Upgrade of PLC System Hardware for AGI Installation

Scope of works

To upgrade the existing PLC system hardware

Cetix have had a long connection with the pipeline linking Scotland to Northern Ireland, providing the control and monitoring systems for the AGI’s for over 25 years. This has involved several modifications, upgrades, and support over the years.

The most recent project involved the upgrade of one of the AGIs. This upgrade was unusual compared to previous upgrades as it included the design and supply of a new GRP kiosk with the addition of mess and welfare facilities. This AGI was in an exposed location and the years and weather had taken their toll. We haven’t supplied a kiosk for a while, it was great to work with Glasdon again. AGI’s are off the main utility grids so the addition of welfare and mess facilities are a welcome addition.

An obsolescence report that Cetix produced identified several systems that were in need of an upgrade. These ranged from the workhorse Rockwell PLC 5 with a ControlLogix system, the marshalling panel, the UPS and Transformer. A smooth installation and commissioning phase was assisted with decent weather ensuring a successful outcome.

“I would like to express my sincere appreciation and gratitude for the outstanding work carried out by Cetix in upgrading the Programmable Logic Controller (PLC) system at one of our Gas Transmission Above Ground Installations (AGI). The recent project was executed with exceptional professionalism and dedication. The team at Cetix exhibited an impressive level of technical expertise and were completely committed to meeting deadlines. Communication from Cetix was smooth and effective from project inception to completion and the highest standards of safety were adhered to. The professionalism and technical competence have set a high standard for our expectations in future projects. I am pleased to provide this positive feedback to acknowledge and recommend Cetix exceptional service.”
