Efficient Port Pricing: A New Methodology Applied to Spanish Commercial Ports
2000
This paper presents a methodology for determining efficient tariffs for the services provided by commercial ports. With this method, efficient unit profits can be obtained for the services offered and their margins of sensitivity can be found. This allows port authorities to determine what actions should be taken with regard to tariffs and/or variable costs in order to optimise their economic results. At the same time, shadow prices of port resources and their limits of sensitivity can be obtained, thus providing port authorities with orientation regarding which resources should be augmented and by how much. In the early 90's, this methodology was applied to all Spanish commercial ports and…
Stochastic modeling of Supramax spot and forward freight rates
2015
We conducted an empirical analysis of Supramax spot rates and propose a continuous time process to model the dynamics. The model incorporates features relevant for shipping freight rates, freight rate volatility that varies over time, sudden, big freight rate movements, and short-term, mean-reverting price trends. This suggests some degree of short-term predictability of Supramax spot rates, making shipping different from traditional asset markets, like stocks and currencies, and also most commodity markets. However, this does not imply that arbitrage profits are easily picked up in this market, as, financially speaking, spot freight rates are not traded assets. We instead focus on the rela…
Basic Elements of Cyber Security for a Smart Terminal Process
2023
Global maritime transportation and logistics systems are essential parts of critical infrastructures in every society, and a crucial part of maritime logistics processes are seaports. Digitalization helps improve the efficiency of terminal systems in the processes of these ports. In Finland this development is going on and it is called SMARTER research program. In the best cases, digitalization can also promote the reduction of emissions by optimizing port operations and enhancing cargo and people flows while improving the experience for all stakeholders. The improvement of port processes relies on the development of Information and Communication Technology (ICT) and as well as on Industria…
Cyber Threat Analysis in Smart Terminal Systems
2023
Cyber threats create significant factors that challenge traditional threat prevention mechanisms in harbor areas and port terminals. It has been recognized that understanding security functionalities in the harbor area is based on a more traditional experience of what it requires. It is not enough that the maritime and harbor ecosystem repeats only physical security service routines regarding random checks of passengers and vehicles and customs functions on cargo and passenger transportation. Smart environments and infrastructures are widely expanded in urban areas and create more challenges if old practices are combined with new technologies and functionalities. Traditional threats have ch…
