Layer of Protection Analysis Training and Certification

Learn all about Layer of Protection Analysis in this easy online LOPA Course from Abhisam and get certified as a certified LOPA Professional.

Easy learning via real life examples, videos, animations, graphics and exercises. This is not a PPT or a video of a guy speaking into the camera.

Take this easy online Layer of Protection Analysis training course from Abhisam and qualify as a LOPA Professional when you pass the associated exam.

LOPA is a well accepted technique used in Hazard and Risk Assessment. It is considered to be one of the best semi-quantitative techniques, that can give you an order of magnitude estimate of the risk potential of your plant or facility for different scenarios. Further it also aids in building Independent Protection Layers (IPLs) to reduce the initial risk to a tolerable value.

Customer Feedback

“I have worked in the International Oil and Gas Industry as a technical instructor for more than thirty years. I have both used and recommended the products of Abhisam. I recommend them highly to all engineers and technicians in our industry. No praise is too great!!
John Longden
GCGI LCGI. Senior Trainer
Petroleum Training Institute, UK

“I work as an independent HSE consultant. I have attended several training courses on PHA, Process Safety and LOPA by various training providers in the past. However this Abhisam LOPA course is by far the best one that I took. It is self-paced and easily accessible. The structure and flow of the course makes this complex  subject, interesting and  easy to understand. I would recommend this course to anybody who wants to learn  LOPA.

  • Thank You

The Self Assessment test has several questions, based on the concepts learned in the course. This enables you to know how well you have understood LOPA. It also helps as mock test to prepare you for the LOPA Certification Exam, which you can take to earn your Certificate and Badge.

Why is LOPA important?

What’s the problem?

The Layer of Protection Analysis method (LOPA) is one of the best semi-quantitative Hazard and Risk analysis methods available.

Although used extensively in industry, there are very few formal training programs out there on LOPA, that are easily understood by any engineer or safety professional. Many of the books available are not very reader friendly. If you do an instructor led course on LOPA (either in a physical classroom or online) you are likely to get bored quickly and forget whatever you learned in the next few days after the training.

This is not a good situation at all!

So what did Abhisam do?

Abhisam made the entire subject very interesting by making it a self-paced course (learn on your own schedule), using animations and simulations to depict actual process plant situations, using the example of a hypothetical company called ABC Industries and following their LOPA sessions via simulated videos. This makes you feel as you are observing a LOPA session in person, to get you a feel of how things are in real life.

Not only this the Abhisam course is very comprehensive, consisting of twelve learning modules and a self-assessment test.

This Abhisam course makes understanding the LOPA technique very easy.

What’s the root cause of so many accidents in the Process Industry?

Many of the process industry accidents and disasters can be traced to a lack of awareness and training. Taking this course enables you to become a LOPA Professional and start working towards making the process industry safer.

Can I not get this information free from elsewhere?

There is a myth  “Just Google it”

Unfortunately it is not true. If you Google for it you are likely to get a large number of LOPA related books,  pdf documents, presentations, articles and other material. It will take you a long time to go through it and at the end of the day you may

a) Not be able to string it all together-most information on the internet is in bits and pieces (although large ones). It is not put out there as a logical construct or in any sequential manner. This is to be expected since it is all from different sources who may have different interests.

b) Be more confused than what you were before you started searching for it

c) You may not be sure that whatever information you get is current (updated) and authentic.

d) You will not be getting any certificate for your efforts.

Plus you will spend several hours of your time doing all this for zero returns on your investment!

On the other hand, when you take this Abhisam LOPA training course, you know that

a) It is very carefully made, with subject matter experts in the field of Layer of Protection Analysis

b) Utilizes animations and simulations to help you understand concepts real quick. These are not available anywhere else.

c) Get access to a real life Case Study, that clearly shows you how to carry out a LOPA for an actual facility.

d) Earn a Certificate when you pass the associated exam and also get an electronic badge that can be displayed online on places such as LinkedIn. Get Noticed as an Expert!

Can I not simply buy a book? That will be much cheaper!

Of course, you could always pass this up and decide to go for  buy a book on this topic,


remember that there are some disadvantages with this approach

a)  The first is that not a single book is available on the market, that covers all the topics that you need to know. On the other hand, there are a lot of things in every book, that you can safely skip, without missing anything.

b) Watching an animated simulation makes you grasp a concept much faster than merely reading about it. (A picture is worth a thousand words and an animation is worth a thousand pictures)

c) Nobody gives you a certificate if you simply read a book.

What does the $7 trial include?

The $7 trial includes trial access to ALL the courses in the Abhisam Catalog for a limited time.

You can access the course for a period of one year, within which you need to take the exam to earn a Certificate (electronic). You will also earn an electronic badge that can be displayed online on LinkedIn and similar portals.

What is the Abhisam GOLD membership?

When you subscribe to the Abhisam GOLD membership, you get access to all the courses in the Abhisam Catalog, by paying just one low monthly subscription. You can also get a free certification exam every month. If you are interested in taking a bunch of courses, then the GOLD membership gives you an affordable plan to do this. This is available to individuals only.

What is the Abhisam Platinum membership?

This is meant for organizations with multiple learners. When you subscribe to the Abhisam Platinum membership, your learners get access to all the courses in the Abhisam Catalog, by paying just one low Enterprise yearly subscription. You can also get a free certification exam every month.  Additionally you also get a Dashboard where your Training Manager can see the progress of the learners, such as learner module completion, login times, test scores, etc.
