Webinar Recordings A Tale of Two BPCS Credits, A Bayesian Case Study This case study examines the approach used for one client to justify two risk reduction credits on their robust BPCS interlock in two basic steps. The first step was to decide a reasonable probability of failure using a Failure Mode and Effects Analysis technique (FMEA). All relevant failure modes including the ubiquitous human component were examined. Next, plant operating history was reviewed and applied in a Bayesian analysis to determine the upper credibility (confidence) limit. The overall FMEA and Bayesian analysis process, including the "why," "how," and results will be provided. Presented by Keith Brumbaugh, P.E., CFSE • Principal Specialist - SIS FEL Identifying System Level Failures Using STPA Before They Occur The new hazard analysis method known as STPA - Systems Theoretic Process Analysis - and how it can help prevent accidents in the non-routine, abnormal, and transient operating states. Best Practices to Ensure My Risk Assessment is Trustworthy Part 3 of Trustworthy Risk Assessments, QRA, and Data Validation in Process Safety One of the most powerful features of the Safety Life Cycle (SLC) is validation of the Risk Assessment with actual performance data; this is the ‘cyclic’ aspect of the SLC. One of the largest sources of error in a Risk Assessment is applying generic “industry” data without validation, which can increase the frequency of incidents or the cost of controlling hazards. This final webinar of our three-webinar series shows how to leverage qualitative and quantitative methods to update Risk Assessment data including using probability distributions and confidence intervals. Capabilities of Quantitative Risk Assessment and Its Applications Part 2 of Trustworthy Risk Assessments, QRA, and Data Validation in Process Safety: Quantitative Risk Assessment (QRA) represents the "sharpest pencil" in the Risk Assessment tool kit for quantifying risk and crediting safeguards for risk reduction. In this second webinar of our three-part series we present applications for QRA, its utility for modeling dependencies, conditions where QRA provides value over other risk assessment techniques, and application of QRA in Bowtie Analysis. Presented by Joe Veasey PE, CFSE Choosing a Risk Assessment Methodology Part 1 of Trustworthy Risk Assessments, QRA, and Data Validation in Process Safety The ANSI/ISA 61511 Safety Life Cycle starts with a Process Hazard Analysis (PHA) and a Risk Assessment. This first webinar of our three-part series details the purpose of Risk Assessment and examines the advantages and limitations of various methodologies including Risk Graph, Layer of Protection Analysis (LOPA), Quantitative Risk Assessment (QRA), and others.

Pharma Company Detecting Natural Gas Leaks in Boiler House A pharmaceutical client determined they needed a natural gas leak detection and isolation system for a utility building based on a PHA recommendation. aeSolutions installed a combustible gas leak detection system to shut off the gas supply to the boiler, bringing the facility into compliance with the safety program requirements. Challenge A global pharmaceutical company’s corporate standards mandated a local manufacturing site install a combustible gas leak detection system in its boiler house to mitigate risk to personnel and equipment. The client needed the ability to detect and isolate gas leaks within a utility building containing multiple large natural gas-fired boilers to lessen the risk to personnel and reduce the potential for extended production disruption due to significant equipment damage. Solution aeSolutions designed and provided an FM approved industrial fire alarm and gas detection system to automatically isolate the main natural gas feed to the building when a leak is detected. aeSolutions also provided detector placement consulting services based on the physical location of potential leak sources. Delivered: • FGS 1300 fire alarm and gas detection/isolation system • Automatic isolation valve installed in natural gas supply line • Eight point gas detectors • Detector placement services Results The client now has an industrial grade system for detecting and isolating a release of natural gas, reducing the risk to personnel and equipment, and complying with their corporate safety program requirements. Learn more about how aeSolutions could help you with a similar gas detection project.

Advanced Regulatory Control - ARC Enlisting More Variables aeSolutions process control specialists solve problems with Advanced Regulatory Control (ARC) when single variable PID control is not adequate. Cascade, feed forward, ratio, Smith predictor, and override controls are standard methods to include an additional process variable in PID loops to compensate for process dead time, or non-linearity. Multivariable and model-based controls are employed for more complex process automation challenges encountered in chemical plants and refineries. aeSolutions helps the client's process engineers take advantage of the multivariable control capabilities found in the latest generation of DCS systems. These offer real time performance with multivariable models available at the controller's function library level. Automation Services Previous Next
