    Opis:
    Causative chain (CC) is a failure chain that cause accident as an outcome product of the second step of MOP model, namely line relation analysis (LRA). This CC is a connection of several causative factors (CF), an outcome product of first step of MOP model, namely corner analysis (CA). MOP Model is an abbreviation from 4M Overturned Pyramid, created by authors by combining 2 accident analysis models. There are two steps in this model, namely CA and LRA. Utilizing this model can know what is CF that happen dominantly to the accidents and what is a danger CC that characterize accidents in a certain place and certain period. By knowing the characteristics, the preventive action can be decided to decrease the number of accident in the next period. The aim of this paper is providing the development of MOP Model that has been upgraded and understanding the characteristics of each type accident. The data that is analyzed in this paper is Japanese accidents from 2008 until 2013, which is available on Japan Transportation Safety Board (JTSB)’s website. The analysis shows that every type of accidents has a unique characteristic, shown by their CFs and CCs. However, Man Factor is still playing role to the system dominantly.

    Opis:
    Ship collision is a hazardous event within the chain of maritime transport. Collisions may result in human losses, adverse economic consequences, and environmental damages causing significant impact to local societies and related activities. A major factor in any risk analysis concerning ship collisions is the probability of these collisions occurring. The purpose of this study is to assess the probability of ship-to-ship collision in the Aegean Sea. The basic concept of the developed model is to (statistically) simulate traffic flow in the area of interest and determine the collision candidates; this will be implemented in a pilot study in a segment of the Aegean Sea. The input of this effort is based on values that are extracted from statistical analysis of the international fleet in combination with the study of maps depicting traffic flow in the studied area. Hence, it does not employ detailed AIS data. The obtained results are presented and their agreement with actual incidents is discussed in depth. The paper concludes with interesting insights of the aforementioned tasks.

    Opis:
    This paper aims at evaluating the collision risk between the encountering vessels under time- -variant CPA situations and then assessing the maritime traffic characteristics. Radar and AIS data are collected from Mokpo VTS in Korea. All crossing vessels that are navigating within CPA 1 miles of Mokpo-Gu waterway are analyzed. The maritime traffic characteristics is analyzed by surveying the distribution of CPA as a function of TCPA. To make it clear, the traffic operating rate in the Mokpo waterway is also computed. The averages of CPA and TCPA were observed until the encountered vessels pass safety each other after they come in a certain ship domain. As a consequence, the distribution of CPA as a function of TCPA gives a useful information to evaluate the maritime traffic safety.
    Celem artykułu jest ocena ryzyka kolizji statków w funkcji zmiany wartości czasu do kolizji, a na tej podstawie oszacowanie charakterystyk determinujących ruch morski. Dane z radarów oraz systemu AIS zostały zarejestrowane w systemie VTS Mokpo w Korei. Przeanalizowano wszystkie przypadki przecinania się tras statków na podejściu do Mokpo-Gu w przypadku, gdy odległość minimalna (CPA) była mniejsza niż jedna mila morska. Charakterystyka ruchu morskiego opisana została poprzez wyznaczenie rozkładu wartości największego zbliżenia statków jako funkcji czasu do nadmiernego zbliżenia (TCPA). Dla pełnej jasności obliczono również współczynnik przepustowości drogi wodnej Mokpo. Opisano średnie wartości odległości największego zbliżenia oraz czasu do wystąpienia CPA bez względu na przekroczenia granic domeny obserwowanych statków. W konsekwencji wyznaczono rozkład wartości CPA jako funkcję TCPA, co okazuje się użyteczne dla oceny bezpieczeństwa ruchu morskiego.

    Opis:
    In the maritime domain, the risk is evaluated within the framework of Formal Safety Assessment (FSA), introduced by International Maritime Organization in 2002. Although the FSA has become internationally recognized and recommended method, the definition, which is adopted there, to describe the risk, seems to be too narrow to reflect properly the actual content of the FSA. Therefore this article discusses methodological requirements for the risk perspective, which is appropriate for risk management in the maritime domain with the special attention to maritime transportation systems (MTS). This perspective considers risk as a set encompassing the following: the set of plausible scenarios leading to an accident, the likelihoods of the unwanted events within the scenarios and the consequences of the events. These elements are conditional upon the available knowledge about the analyzed system, and understanding of the system behaviour, therefore these two are inherent parts of risk analysis, and need to be included in the risk description.

    Opis:
    One of the areas of decision support in the navigational ship conduct process is a Traffic Separation Scheme. TSSs are established in areas with high traffic density, often near the shore and in port approaches. The main purpose of these schemes is to improve maritime safety by channeling vessel traffic into streams. Traffic regulations as well as ships behavior in real conditions in chosen TSSs have been analyzed in order to develop decision support algorithms.

    Opis:
    Vessel traffic flow is a key parameter for channel-through capacity and is of great significance to vessel traffic management, channel and port design and navigational risk evaluation. Based on the study of parameters of characteristics of vessel traffic flow related to channel-through capacity, this paper puts forward a brand-new mathematical model for one-way channel-through capacity in which parameters of channel length, vessel arrival rate and velocity difference in different vessels are involved and a theoretical calculating mechanism for the channel-through capacity is provided. In order to verify availability and reliability of the model, extensive simulation studies have been carried out and based on the historical AIS data, an analytical case study on the Xiazhimen Channel validating the proposed model is presented. Both simulation studies and the case study show that the proposed model is valid and all relative parameters can be readjusted and optimized to further improve the channel-through capacity. Thus, all studies demonstrate that the model is valuable for channel design and vessel management.

    Opis:
    The e-navigation strategy of the International Maritime Organization (IMO) aims to improve the safety of maritime traffic by increasing cooperation between several maritime stakeholders. The COSINUS (Bolles et al., 2014) project contributes to such a strategy by enabling an automated data exchange (observations, routes and maneuver plans) between ship-side and shore-side navigational systems, developing useful sensor fusion applications upon the new information available from data exchange and introducing new Human Machine Interfaces (HMIs) to support the users of navigation systems. The project shows potential for improvement in maritime traffic safety by ensuring continuous awareness to all participants involved through sensor fusion applications, i.e. by providing all participants (mobile and stationary navigation systems) with a complete view at all times. These applications include detection of critical situations like radar shadowing areas, early and accurate prediction of potential collisions or closest point of approach (CPA) based on the exchanged routes, and improving the accuracy of radars by ensuring high quality data for obstructed or far away routes. The new HMI concepts introduced within the COSINUS project aim at highlighting critical maritime traffic situations. Thus, the users of such navigation systems supported with COSINUS facilities can easily detect such critical situations and react efficiently to avoid collisions, possible crowded areas and inefficient routes.

    Opis:
    Maritime traffic situations is regulated in the Convention on the International Regulations for Preventing Collisions at Sea (COLREGs), but how well are these rules followed by officers on board vessels? When the world shipping fleet grow and the traffic becomes more intensive, the risk of collision increase. By analysing AIS data from vessels in the traffic separation scheme Bornholmsgat during 24 hours in December 2013, 421 traffic situations were found where the passing distance between the vessels were less than 1.5 nautical miles. The compliance with the Convention on the International Regulations for Preventing Collisions at Sea (COLREGs) seems to be good, but the average avoiding action is less than the recommended manoeuver.

    Opis:
    The GNSS positioning performance is commonly defined and described in terms unspecified to particular GNSS-based application. The approach causes difficulties to GNSS application developers, operators, and users, rendering the impact assessment of GNSS performance on the GNSS application Quality of Service (QoS) particularly difficult. Here the Probability of Occurrence (PoO) Model is introduced, which allows for a risk assessment of the probability for the GNSS positioning accuracy failure to meet the requirements of the particular GNSS-based application. The proposed PoO Model development procedure requires a large set of position estimation errors observations, which shall cover a range of classes of positioning environment (space weather, troposphere, multi-path etc.) disturbances affecting GNSS positioning accuracy. As result, the PoO Model becomes a tool that returns the probability of failure in meeting the positioning accuracy requirements of the GNSS applications considered, thus providing the input for a GNSS deployment risk assessment. The proposed PoO Model and its development procedure are demonstrated in the case of polar region positioning environment, with raw GNSS pseudorange observations taken at the International GNSS Service (IGS) Network reference station Iqualuit, Canada are used for the PoO Model development. The PoO Model proof-of-principle is then used to estimate the probability of the unmet required positioning accuracy for a number of polar maritime navigation applications. Manuscript concludes with a discussion of the PoO Model benefits and shortcomings, a summary of contribution, and intentions for the future research.

    In order to study the characteristics of mixed vessel traffic flow, based on classical head distance model and probability analysis, by studying the combination time head way of different vessel-following sequences, the capacity model of mixed vessels traffic flow was established. Through analyzing two representative types of vessels, research results indicate that the capacity of mixed traffic increase with the traffic flow speed in a certain speed range, but the increasing trend slow down. The closer length and inertial stopping distance of different kind vessels are, the more capacity of mixed traffic increases. And the influence of reaction time on the capacity is related to proportion of different kind vessels.

    Opis:
    A conceptual model is proposed to monitor marine traffic through precautionary areas, which can provide us with a systematic control of passage planning in ports. On one hand, vessel traffic control has its special features and is fundamentally different from highway, air and pedestrian traffic control. The existing traffic control systems cannot be simply extended to vessel traffic control without addressing marine traffic features. On the other hand, existing vessel traffic control focuses on one ship or two ships but does not address the flows of marine traffic.

    Opis:
    Collision avoidance is one of the high-level safety objectives and requires a complete and reliable description of maritime traffic situation. A combined use of data provided by independent data sources is an approach to improve the accuracy and integrity of traffic situation related information. In this paper we study the usage of radar images for automatic identification system (AIS) and radar fusion. Therefore we simulate synthetic radar images and evaluate the tracking performance of the particle filter algorithm as the most promising filter approach. During the filter process the algorithm estimates the target position and velocity which we finally compare with the known position of the simulation. This approach allows the performance analysis of the particle filter for vessel tracking on radar images. In a second extended simulation we add the respective AIS information of the target vessel and study the gained level of improvement for the particle filter approach. The work of this paper is integrated in the research and development activities of DLR Institute of Communications and Navigation dealing with the introduction of data and system integrity into the maritime traffic system. One of the aimed objectives is the automatic assessment of the traffic situation aboard a vessel including integrity information.

    This article presents a dedicated kinematic method of determining a safe fairway bend width with a specific turn angle and arc radius as the function of ship parameters and prevailing navigational conditions on the fairway. The assumed approach takes into consideration monoeuvring and navigational components of the safe fairway bend width. The method is based on an analysis of the results of numerical tests conducted on a model representing all physically possible movements of ship's centre of gravity in the bend. The developed method was initially verified on the Ińskie bend, part of the Świnoujście-Szczecin fairway.

    Opis:
    In this manuscript, development and preliminary results of a simulation based risk modeling study for the Strait of Istanbul is presented. The goal of this research is to analyze the risks involved in the transit vessel traffic in the Strait of Istanbul. In the first step of the study, the transit vessel traffic system in the Strait of Istanbul has been investigated and a simulation model has been developed. The model gives due consideration to current traffic rules and regulations, transit vessel profiles and schedules, pilotage and tugboat services, local traffic, meteorological and geographical conditions. Regarding risk assessment, two sets of factors are used to evaluate the risk of accident in the Strait: the proba-bility of an accident and its potential consequences, as estimated and evaluated at various points along the Strait. Experience has shown that maritime accident occurrences can be very dissimilar from one another and therefore, probabilistic analysis of accidents should not be done independent of the factors affecting them. Thus, in this study, we have focused on the conditional probability of an accident, under a given setting of various accident causing factors. Unfortunately, historical accident data is by far insufficient for a proper sta-tistical consideration of all possible settings of these factors. Therefore, subject-expert opinion is relied upon in estimating these conditional accident probabilities. Assessment of the consequences of a given accident (in terms of its effects on human life, traffic efficiency, property and environment) was also accomplished using a similar approach. Finally, by integrating these assessments into the developed simulation model, the risks observed by each vessel at each risk slice are calculated in regard to the natural and man-made conditions surrounding. A sce-nario analysis is performed to evaluate the characteristics of the accident risk as the vessel moves along the Strait. This analysis allows us to investigate how various factors impact risk. These factors include vessel ar-rival rates, scheduling policies, pilotage service, overtaking and pursuit rules, and local traffic density. Policy indications are made based on the results of these scenarios.

    Opis:
    4M Overturned Pyramid (MOP) model is a new model, proposed by authors, to characterized MTS which is adopting epidemiological model that determines causes of accidents, including not only active failures but also latent failures and barriers. This model is still being developed. One of utilization of MOP model is characterizing accidents in MTS, i.e. collision in Indonesia and Japan that is written in this paper. The aim of this paper is to show the characteristics of ship collision accidents that occur both in Indonesian and Japanese maritime traffic systems. There were 22 collision cases in 2008–2012 (8 cases in Indonesia and 14 cases in Japan). The characteristics presented in this paper show failure events at every stage of the three accident development stages (the beginning of an accident, the accident itself, and the evacuation process).

    Opis:
    The routing problem of small island ports is, in many cases, firmly dependent on country topology, e.g., how to connect islands with a main (home) port, where the order of stops can be different, especially if there are not enough passengers or cargo waiting to be transported to or from every port. Thus, we need a capable optimization tool with which we can adapt each route for an appropriate time schedule; for example, some routes in one cycle can touch each island (forwards or backwards) but some routes can be incomplete, to touch only a few of them. The carrier has to find space for price-cutting (lower prices per journey – more passengers on board), to be more attractive in free-market competition. In such route optimization, we have to interconnect minimal transport cost with maximal revenue (money from tickets), which could be a very demanding task (a non-linear objective cost function). Instead of a non-linear polynomial optimization, which can be very complicated and time-consuming, the network optimization methodology could be efficiently applied. The main goal is to find more efficient routes, to decrease expenses and to increase revenue at the same time (dual mini/max problem).

    Opis:
    Evasive action in ship-ship encounter has to be carried out on time and in line with the international convention on collision regulation – COLREG. The convention not only includes a set of rules defining types of relations between encountering ships but also indicates appropriate action to be taken in a given encounter. One of such encounters is crossing, where, in case of a collision situation, a give-way ship has to take an appropriate action in due time. However, a stand-on vessel is also given an opportunity to manoeuver, if it is made clear to her that the other ship is not fulfilling her obligations. However, it is difficult to specify, at which point in time in the course of an encounter, the stand-on ship has to take an action in order to avoid collision. It is understandable, as this parameter depends on numerous factors, both endogenous (e.g. ship characteristics, her maneuverability), and exogenous (e.g. type of encounter, weather conditions). Therefore in this paper we make an attempt towards the definition of the critical area for a maneuver of a stand-on ship, in the situation where the give-way vessel does not take an action. This is determined with the use of a hydrodynamic model of ship motion, and series of simulations conducted for several types of encountering ships under various conditions. Once determined, the critical area demarcates the no-go area around the own ship, where any other ships on collision courses must not enter. Otherwise a collision cannot be avoided by an action of one ship alone.

    “Safe voyage from berth to berth”: This is the goal of all e-Navigation strains driven by new technologies, new infrastructures, and new organizational structures on bridge, on shore, as well as in the cloud. To facilitate these efforts suitable engineering and safety/risk assessment methods are required. Understanding maritime transportation as a sociotechnical system allows the usage of system-engineering methods. Simulation-based test beds for verification and validation (V +V) of e-Navigation technologies are important methods to obtain functional safety and reliability. The modeling and simulation toolset HAGGIS is a cosimulation system for the evaluation of e-Navigation concepts and systems. It provides a maritime traffic simulator and a physical world (n-body) simulator and services for finding rare events of failures. HAGGIS is accompanied by the physical test bed LABSKAUS, which implements a reference port and waterways. This paper describes an integrated and seamless approach for developing new e-Navigation technologies starting with virtual simulation-based safety assessment and ending in physical real-world demonstrations. It gives an overview of the actual test bed and introduces requirements, concepts and elements of HAGGIS and LABSKAUS, which are joined in the e-Maritime Integrated Reference Platform (eMIR) test bed.

    Opis:
    Safety of navigation is especially challenging and critical when a ship approaches and manoeuvres in harbour areas. Improving the safety especially in the first and last phase of a voyage is crucial and requires measures addressing both the human and technical-technological elements including support systems that shall provide human operators with information relevant for decision making. The present situation is characterized by the introduction of numerous sophisticated technical and support systems often integrated with several components becoming increasingly complex. On the users end, changes are not that obvious and not that rapid as for technology. However, new approaches are under development or already in use. They are characterized by applying and adapting solutions from other transport modes. In this way, tasks and procedures on ships, that are highly safety-relevant and containing high portions of manoeuvring activities have been changed to high back-up procedures as in air planes. For port manoeuvres e.g. the system of pilot/co-pilot was introduced on ferries in a sense that one officer is operating and the other is monitoring and checking the safe performance. In cruise shipping, new structures replacing the traditional rank-based with a flexible system based on job functions. This system creates a kind of a safety net around the person conning the vessel. Each operation is cross checked before execution by one or two other persons. The first obvious consequence is higher costs due to doubling personnel. On the other hand there is also a need for a technology appropriately supporting the checking officer by enabling her or him to monitor what the conning officer is doing. “Fast-Time Manoeuvring Simulation Technology” (FTS) developed at the Institute for Innovative Ship Simulation and Maritime Systems (ISSIMS) has huge potential to fulfil this task. FTS calculates within one second of computing time up to 1000 seconds of real manoeuvring time by a very complex ship-dynamic simulation model for rudder, engine and thruster manoeuvres. It enables prompt prediction of all manoeuvres carried out by the conning officer for the observing officer, too. Predictions of path and motion status allow all officers to see whether the manoeuvring actions have at least the correct tendency or indicating the need for corrections. This new type of support is called Simulation-Augmented Manoeuvring Design and Monitoring (SAMMON) – it allows not only overlooking the next manoeuvring segment ahead but also for the following or even for series of manoeuvring segments. This technology has been used within two research projects: COSINUS (Co-operative Ship Operation in Integrated Maritime Traffic Systems) set out for implementing FTS into integrated ship bridges and to also communicate the manoeuvre plans and display it to VTS centres. Within the European project MUNIN (Maritime Unmanned Navigation through Intelligence in Networks) this technology has been used to investigate if it is possible to steer autonomous ships, in case it would be necessary.

    This paper will give an intro into the technical backbone of the EMSN and derive necessary specifications to allow for objective testing in large scale. Further, it will demonstrate the potential of EMSN as a maritime safety test-bed on the STM case. Therefore, the simulations executed within the EMSN are evaluated regarding their safety level in order to demonstrate the effects of various measures to improve safety. Based on a fuzzy logic approach, numerical Data from the EMSN Data-Tracker is used as an input to assess a present traffic situation from the perspective of a specific ship and outputs a comprehensive safety index developed by expert opinions. The safety index is used to further analyze navigators’ behavior and decisions in different maritime traffic scenarios that are executed within the EMSN.

    Opis:
    A system was set up to ingest automatic ship position reports (terrestrial and satellite AIS, LRIT) and fuse these into a Maritime Situational Picture, tracking the ships within an ocean basin‐wide area of interest in real time. Trial runs were made over several months, collecting reporting data from a number of different sources, over the Gulf of Aden and the Western Indian Ocean. Also satellite radar surveillance was carried out in order to sample the presence of non‐reporting ships. The trial showed that satellite AIS is a powerful tool for basin‐wide ship traffic monitoring; that multiple AIS satellites are needed for sufficient completeness and update rate; and that coastal AIS and LRIT still provide essential complements to the satellite AIS data. The radar survey showed that about half of the radar‐detected ships are not seen in the reporting data. The ultimate purpose of this work is to support the countries around the Horn of Africa in the fight against piracy and to help build their capacity to deliver maritime security and safety.

    The MONALISA 2.0 (ML 2.0) project aims to define the Sea Traffic Management concept (STM), where information is shared amongst all stakeholders in the maritime transport chain, including nautical officers, ports, administrations, etc. Thus, a communication and information centered approach for data exchange by System Wide Information Management principles changing from surface-based- to voyage-based-operations has been proposed. Amongst others, testing and verifying the feasibility and benefits of STM and its solutions shall be done in the European Maritime Simulator Network (EMSN), a macro simulation environment for ship handling simulators. This is an open IEEE 1278 standard network protocol enabling interactive communication between distributed simulation environments. Based on an introduction into ML 2.0, the proposed STM concept is introduced, its expected impacts are listed and Key Performance Objectives are derived. The backgrounds on the EMSN are given and it is shown how it can assist in assessing the impact of STM’s Key Performance Indicators.

    Opis:
    Safe shipping is essential for society and different measures are taken to improve maritime safety, for example through implementation of traffic separation schemes, radar surveillance and traffic management concepts. But how can maritime safety be measured to determine the effects of those implementations? In this study, a real-time maritime safety index for a ship is developed, taking into account both the probability of grounding and the probability of collision. The index is developed using fuzzy integrated systems and validated in ship handling simulator scenarios. It uses numerical data from the simulator as an input to assess the present traffic situation from the perspective of a specific ship and outputs a comprehensive index. This paper describes the concept of sea traffic management as proposed and evaluated in the EU funded STM Validation project, the motivation for developing a maritime safety index, the numerical input variables and model properties and also validates the feasibility of the approach.

    Opis:
    Vessel Traffic Services (VTS) are to improve the safety and efficiency of vessel traffic and to protect the marine environment by interacting with the ship’s traffic in monitored coastal areas. Today, VTS operators are maritime professionals with nautical education from a university or technical college and practical experience on board. This experience and nautical background is a key element of the work as a VTS operator. It is to support understanding the daily work. The current situation in the maritime domain is undergoing substantial changes, such as introducing new technologies, implementing the e-Navigation concept based on sustainable digitalization and ambitions to realize unmanned and autonomous shipping. This paper will present preliminary results of a pilot study conducted in VTS Centres along the coast of North and Baltic Sea and discuss selected options and opportunities for education and training of future VTS operators, which might not have the advantage of practical sea experience anymore.

This paper analyses the climate parameter together with traffic conditions: prevailing weather conditions as a parameter to be kept in mind for the adoption of a future ECA in the Mediterranean Sea. Preliminary results would show how marine emissions coming from existing traffic will impact the sea and land ecology in the Mediterranean area.

    Opis:
    The probability of an accident in transportation systems can serve as a measure of these systems safety or risk, depending on the objective. Therefore numerous methods and models for risk evaluation, with respect to maritime, have been developed. However, these models are either too simplified, allowing relatively fast analysis but very often missing the substantial links among the model variables, or they are too slow for effective analysis, due to computational complexity, not necessarily being backed-up with the complexity of the model itself. Thereby, this paper introduces a novel method evaluating the probability of ship-ship collision in the maritime transportation system focusing on the open sea collisions, applying the queuing theory in the simulation model. The model allows relatively fast prediction as it focuses on the specific events (e.g. accidents), instead of simulating the whole traffic. To support this hypothesis a case study is presented focusing on a selected element of transportation system in operation.

    Opis:
    The Baltic Sea is crisscrossed by several dense vessel traffic routes. Growing shipping traffic increases the likelihood of collisions. A quantitative analysis of the impact of fishing vessel traffic streams on streams of merchant vessel traffic aims to identify areas of intense traffic of this type and to assess the potential risks. The identification of intersections of fishing vessel routes and merchant shipping traffic allows us to identify spots of potential collisions. The analysis made use of the IALA IWRAP Mk2 program and AIS data collected from April 1, 2013 to March 31, 2014.

    This paper presents the methodology and research results on identification of potential users of the ESABALT system, which is targeted towards improving the situational awareness in the Baltic Sea region. We describe the technique of analysing the stakeholders involved in maritime sector processes, especially in maritime transport processes, while also taking into account their different classification criteria. The resulting list of stakeholders is used to identify system users and their classification into user profiles groups. This study will form the basis for the identification of user requirements of the ESABALT system.

    Opis:
    Traffic congestion is a wide problem in many tourist destinations. Airports are usually distant from the city centers. Hence, road and rail traffic are widely used to connect airports and city centers. In this paper, we propose zero-emission solution for connection between airport and the center at the example of Croatian city Split. Since Split has become a popular tourist destination, the number of vehicles during summer season increases. As a measure to decrease air pollution, in this paper the marine traffic by electric vessels is proposed for the route Split – airport. Seven all-electrical vessels are presented with their technical characteristics. The idea is to have zero emission transfers by sea from the center of the Split to the airport. The criteria for minimum cruising speed is set to 13 knots, which ensures that one crossing takes 30 minutes and makes it competitive with other forms of transport.

    Opis:
    Turystyka morska należy do najszybciej rozwijającego się rodzaju turystyki i przynosi znaczne dochody miastom i portom, które ją rozwijają. Rejsy wycieczkowe po Bałtyku stanowią ok. 20% całego morskiego wycieczkowego ruchu turystycznego. Jednak porty polskie, jak pokazuje przykład Gdyni, mają w tym niewielki udział. W artykule przedstawiono wyniki analizy zmian w wielkości ruchu statków wycieczkowych i liczby turystów przybywających na nich do Gdyni. Podjęte badania mają na celu ocenę i wskazanie kierunku zmian w morskim ruchu turystycznym w Gdyni w latach 1997–2016. Przedmiotem badań są zmiany liczby wizyt statków wycieczkowych i turystów w porcie gdyńskim. Dane do analizy wielkości ruchu wycieczkowców pochodzą z raportów i informacji z Zarządu Portu Gdynia S.A. w Gdyni oraz z cytowanej w pracy literatury. W pracy wykorzystano proste, klasyczne metody statystyczne, w tym analizę zmian wielkości ruchu turystycznego w poszczególnych latach. Przeprowadzona analiza pozwala wskazać na zdecydowany spadek liczby wizyt wycieczkowców w Gdyni w badanym okresie przy stabilizacji liczby turystów na poziomie 80–90 tys. w ostatnich czterech latach. Jednak ta liczba wynika z faktu wizyt większych cruiserów w ostatnich latach, niż miało to miejsce wcześniej. Peryferyjne w stosunku do głównych bałtyckich tras turystyki morskiej położenie portu w Gdyni i brak znaczących inwestycji w infrastrukturę portową na potrzeby turystyki morskiej prowadzi do stabilizacji wielkości ruchu turystycznego na obecnym poziomie.
    Maritime tourism is one of the fastest growing tourist branches, bringing significant revenue to the cities and ports that develop it. Baltic cruises generates about 20% of all maritime tourist traffic. However, Polish ports, as shown through the example of Gdynia, have a small marketshare. The article presents results of the analysis of changes in the volume of traffic of cruise ships and the number of tourists arriving in Gdynia. The undertaken research is aimed at assessing and indicating the direction of changes in maritime tourist traffic in Gdynia in the years 1997–2016. The subject of the study are changes in the number of visits of cruise ships and tourists in the port of Gdynia. The data for the analysis of the traffic volume of the cruise traffic come from the reports and information from the Port of Gdynia Authority S.A. in Gdynia and cited in the literature. The work used basic statistical methods, including the analysis of changes in the volume of tourist traffic in particular years. It has made it possible to indicate a decisive decrease in the number of visits made by cruisers in Gdynia in the analyzed period, with the number of tourists stabilizing at 80–90 thousand per year in the last four years. However, this number results from the fact that Gdynia had visits of larger cruisers in last years than it was in the previous period. The location of the port in Gdynia and the lack of significant investments in port infrastructure for maritime tourism lead to the stabilization of tourist traffic at the present level.

    Opis:
    Vessel passage speed is one of the parameters describing the vessel traffic stream on a selected waterway. Knowing the probability distribution of vessel passage speeds is essential for modeling vessel traffic streams on a waterway. This article undertakes probabilistic modeling for vessel speeds in restricted areas, where the distribution of the vessel passage time of the waterway section is known. The probabilistic procedure of the inverse random variable is used. Four different cases are considered. First, the probabilistic distribution of the vessel passage speed is given, where the vessel passage time is described by the normal distribution in certain restricted areas. The next three cases present the probabilistic distribution of vessel passage speeds on the Szczecin–Świnoujście fairway, where the vessel passage time is described by the extreme value distribution, the Frèchet distribution and the Weibull distribution.

    Opis:
    This paper evaluates near ship-ship collision situations in the Tagus River Estuary using a simulation model of ship navigation in restricted waters. The simulation model consists of a ship collision avoidance model based on the Artificial Potential Field (APF) method, which has been improved to account for the lateral distribution of traffic along the route, the ship type and length and speed development of the ships along the trajectory. AIS data of ships entering and leaving the port of Lisbon are analysed to obtain the main characteristics of traffic parameters used as input for the traffic simulation model, such as: the routes of the vessels, speed distribution along the routes, traffic density and characteristics of the ships in each route, among others. First, the improved model of ship navigation and the Monte Carlo simulation technique are used to simulate the marine traffic in the Tagus River Estuary. Then, the concept of “ship domain” is used as collision criterion to determine the number of near collisions and the locations where they are most likely to occur. Finally, the simulation results are compared to the ones obtained from raw AIS data to assess the capability of the simulation model for marine traffic risk analysis.

    Opis:
    The Strait of Istanbul, 17 nautical miles long, is one of the main routes of international maritime trade. Connecting the Black Sea countries with other countries of the world, the Strait is the second busiest waterway in the world in terms of international ship traffic. In addition to busy sea traffic, limited geographical conditions also make it difficult to navigational safety. The Strait of Istanbul is the only chokepoint that stands out with the risk of maritime accidents on the primary routes of world maritime trade. This situation poses a risk for both the transiting ships and the city of Istanbul, which has a dense population around it. Some of the accidents that took place in the recent history have caused worldwide concern due to the environmental pollution they cause. Considering the advantages provided by the developing shipbuilding technology and today load capacity of the ships, a disaster that will occur in a possible accident today will cause much greater destruction than in the past. In this direction, it has become a necessity to examine the accident profile in the strait in order to develop effective accident prevention measures and to strengthen the level of navigational safety in the region. In this study, maritime accidents that occurred in the Strait of Istanbul over a 16-year period were discussed in terms of their types and the response time of tugboats to a possible accident was examined.

    Opis:
    Until recently the concept of spatial planning concerned only land areas, chaos prevailing at sea in this scope. Vessel routes were selected by the Master on the principle of “freedom of navigation”. It was similar with the submarine routes of pipelines and cables, wind farm construction zones, excavation of aggregates, or the conduct of any human activity at sea. A systemic approach is introduced and preferred currently, which is to take into consideration the natural conditions and human achievements on one hand, and look ahead on the other, systematising procedural ac-tivities and minimising possible conflicts of interests among potential users of the sea.

    Opis:
    Approaches to the port are usually considered high traffic areas. Not only deep draft vessels pass through this limited manoeuvring space, but also intensive pleasure craft traffic, especially during the summer season. Crossing of both commercial ships and pleasure craft traffic may generate dangerous situations for navigation. The aim of the following article is to present solutions to the aforementioned safety problem. The article focuses on the navigation safety aspects at the Świnoujście seaport entrance. Currently, Świnoujście-Szczecin Port Regulations take only large ships into consideration while specifying the safety passing at this area, at the same time, belittling the presence of small crafts up to 20 m in length. In order to prove the need for change, one should first present the necessary research concerning the evaluation of the safety level of maximum sized ships navigating at the Świnoujście entrance area in the presence or absence of small pleasure crafts. The surveys were conducted on a group of pilots and captains possessing pilot exemption certificates. The research findings clearly show that the traffic of small crafts and large ships should be separated due to safety concerns. Thus, marine traffic engineering solution is suggested in order to eliminate the most plausible dangers.

    Current maritime transportation and shipping is characterized by rapid technological developments effecting the basic concepts of operating ships and even changing traditional paradigms of controlling ships. The e-Navigation concept of the International Maritime Organization (IMO) specifically aims at more comprehensive and reliable support of the human operators on-board and ashore. However, autonomous unmanned ships remote controlled or even autonomously navigating are expected to come soon. In this paper, selected operational aspects of maritime traffic merging conventional and unmanned remote controlled ships in coastal areas are discussed. Furthermore, some preliminary results of experimental simulation studies into a future scenario of maritime traffic are presented and preliminary conclusions in respect to job profiling and training requirements are discussed.

    Opis:
    The aim of this paper is to present an analysis of the main factors influencing negatively Klaipeda Sea Port performance and competitiveness as well as their limiting impact on the development of this transport system entity in general. This case study research is proposing some alternative solutions decreasing negative influences of comparatively declining land transport infrastructure connectivity to the Sea Port hinterland. Analysis of hinterland connectivity is based on the extended gate concept, where a series of terminals and related logistical activities are integrated into a functional single entity. The intensity of real road transport flows on the main connecting road intersections has been evaluated using digital tools with input data from the ArcGIS platform. Also, accessibility to other terminals (at the local, regional and global scale) as well as the terminal is linkage to the regional transport system has been taken into account. One of the objectives of this research was to define objectively the state of traffic flow on the highway connecting Klaipeda sea-port to its hinterland because the road infrastructure was not qualitatively improved for a long period, while the average annual seaport turnover is constantly growing by 6% - 9%. Secondly, it was defined how substantially is possible to decrease the load of road traffic in case of reestablishing of an inland waterway connection between practically the same points of the transport route. Using mathematical modeling of traffic flows is proved that, road transport highway connection in/from the Klaipeda Seaport is loaded substantially and requires systemic improvement (building at least additional lanes in both directions, etc.) to promote further growth of Klaipeda sea-port capacities. The option to apply an additional inland waterway connection allows to decrease the road traffic flow up to 9 – 11% with the possible development of this option, what in its’ turn also decrease the negative influence on the environment.

    Opis:
    Rola pilota jest nieco marginalizowana, mimo, iż jego działalność przekłada się bezpośrednio na zapewnienie bezpieczeństwa żeglugi w portach morskich, ochronę środowiska morskiego, a także minimalizowanie ryzyka wypadków i incydentów morskich. Świadczenie usług pilotowych powierzone zostało prywatnym przedsiębiorcom spełniającym określone kwalifikacje i poddane nadzorowi administracji morskiej. Artykuł ten zawiera odwołanie do orzeczeń Izby Morskiej w Gdyni w sprawie, w której pilot morski przyczynił się do spowodowania wypadku w gdańskim porcie. Analizie poddano również rolę pilota morskiego w zapewnieniu bezpieczeństwa żeglugi w porcie.
    This article deals with the influence of the maritime pilot on safety of navigation. The role of the pilot is somewhat marginalized, although his activity is directly related to ensuring the safety of navigation in sea ports, protection of the marine environment and minimizing the risk of collision with ships and port infrastructure. Pilot services have been entrusted to private entrepreneurs who meet certain legal requirements and are subject to supervision by the maritime administration. The article contains a reference to the decisions of the Maritime Chamber in Gdańsk in a case, in which the maritime pilot contributed to an accident in the port of Gdańsk and the analysis of these decisions in the context of the role of the pilot in the safety of navigation in port.

    Opis:
    The main aim of the article is modelling the operation process of the Baltic Port, Shipping and Ship Traffic and Port Operation Information Critical Infrastructure Network. To achieve this goal it is necessary to define three critical infrastructure networks for a Baltic Sea Region and their operation processes: port critical infrastructure network, shipping critical infrastructure network and ship traffic and port operation information critical infrastructure network. Thus, the concept of networks of three networks, called Baltic Port, Shipping and Ship Traffic and Port Operation Information Critical Infrastructure Network, is introduced. This way, the operation process of network of networks is proposed. To understand this approach, the basic classification and description of interdependencies and interconnections in this network are presented.

    Opis:
    It is proposed the description of interface for VHF/MF/HF for simplification of DSC communication for implementation in the frame of conception developments in GMDSS services, applied to Maritime Mobile Services. This interface is realized within its integration with INS by an appropriate way on the base of common communication protocol for all three DSC communication sub bands in standardized and harmonized format and significantly simplifies the DSC user interface. It is very important for application in Maritime services, including GMDSS services, VTS services and SAR service. Suggested approach for improving DSC communication is based on the three main outputs of e-navigation strategic direction development related to the integration of communication and navigation equipment/systems, including standardized mode of operation. Implementation of the standardization demands to include in this integration the satellite AIS system. The feasibility of the proposal is supported by the existence of relevant IEC standards and IMO documents.

    Opis:
    Shared mental models, measured as similar perceptions and understandings of the components of a work task or an operative environment, is a key characteristic for high performing teams. Identifying and addressing differences in mental models may help enhance teamwork, and can serve as a frame for the improvement of human-centered information and communication systems. This paper has been written as part of the SESAME Straits project, a testbed within the e-Navigation framework. It examines similarities and differences in mental models between Deck Officers working aboard ships and Vessel Traffic Service Officers working ashore. Data was compared the participants´ perception of 12 challenging traffic situations in the Straits of Malacca and Singapore. A total of 189 respondents participated by means of an electronic survey. Findings show that Deck and Vessel Traffic Officers do have a large degree of shared mental models, but that there also are significant differences. In particular, there are large ship-shore differences in perceptions of the impact on local ship traffic on safety and efficiency. The second and third situation of large difference was delayed or reduced availability of port services, and challenging weather conditions. Implications are that future development of ship-shore collaborative systems should specifically explore and address the issue of local ship traffic, and to find ways to integrate information about availability and timing of port services and of difficult weather situations.

    Opis:
    The development of digital technologies, increasing the availability of big data and advanced processing techniques have enabled Statistics Poland to modernise the system for producing road and maritime transport statistics. As a result of the activities undertaken to adopt modern big data technologies and data from sensors, e.g. the Automatic Identification System (AIS) or the e-TOLL electronic toll collection system, new statistics have been obtained and data dissemination has accelerated. In addition, these activities ensure continuity in data production, especially in situations where collecting data from individuals may be difficult (e.g. the COVID-19 epidemic). The primary purpose of this article is to present the innovative TranStat system that enables the production of road and maritime transport statistics based on large volumes of data in order to shape the country's transport policy. The system was developed under the GOSPOSTRATEG programme and implemented by Statistics Poland, the Statistical Office in Szczecin, the Maritime University of Szczecin, and the Cracow University of Technology. The study presents the most important aspects of the TranStat system, i.e. the characteristics of data sources, the description of functional subsystems, assumptions of the developed models and result data for traffic statistics, transport performance and exhaust emissions calculations for both types of transport. This study also provides information on smart forms implemented by Polish official statistics, reducing the burden on respondents and the costs of surveys.
    Rozwój technologii cyfrowych, zwiększenie dostępności danych typu big data oraz zaawansowane techniki ich przetwarzania umożliwiły polskiej statystyce publicznej unowocześnienie systemu produkcji statystyk transportu drogowego i morskiego. Dzięki działaniom podjętym w celu adaptacji nowoczesnych technologii big data i danych sensorycznych, m.in. z systemu automatycznej identyfikacji statków AIS (ang. Automatic Identification System) czy elektronicznego systemu poboru opłat e-TOLL, uzyskano nowe statystyki oraz przyspieszono proces udostępniania danych. Ponadto działania te zapewniają ciągłość w obszarze produkcji danych, szczególnie w sytuacji, gdy zbieranie danych od respondentów może być utrudnione (np. podczas epidemii COVID-19). Głównym celem niniejszego artykułu jest zaprezentowanie innowacyjnego, opracowanego w ramach programu GOSPOSTRATEG systemu TranStat, który umożliwia produkcję statystyk transportu drogowego i morskiego z wykorzystaniem wielkich wolumenów danych i tym samym służy kształtowaniu polityki transportowej kraju. Projekt TranStat został zrealizowany przez Główny Urząd Statystyczny, Urząd Statystyczny w Szczecinie, Politechnikę Morską w Szczecinie oraz Politechnikę Krakowską. W pracy przedstawiono najważniejsze cechy systemu TranStat – scharakteryzowano źródła danych, opisano podsystemy funkcjonalne i założenia opracowanych modeli oraz podano informacje wynikowe dla statystyk natężenia ruchu, pracy przewozowej i emisji zanieczyszczeń dla obu rodzajów transportu. Omówiono też inteligentne formularze wdrożone przez statystykę publiczną, mniej obciążające dla respondentów i umożliwiające redukcję kosztów badań.
