“Offshore directive” on major accidents: A barrier-based safety management system built on shared ontologies and taxonomies. Real applications in Italy

According to European “Offshore” Directive (2013/30/EU) by the next July, 19th safety cases (Relazioni Grandi Rischi - RGR, Major Accidents Report) should be submitted to the Authorities Having Jurisdiction (AHJ) in order to maintain the license to operate. By the preparation of RGRs the Owner should identify all the hazards connected with the installation, assess all the major risks, identify the acceptable/tolerable risks according to a defined ALARP criterion for human life and environment. Taking inspiration from real applications in Italy, this paper intends to highlight: • the importance of a coherent assessment framework based on rule sets to manage all the information gathered during the various stages (also to facilitate the assessment conducted by the AHJ and the selected independent third-party inspector); • the advantage coming from the use of a collector cloud-based IT system to manage data during assessment and to update them in the future leveraging the MOC process (also enforced as a specific requirement of the directive) across several installations and assets with a barrier-based management system.
