SIL in the Petroleum Industry

The course will give an introduction to the functional safety of safety instrumented systems (SIS), and the concept of “SIL” (Safety Integrity Level). This is related to requirements for safety instrumented functions (SIFs) that work as barriers in a processing plant. The course provides an overview of relevant standards (especially IEC 61508 and IEC 61511), including SIL levels, what the SIL concept covers and basic methods of calculation and interpretation of results for a single SIF. Participants will achieve an understanding of issues related to SIL and can participate in relevant discussions.

Target group: Recommended for people working with safety, technical safety, process safety and instrumentation, particularly within the offshore industry, but the principles will also be relevant for land-based processing industries..

Prerequisite knowledge: Basic process, system and safety awareness. Knowledge of process safety and/ or instrumented safety systems is an advantage.
