Client Case
Future-proof pilot project
- IEC 61511 Compliancy, Process Safety
What
Governmental Seveso audit focusing on Safety Instrumented Systems. Failed to demonstrate state-of-the-art compliance for the evaluated safety instrumented functions.
Solution
Reverse engineering of the evaluated safety instrumented functions according to the IEC 61511 standard.
-
Evaluation of the HRA including review of P&ID, SIL and proper independence.
-
Interactive workshop to develop a Safety Requirements Specifications template accommodating the requirements for the safety instrumented functions.
-
Verification of the achieved SIL supported by PFDavg calculations and challenging the feasibility of the overall plant parameters like the periodic test interval and level of in-depth testing. Reviewing alignment and consistency with the logical and electrical drawings.
-
Drafting new validation and periodic proof test sheets with proper pass/fail criteria for the operator.
-
Proper V-model integration by witnessing the new proof tests and thus making sure the safety instrumented functions are in line with the Safety Requirements Specifications.
Results
Competence boost
The workshop-based approach gave us the opportunity to introduce the project team to the extensive list of requirements needed, including the impact of critical requirements on the operational phase. It facilitated a one-team approach during the complete project duration. We logged the competences of the project participants to ease the mandatory competence management.
Cost-saving
In-project specific training resulted in both Engineering and Operations gaining clear insights and better understanding of limited extra capital investments in relation to the mid-term wins on operational cost of safety instrumented functions.
Future-proof
During the project we captured quick-wins and possibilities to improve, work smarter and save costs on future projects. All the templates and tools used are set with generic-driven focus, providing maximum scalability in upcoming safety work.
