HAZARD AND OPERABILITY (HAZOP) STUDIES
The purpose of Hazard and Operability (HAZOP) analysis is to prevent the release of hazardous materials and energy, followed by mitigation of the consequences should a release occur. It is essential for the team to identify all the hazards of the process being studied, not just the most obvious ones. Our approach is to use a semi-quantitative HAZOP that incorporates Layers of Protection Analysis (LOPA) to assess the reliability and number of safeguards.
HAZOP is a brainstorming exercise in which individuals from different disciplines participate. It is vital for the HAZOP team to be limited in size (ideally six people or fewer, excluding the HAZOP facilitator and, if there is one, the HAZOP secretary).
It is difficult to establish a maximum and minimum number of participants in a Hazop and Operabiliy Assessment, since the various functions necessary may be assumed in different ways in different organizations. Nevertheless, and as a very general criterion, it is safe to say that a Hazard and Operability Assessment with fewer than three participants (excluding the HAZOP facilitator and secretary) cannot generate sufficient and meaningful discussion.
LAYERS OF PROTECTION ANALYSIS (LOPA)
Layers of Protection Analysis (LOPA) is a quantitative screening tool which provides a consistent, objective, and defensible approach.
A LOPA can be visualized as a series of slices of Swiss cheese, whereby each slice is a layer of protection with a varying number and size of holes representing flaws. A high-consequence scenario occurs only if at least one of the holes in each slice “line-up,” allowing propagation of multiple failures.
For components of a process-control system, such as safety instrumented systems and other components such as relief valves and rupture disks, it is important to know or estimate the probability of failure on demand.
Functional Safety for Process Safety
International standards such as IEC 61508 and IEC 61511 define functional safety requirements for electronic systems and industrial applications in an effort to ensure that organizations maintain robust protections for all their processes.
With our functional safety services, we carry out Functional Safety Assessments (FSA) to ensure that your SIS includes the required Safety Instrumented Functions (SIFs) and that these are effective and reliable and maintain the required Safety Integrity Levels (SILs) through all the Safety Lifecycle.
Our experts are knowledgeable and experienced in evaluating systems based on relevant international standards and thrive on collaboration with your team to improve your organization’s overall functional safety.
