Safety Instrumented System Functional Safety Assessment Experiences
By Jon Keswick, CFSE - 12 April 2019
Functional Safety Assessment is a dry topic at the best of times, so much so that I took it as a personal challenge to try and write a paper about it!
The paper highlights experiences from several different projects and concludes with some simple recommendations to save time, money and mistakes.
The paper features at the IChemE Hazards 29 conference, taking place in late May 2019 (details at the foot of this page). The full paper will be published here after the conference, so until then, here's a quick abstract.
Given that the process industry now has more than fifteen years of experience with the functional safety life-cycle, it is not unreasonable to expect that there have been some improvements in the specification, design, testing, operation, maintenance and modification of Safety Integrity Level (SIL) rated safety systems.
There are, however, significant challenges in demonstrating conformance with functional safety standards for the design and testing of new safety systems, and even greater challenges for existing safety systems which require modification. Independent functional safety assessment and functional safety audit should highlight when non-conformances are occurring.
This paper will seek to describe some of the challenges that were witnessed at first-hand during functional safety assessments, functional safety audits, and in general during projects involving Safety Instrumented Systems (SIS) during the past ten to fifteen years.
It is hoped that by sharing experiences of real-world functional safety assessment and audit non-conformances, duty holders, engineering service companies and equipment suppliers will be able to learn how to avoid costly re-work and potentially dangerous weak-link designs.
The full Paper will be delivered from 15:55 to 16:20 on Thursday 23rd May 2019 at the International Convention Centre in Birmingham, UK. See below for links to the conference programme and registration.
About the Conference
Europe's largest annual process safety conference will take place on 22 to 24 May, 2019 at the International Convention Centre in Birmingham, UK.
The conference will cover every major aspect of process safety and bring together hundreds of practitioners from around the globe. It's the perfect place to learn from others' experiences, keep up-to-date with good process safety practice, and network with the international process safety community.
