    Opis:
    The growing demand for transportation has brought even larger quantities of traffic in spatially limited port areas. Considering a diverse traffic mix, infrastructural overcapacity and busy schedule, port communities have started to face possible degradation of safety and environmental standards. To mitigate these problems, a number of different monitoring solutions of marine environment were deployed. Since conventional environmental and traffic data gathering by physical monitoring and sampling was logistically complicated and inefficient in time and resources, different approaches had to be considered. With the rise of accessible Internet of Things (IoT) technology some ports already installed smart monitoring devices such as smart buoys. The goal of this paper is to examine the concept and benefits of an automated smart buoy as a cost effective, easy to install device capable of real-time remote information sharing. Furthermore, the design and operational processes of existing automated smart buoy will be presented, along with solutions for tackling navigational safety and environmental problems.

    Opis:
    Taking advantage of coastal wave environment to carry out scaled ship model test is an effective testing technology for ship performance. In this paper, the method of spectral analysis is adopted to calculate the significant wave height, period, wave spectrum and some other parameters of some places along the North Sea area of China. The measured wave spectrum and the ocean spectrum are handled into non-dimensional form to evaluate their similarity. The influence of wind direction and tide on coastal waves was analyzed. And the results indicate that the coastal wave spectrum is similar to the ocean spectrum under some specific conditions.

    Opis:
    This paper describes a unique engineering method intended for the preliminary designing of marine echo-location systems. The solved designing problem consists in determining geometrical parameters and selecting structural materials for a vessel of a buoyancy necessary to contain measuring instruments of a given mass, as well as its maximum gabarites and operational submersion depth. The assumed variability range of the system’s parameters determines a space of permissible applicability parameters of the method. Stress level related to permissible and critical stresses was assumed to be safety criterion for the vessel. The method may be applied also to solving converse problems consisting in determining maximum permissible submersion depth for a vessel made of assumed structural materials and having given geometrical parameters. The presented description of the method is illustrated by an example of its application.

    Opis:
    In this paper, some issues of building a reliable, distributed measurement system for monitoring of water quality in reservoir Lake Dobczyckie are presented. The system is based on a measurement station that has the shape of a floating buoy which is supposed to be at anchor on the reservoir. Wireless data transmission problems that were encountered during the development of the buoy, modeling a radio link, and measurements of actual signal strength on the reservoir are discussed. A mathematical approach to procedures of early situation assessment was conducted, and specialized procedures were designed for measurement stations of the system. It is also discussed how such computations can improve a qualitative assessment of system performance in terms of real-time messaging.

    Opis:
    The high volume transported by ro-ro vessels has not come without a price. Accidents and incidents related to design – lack of bulkheads, instability, problems with cargo access doors, stowage, securing cargo and lifesaving appliances – are growing along with the size of the vessels themselves. One particular and recurrent problem is the degree of these giant box-like high riding vessels exposed to wind. Recently the effect of a tramontana – a fierce, sudden and short term regional wind – in the Port of Koper was to detach a moored ship, causing an accident. This paper will present a study of that accident, and through simulations and modelling determine an improvement that will allow berthing perpendicular to the stern ramp to function more securely.

    Opis:
    This study deals with a new concept of near-shore combined renewable energy system which integrates a monopile wind turbine and a floating buoy with heave-type wave energy converter( WEC). Wave energy is absorbed by power-take-off (PTO) systems. Four different shapes of buoy model are selected for this study. Power performance in regular waves is calculated by using boundary element method in ANSYS-AQWA software in both time and frequency domains. This software is based on three-dimensional radiation/diffraction theory and Morison’s equation using mixture of panels and Morison elements for determining hydrodynamic loads. For validation of the approach the numerical results of the main dynamic responses of WEC in regular wave are compared with the available experimental data. The effects of the heaving buoy geometry on the main dynamic responses such as added mass, damping coefficient, heave motion, PTO damping force and mean power of various model shapes of WEC in regular waves with different periods, are compared and discussed. Comparison of the results showed that using WECs with a curvature inward in the bottom would absorb more energy from sea waves.

There have been assumed, that positioning is realized on the basis of the position of the vessel and the essential issue is to determine the displacement of the reflection point of the acoustic wave as a result of refraction phenomenon.

    Opis:
    This paper is an introduction to the issue of buoys, i.e. signs normally produced with the non-dominant hand to ensure a spatial reference point for signs produced with the dominant hand. Simultaneous constructions of this type have been noticed in numerous sign languages, yet their equivalents have not been described in any detail for Polish Sign Language (PJM). The paper presents what can be said about the use of buoys in PJM on the basis of an analysis of a collection of empirical data extracted from the Corpus of Polish Sign Language (KPJM). The research confi rms that certain buoy types (fragment and depicting buoys) are frequent in PJM and can be found in recurring contexts, which speaks for considering them as a part of grammar of this language.

    Opis:
    Developing tourism and growing number of tourist and other smaller vessels and personal boats require a larger number of berths, outside dedicated ports, and harbours. Vessels can always anchor, but for ecological, and commercial reasons mooring areas with installed mooring buoys are better and more efficient solutions. However, choosing mooring areas, their size, number of buoys, etc. compared to choosing anchorage areas, is a much more complicated procedure, even more so for not having a unified form nor practice. This paper analyses some of the main issues in the selection of mooring sites and fields, focusing on the factors that should be considered in the planning process. As a result of the carried-out analysis some basic recommendations will be given concerning the choice of mooring field shape, swing radius calculation, distance from the shore, nearby vessels, and other obstacles.

    Opis:
    In this paper, to improve the mechanical behavior of DeepCwind semi-submersible floating offshore wind turbine (FOWT) platform mooring lines, the nonlinear catenary cables of the platform were divided into multi-segment and intermediate buoys. Mathematical formulations of the boundary element method (BEM) governing the dynamics of mooring line systems with buoy devices were described. This study was applied to the OC4-DeepCwind semi-submersible FOWT platform, which is designed for a 200-meter water depth with mooring lines consisting of three catenary steel chain cables at 120° angles to each other. The dynamic response of the multi-segment catenary mooring lines with different buoy radiuses and different positions along the cables was investigated. The full-scale platform was modeled in ANSYS-AQWA software, and the simulations were performed under harsh offshore conditions. The mooring line’s general arrangement, tension, strain and uplift force for different buoy radiuses and their position along the cable are presented and discussed. Moreover, platform motions in three directions (surge, heave, and pitch) were also analyzed. It was concluded that by correctly selecting the buoy volume and position along the cable, the tension of the cable may be reduced by up to 45%. By incorrectly selecting the buoy, the results caused adverse effects.
