HAZOP | E-Learning Course | Certification

Easy learning on HAZOP (Hazard and Operability Study) with Certificate of Competency

Hazard and Operability Study, is a well known hazard analysis tool used for risk assessment and mitigation. It is considered an important part of process safety management and HSE risk assessment of plants and facilities. It is a highly structured and systematic method, to identify all hazards in a process, evaluate the design intention, work out possible deviations & then think of mitigating those which could cause bad consequences. The deviations also include human factors, including non malicious as well as malicious intent.

Abhisam first developed this  easy online e-learning course more than 8 years ago and it has become popular all over the world, with hundreds of professionals taking it and getting certified every year. It is a highly engaging course, with Interactive Animations & Simulations, "why-we-do-it and how-to-do-it" training course. It is NOT just a video of a boring guy speaking in front of a whitebaord OR a simple powerpoint presentation!

Customer Testimonial

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. My field of work has been in the areas of instrumentation and automation, including safety related systems.  The courses 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.  They are excellent and I recommend them highly. No praise is too great!!
