Safety lifecycle management at the line level is understood by the practitioners, but one of the main issues is learning how to get management buy in.
Those were just some of the thoughts shared Wednesday at the 2010 Emerson Global Users Exchange technology forum entitled “Safety Lifecycle Management.”
“A lot of the problems are not solved by technology, but do management and the entire organization buy into the concepts,” said Mike Boudreaux, DeltaV SIS brand manager.
“You have to have management buy in,” said Conrad Clark, senior consultant at Meridium. “If you can show him you can save his butt or you can show him you can save him money, then you have buy in.”
Boudreaux started off the session giving the three stages of safety lifecycle management. The stages include: analysis phase, implementation phase, and operations phase.
The analysis phase focuses on hazard and risk assessment; allocation of safety functions, and safety requirements and specifications for the safety instrumented systems.
It seems pretty basic, but during the analysis phase “the objective is to find the hazards that can happen – the HAZOP,” said Bill Goble, principal partner at exida. “We identify what can go wrong and then we write up a safety requirement specification.”
As it is with everything these days, “the objective is maximize safety while reducing costs,” he said.
“The HAZOP is necessary,” Clark said. “They are a valuable thing to do to keep things safe and they are always a work in progress.”
After some questions from the audience the consensus was consistency during the analysis phase is vital, but often not met.
The implementation phase looks at design and engineering of safety instrumented system; design and development of other means of risk reduction, and installation, commissioning and validation.
As a part of the design and engineering of the safety instrumented system component of the implementation phase, there are five areas to focus on:
• Select technology
• Select architecture
• Determine test philosophy
• Reliability evaluation
• Detailed design
“We need to make sure you can do whatever it takes for your needs to be implemented,” said Ed Smigo, director of systems technology at Proconex.
“Consistency through the implementation phase will allow for a more robust system,” said Keith Bellville, DeltaV product manager at Emerson.
“The goal of the implementation is to have procedures in place,” Boudreaux said. “You have got to have the procedures in place.”
The operations stage deals with operations and maintenance; modification, and decommissioning.
