US port throughput of radioactive materials: a twenty-year study

This study documents that more than a half million tons of radioactive and associated materials, including wastes, were handled at US ports between 1965 and 1984. Although some ports were dominant, radioactive traffic flowed through a large number of ports. An analysis of concordance demonstrates agreement in port rankings over the 20-year period. Large, medium and small ports are identified via a cluster analysis.     

Fuzzy empty containers excess estimation as an economic indicator—the case of the north Adriatic port system

Today, approximately 90% of the world’s cargo is moved by ships and almost all general cargoes are transported in containers. Worldwide container traffic has increased over the last 20 years by 7% annually, and containerization has begun to seriously impact global trade patterns. As a result, container terminals have become very important nodes in the world’s supply chain. In this article, we have highlighted the link between the total and empty container traffic and the global economy. By way of example, we have analysed the empty container traffic in north Adriatic ports in the years before and during the global economic crisis and in a period of stability after the major economic slump. We used a fuzzy multicriteria algorithm to find out how the global crisis, which has affected ports, influences the number of excess empty containers at the terminals. We show that these factors, in particular the change of the global financial and economic situation, have different repercussions to the ports of the north Adriatic: less serious effects upon the ports that are well connected locally and substantial consequences for the ports that are well connected globally.     

Dynamics of change in the port system of the western Mediterranean

The ports of Mediterranean basin have experienced significant growth in container traffic over the last decade. In the western Mediterranean two distinct types of port have emerged: the established ports of the northern part of the basin which serve a gateway function and a set of new ports in the south which act as transhipment hubs. In this paper we explore the dynamics of change and reveal how growth is driven by shifts in individual trades. While the hub ports are integrated into Asian pendulum services, the gateway ports are experiencing growth because of new direct services to Asia and North America. We suggest that the distinctions between the transhipment hubs and the gateway ports are becoming blurred, especially because the gateway ports are also assuming greater transhipment roles. We also explore whether this new dynamism in the Mediterranean ports is reversing the long-standing hinterland domination of the ports of the northern range. We demonstrate that the gateway ports of the western Mediterranean continue to serve local and regional markets, with very limited penetration north of the Alps and Pyrenees. This is due in part to difficulties with rail services but also because of the continued efficiency of the northern range ports and their hinterland connections. We suggest that in the short run, at least, little change is likely.     

Characteristics and consequences of the cruise traffic seasonality on ports: the Spanish Mediterranean case

Cruise traffic is a maritime business and tourist typology that has expanded significantly in the past two decades. The seasonality of the industry affects maritime traffic, generating negative effects for the primary stakeholders involved in the configuration of a cruise itinerary. This article focuses on cruise traffic seasonality from the perspective of cruise ports by analysing a sample of 13 ports on the Spanish Mediterranean coast. The variable used was cruise passenger movements during the period 2000–2015. The main objective of this article is to analyse cruise traffic seasonality in order to identify a pattern, classify through a cluster analysis, and identify the changes in seasonality during the period. Specifically, a threefold analysis has been performed, with the additional goal of providing a series of counter-seasonal suggestions and strategies to apply in the management of cruise ports. First, the seasonality pattern of each port was determined. Second, a cluster analysis was conducted to classify ports into clusters with homogeneous seasonality patterns. Third, an analysis was conducted to identify the changes in seasonality during the period of analysis using the coefficient of variation and the Gini coefficient. This article concludes the existence of two port clusters with different seasonal patterns.     

The role for rail in port-based container freight flows in Britain

As supply chains become increasingly global and companies seek greater efficiencies, the importance of good, reliable land-based transport linkages to/from ports increases. This poses particular problems for the UK, with its high dependency on imported goods and congested ports and inland routes. It is conservatively estimated that container volumes through British ports will double over the next 20 years, adding to the existing problems. This paper investigates the potential for rail to become better integrated into port-based container flows, so as to increase its share of this market and contribute to a more sustainable mode split. It identifies the trends in container traffic through UK ports, establishes the role of rail within this market, and assesses the opportunities and threats facing rail in the future. The analysis combines published statistics and other information relating to container traffic and original research on the nature of the rail freight market, examining recent trends and future prospects. The paper concludes that this is an important market for rail, with considerable growth potential but to realize this it is important that a number of constraints are overcome, otherwise the long-term prospects for this rail market will be compromised.

The mid-Atlantic load centre: Baltimore or Hampton Roads?

Competition between closely situated seaports in not new. The ports of Baltimore and Hampton Roads, located at either end of Cheaspeake Bay, have been locked in a fierece battle to gain dominance in the lucrtice mid-Atlantic container traffic for a number of years. The probability that ech will succeed is not great, as shipping lines, concerned with the high costs associated with idle port time, will select one,rther thatn serve both. Indeed, evidence is beginning to mount that, dispite massive expenditures by the Stte or Maryland, the Virginia ports a reemerging as the region' load centre. This paper examines recent trends in container movements through these two major ports and suggests the long-termprospects for each. among measures considered are the location of eachi in relation to other ports both North and South, sizes of the port cities and their immediately adjacent hinterlands, proximity to inland population centres (markets), connectivity between the ports and these inland centres (by both rail and truck), expenditures by port agencies and land crries, labour relations, and availabillity of space for expansion.     

Causality between performance and traffic: an investigation with Indian ports

This paper attempts to find out the causal relationship between port performance and port traffic by using Indian data. The use of cointegration analysis has come out with the result that performance precedes traffic in most of the ports of India. Hence, government policy towards performance augmenting facilities should be given priority so that higher efficiency induces higher traffic

Next generation mega container ports: implications of traffic composition on sea space demand

ABSTRACT

Demand for sea space brought about by increasing container-shipping traffic has important implications on how this space is managed and used. This is particularly important given the long-term nature, high-asset specificity, high- opportunity cost of investment, and significant economic impact of container port activity on a locality. The challenge is especially pressing for ports, which are facing constraints in seaside capacity where container traffic also has to co-exist with the needs of other types of ship traffic. This challenge is likely be multiplied for next generation container ports, which are expected to handle even larger traffic volumes. These ports are also likely to face competing sea space demands from other economic and social activities especially when they are concurrently major confluences of trade, logistics, and urban populations. This is the first research to investigate in detail the impact and importance of investigating sea space requirements from the perspective of cargo traffic composition and ship capacity. Results show that transshipment containers can generate much higher demand for sea space due to the higher volume of shipping capacity that accompanies such traffic. Sustainability issues and managerial and policy implications pertaining to the development of next generation container ports are provided.     

Cruise Traffic Seasonality Patterns in the Western Mediterranean and the Adriatic Sea: A Challenge to Port Operators

The positive trend in the cruise industry since the beginning of the twenty-first century brings with it a series of challenges, mainly for cruise lines and ports. Among them is the seasonality of cruise traffic. This study examines the seasonality of the cruise traffic in the Western Mediterranean and the Adriatic Sea. A sample of 26 ports in 7 countries forms the basis of the empirical analysis, which uses the monthly total cruise passenger movements of each port during the period from 2005 to 2015 as a variable. Methodologically, a “dynamic” classification of ports structured in three sizes is proposed, the seasonality pattern of each port is determined, a cluster analysis is applied to group the ports in clusters with homogeneous patterns, and the changes in seasonal concentration during the analysis period are determined using a Gini coefficient. The main findings suggest the heterogeneity of the ports in the analyzed area and the existence of two clusters with different seasonality patterns. Furthermore, a list of strategies is provided to address the negative effects of cruise traffic seasonality in the management of cruise terminals, taking into account that each cluster obtained requires different strategies.     

The Caribbean basin: adjusting to global trends in containerization

Positioned strategically between major east–west and north–south trading routes, the Caribbean basin has become a locus of new service configurations in container shipping. Over the last decade global shipping lines have been restructuring their service networks in the region in order to integrate local services with the newly rationalized intercontinental connections. By comparing service network structures in 1994 and 2002 at three levels of organization—local, regional and global—we are able to show that although Caribbean ports are well connected to the global system, and while the total number of services has declined between the two years, those mounted by members of global alliances have increased. Moreover, services of the global carriers at the local and regional levels are on the increase. As much as the alliances are reshaping Caribbean networks, the smaller carriers are still playing a role, but at a reduced spatial scale. Parallel with the modifications to network configurations are the changes in the port system. Essentially, traffic of the most important ports in the north and western part of the basin has grown at slower rates than the ports in the south and east. These traffic changes are only partly related to network changes. It is the growth of transshipments that is driving the most important developments in port traffic and bringing to the forefront the development of hub ports. The most important are: Colon, Panama (southwest), Freeport, Bahamas (north), Port of Spain, Trinidad and Tobago (southeast), Kingston, Jamaica and Rio Haina, Dominican Republic (middle), and Cartagena, Colombia and Puerto Cabello, Venezuela (south).

The MED rule: the interdependence of container throughput and transhipment volumes in the Mediterranean ports

The aim of the present paper is to explain the Mediterranean Transhipment Rule by a mathematical model showing the relationship between the diversion distance and the transhipment volumes, as well as the relationship to the total container traffic volume. Thus, the formula was applied to the figures achieved in 1994, 1995 and 1996. To conform with 1994, 1995 and 1996 data the formula was slightly altered so as to forecast transhipment volumes in the Mediterranean ports. By applying the formula to the figures achieved by some Mediterranean ports, the estimations were done which describe reliably enough that the transhipment volumes depend on the diversion distance and the total traffic throughput. In short, the volume of cargo transhipped in a single port is an inverse linear function of the distance of the port from the main-line vessels' route transiting the Mediterranean, and a linear function of the port container traffic volumes.

The size effect of a port on the container handling efficiency level and market share in internation transshipment flow

This study examines the relationship between the size of a port, its efficiency increase and the performance growth in the transshipment market. The hypothesis tested is that the bigger size of a port would increase the market share of the port in container transshipment; only when the size effect guarantees better ‘relative’ container handling efficiency in competing port system where the port belongs. To verify the hypothesis, this study carries out two analyses. First, the overall efficiency change of major Asian ports is examined through stochastic frontier analysis (SFA)—this produces the relative efficiency indices of the ports. Second, the relationship between efficiency indices and container transshipment volumes is studied through panel data analysis. From these analyses, it is observed that larger Asian ports show better cargo handling efficiency in relative terms; they also record bigger market share in container transshipment, while the size effect of the ports starts to play a factor when the annual container throughput reaches 5 million twenty-foot equivalent units (TEU).

The privatization of Polish ports—the present situation and outlook for the future

The Polish economy is going through fundamental changes from a central planning to a market economy. The main aim of this transition is the privatization process which has to change the structure of Polish economy. Privatization has to establish more favourable ways of utilizing the productive capacity of state enterprises and create better conditions to compete on the market. The Privatization process for Polish state enterprises was defined in the Act on the Privatization of State Enterprises of 13 July 1990. According to this Act state enterprises can be privatized in capital or liquidation methods. The capital method has been applied to the privatization of Polish ports. In 1991 the major Polish ports were transformed into a State Treasury shareholder company. The holding company was used in the first stage of privatization. Gdynia was the first port which started this process building the real model of holding. Another important element connected with the structural transformation of Polish ports is the separation of operational and management roles. According to the Act on Ports, the Port Authority is also responsible for the development of the commercial, industrial and distribution services. This Act will also enable Poland to adapt economic and legal regulations which are similar to those in the European Union ports.

The evolution of containerization in East Asia

This paper examines the development and growth of container traffic in the Asia-Pacific region. It is hypothesised that containerization is losing its national character as the geography of container transport changes port hierarchies where only a few ports have become locationally favorable. The organizatioon of the paper is straightforward. First, the development and growth of container traffic in the Asia-Pacific region is examined in order to provide understanding of changes associated with containerization. Second, the role of selected Asian-Pacific ports as key economic players is reviewed, and container development in each port is analysed so as to measure the differences explaining the position of Asian-Pacific ports in the maritime system. Third, the degree of concentration and competition that exist among the container ports of the region is analysed with a view to evaluate what rate of expansion can be expected in the foreseeable future that will shape the network of the container market in the region. The paper concludes on a possible research agenda.
