What is SIL & LOPA?
Safety integrity level (SIL) is defined as a relative level of risk-reduction provided by a Safety Function, or to specify a target level of risk reduction. In simple terms, SIL is a measurement of performance required for a Safety Instrumented Function (SIF).This is qualitative tool.
Layers of protection analysis (LOPA) is a powerful analytical tool for assessing the adequacy of protection layers used to mitigate process risk.LOPA is semiquantitative tool.
Because SIL has a simple number scheme to represent its levels (1–4), a high-level understanding of each level is typically all that is necessary to convey SIL at management levels. This saves management from having to understand the technical aspects of SIL, while allowing them to discuss their concerns

What we offer?
We carry out SIL & LOPA study for all type of plants as per IEC61508. The study includes preparation of Risk Matrix, Allocation of SIL levels, conducting review of these SIL levels and submission of the report of SIL study.
