Functional Safety

IPDS can provide experienced Process Safety Engineers and TUV-certified E&I engineers to support and/or lead the full life cycle process as detailed in BS EN 61511. We have a broad range of experience leading and supporting Process Safety Management reviews using a range of risk hazard analysis techniques, including LOPA studies to determine SIL gaps for the application of safety instrumented systems. Integrity level verification of the SIS design can be demonstrated using proprietary software that integrates an extensive device database with simplified fault tree analysis equations to provide significant cost and time savings. The balance between integrity and reliability is a function of the type of process you operate, to support this assessment the mean time to failure spurious (MTTFs) can also be assessed, ensuring that you are designing a system that not only meets your target IL, but also your reliability goals.

Both Batch and Continuous plant operations can be supported with hardware and architectural solutions that enable either end-to-end or a structured testing and inspection strategy to identify those undetectable dangerous failure modes.

Functional Safety

SIL function performance reviews can be supported to advise and guide the Client on how to manage their inventory. The development and collection of instrument taxonomy data can be supported to enable IL verification to be demonstrated analytically and subsequently supported with real time performance.

The development of a supporting competency management scheme to identify roles and responsibilities, measure key competencies and establish a training and assessment scheme to monitor individual and group performance.
