Practical Safety Integrity Level Determination and Verification Training Course – Langkawi, 7–11 Nov 2027

Overview

The Practical Safety Integrity Level Determination and Verification Training Course is a one-week course for instrumentation engineers, process safety specialists, and control systems professionals who leave with a SIL assessment and loop verification dossier to govern critical safety instrumented functions. Process facilities frequently struggle with subjective risk ranking, inaccurate failure rate assumptions, miscalculated proof-test intervals, and unverified architectural constraints under IEC 61511. This course resolves these challenges through calibrated risk graphs, quantitative Layer of Protection Analysis models, and rigorous Probability of Failure on Demand calculations. Agile Leaders Training Center delivers the Practical Safety Integrity Level Determination and Verification Training Course.

Who Should Attend

• Process safety engineers responsible for hazard identification, risk reduction factor targets, and safety instrumented function definitions.
• Instrumentation and control engineers designing safety instrumented systems, interlock architectures, and loop logic solvers.
• Operations integrity leads managing bypass permits, safety override logs, and operational risk assessments.
• Maintenance reliability specialists scheduling proof tests, analyzing equipment failure rates, and maintaining field device diagnostics.
• Capital project managers overseeing safety lifecycle deliverables, vendor reliability data packages, and safety requirement compliance.

The course assumes participants actively interpret piping and instrumentation diagrams, process hazard analyses, and instrument loop sheets, and it leaves out introductory sensor wiring and basic industrial electronics.
