Opis:
In the paper the Author describes the general concept of a Universal Maritime Data Model (UMDM) a common representation of all data objects and relationships occurring in the maritime domain. Implementation of IMO's e-Navigation strategy leads to a larger variety and higher volume of information and increased information exchange due to globalization. Consequently there is a need to handle information more effectively in a standardized way. The first step towards a common data structure is to define the meaning of each and every item in the data structure and the relationships among the items. This is done so that implementers of the data structure have common understanding of items. The means to do this is with a data model. At this stage, the data model, like the system architecture needs only to be described in the most general of terms. An example of how a UMDM could be implemented has been provided by the IHO with its S-100 model. In January 2010, IHO introduced a new data model known as S-100 - the Universal Hydrographic Data Model (UHDM). This international standard has been developed by the IHO over the last ten years in consultation with a wide range of stakeholders, including key ECDIS and navigation equipment manufactures. The purpose of S-100 is to provide framework architecture for a contemporary standard for the exchange of hydrographic andrelated maritime data. As the UHDM is aligned with ISO 19100 it will enable the exchange of hydrographic, chart and other maritime data and information together with geospatial data from other domains. The use of ISO 19100-based data standards enables interoperability between geospatial data sets from different domains and could therefore be appropriate for many of the datasets envisaged for data exchange in e-Navigation.

Opis:
In the paper the author presents overview of the meridian distance approximations. He would like to find the answer for the question what is actually the distance from the equator to the pole ‐the polar distance. In spite of appearances this is not such a simple question. The problem of determining the polar distance is a great opportunity to demonstrate the multitude of possible solutions in common use. At the beginning of the paper the author discusses some approximations and a few exact expressions (infinite sums) to calculate perimeter and quadrant of an ellipse, he presents convenient measurement units of the distance on the surface of the Earth, existing methods for the solution of the great circle and great elliptic sailing, and in the end he analyses and compares geodetic formulas for the meridian arc length.

Opis:
Navigational charts are essential tools for marine navigation. But how accurate are the navigational charts that we use when going sailing? Do we really know how much faith can be placed in them? All charts, whether paper or electronic, contain data, which varies in quality due to the age and accuracy of individual surveys. In general, remote areas away from shipping routes tend to be less well surveyed, and less frequently, while areas of high commercial traffic are re-surveyed frequently to very high levels of accuracy, particularly where under-keel clearances are small. It is quite accurate to consider a chart as a jigsaw of individual surveys pieced together to form a single image. Having the necessary skills to determine how much confidence should be placed in the surveys, which combine to form a chart, should be a requirement for any sailor venturing into unfamiliar waters. When the International Hydrographic Organization (IHO) developed the S-57 standard for Electronic Navigational Charts (ENCs), this problem was recognized and it was decided that the quality of survey data used to compile ENCs had to be encoded within a composite data quality indicator ‘Category of Zone of Confidence’ (CATZOC) to assist seafarers in assessing hydrographic survey data and the associated level of risk of navigating in a particular area. According to IHO S-67, the accuracy of Electronic Navigational Charts is not impressive and leaves much to be desired. The author discusses these apparent shortcomings of ENCs and present erroneous approaches to this problem, so common in the seafaring community.

Opis:
Navigational charts are a basic source of information for seafarers. But how accurate and reliable are they? How much trust and confidence can be put in them? Unfortunately, the answer is not so simple; it is far more complicated than merely saying that one chart is accurate and reliable while another is not. However, any seafarer navigating in unfamiliar waters should have the necessary skills. It is a great challenge – some may say an impossibility – to keep the thousands of navigational charts up to date. But exactly how out of date, how inaccurate, are the chart data? Chart users will have a better idea now that the Hydrographic Office is gradually implementing a new chart feature called the Zone of Confidence (ZOC) box which replaces the Source Diagram that is currently in use on large-scale charts. Source Diagrams, and now the improved ZOCs, assist seafarers in assessing hydrographic survey data and the associated levels of risk of navigating in a particular area. According to the new edition of the International Hydrographic Organization (IHO) specifications, S-4 navigational charts will provide more information on ZOCs. The current paper discusses these new regulations.

In the paper the Author tries to present the background to e-Navigation and its definition, the key elements which in the vision for e-Navigation were covered and the IMO's strength as the co-ordinator of e-Navigation, including strategy implementation plan. The underlying important principles were stated, together with the need to take user needs into account. Recent presentations and comments showed just how ambiguous the term „users? can be in the context of e-Navigation. This led to a more in depth review of the components of the IMO Strategy Implementation Plan. The author tries to answer the question of whether these assumptions, decisions and actions taken were appropriate and sufficient. The author asks the simple question whether the mere adoption and introduction of the concept of e-Navigation in life will be enough to meet all the challenges of the twenty-first century.

In the course of developing the publication "Recommendations on usage of ECDIS and preventing incidents" [19] by members of the Oil Companies International Marine Forum (OCIMF), they have identified the importance of sharing information on a malfunction of an ECDIS. The problem was discussed in the forum of the International Maritime Organization (IMO). As a consequence, there was a necessity to modify the IMO’s ECDIS – Guidance for Good Practice. This guidance is intended to assist smooth implementation of ECDIS and its ongoing safe and effective use on board ships. In the new version of this document (second revision), new important terms appear, such as: type approval authority (TAA), type approval certificate (TAC), letter of acceptance (LOA), declaration of conformity (DOC). In this article, the author tries to present the problem and describe the actions taken by the appropriate IMO bodies.

This paper presents draft guidelines on the display of navigation-related information received by communications equipment elaborated by the International Maritime Organization (IMO) [3]. It aims mainly to ensure that information is displayed in an efficient, reliable and consistent format, in a manner that is easily and accurately interpreted to support decision-making process. These guidelines supplement resolution MSC.191(79) Performance standards for the presentation of navigation-related information on shipborne navigational displays [7] in regard to the presentation of navigation information received via communication equipment. The use of these guidelines will ensure that navigation information received via communications equipment is displayed in a harmonized manner on the ships’ navigational bridge. The availability of electronic data that enhances the safe and efficient navigation of ships necessitates that shipborne systems capable of presenting this information to the user should do so in a harmonized and readily assimilated way.

The article discusses the concept of time in navigation, especially in marine navigation, as well as selected time measures, among others: Greenwich Mean Time (GMT), Universal Time Coordinated (UTC), International Atomic Time TAI (Temps Atomique International), GPST (Global Positioning System Time) eLoran Time and interrelation between these measures. Understanding how time is involved in navigation, and using it, is one of the navigator's most important duties. Nowadays we have satellite navigation to help us know where we are. These satellites contain several very precise and accurate clocks, because time and location are completely and totally inter-related in satellite navigation. There is growing interest internationally concerning the vulnerability Global Navigation Satellite Systems (GNSS) to natural and man-made interference, plus the jamming and spoofing of their transmissions. These vulnerabilities have led to a demand for sources of resilient PNT (Positioning, Navigation and Timing) [16], including a robust means of distributing precise time nationally and internationally.

Opis:
Traditional marine navigation methods are replaced by new solutions that use computers. Electronic Chart Display and Information Systems (ECDIS) are mandatory almost on every vessel [24],[25]. ECDIS not complying with regulations is an existing problem and a hazard for seafarers and the marine environment. But unfortunately, there is a deficit or even lack of procedures for checking whether ECDIS meets related performance standards. Regulatory bodies of the maritime industry are now contemplating how to tackle this blunder [1]. SOLAS regulations V/18 and V/19 [24], requires that in order to achieve chart carriage requirements (in terms of SOLAS Convention), the ECDIS equipment must conform to the relevant IMO performance standards. ECDIS units on board of the ships are required to comply with one of three performance standards (either IMO resolution A.817(19) [18], as amended [19],[20], or resolution MSC.232(82)) [21], or resolution MSC.530(106) [23], depending on the date of their installation. In this article, the author tries to explain the differences in these three documents. Along with technological progress, the equipment becomes more and more advanced and technologically sophisticated. This applies to both hardware, software and databases. ECDIS software developers should use the right tools, including incorporate automated self-tests into their products and shipping companies should employ maintenance strategies to improve ECDIS compliance [1], taking into account that time is running quickly.

This paper presents the consequences resulting from the guidelines on the display of navigation-related information elaborated by the IMO, related to ECDIS, as part of S-Mode proposal in the implementation process of e-Navigation concept. The idea to develop standard icons to control the chart display functions in ECDIS is discussed. The use of these icons will ensure that navigation information presented on ECDIS screen will be displayed in a harmonized manner on the ships’ navigational bridge. Today many function-related icons vary across different electronic chart systems and between producers. The paper provides information on icons, symbols and abbreviations that required standardization. It was necessary to develop standard icons whose consistency will allow easy and intuitive use of user interfaces of different navigation systems.

In the paper the authors attempt to present the computational problem related to the navigational algorithm (meridian arc formula) implemented in the software applied in marine navigation electronic devices and systems, such as GNSS (GPS, GLONASS, Galileo), AIS, ECDIS/ECS, and other marine GIS. From the early days of the development of the basic navigational software built into satellite navigational receivers, it has been noted that for the sake of simplicity and a number of other reasons, this navigational software is often based on the simple methods of limited accuracy. It is surprising that even nowadays the use of navigational software is still used in a loose manner, sometimes ignoring basic computational principles and adopting oversimplified assumptions and errors such as the wrong combination of spherical and ellipsoidal calculations in different steps of the solution of a particular sailing problem. The lack of official standardization on both the ‘accuracy required’ and the equivalent ‘methods employed’, in conjunction to the ‘black box solutions’ provided by GNSS navigational receivers and navigational systems (ECDIS and ECS) suggest the necessity of a thorough examination of the issue of sailing calculations for navigational systems and GNSS receivers.

Opis:
With change being the only thing that is constant, modern world is undergoing a disruptive change to many aspects of everyday life. Covering 70% of our planet, oceans and industries connected with them are of no exception. The apparent drive towards autonomization in shipping will not only change the way vessels are navigated, but will affect virtually all services needed for the vessels to be navigated. These include not only the design of ships themselves, training of their crews, remote supervision of onboard processes, but also the extremely important - yet not always appreciated - domain that allows for a safe navigation: maritime hydrography. This paper discusses some insights on how the autonomous vessels and future hydrographers may benefit from each other.

Opis:
The paper presents the usage of mathematical theory of evidence in maritime and offshore applications. This paper brings together a collection of some research on the Dempster–Shafer theory of belief functions. By bridging fuzzy logic and probabilistic reasoning, the theory of belief functions has become a primary tool for knowledge representation and uncertainty reasoning in expert systems. This paper can serve as the authoritative reference in the field of evidential reasoning and an important archival reference in a wide range of areas including uncertainty reasoning in artificial intelligence and decision making in maritime and offshore applications, in management, engineering and transport, in marine shipping, coastal management, navigation, surveillance, monitoring and observation. In particular the paper describes uncertainty reasoning approaches to decision making in maritime and offshore applications, possible applications in safety-based assessment, Coastal Management Expert System, mathematical theory of evidence in marine navigation, the optimisation problem of monitoring stations distribution and finally the facility location and location science.

Opis:
Global Navigation Satellite Systems (GNSS) more and more affect many areas of human activity in the world. Every day human activity around the world depends upon satellite systems for positioning, navigation and timing. As these systems are commonly used further efforts must be made to make GNSS more immune to on occurring more and more frequently incidents of jamming and spoofing. It seems that eLoran system is currently the best the technical and scientific solution to allowing for effective protection of the Global Navigation Satellite Systems. Last year the authors presented eLoran system as a potential tool for transmission of the national time signal [Curry et al., 2017]. This time the authors present abilities of additional use of the eLoran as a back-up system for GNSS.
Globalne systemy nawigacji satelitarnej (GNSS) coraz bardziej wpływają na wiele obszarów ludzkiej działalności na świecie. Każdego dnia działalność człowieka na całym świecie zależy od satelitarnych systemów pozycyjnych. Ponieważ systemy te są powszechnie używane, należy podjąć dalsze wysiłki, aby uczynić GNSS bardziej odpornym na coraz częstsze przypadki zagłuszania i podszywania się. Wydaje się, że system eLoran jest obecnie najlepszym technicznym i naukowym rozwiązaniem umożliwiającym skuteczną ochronę globalnych systemów nawigacji satelitarnej. W ubiegłym roku autorzy przedstawili system eLoran jako potencjalne narzędzie do transmisji krajowego sygnału czasu [Curry i in., 2017]. Tym razem autorzy prezentują możliwości dodatkowego wykorzystania systemu eLoran jako systemu rezerwowego dla GNSS.

Opis:
In this paper, two indexes for own ship risk collision assessment in the restricted water are proposed. The first one concerns the collision threats for ships. The second one describes threats that are generated by human error. It is carried out dynamically with accordance to changes in time. To realize the main aim of the paper, the definition of the extended domain of the ship is introduced. Furthermore, the rules to determine the indexes and range of their values are developed. Finally, a comprehensive model and its potential application are presented. There are some important things to take into account during the model development: the interface, the levels and type of the output information, the type and accuracy of the information about the position and movement dynamics of the particular ships. It gives the opportunity to consider the different operation levels. In addition, it also allows us to take into account the different levels of measurement and the collision risk warnings. This approach can be helpful for both the VTS operator and OOW, the ship’s navigator, as the tool to support the safe navigation in restricted water.

Safety, along with the issue of security, is the most substantial and critical issue to any society and nation of the mankind. The fact that human elements contribute dominantly, in particular, to the transportation – marine, air and road traffic – accidents requires not only the technical approaches, but also cultural configuration inherent to the accidents. This paper tries to incorporate Hofstede’s dimensions of national culture to identify possible interaction with accidents. It will be of help to figure out the need to consider the aspect of national culture to be efficient in dealing with policies for safer communities and nations.

Opis:
The paper presents a proposal of a method for the computation of ship’s deck elevation at any time and location on-board. The need for such a computation results from an interaction between a ship and cargo being loaded or discharged by a gantry in port, in terms of heeling and rolling of the vessel. The main purpose of such modeling is the need for improvement of gantry control with regard to faster operations thanks to more accurate estimation of level and moment of cargo release from a gantry hook or spreader. The study may be the contribution to the development of gantry control systems in sea ports.
W artykule przedstawiono propozycję metody obliczania chwilowego wzniosu pokładu statku podczas operacji ładunkowych w porcie. Potrzeba prowadzenia takich obliczeń wynika ze wzajemnego oddziaływania ładowanego ładunku na statek i odpowiednio – statku na proces załadunku. Statek doznaje bowiem zmiennego w czasie przechyłu wskutek umieszczenia na pokładzie bądź w ładowni dowolnej masy, np. kontenera. Zasadniczym celem opisywanych obliczeń jest poprawa dokładności sterowania suwnicą kontenerową poprzez wyznaczenie chwilowego poziomu pokładu w miejscu przeznaczenia każdego ładowanego kontenera i dalej – precyzyjne określenie wysokości i momentu ustawienia kontenera. Przeprowadzone badania mogą się przyczynić do rozwoju systemu sterowania suwnicami w portach morskich.
