Our consultants have expertise in the wide range of technologies within safety-related control systems and experience of the tools & techniques to analyse such systems and assure their integrity. We provide chairman, facilitators & scribes and are familiar using TRAC and similar software to record & process assessment work on safety instrumented systems.
Commencing with a Hazard Analysis and development of the Safety Requirement Specifications (SRS), we use a range of methods to apply a SIL, including risk graphs, risk matrices and, most frequently, layer of protection analysis (LOPA). SIL targets may be supported by a Consequence Analysis. Safety Instrument Functions (SIFs) are then determined.
SIL assessment, validation and certification services are provided for IEC61508 and IEC61511 standards. We are also familiar with related industrial specifications such as IEC 61513 for Nuclear and BS EN 50126 / 50129 for railway applications.
Example projects include:
- Combined power and steam generation plants
- Oil production facilities
- Chemical processing plants
- Liquefied Natural Gas (LNG) storage facilities
- Synthetic rubber process plant
- Pipeline interconnections
- Hydraulic power units
- Various oil & gas downstream projects including pre-FEED studies
In addition to consulting and mentoring, we disseminate our detailed knowledge of IEC 61508, 61511 and 61513 through a range of functional safety and alarm systems management training courses.
