Abstract This article describes the trend towards European green initiatives in the transport sector. The introduction of green logistics management and green policy in Europe has been analysed to understand better the positive impact of green policy on environment, society and economy. With the most recent EU initiatives in the field of green logistics, intermodality has become the platform for green logistics development in the EU. This stimulated a complete study of the case of South East Europe. The perspective of intermodal infrastructure development, the use of intermodality and the environmental impact of the transport sector has been analysed to build an appropriate model for a macro green logistics strategy for South East Europe, where Green transport corridors should be exposed as the main goal. In our proposal of a seven-pillar strategy, all parties, including governmental institutions, manufacturing industry and logistics operators, should take an active part, enabling industry to co-create a ...

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.

AbstractThe paper presents a wider perspective on possibilities to develop a regional strategy for efficient management of the transport industry in the region of the Balkans. The focus is mainly on ports, their actual and future role in transport industry and regional economy. A complete overview of the actual situation of port industry and inland infrastructure is presented. Based on a seven pillar model, other key elements, such as Information Technology (IT) systems in use, documentary procedures and managing strategies of ports in the Balkans were analysed. The main proposal is connected to the development of a regional role for ports on the eastern coast of the Adriatic Sea in order to secure port regionalization and specialization. On this basis, the inland infrastructure and other supporting elements as IT platforms and documentary procedures should be developed accordingly. The entire region and economy should benefit from such cooperation as new supply chains might be attracted.

AbstractThe article deals with a current problem faced by all ports: how to enable container terminals to keep up with the development of container ships, which, due to economies of scale, are constantly increasing in size. One solution that can help small container ports solve this problem is a use of a Decision Support Tool (DST). The DST is based on simulations and identifications of the container terminal components that require optimization for the reception of the desired ship size in a given port. It consists of the six parts of the terminal that define the operational ship-to-shore system that determines the quality of service when a ship is in the port. A DST was tested on the real data of twelve Mediterranean container terminals. Special focus was made on the optimization possibilities of the container terminal in the port of Koper.

In this article, we analysed container throughput in Northern Adriatic ports (NAPs) in period 1990–2015. Along with well-known market indices method, we also discussed a simple two-state Markov chain model for qualitative forecasting of containers throughput evaluation, and the Lotka-Volterra dynamical model to identify possible competition/cooperation relationships between NAPs. In the end is given a comparison of throughput dynamics of NAPs and ports in Le Havre – Hamburg region.

Continuing – and constant - growth in world maritime traffic, and the increasing number of cruise ships in the Adriatic-Ionian region, was the motive for this study. Maritime passenger transport represents important part of tourism. This paper deals with maritime passenger transport, more specifically, maritime cruise traffic. Based on the data gathered through the EA SEA-WAY project, the authors have prepared an overview of the state of cruise ship traffic in the Adriatic-Ionian region, identified key passenger ports holding the largest traffic shares and indicated a possible development scenario of the cruise traffic within the region.

The ports of the northern Adriatic are ranged in three countries. Kopers is the only one in Slovenia and therefore of distinctive import to the country, which with its limited coastal space has no other options for expanding maritime trade than increasing the capacity of this one extant port. The state of Slovenia is the largest shareholder and the future development of the port depends on decisions made by the Ministry of Infrastructure. The increase in container throughput in the Port of Koper requires a reconstruction and extension of the current container terminal as an absolute priority. Regarding economic sustainability, the extension must be in line with the estimated growth of traffic as well as with the exploitation of present and future terminal capacities. The occasional expansion projects must fulfill environmental and safety requirements. For large container vessels (LOA more than 330 m) calling at the Port of Koper the safety of the berthing and departure conditions have to be simulated under various metocean conditions. At the same time manoeuvres should not be intrusive – expected propeller wash or bottom wash phenomena must be analysed. When large powerful container vessels are manoeuvring in shallow water bottom wash is expected and because sediments at the port are quite contaminated with mercury some negative environmental influence is expected. The most important expected investment in the container terminal is therefore extending (enlarging) and deepening the berth. The paper will present statistics and methods supporting container terminal enlargement and a safety and environmental assessment derived from the use of a ship handling simulator.

With the European Union growing eastwards and with the establishment of important production facilities in the countries of Central and Eastern Europe, the hinterland potential is bound to grow even more. The strategic goal of the Port of Koper is to become one of the best ports in the Southern Europe, to develop from a handling port into a commodity distributional centre. Penetrating and exploiting these markets demands cooperation (integration) with the existing inland terminals (logistic centres) and establishing of new ones positioned between Eastern and Western Europe. This paper aims to present and analyse: (I) supply chains of the flow of goods through the Port of Koper to/from the countries of Central and Eastern Europe, (II) the current state and strategies to optimize the flow of goods, (III) market potential, investments in new terminals and capacities. KEY WORDS: Port of Koper, strategies, goals, supply chains, integration, new terminals, market potential, investments
