Companies of any magnitude and category are susceptible to internal and external elements that directly influence your performance management system. The present work aims to present a methodology for prioritization of non-conformities related to audits of the main Brazilian legislation, such as ANP43, Ministry of labor, ANVISA, CNEN and IBAMA, inside the offshore industry. The methodology developed will be a key tool to management system because with the application of it the companies will make decisions about implementation of corrective actions, depending on the risk classification of the non-conformity. The prioritization methodology will be made by crossing data from a HSE matrix severity, an index of criticality and an order of magnitude according to the percentage distribution of non-conformities found in the audit of ANP43.
