CASE STUDY: The Jack Lynch Road Tunnel, Cork, Ireland – Voice Comms systems 2015

“The design, development installation and commissioning of a fully integrated plant, environment and traffic control & monitoring system, installed and supported in Ireland.”

Info

Since 1999 we have provided long term maintenance and call out support to Cork Corporation and also several upgrade projects.
“a great bunch of guys who go the extra mile”, Dermot Woods, TII/Cork City council.

The Jack Lynch Tunnel runs under the River Lee in Cork, Ireland, and comprises 2 traffic lanes in each direction together with a central service and emergency pedestrian access.

Our original project in 1999 was for the design, development installation and commissioning of a fully integrated plant, environment and traffic control and monitoring system, and involved interfacing the following plant equipment into a fully integrated control and monitoring system, including; Matrix, VMS and prism traffic signs; 24 main tunnel jet fans; Tunnel lighting; Interfacing with loop based traffic monitoring; Emergency telephone system; Monitoring access to tunnel emergency equipment and Interfacing of the CCTV system. The overall control system arrangement includes 3 hot-standby PLCs; a further 8 distributed PLCs; a two way PLC communication network, and multiple operator terminals for Tunnel Operators; Area Traffic Control and a Garda (police) terminal. Scope on this project was extended to include the technical management of the other specialist sub-system contractors, to ensure full integration of the data from those sub-systems into the user interface.

New SCADA and Voice Comms systems – 2015

This involved the upgrading of the existing voice communication systems to enhance the existing UHF radio coverage and associated FM voice break-in system; changing the existing tunnel Emergency Roadside Telephone system to a Voice over Internet Protocol (VoIP) based system; upgrade the associated fibre based Ethernet network installation and provide additional remote operator facilities at the Dublin Port Tunnel some 170 miles away.

The project was required to meet or exceed the specified requirements without loss of Public Voice communication functionality and in a safe and coordinated manner.

The project was implemented with no downtime to specified systems, and with less closures (and therefore less disruption) than originally planned.

A supported approach.

At PDS our philosophy is to support you from the initial concept through all stages of a project, and to be able to continue that support through asset life, servicing every aspect of your needs from our own team or with our partner companies.
