ITI has been awarded numerous contracts by a large manufacturer of hydrogen energy systems to design, supply and install control systems for various containerised water electrolysis plants located in the UK and overseas. In addition ITI provided a SCADA system which allows full local and web-based visualisation and control of electrolysis plants based on the client’s premises.
The ITI-designed systems provide:
Holistic view of all production and commissioning plants.
Smarter maintenance and diagnostics.
Remote control of plants.
Improved monitoring and analysis of production.
Alarm and event distribution to remote uses (including mobile devices).
Familiarity with the site and systems helped deliver the project on time and on budget
ITI's extensive knowledge was utilised to provide process control and safety systems which satisfy the client’s specific user requirements. Each system had unique safety and control requirements which necessitated individual specification and design.
Each ITI solution adhered to the clients’ specific functional safety and hazardous area assessments. The design utilised Siemens fail-safe PLC controllers and safety I/O modules with suitable SIL protection to meet a number of client defined Safety Instrumented Functions (SIFs). Intrinsically safe barriers were used to provide a safe interface to the hazardous area signals which originated in Zone IIC T4, and SIL safety contactors were used to isolate equipment under critical safety failure.
The ITIsupplied SCADA system was based on a Siemens WinCC solution. It incorporated remote TCP/IP access to sites, duplication of plant screens for visualisation and control of each plant and historian functionality for data logging and analysis.
The ITI's scope includes of:
Full design compliance with Ex/ATEX requirements
Design of HMI Mimic/Control screens for each plant
Installation and full commissioning of the SCADA at the client’s premises
Full support, including additions of new plants
Control hardware specification, design, build and test at ITI premises
Specification, design and configuration of system architecture, based on Windows Server and Virtual Machines/Clients, using a range of Siemens WinCC utilities
Installation of the control panels into the containerised system, including all electrical and instrumentation connections throughout including CompEx certification
