Fault Tree Analysis Used in Offshore Industry
Journal Title: HIDRAULICA - Year 2018, Vol 0, Issue 1
Abstract
Fault Tree Analysis is one of the engineering tools that provide a systematic and descriptive approach to the identification of systems under risk. Probabilistic Risk Assessment (PRA) is a method to determine the reliability of a system based on the probability of component(s) and/or system(s) failure. Fault Tree Analysis (FTA), which is a part of PRA, provides a method for determining how failures can occur both quantitatively and qualitatively. In this paper we present the FTA for offshore facility: safety flow chart of offshore production facility, fault tree diagrams for different levels (upper level, intermediate state, overpressure, underpressure, excess temperature, ignition, excess fuel). Also, FTA for subsea control systems is presented in this paper. In conclusions, reliability analysis of the surface facilities shows that mechanical components, pumps and compressors, have higher failure rates compared to other mechanical components.
