- Supply and Installation of a Replacement SCADA System
- Merseytravel, the operating name of the Merseyside Integrated Transport Authority, own and operate two cross-river road tunnels, Kingsway and Queensway. The tunnels’ operation is supported by a number of independent computer systems. Each system monitors and controls various aspects of the tunnel infrastructure, usually through its own user-interface. This includes five SCADA systems based upon discontinued products totalling approximately 5,500 I/O points.
As part of its commitment to the safe and reliable operation of the tunnels, Merseytravel has adopted a vision that seeks to reduce the number of user-interfaces presented to its operational staff. One way in which this will be achieved is through the unification of existing SCADA functions onto a single SCADA platform. This will also integrate user interaction with a number of specialist systems, such as Automated Incident Detection, where appropriate.
Implementing this vision is seen as a medium-term objective for Merseytravel. This reflects the constraints of migrating installed systems on operational tunnels and the on-going replacement of mechanical and electrical (M&E) equipment connected to SCADA.
To support this vision Merseytravel is seeking the services of a Systems Integrator who is experienced in the design, implementation and support of SCADA and PLC control systems. The services will cover the supply and configuration of SCADA and PLC equipment and associated network, cabling, interfacing equipment and housings as necessary. Work will involve migrating existing control schemes, re-engineering a number of tunnel functions, integration of a number of specialist systems and implementation of new control functions resulting from new M&E equipment.
Merseytravel envisages that a unified SCADA platform will enable the control of operational functions covering; “traffic management” (such as lane control, variable messaging, public refuges and announcements etc.) and “environmental control” (such as ventilation, lighting, electrical supply etc.).
Merseytravel intends entering into a four year framework contract with a single supplier. This will be based upon an initial SCADA project specification and schedule of rates for future project work. The initial project will introduce a new SCADA system (with PLCs and control network as necessary) replacing a number of the current SCADA systems. Future projects are expected to finalise this migration as and when M&E equipment allows, and to introduce new control functions. In addition future projects may be undertaken to upgrade specific tunnel functions to achieve appropriate safety integrity levels (dependent upon separate assessment work to be undertaken by Merseytravel).
