    Opis:
    The use of the Automatic Identification System (AIS) devices for ensuring the safety of navigation and the errors occurring when using AIS equipment have been the focus of a number of research studies. The users of AIS equipment installed onboard sea-going vessels are required to familiar with the proper use of the devices and potential errors that may occur. A significant problem revealed in this study is the lack of understanding of potential error sources and the necessity to eliminate such errors prior to transmission of the AIS data message reading of the errors and failure to update the data processed by the AIS system. This results in a hypothesis on the insufficient training of seafarers and their familiarisation with the AIS devices and errors. This research is aimed at increasing the safety of navigation in the Adriatic Sea, as well as other seas, i.e. better accident prevention and protection of human life and material property at sea. The results produced by the research are used as an input for creating a model for enhancing the safety of navigation when using the AIS, through additional training of the seafarers.

    Opis:
    The growing demand for transportation has brought even larger quantities of traffic in spatially limited port areas. Considering a diverse traffic mix, infrastructural overcapacity and busy schedule, port communities have started to face possible degradation of safety and environmental standards. To mitigate these problems, a number of different monitoring solutions of marine environment were deployed. Since conventional environmental and traffic data gathering by physical monitoring and sampling was logistically complicated and inefficient in time and resources, different approaches had to be considered. With the rise of accessible Internet of Things (IoT) technology some ports already installed smart monitoring devices such as smart buoys. The goal of this paper is to examine the concept and benefits of an automated smart buoy as a cost effective, easy to install device capable of real-time remote information sharing. Furthermore, the design and operational processes of existing automated smart buoy will be presented, along with solutions for tackling navigational safety and environmental problems.

    Opis:
    Strong expansion of cruise ships traffic and cruising destinations in the Adriatic makes the region ideal for cruise ships routing analysis. The aim of this paper is to detect real cruise ships traffic movement in order to understand how present cruise ships routes are navigationally and environmentally sustainable and safe. Cruise ships characteristic operational demand and navigational routine in relation with regions indented coast line with high level of environmentally preserved areas in landscape of high national value, emphasise importance of real cruise ships routing awareness. The research is based on one year cruise ships traffic monitoring and routes analysis in the Central Adriatic East coast. The results offer detail insight of cruise ships navigational routines in navigationally less defined area that has not been frequent cruising region before. Cruise ships routes comparison is carried out between North Adriatic region, which is well defined with traffic separation schemes and navigational aids and less defined Central and South Adriatic regions. The results show that principle of cruise ships routing differ from standard maritime practice and that operational demand for attractive cruising and passenger experience bring cruise ships close to shores in various demanding navigational situations. That routing practice does not meet criteria of sustainability as it often present high navigational, safety and environmental risk.

    Opis:
    Ship manoeuvrability is a wide term which consist of number of various parameters. Knowing the influence of these parameters on ship manoeuvrability is a first condition to ensure and maintain safe navigation. However, many of these parameters are external forces and, in some cases, cannot be calculated and prediction may be complicated. Analysing the influence of external forces can give as an insight into ship manoeuvrability when such external force occurs. The main purpose of this paper is to analyse the influence of wind on ship manoeuvrability. The best way to make such analysis is during turning circle because in this case wind acts in all 360°. Analysis is made using empirical equations and in situ with the real vessel. The results provide the better understanding of vessel trajectory and show that in some cases vessel may respond in unexpected manner.

    Opis:
    A complex of ice cover characteristics and the season of the year were considered in relation to vessel route planning in ice-covered areas on the NSR. The criteria for navigation in ice - both year-round and seasonal were analyzed. The analysis of the experts knowledge, dissipated in the literature, allowed to identify some rules of route planning in ice-covered areas. The most important processes from the navigation point of view are the development and disintegration of ice, the formation and disintegration of fast ice and behavior of the ice massifs and polynyas. The optimal route is selected on basis of available analysis and forecast maps of ice conditions and ice class, draught and seaworthiness of the vessel. The boundary of the ice indicates areas accessible to vessels without ice class. Areas with a concentration of ice from 0 to 6/10 are used for navigation of vessels of different ice classes. Areas of concentration of ice from 7/10 up are eligible for navigation for icebreakers and vessels with a high ice class with the assistance of icebreakers. These rules were collected in the decision tree. Following such developed decision-making model the master of the vessel may take decision independently by accepting grading criteria of priorities resulting from his knowledge, experience and the circumstances of navigation. Formalized form of decision making model reduces risk of the "human factor" in the decision and thereby help improve the safety of maritime transport.

    Opis:
    The priority of the maritime transport operation is a high level of security, which must be constantly monitored by shipowners with a security management system. The origin of the International Code for the Management of Safe Ship Operations and Pollution Prevention and the revised guidelines for the administration of the ISM Code by administrations, the first formal mandatory standard for safety management and pollution prevention goes back to the early 1980s. Arrangement of safe ship management and operation and consequent minimization of errors human being by far the most common cause of marine disasters is its main. The shipowner's and ship's certification procedure for the Safety Management System (SMS) is in line with Regulation (EC) No 336/2006 [1] of the European Parliament and the Council of Europe of 15 February 2006 on the implementation of the ISM Code in the Community, together with the Commission's amendment European Union of June 16, 2008. The documentation contains a developed Safety Management System adapted to the conditions of a given shipowner. All elements of the system must be documented, and, above all, the duties must be described in the organizational structures. Documentation must indicate how management supervises activities at various levels, employee participation and individual management representatives in individual processes, and how the safety management system is constantly improved. The shipowner maintains a security management system in line with the requirements of the Code and complies with the requirements of the certification system. The amount of information and the speed of changes taking place in the environment makes it necessary to introduce a system of information management and channels of their flow not only within the organization, but also in communication with third parties. Proper management of information resources increases the efficiency and effectiveness of the system. In the publication, the possibility of a formalized description of information flow in a well-functioning shipowner's safety management system.

    Opis:
    Autonomous and remotely controlled ships present new types of human factor challenges. An investigation of the underlying human factors in such operations is therefore necessary to mitigate safety hazards while improving operational efficiency. More tests are needed to identify operators’ levels of control, workload and stress. The aim of this study is to assess how increases in mental workload influence the stress levels of Shore Control Centre (SCC) operators during remote ship operations. Nine experiments were performed to investigate the stress levels of SCC operators during human-human and human-machine interactions. Data on the brain signals of human operators were collected directly by electroencephalography (EEG) and subjectively by the NASA task load index (TLX). The results show that the beta and gamma band powers of the EEG recordings were highly correlated with subjective levels of workload and stress during remote ship operations. They also show that there was a significant change in stress levels when workload increased, when ships were operating in harsh weather, and when the number of ships each SCC operator is responsible for was increased. Furthermore, no significant change in stress was identified when SCC operators established very high frequency (VHF) communication or when there was a risk of accident.

    Opis:
    The Electronic Chart Display and Information System (ECDIS) became the central navigational tool on modern ships. The system comprises numerous navigational and other components, each of them with its limitations and reliability. Due to ECDIS's revolutionary features, navigators are tempted to place excessive reliance on the system. Such reliance on it as a sole navigational aid is undoubtedly a problematic issue. The proposed paper is a segment of a systematically carried out research among ECDIS stakeholders. ECDIS EHO (Experience, Handling, and Opinion) research aims through research activities based on a user-centred approach to develop and improve the educational framework. The overreliance on the ECDIS system motivated the proposed research, which focused on system users' opinions and practice regarding confirmation of the accuracy of information displayed on ECDIS, particularly concerning positional sensors. Analysis of answers collected by the ECDIS EHO questionnaire represents a backbone of the research supported by previous achievements. The answers have been categorized and discussed, revealing certain worrying aspects referring to the system's positional error experienced by users. Furthermore, preferred methods of cross-checking ECDIS information have been identified and have differed among respondents based on their rank on board. Additionally, answers indicate certain doubts between users’ interpretation of the best confirmation method and the actual selection of the used method. The importance of cross-checking navigational data in avoiding overreliance and maintaining situational awareness has been presented in the conclusion chapter and the proposal for further work.
