ABSTRACT Maritime pilots assist in manoeuvring ships arriving at or departing from a port. The most perilous part of their work is embarking and disembarking the vessel. The operational process of transferring maritime pilots is dangerous because the nature of the work involves risks such as falling from the pilot ladder into the water. Therefore, detailed risk analyses that consider potential operational failures are essential to improve pilot transfer safety. This paper presents a comprehensive risk analysis for the operational transfer processes of maritime pilots utilizing fuzzy extended fault tree analysis (FFTA). FFTA is a robust risk analysis method commonly used in the maritime industry. It is capable of predicting risk quantitatively by addressing the potential basic events of a system. In this study, the risk of encountering an accident during the transfer processes of maritime pilots is found to be 3.95E-03. The outcomes of this paper will provide valuable contributions to the safety of maritime pilots, who have suffered from substandard transfer process. The paper also highlights the failures and deficiencies with respect to operational processes in embarking/disembarking with the aim of minimizing the associated risks.

ABSTRACT Research on the spatio-temporal evolution of the port system along the 21st-century Maritime Silk Road (MSR) can reveal the development law of ports. This study adopts the Herfindahl-Hirschman index, rank-size law, and an improved spatial and temporal correlation to investigate the spatial distribution and spatio-temporal correlation characteristics of container ports along the MSR during 2000–2019. The results show that 1) the distribution trends among port clusters have significant differences, and the gravity centre of the port system gradually shifts from Europe to Asia (market shares of European and Asian ports decline from 28.15% to 19.83% and increase from 63.80% to 66.78%, respectively); 2) the port system undergoes periodic ‘decentralisation–agglomeration–decentralisation’, and its structure gradually develops a ‘spindle’ or ‘olive’ shape; 3) the initial effect of MSR arises on the economic development of ports, and the spatial occupation ability of small- and medium-sized port clusters increases steadily; and 4) the spatial and temporal correlation gradually increases. The evolution of temporal correlation is more complicated with a bifractal structure in 2000–2010. This study can provide decision support for port development and thus clarifies the investment environment and construction of MSR.

ABSTRACT We show that demand shocks have a greater effect on real freight rates compared to supply (fleet) shocks both historically and on impact. By contrast, supply shocks have a larger impact on net contracting activity when compared to demand shocks. This paper disentangles for the first time demand and supply shocks driving shipping freight markets and assesses their impact on net contracting activity, a key measure of shipping investments. In the process, we construct novel indices of demand for shipping transportation. Policy-related issues are quantified through drawing forecast scenarios for the response of real freight rates to unexpected demand and supply changes. (R41), (E32).

ABSTRACT This paper investigates a covering time minimisation problem of the maritime rescue missions that arise in practical rescue operations in the context of Hong Kong waters. In this problem, a fleet of heterogeneous vessels is deployed at marine police bases to deal with emergencies. Once an emergency rescue request is received, the marine police should send sufficient vessels to arrive at the incident site as soon as possible to provide critical medical service to the injured or the sick. A basic question to the rescue missions is that what is the minimal covering time that marine police could promise to arrive at any incident site. The shorter time the water district can be covered, the more likely lives and properties can be saved and the better the rescue service is. To address this problem, this paper formulates a mixed-integer programming model. Considering the expensive computational cost, a two-stage method is proposed. Extensive numerical experiments and a case study are performed to demonstrate the efficiency of the proposed algorithm and illustrate how our model can be applied to solve practical problems. Our study contributes to the stream of research on maritime rescue problem that is gaining increasing concern in recent years.

ABSTRACT Since 1997, researchers have increasingly studied different aspects of seafarers’ health. However, no comprehensive review of the literature has been conducted. This study maps seafarers’ health research published from 1997 to 2020. A total of 120 publications were collected for bibliometric analysis. We find that three relatively large research teams have formed, which have mainly conducted cohort studies, questionnaire surveys, and maritime field studies. The primary research hotspots are comparison of differences in occupational health; disease causes and prevention; health risk factors and their interventions; and work health and safety. Changes in research hotspots can be summarised as a shift from seafarers’ physical health to physical and mental health, and, subsequently, a shift from health to work health and safety. Future research is likely to focus on the influence mechanism of seafarers’ stress on their health; the influence mechanism of the shift-work crisis on seafarers’ health and its interventions; whether seafarers’ health affects their retention; an overall framework for seafarers’ work safety and health; and the impact of natural gas emissions on seafarers’ health as well as related interventions. The results can be used to increase the understanding of seafarers’ health research and support further work in this field.

ABSTRACT Container ports operate in more challenging and volatile environments at present times. Events such as US-China trade tensions and the COVID-19 pandemic severely affect numerous container ports at various levels. Strategies pursued by container ports are key to port development and management amidst these challenges. Drawing on configuration theory, this research employs Fuzzy-set Qualitative Comparative Analysis to investigate the relation between port strategies and container throughput. The research contributes to the literature by proposing an approach to account for complexity of the port sector and offers insights into strategies adopted by major container ports. The research further identifies 10 port strategies and proposed indicators that can represent the essence of these strategies. Being able to represent strategies in a quantitative format is important for strategy analysis and performance evaluation. Results reveal that major container ports employ a combination of strategies which address both the supply and demand-side aspects of the port business. Growing digitalization and digitization coupled with advancements in information capture, diagnostics capabilities and predictive abilities means a greater role for data analytics to influence container port strategy and performance. Implications for port managers, policy makers and researchers from the perspective of port policy and management are proposed.

ABSTRACT In compliance with the progress of the Belt and Road (B&R) initiative, there exists a notable and continuous increase in the reliance on maritime and onshore transportation. Therefore, unimpeded transportation has become China’s goal to ensure its security of trade and energy resources. This study proposes a useful framework for the quantitative assessment of key Strategic Transport Passages (STPs) to identify and rank China’s STPs in the context of the B&R. An evaluation hierarchy consisting of general criteria and sub-criteria is developed to evaluate the strategic value of alternative passages. The Evidential Reasoning method is employed to carry out the synthesis process with the Intelligent Decision System software package as it is effective when combining both qualitative and quantitative criteria of a complex nature. Finally, China’s top ten STPs and their ranking are determined by their associated strategic values. The Strait of Hormuz ranks first followed by the Strait of Malacca. Alashankou, located in the Xinjiang Uyghur Autonomous Region, China, is the only onshore passage among the top ten STPs. Though the Panama Canal is not involved with the B&R, it is still within the top ten STPs, due to its economic significance.

ABSTRACT This study firstly explores dynamic volatility spillovers across bunker fuel markets in shipping industry. Volatilities in bunker markets are measured by using the dynamic conditional correlation GARCH model. And then bunker volatility spillovers across markets are studied. Our analysis provides an evidence of unidirectional volatility spillovers within Asian (European/American) region and across regions, and also documents that Singapore bunker market is a leading market in transmitting volatility within Asian region and across regions. Furthermore, we measure time-varying volatility spillover effects among Singapore bunker market and shipping freight markets, and between Singapore bunker spot and futures market. The results reveal information transmission and could assist market participants and stakeholders to adjust hedging strategies and minimize risks according to the interrelationships across markets.

ABSTRACT The rapid development of the intermodal system has led to the intensification of the hinterland competition within the port group, and the spatial pattern of the hinterland has become discontinuous. Based on geographic information system technology, a spatial interaction model, in which the intermodal cost distance is computed by integrating the raster analysis method and network method, is developed to facilitate the examination of the spatial evolution process of the port group intermodal hinterland. Considering the example of the Gulf of Guinea port group in West Africa, the spatial evolution process of its five ports is simulated in three scenarios. The results indicate that intermodal transport drives the hinterland’s discontinuous development, and the direction and layout of the intermodal corridors significantly impact the hinterland competition of the port group. In most cases, the intermodal corridors can help realize connected ports to enhance the hinterland’s competitive advantage within the port group. However, adjacent ports may also benefit from this aspect under certain conditions, which implies the importance of port cooperation in planning collection and distribution corridors. The model and findings can theoretically support the decision-making of port investors and operators.
