Rerouting of existing services was completed following close liaison with Dublin County Council & IDA Ireland representatives.

PROJECT OUTLINE

This project entailed the extension of Nangor Road Above Ground Installation (AGI). The Capacity Upgrade included the installation and commissioning of a new 70-4bar Pressure Reduction Skid (PRS), associated Boiler & Instrumentation Kiosk and all associated civil, mechanical, Electrical & Instrumentation (E&I) and ancillary works.

The Works included installation of:

  • Extension to the existing AGI
  • Replacement of existing 70/4 bar skids
  • New Pressure Reduction System complete with GRP Building
  • Packaged Boiler Unit, Generator, and all associated pipework.
  • Fuel Gas Skid
  • Electrical & Instrumentation Upgrades

KEY CHALLENGES

The Project scope was to extend Nangor Road AGI in order to increase capacity to the GNI gas network.

Existing fencing was removed and the station was extended to the south. Bulk earthworks were required to reach formation level of the AGI extension with material levelled and regraded on the adjacent Grange Castle Business Park lands. Rerouting of existing services was completed following close liaison with Dublin County Council & IDA Ireland representatives.

The site team liaised continuously with GNI Operations to ensure that there was no interruption to gas flow in the ‘live’ section of the AGI. Projects within live gas stations require strict control under GNI Permit to Work systems. All operatives and staff were trained in safe Control of Operations at the outset of the Project.

PROJECT DELIVERY AND INNOVATIONS

No excavated material was removed from site throughout the project. Murphy worked with the Client to ensure material was reused and avoided transport to landfill. This had obvious cost and environmental benefits.

Through careful planning of the works Murphy succeeded in prefabricating a large quantity of components required off-site. This ensured that welding and coating could be carried out to the highest safety and quality standards in fabrication shop conditions rather than on-site.

KEY FACTS

Works carried out accident free.

No interruptions to the operation of the AGI.

All welding, inspection, testing and commissioning carried out through direct delivery.
