Overview
exida has the world’s leading tool for supporting safety lifecycle tasks (exSILentia®). exSILentia® has its own embedded failure rate database, based upon 160 billion operating hours of failure rate information.
exida embeds years of expert knowledge and data into each of their engineering tools.
Whether you are performing PHAs (PHAx™), LOPAs (LOPAx™), SIL Selection (SILect™), SIL Verification (SILver™), SRS creation or Proof test procedure development, cyber risk assessment (exSILentia Cyber) or alarm rationalization (SILAlarm), exida has a tool to suit, either as a standalone or part of an overall integrated suite that works seamlessly to provide the most comprehensive tool on the market today. You save time and money, while increasing efficiency and productivity.
Software
Streamline the Process Safety Management work process and the Safety Instrumented System Functional Safety Lifecycle.
exSILentia® streamlines the Process Safety Management work process and the Safety Instrumented System Functional Safety Lifecycle by providing:
• Easy to use best-in-class tools
• Intelligent lifecycle knowledge integration
• Ground breaking enterprise leverage
Industrial Control System Cybersecurity Risk Assessment Tool
exSILentia Cyber helps to streamline communication across an organization and between different departments when performing cyber risk assessments. It provides a standardize approach across all disciplines while aligning cyber security activities with overall corporate risk criteria.
Alarm Rationalization with SILAlarm
SILAlarm™ is a tool for facilitating and documenting the results of alarm rationalization in a master alarm database. It was developed in accordance with the ISA-18.2 standard “Management of Alarm Systems for the Process Industries” and EEMUA 191. SILAlarm™ guides a rationalization team through a systematic, tailorable process of reviewing, justifying and documenting the design of each alarm.
Maximizing Risk Reduction through Collection and Analysis of Operation & Maintenance Data
SILStat™ is exida’s Life Event Recorder tool. It allows you to capture key operational and maintenance data (such as equipment failures, process demands, success or failure of protection layers, proof test results, etc.,) for review and analysis as required by the IEC 61511 / ISA 84.00.01-2004 standards and as part of compliance with an OSHA PSM Mechanical Integrity Program.
Training
We offer a range of tool training courses for professionals in the process industry, from basic to advanced concepts. We also offer customized training options available upon request.
Students benefit from exida’s in-depth knowledge and expertise, enabling them to fully understand how to use their powerful engineering tools effectively and efficiently.
ALM 241 - Alarm Rationalization with SILAlarm
Attendees will learn how to conduct alarm rationalization of greenfield (new) or brownfield (existing) applications in order to optimize performance of their alarm systems. The class immerses participants in discussion and hands on exercises which have been designed to demonstrate the best practices and requirements for rationalization as taken from the ISA-18.2 alarm management standard and EEMUA 191 guideline. The class focuses on how rationalization can lead to improved operator performance by eliminating / preventing common alarm problems such as nuisance / chattering / stale alarms, incorrect priority, alarm overload, and alarm floods. It also includes a discussion on tips and tricks for creating an alarm philosophy document, such as how to effectively define the “rules” for rationalization. Exercises will use exida’s SILAlarm rationalization tool.
FSE 242 - Process Hazard Analysis with PHAx
FSE 242 details how the exSILentia PHAx™ module can be used to conduct HAZOP methodology based Process Hazard Analysis. This course is targeted towards students that are experienced in process hazard analysis who want to learn how to leverage the advanced features of PHAx™. It will cover how to configure a project, define risk criteria, and use the advanced libraries to store valuable project specific information. The students will learn how to define units, nodes, and how to benefit from the PHAx™ smart deviations. It also addresses how hazard scenarios are to be defined for use in subsequent lifecycle phases.
FSE 243 - Layer of Protection Analysis with exSILentia®
FSE 243 explains how the exSILentia LOPAx™ module is used to conduct a Layer of Protection Analysis. This course is targeted towards students that have a general understanding of layer of protection analysis and safety requirements specifications who want to learn how to leverage the advanced features of LOPAx™. It will cover how to analyze hazard scenarios considering the frequency of initiating events and the probability of failure for each independent protection layer (IPL) as well as enabling conditions and conditional modifiers. This course will show how to calculate the required Risk Reduction Factor of an IPL and identify Safety Instrumented Functions (SIF). It will teach users how to transfer data from PHAx™ to LOPAx™.
FSE 244 - SIL verification with exSILentia
FSE 244 explains how the exSILentia SILver™ module is used to perform a SIL verification for Safety Instrumented Functions. Students will learn to leverage the tool to model different SIF architectures ranging from simple 1oo1 configuration to more complex examples. This course also covers review of the key parameters that determine the probability of failure of a SIF as well as minimum hardware fault tolerance and systematic capability aspects. It will show the impact of these parameters on the detailed design, implementation, and operation of the SIF. Furthermore, students will learn how to transfer data from the SILver™ module to the Design SRS module and subsequently complete the Design SRS requirements. Finally, the course covers the impact of proof testing and specification of proof test procedures using the Proof Test Generator module.
