas contains small amounts of water and condensate (hydrocarbons in liquid form very similar to a light oil e.g. diesel/ kerosene). Read more.
