Abstract

The increasing public awareness about high risks associated with chemical and petrochemical installations determined a growing attention on the improvement of protective and preventing measures. To ensure higher levels of safety, designers and operators have focused their efforts to find innovative solutions combining safety and costs for safety. It has become crucial to manage risk through the use of best practices for inspection and maintenance planning. In order to achieve this aim, a useful tool, named “Inspection Manager”, has recently been developed by ANTEA. It includes all functionalities for a easier data management concerning plant’s inspection, furthermore the implementation of methods for the quantification of managerial and organizational factors gives it additional potentialities. This work has been focused on the comparison of two approaches for the quantification of organizational and managerial factors on the frequency of release from piping to be used to support risk-based decisions by means of the use of the “Inspection Manager” tool. In this paper a comparison between two approaches for the quantification of organizational and managerial factors on the frequency of release from piping has been illustrated. To compare results the implemented “Inspection Manager” tool of ANTEA has been used and the results have been shown on a risk matrix. The inclusion of the RBI approach within the software of ANTEA (as a result of a collaboration between the University of Padova and the ANTEA Company) allows elaborating the frequencies of leakage taking into account the complexity of the system (by means of a damage factor) and the history of the equipment (maintenance, welding, etc.). The final frequencies can be modified including the influence of the managerial efficiency. The analysis of a case of piping’s breakage showed that the RBI approach is more conservative in quantifying managerial efficiency because the factor used for its quantification is defined using generic literature data, anyway in the worldwide context this approach is the most diffused. The method of Milazzo et al. (2010) modifies literature data through an audit of the management system, taking into account also of plant specificities. In this framework, the implementation of the procedure RBI in the Inspection Manager software provided a useful tool to be used to support risk-based decisions by means also of the integration of different approaches.
