Abstract
The Petro-HRA method has been developed in an R&D project called “Analysis of human actions as
barriers in major accidents in the petroleum industry, applicability of human reliability analysis methods”,
Project no. 220824/E30. Petro-HRA is a method for qualitative and quantitative assessment of human
reliability in the oil and gas industry. The method allows systematic identification, modelling and assessment
of tasks that affect major accident risk. The method is mainly intended for use within a quantitative risk
analysis (QRA) framework, but may also be used as a stand-alone analysis. Petro-HRA should be used to
estimate the likelihood of human failure events (HFEs) in post-initiating event scenarios.
