It is proved that most of industrial accidents are related to some kind of human failure, sometimes with catastrophic consequences. The estimation of human error is a contributory factor for many industrial accident occurrences.
The present paper refers to human error probability in industrial activities. The paper intends to make a literature revision referring important concepts about human behavior and human reliability. It is fundamental to
identify tasks, actions or activities that depend on human behavior or even determine the conditions that influence human error and thus increasing risk. With this target, the most important methods, techniques and tools
to assess human failure (error) are referred showing their potential applicability. Secondly, the paper proposes the approach that gives an insight on training quality, with a dedicated focus on virtual reality training,
based on which suitable corrective measure can be adopted to decrease human error. Pioneering organizations are using Virtual Reality (VR) to improve productivity and quality of the operations. By combining the strengths
of humans and machines, VR will dramatically increase value creation for the organization. The effectiveness of the VR-based training process depends directly on the quality of the prepared training material and on the
quality of the prepared virtual training environment, which directly improves learning curve of the trainee. Virtual training is a promising solution to bypass the limitations of hardware training and especially to test
and secure production processes in a safe environment. O&G has remarkable interest in applying VR/AR techniques in training, maintenance, operation.
