The main objective of this course is to transfer to participants the theoretical and practical skills required in process plant projects for the assignment and verification of the level of SIL integrity achieved in the design of SIS, providing through the course the fundamental knowledge necessary to perform a SIL assignment and verification study in accordance with the requirements of the clauses of the IEC 61511 Part 1:2016 standard.

Performing a random hardware failure assessment (commonly known as SIL verification) on a safety instrumented function (SIF) is a key requirement specified in the international standards IEC 61508 and IEC 61511. This requirement ensures that the SIF meets the required target SIL in terms of probability of failure on demand (PFD) or probability of failure per hour (PFH) as identified in the SIL allocation study.

The course is taught in three days with classes of 4 hours each day, covering the theoretical aspects of functional safety that apply to the assignment and verification of the target SIL, complemented by practical examples.

• Understand the dangers and risks of combustion.
• Understanding the Primary Causes of Boiler and Furnace Explosions

Who is this course for:

The course is aimed at those who have responsibilities within the scope of the IEC 61511 standard. In particular:

• Process plant managers who have responsibility for the management of functional safety involving Safety Instrumented Systems.
• Control and instrumentation engineers, chemical engineers, mechanical engineers, electrical engineers who have responsibility for or have participated in exercises for the determination of SIL, specification, design, operation and maintenance of plant protection that use safety instrumented systems.
• Engineers who are responsible for performing or reviewing reliability calculations
• Safety instrumented system integrators designed to meet the requirements of IEC 61511

Requirements to attend this course:

Knowledge of the operation of Boilers and/or Furnaces. Basic knowledge of Instrumentation and Control and Basic Process Control Systems. Have completed a training course in Functional Safety – Safety Instrumented Systems or equivalent.

Prior knowledge

Previous knowledge of Safety Instrumented Systems is required to attend the course, accredited by certificates of attendance at Functional Safety of Processes courses.

It doesn’t matter if you’ve never completed a check in your professional life or if you’re already an experienced checker. This workshop will give you the knowledge you need to properly perform and document these two important tasks. The theory will be explained, and practical examples will be seen. Then, attendees will be able to apply what they have learned through the exercises that are proposed to solve both in class and outside of class.

Certificates

• Certificate of attendance accrediting the key topics covered in the course.
• Attendees who wish to do so can take an exam for the certification of the knowledge acquired.

Study Material:

Complete course notebook containing industry examples and solutions for all SIL design and verification workshops.

Recognitions:

All participants who meet the course requirements and successfully pass the final exam with a good grade will be awarded a Digital Badge. The digital Badge certifies that the participant has attended the PS11 training course and has completed the final evaluation test with a good score, verifying that said participant has assimilated the new knowledge.
