    The article presents a combined system of a large power ship power plant. The system consists of a piston internal combustion engine and the steam turbine system which utilises the energy transported with the exhaust gas leaving the internal combustion engine. The analysed variant of the combined cycle includes a Diesel engine and a steam turbine with a single-pressure waste-heat boiler. The numerical calculations were performed for two low-speed internal combustion engines made by Wärtsilä and MAN Diesel \& Turbo, each of an approximate power output of 54 MW. The assumptions and limits which were used in the calculations done using a specially worked out code are included. The energy optimisation of the entire combined ship power plant was done taking into account only the thermodynamic point of view, leaving aside the technical and economic aspects

    Modeling of ship motions in waves concentrates in most applications on the response amplitude operator (RAO). This mathematically not demanding method of analysis is very attractive, but loses some essential information in certain situations. The objective of present contribution is to establish and investigate preliminary foundations for a seakeeping model as optimal for under keel clearance (UKC) estimation. A special attention was devoted to transients of motions, stationary harmonic motions, coupling between degrees of freedom, and the wave force transfer functions – all in the aspect of shallow water environment

    PISCES II is a simulator designed to conduct research and training related to the rescue operation in the event of an oil spill on any of the world region. The program includes a built-in mathematical model, enables the oil spill of crude oil to observe the interaction in user-specified external conditions. This paper presents the results of the analysis of mathematical model simulation Pisces II, the behavior of the oil slick in selected hydrometeorological conditions

    Maritime surveillance from space is useful for many applications, such as fisheries control, maritime border control and maritime security. A new generation of satellite-borne Synthetic Aperture Radars is able to provide resolutions of down to 1 meter. In the case of maritime targets, however, their motions lead to blurring in the SAR images, so these high resolutions cannot be attained. Scientific research into how to surmount the existing limits on the use of high-resolution images for maritime surveillance would be of great utility. In this context, high resolution SAR data were collected from ships that have been fitted with motion sensors in order to understand vessel motion impact on detection and recognition capability

    This article deals with issues relating to the evacuation of people from large passenger ships. Factors affecting the safety of passenger ships at both design and operational stage are described. The vital regulatory documents concerned with evacuation from ships are indicated. A concept of seeking an optimized evacuation plan at the design stage is presented. It aims at shortening the time of possible evacuation and at current on board planning of evacuation, taking into account inaccessibility of some escape routes

    Using laser rangefinders or other distance measuring tools offers an opportunity to create new ship waterplane position finding algorithms in restricted areas. The achieved by such system redundancy of positioning system will affect on ship’s safety and influence navigation which is dominated by one system (GPS and its derivatives). This paper is focused on developed optimization gradient algorithm and its improvement, algorithm with random start position

    In the paper the priority of technical means and methods of navigation at contemporary seagoing ship was discussed. The role of magnetically compass and gyrocompass at the condition of contemporary ship was described. Effectiveness of gyrocompass and magnetically compass from point of navigation and economy was analyzed. The result of analysis is reflected at the recommendation for navigators and managers of ship’s company

    The described in literature components validity measures (the order of the smallest cross section measurement of streams, number of occurrences of events in the Fault Tree, Birnbaum, Veseley-Fussell’s measures, the potential of reliability improvement, Lambert’s measure ...) relating mainly to the concepts of reliability and reliability structures is characterized. Concepts of studying functional structures of complex technical systems are presented. Directions and the amount of streams of energy factors flow in the systems will be analyzed. The analysis will be performed for the so-called dynamic functional structures. The validity and importance of the component in the system is assessed on the basis of the number of streams of energy factors which flow to and from the component. The greater the number of those streams, the more responsible for the operation of the system in this state is the component

    This paper presents a study of ships passing distances in coastal waters based on data from the AIS. Examinations are designed also to work towards the development of probabilistic domain that is an area in which the navigator is trying to keep free from other vessels. This article has been hypothesized for the distribution of ships passing distances from which you can build a probabilistic domain. The article summarizes the studies for three types of ships: tankers, passenger ships and cargo vessels and is comparing the shapes of domains for each of them in three situations: overtaking, crossing, vessels on the opposite courses. Studies were carried out in the Gulf of Pomerania

    Evaluation of accuracy of position coordinates’ determination in respect to floating marks, with free adjustment method applied, has been a target of the paper. General theory of geodesic adjustment – classical one based on least squares method and free adjustment – is presented in its first part. Main part contains description of the research. It was conducted based on geometric navigational structure which elements had been formed by beacons placed in the Bay of Gdańsk. It consisted in simulating results of measurements made in respect to marks of this structure (bearings and distances) and calculating the position coordinates based on them, as well as its accuracy. The calculations were made with the method of classical geodesic adjustment and free adjustment applied. Discussion about obtained results of the research and general conclusions are given in the ending part of the article
