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.

Estimation of Water Infiltration at a Given Embankment Dam with Sealing Deficiencies by a 3D Numerical Model
The paper presents a way of studying the water infiltration at the Motru embankment Dam (river ballast fill, clay core sealing) by a 3D numerical model covering the deficient right supporting bank. Since due to sealing i...
Studying Transients in Water Supply Systems
Transient operating states occur in water supply systems under pressure. Transient operating states place such extreme loads on the pipes that they might cause burst water pipes, so to be able to avoid damages and operat...
Statistical Analysis of the Pollution of a Hydraulic Oil Based on the Evolution of the Filter Clogging on the Pressure Pipe
We present in this paper the results of an experimental study conducted on the analysis of the influence of clogging of a hydraulic filter, installed on the discharge pipe of a variable displacement pump, the operating p...
Analysis of Intelligent Control and Interface in Pressurized Liquid Injection Systems for Competitive Technical Solutions
