Article
Full-text available
Complexity in marine operations requires a robust and dynamic framework for human error assessment to aid safety-based decision making under uncertainty. The current study presents a dynamic Human Factors Analysis and Classification System for Maritime Accident. The model is used for human factor assessment in critical maritime operations, consider...
Article
The growth of Arctic shipping requires effective tools to assess the appropriateness of existing practices on safety and resilience levels, especially in the enforcement of the Polar Code. Understanding such, in this study, we develop a resilience index using the Fuzzy Analytical Hierarchy Process (FAHP). Data collection for the index’s implementat...
Article
Full-text available
Global maritime piracy became an increasingly important issue amongst crew members, especially since the recent tightening of military budgets after the global financial crisis and the global shortage of ship officers. This paper reports the findings of a survey of the factors that affect the crew members’ attitude toward their job, including pirac...
Conference Paper
Full-text available
Increased number of ships in the Arctic region has created a dilemma for insurance companies. On the one hand, there is a growing market for insurance in this region. Despite this, many insurance companies are hesitant insuring ships going to the Arctic due to the limited information and knowledge. To address this, the paper presents a novel method...
Article
Full-text available
In harsh environments, offshore oil and gas support operations are subjected to frequent logistics and supply chain operational disruption, due to harsh environmental factors with their associated risks. To capture these stochastic influential factors and support related decision making, it is helpful to develop a robust and dynamic probabilistic m...
Article
As the rate of ice melt in the Arctic increases, the potential for shipping activities is also in-creasing. However, infrastructure along the northwest passage (NWP) in Canada’s Arctic isalmost nonexistent. This presents major challenges to any response efforts in the case of anatural disaster. Also, the Arctic is home to many indigenous communitie...
Article
Despite its political, regulatory, technical, and environmental challenges , the recent trend of ice melting in the Arctic region has caused the increase in international shipping activities. Accordingly, this is supported by research focusing on a wide variety of shipping issues in the Arctic. Surprisingly, this is not the case in Arctic port rese...
Article
Extreme Weather Events (EWEs) are currently not well understood by the maritime community, even though the shipping industry is not immune to their potential disastrous consequences. This is critical for the Arctic supply chains, considering the serious lack of experience, data, communication facilities, and that rules and regulations governing the...
Conference Paper
This paper presents a novel approach to assessing the cost of container liner shipping through the Northwest Passage (NWP) on northern local communities. Based on some representative communities, concerns of the residence of these Canadian Arctic regions were assessed. Two essential factors to the well-being of the community members—air pollution a...
Conference Paper
Through combining the likelihood, visibility, and consequence severity (time delay, damage to quality, and financial loss) of Extreme Weather Events (EWEs) we quantified the risks for shipping in the Arctic. This was achieved by developing a coupled Failure Mode, Effects and Criticality Analysis (FMECA) and Bayesian Belief Network (BBN) model. We i...
Article
Full-text available
This paper proposes an Object-Oriented Bayesian Network model to study oil spill mitigative measures using cost-effectiveness as a decision-making factor. The cost-effectiveness is defined as the ratio of dollar spent to the efficiency of oil removal in the spill area. The proposed model considers the complexity, lack of data, and uncertainties in...
Article
Full-text available
Oil spills resulting from maritime accidents pose a poorly understood risk to the Arctic environment. We propose a novel probabilistic method to quantitatively assess these risks. Our method accounts for spatiotemporally varying population distributions, spreading of oil, and seasonally varying species-specific exposure potential and sensitivity to...
Article
Created in 1993, the particularity of Journal of Transport Geography (JTRG) is to put ‘transport’ at center stage in human geography, long after similar initiatives about cultural, tourism, political, urban, and rural geographies. The goal of this research is to estimate JTRG's relative importance of (and interplay between) ‘transport specializatio...
Conference Paper
This paper develops the SocioEconomic Model for the Arctic (SEMA), a probabilistic graphical model based on Bayes' theory, in assessing the socioeconomic impacts of oil spills in the Arctic area. It is illustrated through a case study and scenario-based analysis. The results of the latter using SEMA is that the size of vessel and the oil type spill...
Conference Paper
Oil encapsulation and migration processes are yet to be completely understood. This is partly due to the lack of available field data, as well as the complexity of the continually changing sea ice environment. Understanding the fate of oil spills in the presence of sea ice is vital for successful oil spill recovery and risk management strategies in...
Article
Arctic shipping can be a schematic exposition on how the human race can benefit through effectively adapting the impacts posed by climate change. Indeed, the region has experienced unprecedented rate of ice melt, paving the way for shipping that may comprehensively transform transportation networks and global supply chains. However, if not managed...
Article
Full-text available
The paper explores the perceptions of port decision-makers on the effectiveness of climate adaptation actions. The findings suggest that while port decision-makers are aware of potential climate change impacts and feel that more adaptation actions should be undertaken, they are sceptical about their effectiveness and value. This is complemented by...
Conference Paper
The prospect of shipping in the Arctic poses potential oil spill risk. To minimize this risk, it requires detailed evaluation of the effectiveness of measures to be used to control and mitigate the spill. In this paper, a model is presented to study and evaluate strategies for reducing the effects of oil spills on the Arctic marine ecosystem. Risk...
Article
This paper presents a methodology for the analysis of Arctic shipping accident scenarios using Bayesian Networks (BN). The proposed methodology is applied to a scenario involving a collision between a vessel and an iceberg. The study aims to identify the most significant causative factors to the potential accident scenarios. It is achieved by under...
Article
A model that can evaluate the ecological risk posed to the Arctic marine ecosystem is presented in this paper. The proposed model is aimed at evaluating the risk of an accidental oil release. The model incorporates a release and dispersion model, fate and transport model, and ecotoxicological modelling. Uncertainties in the proposed model and data...
Conference Paper
This paper describes the essence of establishing a dynamic fugacity model, mainly in the framework of assessing the potential risk posed by oil spills during Arctic shipping. Key to evaluating this risk is the fate and transport processes as they occur in ice-covered waters. A review of relevant weathering and transport processes is therefore prese...
Article
Improved understanding of ecological risk associated with Arctic shipping would help advance effective oil spill prevention, control, and mitigation strategies. Ecological risk assessment involves analysis of a release (oil), its fate, and dispersion, and the exposure and intake of the contaminant to different receptors. Exposure analysis is a key...
Article
This paper presents a model of oil weathering and transport in sea ice. It contains a model formulation and scenario simulation to test the proposed model. The model formulation is based on state-of-the-art models for individual weathering and transport processes. The approach incorporates the dependency of weathering and transport processes on eac...
