👏 Cross-team collaboration was at the heart of the recent successful delivery of our Derrykillultagh Boiler Upgrade for Gas Networks Ireland.
Murphy was contracted to deliver the boiler replacement project associated with the 75/7 bar gas transmission system in Northern Ireland. To ensure uninterrupted operations throughout the works, a temporary boiler system was installed, allowing the existing boilers to be safely removed and replaced with new units.
Our Northern Ireland Operations & Maintenance (NIO&M) team successfully degassed and decommissioned the existing boiler system, creating the foundation for the upgrade works. Colleagues from our NSWC and Pipe Fabrication teams then removed the existing pipework and carried out the fabrication, testing, inspection, coating, and installation of new fuel gas and vent relief pipework.
Our Electrical Services team completed the electrical installation, testing, and commissioning support for the new boiler system. They also delivered a new solar PV installation at the AGI, further supporting Gas Networks Ireland's commitment to reducing carbon emissions and improving sustainability.
Once the upgrade works were complete, the AGI was safely handed back to our NIO&M team, who successfully commissioned the new system while ensuring continuity of gas flow throughout the project.
This project is a great example of Murphy teams working together to deliver complex infrastructure projects safely, efficiently, and to the highest standards. Well done to everyone involved.
Our people make successes like this possible. Join the Murphy team and help shape the future of infrastructure. See:
