A Bayesian approach to risk modeling of autonomous subsea intervention operations
(Journal article; Peer reviewed, 2018)The introduction of autonomy in subsea operations may affect operational risk related to Inspection, Maintenance, and Repair (IMR). This article proposes a Bayesian Belief Network (BBN) to model the risk affecting autonomous ... -
A multi-sensor fusion framework for improving situational awareness in demanding maritime training
(Journal article, 2017)Real offshore operational scenarios can involve a considerable amount of risk. Sophisticated training programmes involving specially designed simulator environments constitute a promising approach for improving an individual's ... -
Availability-based engineering resilience metric and its corresponding evaluation methodology
(Journal article; Peer reviewed, 2018)Several resilience metrics have been proposed for engineering systems (e.g., mechanical engineering, civil engineering, critical infrastructure, etc.); however, they are different from one another. Their difference is ... -
Balancing Safety I and Safety II: Learning to Manage Performance Variability at Sea Using Simulator-Based Training
(Peer reviewed; Journal article, 2019)The article explores how simulator-based training of professional maritime deck officers can improve the management of performance variability and safety during critical operations at sea. The research has a qualitative ... -
A Bayesian network risk model for predicting ship besetting in ice during convoy operations along the Northern Sea Route
(Journal article; Peer reviewed, 2022)To facilitate shipping in ice and to meet the increasing requirements of icebreaker services, convoy operations are the most effective alternative. However, convoy operations are among the most dangerous operations as they ... -
Bayesian regression based condition monitoring approach for effective reliability prediction of random processes in autonomous energy supply operation
(Journal article; Peer reviewed, 2020)The probabilistic analysis on condition monitoring data has been widely established through the energy supply process to specify the optimum risk remediation program. In such studies, the fluctuations and uncertainties of ... -
Collision hazard modeling and analysis in a multi-mobile robots system transportation task with STPA and SPN
(Peer reviewed; Journal article, 2023) -
A Comparative Study of STPA-Extension and the UFoI-E Method for Safety and Security Co-analysis
(Peer reviewed; Journal article, 2021)Emerging challenges in cyber-physical systems (CPSs) have been encouraging the development of safety and security co-analysis methods. These methods aim at mitigating the new risks associated with the convergence of ... -
Complex accident scenarios modelled and analysed by Stochastic Petri Nets
(Journal article; Peer reviewed, 2015)This paper is focused on the usage of Petri nets for an effective modelling and simulation of complicated accident scenarios, where an order of events can vary and some events may occur anywhere in an event chain. These ... -
Criteria for qualitative methods in human reliability analysis
(Journal article; Peer reviewed, 2018)The qualitative analysis steps in Human Reliability Analysis (HRA) have received little attention in the HRA methods and in the general literature on HRA. The purpose of this paper is to investigate which quality criteria ... -
Data driven approach to risk management and decision support for dynamic positioning systems
(Peer reviewed; Journal article, 2020)Offshore oil and gas operations are inherently associated with risk and may have catastrophic consequences to life, property, and environment. Risk management is thus performed during the design, planning, and operation ... -
Deriving Verification Objectives and Scenarios for Maritime Systems Using the Systems-Theoretic Process Analysis
(Journal article; Peer reviewed, 2018)The process applied for verification of maritime systems lacks the ability to properly examine complex networks of interconnections. Verification is mainly focused on single failures of components, not properly accounting ... -
Development and testing of a risk-based control system for autonomous ships
(Journal article; Peer reviewed, 2023)This paper presents a method for designing and verifying a control system with risk-based decision-making capabilities to improve its intelligence and enhance the safe operation of autonomous systems. The decision-making ... -
Dynamic risk assessment in healthcare based on Bayesian approach
(Journal article; Peer reviewed, 2019)Risks related with healthcare are always dynamic, and they are affected by situations of patients, human errors in treatment and even the states of medical devices. This paper proposes a dynamic medical risk assessment ... -
Effect of environmental modelling and inspection strategy on the optimal design of floating wind turbines
(Peer reviewed; Journal article, 2021)In order to reduce design conservatism and consequently the cost of energy, appropriate and cost-optimal safety factors should be derived, in light of environmental load uncertainties and lifetime costs. In the present ... -
Evaluating the generalizability and transferability of water distribution deterioration models
(Journal article; Peer reviewed, 2024)Small utilities often lack the required amount of data to train machine learning-based models to predict pipe failures, and hence are unable to harness the possibilities and predictive power of machine learning. This study ... -
Fatigue reliability assessment of offshore wind turbines with stochastic availability
(Journal article; Peer reviewed, 2019)In this paper, the impact on lifetime estimation of an offshore wind turbine by introducing a stochastic model for the availability is investigated. Offshore bottom-fixed wind turbines typically have an average downtime ... -
Fragility of transport assets exposed to multiple hazards: State-of-the-art review toward infrastructural resilience
(Journal article; Peer reviewed, 2019)Vulnerability is a fundamental component of risk and its understanding is important for characterising the reliability of infrastructure assets and systems and for mitigating risks. The vulnerability analysis of infrastructure ... -
Group maintenance optimization of subsea Xmas trees with stochastic dependency
(Peer reviewed; Journal article, 2021)Subsea Xmas trees (XTs) are vital equipment for offshore oil and gas development. Due to a long and continuous operation, components of XTs often become vulnerable subjected to degradation and unexpected failures. Due to ... -
