Opis:
This paper presents a functional model of river-sea ships (shortly called: SRM) operating in European system of transport corridors. It is composed of two parts: Part I contains a descriptive model of functioning the SRM fleet with taking into account various shipping tasks as well as impact factors (external and internal factors, limitations and criteria). Also, a mathematical model of functioning the SRM fleet, including choice of relevant economic criteria (e.g. profit maximization, capital return period minimization etc), is presented. Results achieved on the basis of the functional model are presented in Part II of the paper.

Opis:
This paper presents continuation of the research on the functional model of river-sea ships operating in European system of transport corridors. It deals with a set of methods of determination of design assumptions for river-sea ships. Relevant calculations were performed on the basis of a future network of European routes for operating the river-sea ships within EU system of water transport corridors, in which rates of cargo flows and lengths of particular routes as well as their mathematical model were taken into account. In consequence, technical assumptions for designing the fleet of river-sea ships to be operated in European system of water transport corridors, were obtained.

Opis:
This paper presents a description and the results of experimental studies of the deformation, friction and structural damping occurring in foundation bolted joints of propulsion plant components and auxiliary machinery that is rigidly mounted on sea-going ships. The rigid mounting of these devices to the ships’ structural foundations can be implemented in a traditional way, i.e. on chocks made of metal (usually of steel), or in a modern way, i.e. on chocks cast of resin, specially designed for this purpose. The main goal of this study is to perform a comparative analysis of these two solutions and to give a scientific explanation for why chocks cast of resin perform better in machinery seatings than the steel chocks traditionally used for this purpose. The paper consists of two parts. Part I presents the details of the rigid mountings of machinery to the foundations, and contains the results of experimental studies performed on a model of a foundation bolted joint with a traditional steel chock. Part II contains the results of similar studies carried out for a model of a bolted joint with a modern chock cast of resin. Next, a comparative analysis and evaluation of the results obtained for both investigated bolted joints was carried out, and conclusions were formulated to highlight important aspects of the problem from the point of view of science and engineering practice.

This article is Part II of the paper containing a description and results of the experimental studies of the deformations, friction processes and structural damping that occur in the foundation bolted joints of propulsion plant components and auxiliary machinery installed on sea-going ships. Part I of this research work presents an analysis of the rigid mountings of machines and devices to the foundations on steel or resin chocks, and explains the need to carry out relevant research in this area. It also presents the description and results of experimental studies carried out for a foundation bolted joint with a conventionally used steel chock. Part II (this article) contains a description and results of similar studies carried out for a foundation bolted joint with a modern chock – cast from epoxy resin compound (EPY), specially developed for this purpose. Then, a comparative analysis of the results obtained for both bolted joints in question was made and the foundation chocks of the poured-in-place resin compound were demonstrated to better fulfill their technical tasks than the steel chocks traditionally used for this purpose.

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:
This article presents some of the problems which occur in the course of transforming signals of work process parameters in the testing of internal combustion engines, when power is supplied to a measuring appliance from a shipboard system under certain conditions and on the same measuring path. It characterizes the interference which has an influence on the results of measurements of pressure course in a diagnostics test conducted under marine conditions. In order to identify and to eliminate interference the wavelet analysis of signals of pressure in cylinders of internal combustion engines was carried out. As a result of the analyses it was found that the sources of interference are: electricity grid, electrical power equipment, indicator channels and valves, as well as sensors and measuring sets.
W artykule przedstawiono problemy występujące w czasie przetwarzania sygnałów parametrów procesów roboczych w trakcie badań silników spalinowych, przy zasilaniu aparatury pomiarowej z sieci okrętowej, w określonych warunkach i tym samym torze pomiarowym. Scharakteryzowano zakłócenia mające wpływ na wyniki pomiarów przebiegu ciśnienia w badaniach diagnostycznych prowadzonych w warunkach eksploatacji statków morskich. W celu identyfikacji, a następnie eliminacji zakłóceń zastosowano analizę falkową sygnałów ciśnienia w cylindrach silników spalinowych. W wyniku wykonanych analiz przebiegów czasowych i widmowych oraz ich dekompozycji falkowych ustalono, że źródłem zakłóceń są: sieć zasilająca i urządzenia energetyczne, kanały i zawory indykatorowe oraz czujniki i układy pomiarowe.

Opis:
Po wielu latach od przyjęcia w 1982 roku konwencji o prawie morza, u progu XXI wieku zyskała ona niemal pełną i powszechną aprobatę społeczności międzynarodowej. Ciągle jednak można dostrzec liczne przykłady rozbieżnych interpretacji jej postanowień. Jest to doskonale widoczne na przykładzie ośmiu państw bałtyckich, które ratyfikowały konwencję, a jednocześnie niektóre z nich utrzymują prawo krajowe pozostające w wyraźnej sprzeczności z jej normami. Dotyczy to szczególnie kwestii „reglamentowania” przepływu okrętów obcej bandery przez morze terytorialne i cieśniny międzynarodowe (poprzez wymogi notyfikacji, korzystania tylko z wyznaczonych szlaków morskich i uzyskania zezwolenia). W artykule podjęto ten problem, poddając analizie rozwiązania przyjęte we wszystkich państwach bałtyckich i NATO.
At the beginning of the 21st century, many years after the convention on the law of the sea was adopted in 1982, it has gained almost universal recognition of the international community. Still examples of different interpretations of its clauses can be noticed. This is clearly visible in the case of the eight Baltic states, which ratified the convention, but some of them have still in effect the national law which is in contradiction to some clauses of the convention. This pertains mainly to the issue of „rationing” the passage of ships, displaying foreign ensign, through the territorial sea or international straits (by requiring notification, using assigned waterways and obtaining permission). The paper deals with this problem, analyzing the solutions adopted in all the Baltic and NATO countries.

Opis:
Main problem for scheduling vessel transit voyages through the Northern Sea Route is the difficulty in predicting distribution of ice boundaries in regions that cannot be overcome by individual ice classes of vessels. Scheduling of voyage is related to speed that vessels can develop and moment of time when vessels will be able to commence and complete passage safely through areas that are main obstacle and are blocking longest transit passage through the Northern Sea Route. This applies to voyages carried out by vessels navigating on their own and with support of icebreakers. Additional problem is lack of consistency of content of maps of ice cover, which can be used for vessels voyage planning through areas where ice cover occurs. Results of this research on influence of uncertain information related with time window of conditions favorable for navigation of vessels of different ice classes on schedule of theirs voyage on example of summer navigation season 2017 are presented in this work.

Opis:
This paper is an extension of work originally presented in 2019 EUROPEAN NAVIGATION CONFERENCE (ENC) [4]. The paper has described the important role of the Stockholm Agreement in safety of the Ro-Ro/Passenger ships in the north European waters. The present work describes the way in which we can improve the safety in strong chance of destruction of ship at sea. All results are generalized for a given group of ships. The specific construction of the RO-RO/ Passenger ships, being characterized by flat vehicle decks which are practically open, un-subdivided, and additional passenger accommodation space, with ramp fitted astern and in some cases in fore or side of the ship, giving access to cars, trucks and trailers, or specific trains which remain on board in their laden state, has resulted in international regulation requiring, amongst other things, strengthening the damage stability requirements for this type of ships. The more stringent damage stability criteria has been adopted on a regional basis by northern European countries as STOCKHOLM Agreement, in 1996. The paper concerns an analyze of damage stability calculations results in compliance with the STOCKHOLM Agreement, when the Ro-Ro/ Passenger ship is fully loaded, with maximum Deadweight (DWT) and maximum draught, or partly loaded, with reduced DWT, and occurs Minor or Major penetration of destroyed compartments.

Opis:
Modern industries often attempt to implement innovations that have a disruptive potential. In shipping, this included a largely unsuccessful introduction of nuclear propulsion in late 20th century, among other concepts. Nowadays, introduction of increased autonomy is being associated with prospects of various industry-wide benefits, but is also burdened with serious obstacles. The objective of this study is to investigate reasons behind the failure of nuclear-powered merchant ships introduction and whether lessons learnt from it can be applied to the prospective implementation of autonomous merchant ships. It advocates that three aspects of maritime technology are crucial for its successful implementation: perceived level of safety, economical feasibility, and legal setup.
