BART FPSO MODULE: AN INNOVATIVE METHODOLOGY FOR PROCESS RISK ASSESSMENT ON FLOATING OILGAS ASSETS

摘要

In the latest years O&G industry has generally recognized that Process Safety and Asset Integrity Management are key drivers for correctly managing assets and ensuring their ability to perform their functions efficiently and as intended whilst protecting people and environment for all the life-cycle. In 2009 an innovative risk screening methodology was developed for evaluating hazards and establishing priorities for risk reduction supported by a dedicated software called BART (Baseline Risk Assessment Tool). BART combines a simplified QRA for the calculation of frequency and consequences of the accidental event and the Bow-Tie methodology for the identification of the safety barriers in place. Dedicated checklists allow to evaluate the efficiency of the barriers and their contribution in reducing frequency and/or consequences of the accident. The result of the analysis is the evaluation of risks related to plant process units (e.g. separators, compressors, etc.) and the identification of recommendations for the further improvement of safety barriers in place. During the years the tool has been continuously updated with new features and additional modules with the aim of creating a comprehensive tool capable of performing quick but complete risk assessments on Oil&Gas Upstream industry assets. The latest of these update is a brand new module dedicated to Floating Production Storing and Offloading (FPSO) Units and Floating Production Units (FPU), and, in the paper, its methodology and new features are described also through the outcomes of the first real case application.
