RISA Generalized Framework for Risk-Based Extreme Load Analysis in Offshore System Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The primary aim of this research is to consider the correlation among environmental factors in calculating 100 and 1000 years of extreme load design criteria. This is done by considering load as energy transferred from ...
Layout Optimization of a Floating Liquefied Natural Gas Facility Using Inherent Safety Principles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a layout optimization methodology for the topside deck of a floating liquefied natural gas facility (FLNG) using inherent safety principles. Natural gas is emerging as a clean energy, and a large amount ...
A Numerical and Experimental Study of Kick Dynamics at Downhole
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The early detection of a kick and mitigation with appropriate well control actions can minimize the risk of a blowout. This paper proposes a downhole monitoring system, and presents a dynamic numerical simulation of a ...
Probabilistic Modeling of Pitting Corrosion in Insulated Components Operating in Offshore Facilities
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pitting corrosion under insulation is one of the challenging issues for safe operation of offshore facilities. Degradation usually remains hidden causing the inspection of insulated assets to be equally challenging. The ...
Probabilistic Methods for Predicting the Remaining Life of Offshore Pipelines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When offshore pipelines approach the end of their design life, their condition could threaten oil flow continuity as well as become a potential safety or environmental hazard. Hence, there is a need to assess the remaining ...
Probabilistic Performance Assessment of Fiber Optic Leak Detection Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Leak detection systems (LDSs) play a major role in enhancing reliability and operability of oil and gas pipelines. They have the functional capabilities to detect, locate, and quantify leaks before they can cause devastating ...
Pitting Degradation Modeling of Ocean Steel Structures Using Bayesian Network
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modeling depth of long-term pitting corrosion is of interest for engineers in predicting the structural longevity of ocean infrastructures. Conventional models demonstrate poor quality in predicting the long-term pitting ...
Using Simulator Data to Facilitate Human Reliability Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Data scarcity has always been a significant challenge in the domain of human reliability analysis (HRA). The advancement of simulation technologies provides opportunities to collect human performance data that can facilitate ...
Predictive Abnormal Events Analysis Using Continuous Bayesian Network
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The reliable prediction and diagnosis of abnormal events provide much needed guidance for risk management. The traditional Bayesian network (traditional BN) has been used to dynamically predict and diagnose abnormal events. ...
Rare Event Analysis Considering Data and Model Uncertainty
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In risk analysis of rare events, there is a need to adopt data from different sources with varying levels of detail (e.g., local, regional, categorical data). Therefore, it is very important to identify, understand, and ...
