FUNCTIONAL SAFETY

Process industry

For the safety achievement of industrial process plants (for example for chemical - petrochemical sector) can be used safety instrumented systems, normally composed by three subsystems:

  • Subsystem "sensor"
  • Subsystem “logic solver”
  • Subsystem "final element"

The SIL classification, the design, validation and use of these systems to achieve functional safety is regulated by the IEC / EN 61508/61511 standards.

In detail of these activities, in co-operation with certification bodies, CTAI can provide the following services:

  • Training courses on the application of standards IEC/EN 61508 and IEC/EN 61511
    • Requirements specification
    • Definition of the necessary documentation
    • Hardware and software design
    • Validation (integrity and functionality validation)
  • Courses for FS Engineer (TÜV Rheinland) qualification
  • Plant risk analysis
  • SIL classification of safety systems
  • Functional safety assessments of safety systems and devices
  • Software functional safety assessments
  • SIL certification of systems and devices used in safety systems
