Opis:
The container yard is the key element of any modern container terminal. The huge amount of boxes dwelling on the operational areas of the terminals could occupy a lot of space, since one-time storage capacity of the container mega terminal handling over one million TEUs annually is something around 20 000 TEUs. The ecological pressure imposed on modern container terminal does not permit to allocate for this storage large land areas, thus forcing the box stacks grow high. The selection of the individual boxes becomes a complex and time-consuming procedure, demanding a lot of technological resources and deteriorating the service quality. The predicted combinatorial growth of redundant moves needed to clear the access to the individual container is aggravated by the well-known and widely discussed ‘sinking effect’, when containers arrived earlier are gradually covered by the ones arriving afterwards. While the random selection could be adequately assessed by combinatorial methods, the ‘sinking effect’ allows neither intuitive consideration, nor any traditional mathematical means. The only practical way to treat this problem today is in simulation, but the simulation itself causes yet another problem: the problem of model adequacy. This study deals with one possible approach to the problem designated to prove its validity and adequacy, without which the simulation has naught gnoseological value.

Opis:
In this article the attempt has been made to construct hierarchical model of container ports throughput development. The presented hierarchical approach uses the relationships of development of global economy and container flows at different geographical levels: global (container throughput in all seaport on the world), regional (container throughput in the Baltic seaports) and national (container throughput in Polish seaports). Model have been evaluated for their fit and usefulness for predictive purposes.

Opis:
Nowadays managers and decision-makers around the world seek every opportunity to lower costs of the ship’s mooring time at seaports. In this article, main operations taking place at maritime container terminals are first disaggregated in several elementary activities. Then the vessel cycle time is analysed while separately investigating the STS (Ship to Shore) crane cycle time, the RTG (Rubber-Tyred Gantry) crane work cycle time and the IMV (Internal Movement Vehicle) transfer time. A triangular distribution describes times of each of the container handling stages while the PERT (Program Evaluation and Review Technique) method is used to estimate the total time for all reloading activities. The paper demonstrates the proposed method effectiveness with data of Baltic Container Terminal (BCT) Gdynia. The use of formulas developed for the calculation of times of individual operations that affect the reloading of a container at maritime container terminals enables an in-depth assessment of the effectiveness of the reloading processes. Thus, the proposed tool gives terminal managers opportunity to track which stage of the container reloading consumes most time and generates biggest costs.

Opis:
The simulation as a tool for the design of port and terminals has emerged as an answer for the demand to enhance the quality and reliability of the project results. Very high costs of the project solution implementation and practically total lack of liquidity of transport infrastructure objects always induced the immense commercial risks in the terminal business. Lately these risks have multiplied significantly due to rapid changes on the global and regional markets of transport services. Today, many experts come to see this volatility as an indicator of the next phase in development of the global trade system and the derivative cargo transportation system, specifically the state of temporal saturation. The shift of the global goods volumes from quick and steady growth to relatively small fluctuations around constant values causes quick oscillations in re-distribution of demand over the oversized supply. This new business and economic environment seriously affected the paradigm of transport terminal design and development techniques. The new operational environment of terminals put a request for the designers to arrange the results not in terms of “point”, but in terms of “functions”. Eventually it resulted in development of the modern object-oriented model approach. The wide spread of this approach witnesses the objective demand for this discipline, while in many aspects it remains in the intuitive (pre-paradigmal) phase of its development. The main reason for it is in the problem definition itself, which usually is formulated as the simulation of a given terminal. At the same time, the task is to assess the operational characteristics of the terminal engaged in processing of a given combination of cargo flows. Consequently, it is not the terminal that should be simulated, but the processes of cargo flows handling performed by this terminal under investigation. Another problem that restricts the practical spread of simulation is in the model adequacy. A model which adequacy is not proved has no gnoseological value at all. The paper describes the approach aimed at development of the models with the features discussed above.

Opis:
By developing possible solutions for Saudi ports to limit the increase in damage to the marine ecosystem, the random system for estimating the waiting time of ships in Saudi ports has been developed as a model to guide the application of the multiple benefits to the beneficiaries such as ship owners, shipping companies and port authorities so that it is applied to create multiple economic and environmental savings. An imperative optimization model for solving container slot allocation problems for time-sensitive commodities under the dynamics of port congestion pricing. The proposed new pricing mechanism has proven to be effective when compared to a generic slot allocation model that does not take into account shipping time limits and port congestion, with results showing that the proposed pricing scheme can significantly improve ship companies' revenues and improve customer satiation. In terms of reducing carbon emissions from the ship's stay for a longer period at the docks.

Opis:
The main subject of research involves the global freight market in the sector of container shipping, and in particular the mechanism for setting up freight rates. The aim of research is to identify and analyse the features and characteristics typical of this market, resulting from the character of market mechanism, as well as to indicate factors which determine market fluctuations and evaluate its impact for the carriers and shippers. Moreover, the causes and effects of fluctuations in effective demand and potential supply in the sector of freight market were identified in terms of their impact on freight rates. The analysis includes three main types of container markets, existing today on a global scale, and characterizes the strategies and modes of behaviour of global container operators undertaking activity on these markets. By applying the theory of mass random service and queueing theory to examine the container freight market mechanisms the method of freight rates short-term forecasting was presented which can be used as an instrument for taking decisions in the sector of global maritime logistics.

Opis:
Comprehensive forecasting of future volumes of container traffic in seaports is important when it comes to port development, including investments, especially in relation to costly transport infrastructure (e.g. new terminals). The aim of this article is to present a specific, simplified model of demand forecasting for container traffic in seaports as well as to give a practical verification of the model in the Polish seaport sector. The model consists of relevant indexes of containerisation (values, dynamics) referring to the macroeconomic characteristics of the country of cargo origin as well as destination-predictor variables (e.g. population, foreign trade, gross domestic product). This method will facilitate the evaluation of three basic segments of the container market: foreign trade services, maritime transit flows and land transit flows. International comparisons of indexes (benchmarking) as well as extrapolations of future changes can support this prediction process. A practical implementation of this research has enabled us to calculate that the total container volume in Poland will be approximately 4.69 – 4.87 million TEU by the year 2023.

Opis:
A major share of all empty container positioning (deadheading) is resulting from imbalances with regard to container sizes (20ft/40ft). In order to reduce the shipments of 'containerised air' a new type of container has been developed by the author: The Tworty Boxes can either be used as a standard 20ft or in coupled condition as a 40ft container. The outside appearance resembles any standard 20ft container. However the Tworty Box is unique in that it has an additional door at the front side that opens to the inside. This door can be fixed to the ceiling and by using of bonding elements another Tworty Box can be joined up, thereby creating the full 40ft inside space. Operated as a single 20ft box the additional door remains locked, access is only through the existing standard door. Tworty Boxes do not require any additional components and fulfil all ISO and CSC requirements.

Opis:
The research addresses the problem of an ultra-large container ship mathematical model adjustment based on sea trials. In order to verify the model’s adequacy, simulated data had to be compared to the trial report data, which was obtained in ballast condition with significant trim. In such circumstances, model coefficients cannot be calculated by known methods and have to be corrected as per trial data. It is proposed to determine translational motion coefficients first. To get optimal results, it was also proposed to divide the objective function into kinematic and dynamic components, with each component being assigned a weighting factor. A separate objective function component was assigned to the zig-zag maneuver, which includes the first and second overshoot angles.

The aim of this paper is to understand the real activity and operating situation of container ships in order to improve navigation efficiency. The study focused on the navigation for an entire ship voyage to understand the real activity of container ships using the historical ship navigation based on Automatic Identification System (AIS) data, which is possible so as to unveil the characteristics of real ship activity. The analysis considers ship voyages in the Seto Inland Sea and its oceanic waters, which are the primary traffic routes for container transportation particularly for China, Japan, and South Korea. The results of this study can be used to improve the efficiency of container ships and develop a smoother maritime transportation.

The main research issue refers to the identification and analysis of the key features and trends revealed on the global maritime container transport market in the years 2020-2022, as well as its general assessment in terms of the effects that such a highly concentrated market's supply side can cause for shippers and container shipping operators. The research is aimed at determining the main premises and factors stimulating the consolidation processes of the container shipping operators and ongoing market vertical and horizontal integration, as well as assessing the risks and effects resulting from maintaining the current system of regulation of this oligopolistic market. While conducting this research, the following methods were applied: factor analysis (FA), market analysis (MA) based on statistical data concerning the supply side, as well as desk research (DR), i.e. in-depth analysis of many reports, opinions, bulletins and data issued by international maritime organisations as well as research institutes. The obtained research results indicate that:1. the very advanced consolidation processes among the leading container shipping operators and, consequently, further integration of the container market, radically changes the balance of power in favour of shipping operators and creates the potential to generate serious disruptions in this market and other links in the global supply chains, 2/ regulatory antitrust authorities need to take appropriate regulatory action to limit their market power via legal measures regarding competition.

Opis:
The box selectivity in operational stack of container terminal is a quite common and long studied question. The pure random choice is governed by the theory of probability offering some combinatorial estimations. The introduction of operational rules like import/export separation, storage by shipping lines, sorting by rail or truck transportation etc., as well as the most notorious ‘sinking’ effect, i.e. covering of boxes arrived earlier by next cargo parties – all these blur the clear algebraiс picture and lead to appearance of many heuristic outlooks of the problem. A new impetus to this problem in last decades was given by the rapid development of IT, AI and simulation techniques. There are quite many examples of the models described in the scientific publication reflecting many real and arbitrary terminals, which embed very advanced and complicated mechanisms reflecting selected features and strategies. Unfortunately, these models usually are created ad hoc, with some pragmatic objectives and under the demand of closest possible proximity to the simulating objects. There are much less models designated to pure scientific study of the deep inner mechanisms responsible for the primal behavior of the operating container stack, enabling to introduce step by step new rules and restrictions, providing regular proving of every next stage’s adequacy and easy to use. This paper describes one attempt of this kind to create a new theoretical tool to put into the regular toolkit of the container terminal designer. The study starts with mathematical (combinatorial) considerations, proceeds with some restrictions caused by physical and technological characteristics, and ends up with the simulation model, which adequacy is confirmed by practical results.

Other major and even minor ports could benefit from the operation of this innovative type of vessel as well as it improves the efficiency and at the same time reduces the ecological footprint of intra-port container haulage. Additionally it can even facilitate container handling at places which are not suited at all for this kind of operation.
