Opis:
Modernisation of marine power plants in the transport vessel fleet to satisfy the requirements of the International Maritime Organization is an urgent scientific and technical problem. Currently, the use of catalytic selective filters, dry and wet scrubber systems and exhaust gas recirculation for marine diesel engines is widely used for this purpose. An analysis of the use of ejection gas-air coolers is presented as an additional method of emission reduction. However, the use of such device does not neutralise the harmful emissions of power plant engines, but only increases the volume concentration of their exhaust gases. But this will help to increase the efficiency of dispersion of harmful emissions, by reducing the concentration of harmful emissions to values not exceeding the maximum permissible concentrations. Its efficiency depends on the load mode of the diesel engine. It is found that the initial concentration of harmful substances in combustion products due to their dilution with fresh air at 100% engine load is reduced by about 50%. The values of the reduction of the concentration and temperature of exhaust gases with the reduction of the engine load to 75% and 50% depending on the louvre angle are obtained. It is proved that ejection gas-air coolers can be an effective additional means for compliance with modern environmental parameters, especially when vessels are in special areas of the world’s oceans.

Opis:
The article presents the results of a numerical simulation of the working process carried out in a diesel engine. In the applied utility program DIESEL-RK, the laboratory engine Farymann Diesel type D10 was implemented. A selected inoperability of its functional fuel supply system - reduced opening pressure of the injector pinj - was introduced. The values of adequate diagnostic parameters were determined: working gas temperature in the cylinder Tcyl, exhaust gas temperature Texh, combustion (flame) temperature Tcomb and concentration of nitrogen oxides in the exhaust gas NOx. Experimental tests were carried out on the experimental engine with the inoperative condition actually introduced, analogous to the numerical simulation, and the diagnostic parameters Texh and NOx were recorded. The results obtained by numerical simulation of the processes and during the active experiment on the experimental engine were compared.

Opis:
A good water quality is essential to sustaining the life of the organisms. The determination of water quality is needed as a direction to monitoring the water pollution. The purpose of this study is to examine the quality of the water and to determine the water pollution index based on the physicochemical parameters in Mimika waters, Indonesia. The sampling of water quality was carried out in October 2016 at six stations (Moga, Puriri, Inaoga, Keakwa, Atuka and Pomako waters). Then, the results were compared with the standard of sea water quality for biota marine based on the Decree of the Minister of Environment No. 51 year 2004. This study showed that the physicochemical parameters of the waters, such as water turbidity, BOD, NH3 and heavy metals (Hg, As, Cd, Pb, Cu, Zn, Ni and Cr), are still appropriate to the biota marine in all study stations. However, there is a parameter for which the quality standards were exceed in all locations, including water salinity for coral and seagrass, NO3, PO4 and H2S. The result of pollution index calculation at coastal waters Mimika are classified as lightly polluted (Keakwa and Pomako waters), and moderately polluted (Moga, Puriri, Inaoga and Atuka waters) with the pollution index values of 3.51 to 6.95. It is important to notice that the parameters of quality standards which had been exceed such as NO3, PO4 and H2S are the environmental parameter for nutrient elements and can trigger eutrophication in the waters.

Opis:
A seaport is presented in this article as a system composed of various types of waterways. The author has defined relationships between port waterway system elements and conditions of safe operation of ships in port. Relationships were determined between the conditions of safe operation of ships and the parameters of the following port waterways: anchorage, fairways (approach and inner channels, port entrances), turning area and port basin. The identified relationships between port waterway system and conditions of safe ship operation provided a basis for formulating the objective function of waterway parameter optimization during port design. In practice, these relations were used to determine the parameters of the Outer Container Terminal being built in Świnoujście, where two optimization problems were to be solved: 1. The optimization of approach channel parameters, 2. The optimization of parameters of the port entrance, turning area and port basin. The Outer Container Terminal in Świnoujście is expected to handle ocean-going ships with a length overall Lo = 400 m, and its projected capacity is estimated at 1.5 million TEU per year, a figure that can be doubled in the future.

Opis:
Marine engines are very complex technical objects, having many important functional systems, which include, inter alia, injection system, characterized by high unreliability. In this system, there may be different types of defects (damage) that affect the engine parameters, including specific fuel consumption, as well as failures endanger the safety of the ship. The indicator diagrams and analysis of indicated parameters have limited utility in the diagnosis of damages of marine engine, although this is a method commonly used in operational practice. To achieve greater diagnostic effectiveness, when, based on indicator diagrams, are calculated and then the characteristics of heat release is analysed - net of heat release characteristics and the intensity of the heat release, it was demonstrated. This procedure is particularly effective in the diagnosis of damages of marine diesel engine injection system components. It has been shown that the characteristics of heat release contain information about the condition of the injection systems, which enable to diagnose their failures. This is shown on the example of a clogged nozzle holes (their carbonizations). The obtained results allowed selecting the diagnosis symptoms, useful in detecting these faults in the injection system, from the characteristics of heat release: net heat release (Q) and intensity of heat release (q). The object of the research was typical marine medium speed engine Sulzer A25/30.

Opis:
The Chandipore beach, situated in Balasore district, Odisha, 21°28΄N 87°01΄E / 21.47°N and 87.02°E shows an interesting nature of wave action as the water recedes up to an average of 5 kilometres during the ebb and tide, resulting in a vast, dynamic array of coastal biodiversity. It gets exposed to a huge tourism load every year and is faced with multidimensional anthropogenic interactions manifested through a varying gradient of urbanizing parameters like cattle grazing, automobile exhaust, constructions in vicinity of beach area, sewage and solid disposals etc. Present piece of work aims at documenting the premonsoon abundance and diversity of marine invertebrate fauna in this eastern Indian sea beach. Adamsia palliata, Carcinoscorpius rotundicauda, Diogenes rectimanus, Sabella sp., Astropecten mauritianas were found to be few of the prominent faunal representatives. Significant differences in respect of species richness have been observed among different selected ecozones through the coastal landscape based on tidal activity and anthropogenic exposure (F5.73, p ≤ 0.05). Such type of field-based observations leads to the scope of further estimation of the ecological status of these native organisms, their intra and inter-specific associations and functional contributions to coastal landscape playing role as a potential bioindicator, which may in turn become instrumental in frame working the future conservation scheme of these natural assets.

The process of the atomization and formation of the fuel spray can be described by macro- and microstructure parameters. Knowledge of these parameters may be a key information to conduct further optimization of the combustion process. This paper presents the research results of the microstructure parameters of the diesel oil spray atomized with marine engine injector. A measurement technique, named Laser Induced Fluorescence (LIF) in the combination with Mie scattering was used to determine LIF/Mie ratio across the spray. The fuel was injected into a constant volume vessel. LIF and Mie signals were recorded by two cameras at the same time. Nd:YAG pulsed laser was used to create light sheet for spray illumination. Wavelength of λ = 266 nm was used in this study.

Opis:
W referacie przedstawiono wyniki badań wpływu wybranych uszkodzeń okrętowych silników tłokowych na parametry pracy silnika oraz skład spalin. Silników okrętowych nie można zaliczyć do obiektów technicznych o zadawalającej niezawodności. Omówiono w referacie dane statystyczne dotyczące ich awaryjności. Na tej podstawie wytypowano do badań typowe uszkodzenia występujące w dwóch ważnych układach funkcjonalnych: wtryskowym i doładowania. Badania przeprowadzono w warunkach laboratoryjnych, w formie eksperymentu czynnego – poszczególne uszkodzenia symulując. Obiektem badań był silnik okrętowy, czterosuwowy, średnioobrotowy firmy Sulzer. W referacie omówiono wyniki badań, zwracając uwagę nie tylko na wpływ poszczególnych uszkodzeń na zmianę wartości najważniejszych parametrów badanego silnika, ale także na zmianę składu spalin. W tym przypadku szczególnie istotna była ocena wpływu danego uszkodzenia na poziom emisji związków toksycznych.
The paper presents the results of research on the impact of selected marine diesel engine damage to the operating parameters of the engine and the exhaust gas. Marine engines can hardly be called technical objects of satisfactory reliability. Statistical information’s on their failure were discussed in this paper. On this basis typical damages primarily occurring in two major functional systems: injection and turbocharger, were selected to the research. The research was conducted in laboratory conditions, in the form of active experiment – simulating the particular damage. The object of the study was the ship’s engine, for stroke, medium speed, Sulzer. The paper presents results of the research, paying attention not only to the impact of individual damages to change the most important parameters of the test engine, but also to change the composition of the exhaust gases. In this case particularly it was important to assess the effect of the damage on the level of toxic compounds emission.

During research works concerning piston internal-combustion engines specifications of these objects are often needed. This data is usually dispersed and reaching to some is hampered or impossible. Therefore, an electronic database was drawn up about the most important ship producer’s piston internal-combustion engines for needs of exploitation investigations in the destination of gathering the necessary information. This paper presents a database of global marine diesel engines. For example, engines of the following companies were described: Akasaka Diesel, CAT, Cummins, Fiat, Hyundai, MTU, Niigata Power Systems, Pielstick, Scania, Volvo Penta etc. Information was obtained from various sources, so as websites of producers, advertising catalogues, or books and magazines about subject matter associated with marine diesel engines. This information was collected and written with the help of the program Microsoft Office. Gathered data was divided in engines of the main drive and emergency, containing details about producers, types and parameters of 2-stroke engines and four-stroke. The base enables supplementing and the alteration of entered data. Produced engines are usually operated by several dozen years after producing on swimming objects. Produced internal combustion engines are usually operated by several dozen years after producing on floating objects, and producers are merging or are stopping existing.

The paper presents a method of identification parameters of shaft line alignment and its influence on operational reliability of marine propulsion system. The discussion about shaft line parameters (bearings' reactions, bending moment and shear forces acting on crankshaft or gear box, and stresses distribution in the shaft line) which has an influence on marine propulsion system reliability was presented. Proper shaft line alignment is often a problem for repair shipyards, for aged ships without sufficient documentation. Some data can be draw by measurements; e.g. shaft line dimensions or intermediate bearings' reactions. Other data (stern tube bearing load, real axis of shaft line) have to be determined on the base of calculations. Author proposed combined experimental-analytical method for identified and optimization (correction) some existing parameters and checking power transmission system’s foundation. Specialised software (based on Finite Element Method) has been developed for shaft line alignment calculations. Main novelties of the software are elastic supports (model of bearings – boundary conditions) of the shaft line, continuous support as a model of stern tube bearing and influence coefficients calculations. An example analysis with discussion has been performed for cargo ships with medium-speed main engine. Multi-variant computations supported by measurements of the ships’ shaft line have been carried out. Changes in shaft line alignment have been proposed in order to increase reliability of propulsion system.

The article discusses the problem of determining the characteristics of heat release based on experimental indicator diagram for diagnostic purposes. The importance of the operational diagnosis of marine engines is the analysis of indicator diagrams was identified. In addition to analysing changes in the values of indicated, should be aimed to oriented broader analysis, including the determination on the basis of experimental indicator diagram of heat release characteristics during the combustion process. Then it is essential to choose the right model of heat release for reciprocating piston engines with direct fuel injection. In the diagnostics of piston engines, including marine engines, special interest arouses use single-zone model based on indicator diagrams as a source of information. Based on the results their own research we analysed the impact on the characteristics of heat release of simplifying assumptions in the model of heat release, including constant value adiabatic exponent. In the temperature, range 300÷2800 K waveformsκ are considered to be linearly dependent on the temperature. Based on the above, for the gas temperature from 800 K to 1850 K value of the exponent κ decreases about 3%. The effect of the value κ on the course of characteristics q and Q, to the typical marine engines was shown.
