Recorded Webinars: Accounting for Batch Operation in SIL verification
Many industrial processes operate in Batch mode, i.e., a process where only limited quantity of product is generated at a time. The on/off behavior of a batch process provides unique opportunities to more frequently test SIF equipment. But how doe you take this into consideration in SIL verification? What is the probability of failure when the process if not running? exSILentia 4.11 introduced the ability to model batch processes directly within the SILver module. This webinar will look at aspects to consider when accounting for batch operation in SIL verification. The webinar will also review some more challenging batch operation scenarios and wasy to evaluate those in more detail.
Blog Entry: Pipeline Safety and Security – Why are we still not prepared?

Recorded Webinars: How can I use my PHA to Streamline Cybersecurity Risk Assessment?
Many organizations have mature processes in place for evaluating process or machinery hazards in traditional safety risk assessments, but fewer have developed a robust approach to cybersecurity risk assessment. Alignment between safety risk assessment and cybersecurity risk assessment is critical, and the 2016 version of IEC 61511 now requires that a cybersecurity risk assessment be conducted for all Safety Instrumented Systems (SIS) and connected systems. Fortunately, traditional process hazard analyses (PHAs) have valuable information that can be used to improve the speed and efficiency of the cybersecurity assessment, including corporate risk criteria, potential consequences resulting from control system failures, severity rankings for consequence scenarios, existing mechanical protection layers. With this information organizations can jumpstart their approach to managing cybersecurity risk.
