Maximizing Risk Reduction through Collection and Analysis of Operation & Maintenance Data
SILstat™ is exida’s Operation & Maintenance Data Collection tool. It simplifies the recording of safety critical events during your lifecycle processes, helping validate assumptions made during analysis and design of the SIS. SILstat™ allows you to be compliant with requirements outlined by the IEC 61511 / ISA 61511 standards and with an OSHA Process Safety Management (PSM) Mechanical Technical Program.
Learn MoreOur 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.

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
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
SIL verification with SILver™, 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.
