  • Abramowicz-Gerigk, Teresa; Burciu, Zbigniew (Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Akademia Morska w Szczecinie, )
    The paper presents environmental factors influencing the safety of ship access to a port. The factors are classified into real time, short and long term ones from the point of view of modeling and real time risk assessment. An example of a long term prognosis for a surface current is given. The risk assessment of ship approach to a port based on a stochastic model of ship motions under wind and wave is proposed.
  • Abramowski, Tomasz; , (Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Akademia Morska w Szczecinie, )
    This study presents a wide range of possibilities resulting from the application of wing-in-ground boats as means of transport. Selected design and operation problems of this type of vessel are briefly discussed. The numerical example of calculations of viscous flow around the wing of a WIG craft gives a good view on the ground effect related with WIG craft motion.
  • Burzyński, Andrzej (Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Akademia Morska w Szczecinie, )
    In his article the author analyses the accuracy of objects which are situated on the sea. Research on selected objects has been carried out in the Vessel Traffic Service cov-ering the Gulf of Gdansk. The author compares positions of those objects on the basis of VTS and DGPS readings.
  • Drozd, Andrzej (Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Akademia Morska w Szczecinie, )
    In this paper an example of speed down curve construction for one ship type is pre-sented. The relationship between ship’s speed changes and environmental factors is defined on the basis of observational data. The artificial neural network was used for a regression analysis. Taking into account the fact that input data imprecision can hardly be avoided, which consequently makes the predicted ship speed approximate, the proposed notation of ship speed in given conditions has the form of fuzzy number.
  • Duda, Daniel; Szubrycht, Tomasz (Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Akademia Morska w Szczecinie, )
    The changes in political situation that have taken place over the last several years and an advancing globalization have put the problems of international shipping safety among the most important problems of the world today. New threats such as maritime terrorism, piracy and armed attacks have become a new challenge to marine transport. The article characterises certain operations below the war level, i.e. shipping control and protection. The authors define and specify the operations associated with the protec-tion and control of the shipping.
  • Dziedzicki, Krzysztof; Śmierzchalski, Roman; Łebkowski, Andrzej (Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Akademia Morska w Szczecinie, )
    Correct preparation of the crew for work can be obtained via long-lasting appren-ticeship at sea, or training at simulators. The simulator of the moving ship in the marine environment is presented. It has an ability to realize different training scenarios and the follow-up action of training in real-time. The simulator makes it possible to test the ship steering systems, to verify the collision avoiding systems, the testing of the autopilot etc.
  • Filipowicz, Włodzimierz (Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Akademia Morska w Szczecinie, )
    Passing a restricted area the ship’s master has to select one of the alternative routes or decide on a delayed passage. Among important imprecise and subjective val-ues are congestions encountered within the regions including route crossings or junc-tions. To foresee traffic within a confined area the decision maker has to cope with im-precision and to use fuzzy numbers. Fuzziness is expressed by intervals. Interval arith-metic embraces typical operations such as addition or multiplication, but also enables the selection of possibility level as well as the comparison of such values. Consequently, extended popular hierarchy builders can be used for the selection of the best option.
  • Gucma, Lucjan (Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Akademia Morska w Szczecinie, )
    This article presents selected probabilistic models used for the description of ship’s position in restricted areas. Two models based on a joint of normal and uniform distri-butions have been discussed in detail. These models can be applied for the estimation of accident probability and manoeuvring risk taken by ships sailing in restricted areas.
  • Gucma, Maciej (Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Akademia Morska w Szczecinie, )
    This article presents a method of pilot navigation systems research and the parame-ters of a PNS prototype developed after the second stage of optimization.
  • Hajduk, Jerzy (Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Akademia Morska w Szczecinie, )
    The vessel traffic in the Western Baltic Sea area is characterized by high concen-tration. This area is difficult for navigation. By a decision of the International Maritime Organization (IMO) new traffic separation schemes will be mandatory for ships from 01.07.2006. The question is if this new solution will be satisfactory for maritime admin-istration and navigators and if all problems willbe solved.
  • Juszkiewicz, Wiesław (Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Akademia Morska w Szczecinie, )
    The main goal of tracking systems is providing the observer with a proper safety assessment, including a possibility of proper and effective trial manoeuvre planning. For the trial manoeuvre accuracy examination, some typical scenarios were simulated in a radar simulator. The research results of trial function accuracy are presented in the article.
  • Kasyk, Lech (Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Akademia Morska w Szczecinie, )
    In this paper the leading function of a stream of fairway vessel reports has been de-termined. The discrete form of the leading function has been determined for three vari-ants: “multiweekly”, weekly and daily. For the latter the reports of ships passing the VTS reporting line “Police” on the Szczecin – Świnoujście fairway have been utilized
  • Kaup, Janusz (Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Akademia Morska w Szczecinie, )
    The paper presents guidelines for the determination of ship aerodynamic forces with the application of computational fluid dynamics methods. Numerical calculations were verified against the results from the wind tunnel. The techniques of grid making and furhter grid adoption for local flow characteristics were discussed. Special attention was paid to the problems of time limitations during grid generation and automation of thge computation process.
  • Kobyliński, Lech (Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Akademia Morska w Szczecinie, )
    New Load Lines regulations came into force on 01.01.2005. This is the result of the long time preparations within IMO SLF Sub-Committee. The work was aimed at the review of the provisions of the LL Convention and, in particular, revision of freeboard tables based on deck wetness concept. This aim was only partially achieved. The first part of the LL Convention including conditions of assignment was totally re-drafted, but freeboard tables were not changed. The subject of revising freeboard tables was eventu-ally deleted from the work programme of IMO.
