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.

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.

Generating logic using the DeltaV SIS Configurator

Generating logic using the DeltaV SIS Configurator, FSE 246, explains how the exSILentia DeltaV SIS Configurator plug-in is used to generate logic for a DeltaV SIS system. Students will learn how to generate logic for their DeltaV SIS logic solver using their conceptual SIF design information from the SILver™ and the Design SRS modules. This course will review how selections made in exSILentia will impact the logic creation process. It will also provide instruction on generating a cause and effect matrix representing the logic.

Layer of Protection Analysis with LOPAx™ and Safety Requirements Specification with SRS

Layer of Protection Analysis with LOPAx™ and Safety Requirements Specification with SRS, FSE 243, explains how the exSILentia LOPAx™ module is used to conduct a Layer of Protection Analysis and how SIF requirements can be documented using the exSILentia SRS module. 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™ and SRS. 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). Users will learn how to record mandatory functional and integrity requirements for each SIF. It will teach users how to transfer data from PHAx™ to LOPAx™ as well as from LOPAx™ to SRS.

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.

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.
