Engineering Tools

Save time and money, while increasing efficiency and productivity.

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 (PHAxTM), LOPAs (LOPAxTM), SIL Selection (SILectTM), SIL Verification (SILVerTM), SRS creation or Proof test procedure development, cyber risk assessment (CyberPHAx) 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.

Products


exsilentia

Design, operation and maintenance of Safety Instrumented Systems (SIS)

exSILentia helps users achieve a new level of consistency and productivity in the design of their Safety Instrumented Systems (SIS). 

All-new functionality allows users to follow the entire IEC 61511 / ISA 84 functional safety lifecycle for the first time using a single tool. It also supports compliance with regulations such as OSHA PSM 1910.119 (USA) and Seveso II (Europe).

PHAx

Conduct efficient PHAs with PHAx

PHAx guides users through the HAZOP process, effectively focusing the user on the task at hand, identifying hazards, hazardous events, and associated sequence of events, using a non-traditional approach. PHAx allows the user to document the relevant and important facts.

cyberphax

Conduct Efficient Cyber Risk Assessments using CyberPHAx™

CyberPHAx™ is a PHA based tool that can be used by engineering personnel in project, process safety, information technology, and process control, as well as plant management, and operations personnel. 

CyberPHAx guides users through the Cyber Risk Assessment process, effectively focusing the user on the task at hand, identifying types of cyber-attacks, potentially leading to hazardous events and their associated risks.

silalarm

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.

SILStat

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.

LOPAx

Layer of Protection Analysis (LOPA) Software

LOPAx™ is a Layer of Protection Analysis (LOPA) tool that can be used by process, process safety, and control engineers in support of plant management and operations personnel. LOPAx guides users through the LOPA process. A hazard scenario consisting of a single or multiple Initiating events can easily be evaluated. Multiple Enabling Conditions (EC), Independent Protection Layers (IPL), and Conditional Modifiers (CM) can be specified. The effectiveness of each can be specified on a per initiating event basis, allowing the user to thoroughly document the sequence of events that cause an initiating event to become an incident.

Our portfolio includes software tools for process hazard analysis (PHA), alarm rationalization, and Safety Instrumented System (SIS) Design. Our flagship product (exSILentia®) is the world’s best-selling tool for SIL Verification.

Tool Training Courses

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 effieciently.

Alarm Rationalization with SILAlarm (ALM 241)

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.

exSILentia: SIL Selection and SIL Verification (FSE 241)

Attendees will learn how to perform Safety Integrity Level (SIL) Selection and Verification using the advanced capabilities of exSILentia® . This will help users determine the required risk reduction for each hazard scenario and the achieved risk reduction for each identified Safety Instrumented Function (SIF). The class will also cover interfacing with Process Hazard Analysis (PHA) results, documentation of the Safety Requirements Specification (SRS), and operational aspects such as proof testing.
