A FEW LEARNER TESTIMONIALS

I have worked in the International Oil and Gas Industry as a technical instructor for more than thirty years. Most of my work has been with those whose first language is not necessarily English; hence “understanding” can be a problem!

I have both used and recommended the products of Abhisam (Safety Instrumented Systems, Hazardous Area Instrumentation, Fieldbus, Gas Monitors e-learning courses and both the ebooks-The Practical Guide to Hazardous Area Classification and the Quick Guide to AC Variable Frequency Drives), as excellent training support aids. My field of work has been in the areas of instrumentation and automation. The materials are presented in a very professional manner being clear, concise and very easy to understand.
I recommend them highly to all engineers and technicians in our industry. It is my intention to increase my library of Abhisam training materials and to use them not only to enhance my own fields of work but to hopefully increase Abhisam sales! They are excellent and I recommend them highly. No praise is too great!!

I am working in one of the world’s leading EPC companies, engaged in the Oil & Gas industry. I have purchased the Safety Instrumented Systems, Hazardous Area Instrumentation e-learning courses and the ebook Practical Guide to Hazardous Area Classification. All of them are excellently crafted, the best available online, with excellent support via email.
I appreciate the good work done by Abhisam and hope that they do come out on more such courses, especially on Control Valves.

Course Background

Safety Instrumented Systems refer to that class of automation and control systems that are used to ensure safe shutdown or other safe means of carrying out actions to prevent dangerous occurrences in a plant or machinery. These systems protect assets, humans and the environment and are used across a wide variety of industries. Thus you will find these SIS safety instrumented systems, in oil and gas installations, chemical plants, power plants, food and beverage industries, automobiles, trains, planes and even lifts. You will also find them used for machinery applications such as gas turbines, metal presses, lathes and similar kinds of factory equipment.

This course will cover the systems used in process plants. There are commonly used international standards for functional safety and safety instrumented systems such as IEC 61508 and IEC 61511. This course will cover both, although it is more focused on IEC 61511 (the standard used in the process industry). SIS Safety is an important part of Process Safety Management and a well designed and maintained SIS system will help in drastic reduction of operational risk associated with manufacturing and process plants. Thus it is an important part of Enterprise Risk Management.

The course will cover the entire spectrum of everything related to Functional Safety and SIS including but not limited to hazard and risk assessment fundamentals, techniques such as lopa,  sis concept,  safety instrumented functions, failures and reliability, safety integrity level (SIL), including how to carry out a SIL study, designing safety loops, different architectures, sil verification calculations, concepts from iec 61508 and iec 61511 standards, sis hardware, proof testing, maintenance and more.
