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.

Applying ISA-18.2 Alarm Management Best Practices to Your DeltaV System

This course will show how to implement alarm management best practices in your DeltaV system through the use of tools such as Alarm Help, DeltaV Analyze, DeltaV Mosaic, Alarm Shelving, Conditional alarming, System Alarm Management, XL Reporter, and SILAlarm. It will also discuss how to make your DeltaV system comply with the ISA-18.2-2016 standard “Management of Alarm Systems for the Process Industries” by following the alarm management lifecycle. Attendees will gain an appreciation for the alarm management capabilities available in DeltaV so that they can determine how to best apply them to their operations. The course prepares participants to support an alarm management program for a DeltaV system including tasks such as creating an alarm philosophy document, performing alarm rationalization, analyzing alarm system performance, alarm system maintenance, and resolution of alarm management issues.

FSE 244 - SIL verification with SILver™

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.
