Opis:: A significant increase in demand for navigation support systems called Onboard Routing Systems (ORS) can be observed in the World’s merchant fleet. ORS is a navigation-support system that enables route programming to warn of dangers and navigation constraints and determine the required route-safety level directly onboard the vessel. In this article, an attempt to analyze and compare two ORS systems has been made: the Ship Performance Optimization System (SPOS), by the Meteo Consult Group; and the Bon Voyage system by Applied Weather Technologies (AWT). Individual items, methods, and criteria of both systems for optimization and weather forecasting models utilized have been compared. Particular attention has been paid to the usefulness of the systems regarding the problem of identification and avoidance of hazards such as tropical cyclones and wave resonance. Ergonomics of both systems has also been compared.

Opis:: This paper presents the methodology of constructing a collision avoidance plot "ship – tropical cyclone". The computational algorithm and its testing results are presented. The tests make use of information from the voyage of the ship "Diana" and weather reports and forecasts on the real tropical cyclone Bill, which moved in August 2009 across the North Atlantic.

Opis:: It is well known that Weather Routing is one of the effective ship operation methods to reduce fuel consumption and many studies have been conducted to develop the effective calculation methods. However, most studies were performed focusing on the ocean going ships, and there were few studies made for coastal ships. The authors propose a minimum fuel route calculation method for coastal ships that use the precise forecasted environmental data and the propulsion performance data of the ship on actual seas. In the proposed method, we use the Dijkstra’s algorithm to calculate an optimum minimum fuel route suitable for coastal ships. Simulation study was carried out to evaluate the effectiveness of the proposed method using two coastal ships. As the result of study, the authors confirmed that the proposed calculation method is effective for fuel consumption reduction and is applicable for the operation of coastal merchant ships.

Opis:: Based upon the true voyages various methods of avoidance maneuver determination in ship - cyclone encounter situations were presented. The goal was to find the economically optimal solution (minimum fuel consumption, maintaining the voyage schedule) while at the same time not to exceed an acceptable weather risk level.

Opis:: The paper presents a new weather routing solution fully supporting multicriteria optimisation process of route finding. The solution incorporates two multicriteria optimisation methods, namely multicriteria evolutionary algorithm (SPEA) and multicriteria ranking method (Fuzzy TOPSIS). The paper focuses on presenting the proposed multicriteria evolutionary weather routing algorithm (MEWRA). Furthermore, it includes some experiment results together with a short description of the assumed ship model.

Opis:: An example is shown of the 1-2-3 rule application for calculations to determine a route avoiding tropical cyclones. The dynamic programming used is based on regularly received weather reports containing present and forecast data on tropical cyclones. The results were compared with the post factum calculated route which utilized only weather analyses concerning the relevant moments of the voyage and with routes calculated using the cyclone fuzzy domain as an area dangerous to navigation. The calculations were made in the evolutionary algorithms environment.

Opis:: The main purpose of present paper aims at the establishment of a numerical model for solving the nonlinear water wave problems. The model is based on the Navier-Stokes equations with the consideration of a free-surface through the streamfunction-vorticity formulation. The main advantage of the streamfunction-vorticity formulation is that pressure field can be eliminated from the Navier-Stokes equations. To demonstrate the model feasibility, the present studies are first concentrated on problems including the collision of two solitary waves with different amplitudes, and the overtaking collision of two solitary waves. Then, the model is also applied to a solitary wave passes over the submerged obstacle in a viscous fluid. Finally, the application of present study is also to simulate the generation of solitary waves by underwater moving object. All examples give very promising results, those applications reveal that present formulation is a very powerful approach to simulate the fully nonlinear water wave problems.

Opis:: Comprehensive climatology allows to specify not only the structure of the weather conditions, meaning the frequency of particular individuals, but also frequency of “favorable” or “unfavorable” weather, for example, for shipping and port operation. Comparison of “favorable” or “unfavorable” frequency of the weather types in Świnoujście have revealed that in the first decade of the twenty-first century, there was less of the latter than in the years 1971–1980. “Unfavorable” weather are primarily associated with the influx of air masses from northern and eastern sector, although there are among them also the western sector.

Opis:: The article deals with the problem of ship’s ocean route programming. For masters during planning the ocean most convenient route lots of factors are very important such as among others: current, forecast weather, criteria and restriction, speed and fuel characteristic of ships on waves and wind and so on. These elements when are properly identify and adopted allow the master for making an effective ship’s course and speed decision. The aim of research is to show how the SPOS system is treated during the ocean’s ship route. 39 captains of PŻM ships during the year of 2014 answered on 9 questions of questionnaire which were concerned the degree of utilization of SPOS (Ship Performance Optimization System) during the operation of their ships. All the masters confirmed that they use of SPOS system as a browser weather, while only 25.6% of masters confirmed that they also use the SPOS system as a tool in planning the route. They also repeatedly pointed out, however, that SPOS has some of limitations such as not limited information about ice cover or tropical cyclones, etc. In conclusion, it can be assess that the SPOS system is satisfactorily used on ships as a browser forecast, but does not work well in planning the trip by navigators.
