Vol. 431 No. 5

Written Answers. - Gas Interconnector Protection.

Peter Barry

Question:

27 Mr. Barry asked the Minister for Transport, Energy and Communications the backup or emergency procedures which have been built into the construction programme for the interconnector gas pipeline to guard against disruption or loss of supply caused by any interference to the pipe undersea, by accident or otherwise; and if he will make a statement on the matter.

Minister for Transport, Energy and Communications (Mr. Cowen)

The integrity and safety of the gas interconnector pipeline are key elements in the planning, construction and operation of the system. The technical specifications for construction and operation conform to the highest international standards. Trenching of the subsea pipeline will protect it from any external risks.

In the operational phase, the flow of gas in the system and all key operating parameters will be monitored continuously by remote telemetry methods. There will also be an annual inspection of the subsea pipeline route using advanced technology which will provide early warning of any adverse conditions arising.

In addition, BGE is developing detailed safety and emergency plans to ensure adequate response to deal with any unforeseeable incident involving the pipeline. During the period up to the eventual decline of the Kinsale Head reserves, sometime after the year 2000, we will enjoy the security of supply that comes from having two separate inputs to the gas system. Towards the end of that time, if we have not identified a new supply of gas at home, we shall have to look again at the need to provide additional security of supply. This might take the form of liquefaction and storage of gas, or even the importation of liquefied natural gas. In this context it is possible that a north-south link would provide security of supply to both parts of this Island.
