Human reliability analysis (HRA) is the most acknowledged methodology to assess the probability of human errors depending on the tasks and its contextual factors. There are many methods available, but some exploratory research show that only a few of them are frequently cited in research papers, or even accepted by safety regulators.

This paper describes the methodology used to do the systematic review approach to understand which HRA techniques are the most cited by country and by industry sector along the years. The research methodology has considered only research papers. The results per country focus only on the oil & gas industry sector, more specifically on the countries with safety regulators which are part of the International Offshore Forum (IRF): Australia, Brazil, Canada, Denmark, Ireland, Mexico, The Netherlands, New Zealand, Norway, United Kingdom, and United States of America.

Future development of this review is to also review regulations and consultancy companies' portfolios. The aim is to understand in which level the industrial practice follows the pattern observed in academia and if they are influenced by regulations.
