Framework for the assessment of the safety culture in the oil and gas industry.

Approaches to safety culture assessment may have many limits if supported exclusively by quantitative methods. Based on this, a research team developed a quantitative-qualitative approach to assess the maturity of the safety culture on an oil platform. To that end, the team sought to develop and test a method consisting of an initial ethnographic phase followed by four other distinct phases: definition of homogeneous groups; production of customized questionnaires; quantitative evaluation; and qualitative assessment. The results show the emergence of trends, from pre-defined themes in safety culture to specific levels of maturity for each of the homogeneous groups. At the same time, it was perceived that the maturity level of the groups is defined from the daily work practices developed by each one of them. This experience allowed us to propose a framework for assessing the maturity levels of safety culture for the oil and gas industry.
