A modelling methodology for the assessment of preventive maintenance on a compressor drive system
Zhang, Yun; Barros, Anne; Rauzy, Antoine; Lunde, Erling (Chapter, 2018)Huge rotary machines are commonly used in oil and gas processing plants for separation, compression and boosting. Their reliability is of high importance to avoid operation downtime and production loss. In this paper, we ... -
Assessment of a condition-based maintenance policy for Subsea systems: A preliminary study
Zhang, Yun; Barros, Anne Cecile Pénélope; Rauzy, Antoine (Chapter, 2017)Subsea systems are prone to degradations and failures because they are located in a harsh environment. Their performance can be improved by implementing good maintenance policies, for instance condition based maintenance ... -
Common Cause Failure Analysis - Improved Approach for Determining the Beta Value in the PDS Method
koo, kwiyeon (Master thesis, 2017)This master thesis investigates definitions and classifications of the common cause failure from various industries. From the investigation, four core aspects of the definition for the common cause failure are extracted, ... -
Condition-Based Maintenance Models: Application to Subsea Safety Systems
Zhang, Yun (Doctoral theses at NTNU;2018:375, Doctoral thesis, 2018)This PhD thesis clarifies concepts and challenges in maintenance modelling for subsea systems. The main objective is to develop suitable condition-based maintenance (CBM) models for some typical safety systems in subsea. ... -
Coupling AltaRica models with optimization heuristics for the assessment of maintenance policies
Jin, Huweiyang (Master thesis, 2018)The main objective of this thesis is do maintenance optimization for a system using AltaRica simulation tools. Maintenance optimization is based on the assessment of maintenance policy. Stochastic simulation is applied to ... -
Decision diagram algorithms to extract minimal cutsets of finite degradation models
Rauzy, Antoine; Yang, Liu (Journal article; Peer reviewed, 2019)In this article, we propose decision diagram algorithms to extract minimal cutsets of finite degradation models. Finite degradation models generalize and unify combinatorial models used to support probabilistic risk, ... -
Efficient Handling of Empirical Probability Distributions in RAMS Models
Müller, Florian Marcel Carl (Master thesis, 2017)Performing reliability assessments always relies on utilizing data. Most often, this data is provided in the form of historic failure dates. To understand this data, models are used to derive reliability characteristics ... -
Evaluation of a Scenario-Based approach to Systems Engineering
Rønning, Kristoffer Berg (Master thesis, 2019)Den økende forekomsten av kompleksitet i tekniske systemer krever godt samspill mellom de involverte interessentene. Industrielt systemdesign (systems engineering) er en tverrfaglig tilnærming til utvikling av balanserte ... -
Finite Degradation Structures: A Unified Framework of Combinatorial Models in Probabilistic Risk/Safety Assessment
Yang, Liu (Doctoral theses at NTNU;2020:127, Doctoral thesis, 2020)This PhD thesis presents a new modeling framework, called finite degradation structures (FDSs), which can be used as a unified framework of combinatorial models in probabilistic risk/safety assessment. The so-called ... -
Notes on Computational Uncertainties in Probabilistic Risk/Safety Assessment
Rauzy, Antoine (Journal article; Peer reviewed, 2018)In this article, we study computational uncertainties in probabilistic risk/safety assessment resulting from the computational complexity of calculations of risk indicators. We argue that the risk analyst faces the fundamental ...
