    Cranes operators are exposed both to active and passive influences during work. Work positions of the operators, who were put through examinations, differed in a degree of complexity, therefore also in a degree of susceptibility to stress connected with the executed activities. Examinations were carried out for operators manning three kinds of cranes: teeming crane, repair crane and ingot mould stripper crane. The Holter technique and psychophysical tests according to the so-called Dortmund List were use

    Activities of the armed forces, particularly certain kinds of training courses, which require heavy combat and transport equipment as well as live ammunition, may have destructive impact on environment. It is unavoidable, but negative influence may and should be minimized. Necessity of relocating considerable forces and resources on long distances involves various means of transport. Current challenge of all the armies is the search for legal and organizational solutions so that appropriate education of soldiers and army’s efficiency are ensured with as few negative effects on environment as possible. Transport sector in contemporary economies is the most rapidly growing source of carbon dioxide and other greenhouse gases emission. It is estimated that transport in Europe is responsible for 28% of carbon dioxide emission, 84% of which is caused by road transport. Apart from obeying more and more rigorous norms and regulations concerning environmental protection issues, solutions should be searched for in systems used in transport telematics, minimizing fuel consumption and maximally making use of means of transport at the same time

    The presented research results specify the frequencies of an acoustic emission (AE) signal connected with phenomena occurring in the injection system of a diesel engine. From the time-frequency analysis the spectrum density was determined for a phenomenon or changes caused by the wear or damage of a selected injector component

    The issue of separation of oil emulsion using the ultrafiltration (UF) modules has been discussed in this paper. On the basis of preliminary studies performed in Maritime University of Szczecin, ultrafiltration modules have been suggested that comply a control test of Marpol Res. IMO MEPC 107/49. A new solution of the Neptun oil separation system with the use of patented ceramic UF modules has been presente

    This paper describes a concept of evolutionary neural networks application in decision process support during vessel manoeuvring in a restricted area. Selected algorithms, genetic operations, methods of coding and selection, and structures of evolutionary neural networks are considered in the paper

    The paper presents a problem of rudder deflection velocity normalisation considering steering gear power reduction as well as safety of ship. It has been assumed that the following safety conditions should be fulfilled: during manoeuvre dimensionless angular velocity of hull should obtain the value of 0.2 after distance equal to hull length after distance equal to 1.5 of length of hull, transversal displacement should be equal to 3B, where B denotes hull breadth. Examples of numerical computations for a Mariner type ship and conclusions are given

    The paper presents the experimental test performance of the jet thruster with outlet nozzle mounted in the ship bottom. The inclination between jet and bottom plate was 30 degrees and the jet was lateral to ship board. The decrease of thrust of the propeller due to the hull effect has been measured for three different hull breadths and for five bilge radiues

    This article discusses an algorithm of navigational data fusion. The algorithm has been verified through its implementation in a real time application. Parallel measurements of position obtained from two different GPS receivers have been integrated in this experiment. The experiment results are presente

    The radar is an example of a navigational device which enables monitoring of the sea areas. As every technical device, it is characterized by a certain limited level of functionality and reliability. Arranging observation stations so that plausibility of detecting any object at any place is greater than the threshold value is an operational research task. Formulation of the problem and the methods for solving it are presented in the paper

    The Odra River is presented as an essential element of the European north-south transport corridor. The Odra Waterway has been characterized in terms of navigation and navigational safety in its particular sections has been analyzed. The existing opportunities for its necessary and prompt improvement are pointed out

    The article presents the analysis of simulation research results of the newly designed ferry ‘Piast’ entering the modernized Ystad Port. The ship simulation model has also been described. After real time simulations the Monte Carlo method of underkeel water supply evaluation has been applied to assess the probability of ferry’s collision with the bottom. The results may be used in risk assessment of ships entering ports

    Abstract Efficiency and safety of maritime navigation depends very much on weather conditions. Since, in majority of cases, severe weather conditions are related with atmospheric fronts, it is crucial for meteorological support to provide a profound analysis and precise forecast of atmospheric fronts development and dissipation areas. The paper presents a method of determining the areas of frontogenetic and frontolytic zones worked out with the use of the results of research concerning the frontogenesis and frontolysis processes. The method is based on extensive analysis of the values of the frontogenetic function and the Q-vectors’ divergence

    The paper describes the present state of the regulations concerning ship stability and it has been concluded that stability criteria including design requirements are insufficient for assuring safety. The main cause of the majority of stability casualties (about 80%) are operational factors that are related to human factor. The author suggests applying a risk analysis adopting a holistic approach to stability safety as an alternative of the future stability requirements currently under development. This approach fits into the concept of goaloriented approach to safety that is now recommended by the Marine Safety Committee. The author discusses also how human errors could be dealt with in risk analysis and he provides an example of risk contribution tree based on a casualty recor
