Drivers for migration of an intermodal network hub from a port to an inland terminal

This paper explores influences on a migration of hub status in an intermodal network from a port to an inland node by following the life cycle of an inland terminal development. The methodology is a longitudinal case study of the Swedish intermodal system over a period of 20 years, based on documentation, interviews and action research. We observe the changing roles of the Port of Gothenburg and the Falköping terminal at different time periods. These changes are then discussed and influences identified for this migration and new centralisation inland. The longitudinal approach allows a life cycle perspective which reveals the importance of initial public infrastructure development and then the operational importance of integration between shipper and intermodal transport and terminal provision in controlling the network. The integration of the inland terminal in regional logistics strategies was also found to be important in attracting port flows to be transported via the inland hub to be containerised.

Network analysis of container barge transport in the port of Antwerp by means of simulation

Inland navigation plays an important role in the hinterland access of the port of Antwerp. In this paper alternative bundling strategies for container barge transport in the port of Antwerp are analyzed. Four alternative hub scenarios are simulated and compared with the current situation with respect to the operational characteristics of the network. Discrete event simulation is used to analyze the impact on waiting times and capacity utilization at potential hubs and at sea terminals. The hub scenarios under investigation are the organization of an intermodal barge hub on the right river bank, an intermodal hub on the left river bank, a first multihub scenario with a local collection/distribution network and a potentially improved multihub scenario taking into account the specific structure of the port of Antwerp. The second multihub scenario offers most opportunities for reducing the turnaround time of all inland terminals. All hub scenarios lead to important efficiency improvements in the handling of barges at sea terminals.     

Development and application of a dynamic model for road port access and its impacts on port-city relationship indicators

Seaports are major intermodal structures in the global supply chain, where multiple stakeholders search for profitable and resilient maritime lines. Shipowners reduce the distance between the northern and southern hemispheres by connecting hub ports. Hosting a global hub port implies competitive advantages to the municipality. However, operational bottlenecks loosen the port-city relationship. One of the main conflicts in this relation is the land port access, a hard-to-be-mapped, random operation. The traffic flow rise noticed in developed countries' ports and, more recently, in emerging markets, causes congestion and air pollutant emissions in terminal surroundings. Current models for road port access are static, single-window non-synchronized truck appointment systems. As a contribution, this case study develops a dynamic model of road port access. Also, it verifies the effectiveness of its application in the port-city relationship indicators in an emerging market global hub port, the Port of Santos, faced with ports of developed countries, prospecting optimal conditions to its implementation in an environment with significant institutional obstacles.     

Development of seaport–dry port dyads: two cases from Northern Europe

An increase in sea freight flows generates an almost proportional increase in inland freight flows, and what takes place inland will influence the ability of intermodal transport systems to further accommodate the growth of international trade. This could be facilitated by dry ports, which have been developed to support seaport operations as well as the overall operations of intermodal transport systems.The aim of this paper is to develop the Wilmsmeier et al. (2011) framework of directional development by taking into account development over time. The purpose is to contribute to the understanding of the development of seaport–dry port dyads by the analysis of two in-depth case studies from Northern Europe. A qualitative research strategy is applied to increase understanding of the development. The results contribute to earlier studies of spatial development of seaport–dry port development by taking into account development over time and by increasing the understanding of the actors, the types of dry ports and the services influencing the development of the dyads.     

Understanding hinterland service integration by shipping lines and terminal operators: a theoretical and empirical analysis

In the present competitive environment of ports, the key determinant in port competition is the ability of a port to be integrated into the local maritime and hinterland transportation chain. Creating effective integrated hinterland chains requires the coordination of several actors both in port and the hinterland. By making use of insights from Transaction Cost Economics and Resource-based View, the paper helps to understand why and how shipping lines and terminal operating companies enlarge their scope in intermodal transport and in inland terminals. The paper discusses a number of cases from the Hamburg–Le Havre range, where shipping lines and terminal operating companies have changed their scope of activities in ports and hinterland networks. After the theoretical and empirical analysis the papers draws conclusions on the explanatory power of the theories in understanding hinterland service integration by shipping lines and terminal operators.
