Lifecycle Safety Instrument Systems First Edition

by David R Ransome

P & I Design Ltd have been associated with providing clients with support for their process instrumented safety systems for over 30 years. Initially, called high integrity systems and then designed in accordance with the guidelines of PES. More recently, the design and lifecycle of Safety Instrumented Systems is required to be in accordance with the International Standard IEC 61508 and IEC 61511.
We have been associated with the Storage Industry for over 25 years.
Our clients being many of the member companies of either the Tank Storage Association (TSA) or United Kingdom Petroleum Industry Association (UKPIA).
Following the explosion at the Herefordshire Oil Storage Terminal on 11th December 2005. we have worked closely with industry, the trade associations and the regulator to provide assistance in ensuring process safety is paramount within the industry sector. This work includes being part of the Buncefield Standards Task Group (BSTG), Process Safety Leadership Group (PSLG) and Chemical and Downstream Oil Industry Forum, producing guidelines for risk assessment and Safety Instrumented System Design.

With our multi-disciplined team, we can provide customer support throughout the IEC 61511 lifecycle phases. Including Risk Assessments utilising HAZOP, LOPA and the use of process modelling software to simulate process changes and disruptions, through design, commissioning, validation and operational support.

This document will present a summary of a practical life cycle approach to Safety Instrumented Systems (SIS) for the Storage Industry.
