Recordings of aeSolutions webinars on process safety, automation, and burner management / combustion systems. Subject Matter Experts sharing their industry experiences. 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.

Distributing Monitoring and Control Network Design Distributing Monitoring and Control aeSolutions designs industry standard as well as vendor specific networks for distributing controllers, I/O, data servers, and operator stations. Networks like Industrial Ethernet can be a composite of cables, fiber optics, and wireless systems, with managed switches and routers. aeSolutions recommends products and standards that we have tested for reliability, bandwidth, redundancy, distance, and industrial environments. Access points between the wide area enterprise networks and the critical control system networks must be managed carefully. Installation quality and signal testing are critical to achieving a fast, reliable control network. • Distributed I/O networks • Controller communication networks • HMI servers and client networks • Switches, routers, and firewalls • Single mode and multimode fiber optics • Coaxial and twisted pair cables • Drawings and Bills of Material Automation Services Previous Next

Moving up with Modernization Migration Solutions Moving up with Modernization Many clients are faced with moving their safety and control systems to a newer platform, sometimes to a different vendor. aeSolutions offers project services to assess system options and define an architecture that best serves the client's needs. Then the project stages described under "Automation Services" will shepherd the migration through definition, design, installation, and startup. Migrations offer opportunities to realize a maximally integrated safety and control system, with great benefits for functionality, operability, safety, maintenance, and engineering productivity. These migration projects, with careful planning can be done in phases, such as replacing operator consoles first. Finally, migrations usually involve moving from obsolete systems to newer generation platforms. aeSolutions' clients are encouraged to embrace the enhanced technology and take advantage of the opportunity to add improved process automation and modernized human interfaces.

A process that evalutes equipment and/or the logic solver and associated software together during and after the assembly process to ensure it satisfies the requirements of the design specifications and safety requirement specification (SRS). FAT is typically conducted to assess for any deviations or abnormalities during testing. The ISA/IEC 61511 standard (Clause 13) requires that the need for a FAT should be identified during safety planning for a project, and also provides guidance on how a FAT should be planned and conducted. aeSolutions SIS engineers have the experience to develop these plans, oversee their execution as an independent 3rd party, or execute these tests. aeSolutions operates its own FAT lab -- a 10,000 square foot FM approved and UL 508a certified panel fabrication and testing facility -- to ensure any potential panel issues are resolved prior to shipping the system.

Layers of Protection Analysis (LOPA) is a semi quantitative method of risk assessment analyzing the frequency of occurrence of events that can produce a hazard associated with handling of hazardous chemicals. LOPA considers the applicability of safeguards, the potential for individual layers of protection to fail, and the potential consequences that are consistent with the organization's risk tolerance. During LOPA, Independent Protection Layers (IPLs) are identified. Claiming credit for one or more IPLs that do not provide the protection claimed will result in under-designed SIFs, increasing risk to the facility. Claiming less credit for IPLs than is actually provided will result in over-designed SIFs, increasing capital cost. aeSolutions has the expertise and experience to help you perform this critical task most effectively.

Two-out-of-Three (2oo3) Voting is a safety mechanism where three independent sensors or inputs are used, and at least two must agree to initiate a specific action, such as shutting down a process. This redundancy enhances reliability and reduces spurious trips.
