Opis:: The article presents the methodology of calculation of principal parameters of ship’s hull dimensions, called „significant ships list”, at preliminary stage of design process. Knowledge collected in the database is related to new buildings classified according to type, displacement, or DWT, shipping class, maximum speed etc. Are analysed dimensional constraints due of Froude Number, ships dimensional coefficients block and weigh coefficient, relations of main dimensions such as L/B, B/T, L/H, B/H etc. [7]. Those parameters coming out from ship-owners requirements like type of ship, load capacity, type of cargo, shipping zone, speed and some more. Very helpful tool for such analysis is list of significant ships created for specified types of ships. Mentioned lists are very effective under conditions that cover broad-spectrum new buildings and data included are credible. Uncritical taking values included in significant ships list can lead to critical errors in selection of main dimensions of a ship or its propulsion powering. For that reasons, basing on analysis, as main criteria of similarity of ship’s hull were assumed mass coefficient, block coefficient and Froude Number [2]. That procedure has significant impact at proper estimation of propulsion power. Another reliable parameter of evaluation of power seems to be relation between power and load capacity Ne/D.

ship’ dimensions
Opis:: TEU number, which is the container ships’ crucial designing factor, directly influences the main hull dimensions such as displacement V , length L, breadth B, draught T, their combinations and block coefficient CB. The main dimensions have a great impact on developing the ships resistant performance. Thus, it is really fundamental to establish the correct dimensions of the hull during the design and ship building process. Estimating the shape of the ship’s hull, that comprises its main dimensions, is one of the basic tasks as part of the preliminary design stage. The most significant decisions determining ships performance, its duration and building costs are made at the beginning of the preliminary stage, when the costs are relatively low. It is important to limit the total ship resistance, for instance, by lowering the wave ship resistance as much as possible, especially when the operational speed and TEU number carried by one vessel is increasing. That resistance depends on the operational speed expressed by Froude number. The resistance criteria and the existing hull dimensions limits, resulting from ships route, must be taken into consideration bearing in mind safety conditions such as ships stability and seaworthiness, when the main ships dimensions are being determined. In the paper are presented general rules for calculations of ship’s hull principle dimensions and total power of engines of container ship 1300TEU and 18 kn at preliminary stage of design process.

Opis:: The power of main engine must be determined in such a way to let the seagoing ship reaches the predicted, in the agreement with the ship owner, service speed. Significant influence on the main engine power, apart from the ship 's speed, has a geometry shape and the dimensions of the ship's hull. Begins from the general form of Admiralition's equation, it is essential to establish the specific quantity parameter for the estimation of main engine power. That parameter can be described by the displacement, DWT, LBT, TEU number, the 14 tons TEU number etc. depends on the type of the seagoing vessel. The estimation of the specified maximum continuous rating SMCR based on the quantity parameter can be practicable in the preliminary design stage because of the small number of the known design data and the importance of the design decisions made at that level. The characteristic quantity parameter to establish the main engine power of the seagoing ship has been determined using the data of the contemporary container ships in operation. The research has been done in the whole range of the container capacity in TEU, where the combustion, reciprocation engines are used to propel the seagoing vessels. The statistical and regression tools have been utilized in the data analysis process to determine the quantity parameter.

Opis:: Preliminary ship owners' assumptions for new ship consist of deadweight (for container vessel load capacity TEU), speed shipping line and others. Taking it as a base, in early stage of design one has to select propulsion type. This goal needs definition of principal dimensions of a vessel, which are the base for further calculations of hull’s resistance and evaluation of necessary power of main engine (engines) to fulfil shipping requirements. Selection of main dimensions of vessel is limited by rules regarding buoyancy, stability, hull strength, manoeuvring capability, and limitations related to seaways or harbours characteristic. In this paper is presented the methodology of calculation of principal parameters of a vessel, necessary for calculation of displacement in relation to vessel’s type, volumetric coefficients, Froude number, and others values affecting ship’s dimensions. It is about midship section coefficient, waterline coefficient, prismatic coefficients and hull feature and area coefficients. Those values are necessary for calculation of hull resistance. In the table are presented comparison of results of calculations above mentioned values and movement resistance and propulsion power of three container vessels representing different load capacity and one bulk carrier. There are also presented different calculation methods of transverse midship section coefficient and wet area coefficient, for 5000TEU container vessel.

Opis:: In this paper, the problems of diagnostics of main propulsion marine engines are presented. Diesel or turbine engines are used for main propulsion of vessel power plants. Marine engine is a complex technical object. For the purpose of diagnostics it is convenient to divide the engine into several units - subsystems such as: piston -crank assembly; working medium exchange system, fuel supply system, lubricating system, cooling system, starting up -reversing system; combustion chamber. The organization of the marine engine diagnostic process can usually come down to two stages, general diagnostics and damage location. Most popular in marine engine diagnostics have been the periodic run analyzers, called pressure analyzers, electronic indicators or MIP (Mean Indicated Pressure) calculators. Marine turbine engine operation requires professional technical supervision. The basic diagnostic system of marine turbine engine is able to assess the current engine condition and give forecast concerning its future operation in a complex way with the use of computer technology. Working out operating decision was based on proper preparation of operational parameters which were processed in a computer according to defined algorithms. Diesel engine diagnostic systems of merchant vessel engines are discussed. Finally, description of diagnostic methods implemented in turbine and piston engines in Polish Navy ships are introduced.

Opis:: The paper presents general rules of utilization of database, called „significant ships list,” for preliminary design of ship’s propulsion and configuration of power plant. Knowledge collected in the database is related to new buildings classified according to type, displacement, shipping class etc. It encompass general dimensions, characteristics of mobility ,propulsion’s power and type of main engines and propulsors, electric power plant, boilers and main mechanisms of a power plant. In the paper is presented method of utilization of the significant ships list during design of a container ship with capacity of 1300 TEU and speed of 18 knots. The first step of propulsion and main engine’s selection is determination of main dimensions, i.e. displacement, length, draft and breadth. That dimensions cannot be selected random way, due to hull’s mobility, stability and durability constraints. The list of significant ships consisted of 30 units, and amongst them, 17 were selected and analyzed. Others were rejected because of significant difference from mean values what could be due to different class of the ships.

Opis:: Permanent growth of the container shipbuilding has led to the need of research - developing activities with references to design and ship building process. The requirements for the container vessels have been modified and changed compared with the ships built in the eighties of the past century. The ships capacity have been increased up to and even above 10 000 twenty feet containers (TEU) with the service speed above 25 knots. For such a giant sea going vessels with the overall length above 300 meters and draught above 10 meters the ship hull resistance characteristics have been modified. Those conditions bring to the situation where the propulsion power for the seagoing ships reached 80 MW. The estimation of the main engine power relation in the preliminary design stage is the main aim of the paper. The problem is such important as in that stage the most important design decisions with relatively low investment costs are determined. Moreover, the preliminary design stage distinguishes that the designer possesses just a few design parameters given by the ship owner of the future vessel. That is why the correct choice of the main engine power is difficult to determine. Determination of the main propulsion power impacts the electric and heat energy amount and the production way of both energy forms. The main engine equation has been determined based on the container ship's parameters for the entire range of container vessels load capacity (TEU). The values of the design parameters have came from author 's data base for the contemporary container vessels.

Opis:: The paper presents comparative analysis of energetic possibilities of different ships with close parameters of displacement and operational ailing range, for selected type of main engine. Analysis is related to three types of ships, i.e. bulk carrier, tanker and container ship, with assumed displacement at level of 120 000DWT and typical for that ships sailing speed. The analysis concerns shipping route from Gdynia to Shanghai. First step of conducted analysis was based on elaboration of the list of contemporary similar ships for every class, their general dimensions, dimensional coefficients, and subsequently evaluation of hulls resistances using Holtrop – Mennen Method necessary for calculation of propulsive power, main engines’ selection, most convenient for every type of ship and calculation of trips durations and fuel consumptions. All calculations were done assuming typical cruising speed for considered types of ships, it means 25 knots for container ships and 15 knots for tankers and bulkers. Results of carried out calculations lets come to the conclusion that total time of trip duration of container ship is 1.5 times shorter and fuel consumption is 2.5 times higher comparing with tankers and bulk carriers going on the same trip. Taking under consideration constantly growing prices of heavy oil, that situation is inconvenient from economical point of view. Above facts explains general trend to reduce speed of container ships presented by almost all shipping companies. The way of speed’s reduction is decreasing of continuous power rate of main engine, what is related to necessity of blinding or dismounting some numbers of turbochargers. Hypothetic example of such operation and its impact at operational properties were analysed, and results showed, that exploitation parameters of the container ship begun closer to bulk carriers and tankers but could not achieve proper level of efficacy due to not optimal hull shape and engine characteristic.

Opis:: Development of on-line diagnostic (monitoring) method of marine propulsion system working parameters is the authors' target. Crankshaft springing characteristics are one of the most important from the ships' main engines reliability point of view. Planned monitoring system will be able to verify crankshaft springing characteristics by continuous measurements of the crankshaft free-end's axial deformations. Development of the analysis methods of crankshaft's stiffness characteristics is the first step of planned SHM system. The main purpose of research is method developing of the springing analysis for the marine crankshafts in the high-power engines. Crankshaft modeling method, by Finite Element Method, has been discussed. Short overview of the crankshaft boundary conditions is presented. Bearings' oil film stiffness characteristics, ship hull stiffness characteristics and temperature deformation of the ship hull and main engine body are taking into account. Influence of the crankshaft's foundation stiffness on springing values is analysed. During the analyses it was proved that flexibility of engine foundation has a big influence upon the value of crankshaft springing. The authors' method of cylindrical mass and gas forces decompositions has been presented. Analysis of modeling precision of piston-crank system's forces has been performed. Results of calculations are well compatible in the terms of quality with the measurements data.

Opis:: Stały wzrost zapotrzebowania na handel morski spowodował silny rozwój floty kontenerowców. Wielkość światowej floty kontenerowców wynosiła 3400jednostek w marcu 2005 a zaledwie rok później osiągnęła ona wartość około 3800 jednostek. Co więcej, światowa lista zamówień na kontenerowce zawiera ponad 1000 jednostek. Liczba największych kontenerowców rośnie zgodnie z liczbą pływających po morzu kontenerowców. Przewidywalny jest wzrost zapotrzebowania na małe statki dostawcze i statki dostawcze z większą pojemnością handlową, oznaczającą większą liczbę TEU na pokładzie i większą prędkością rejsową, wzrost wynikający z większej liczby kontenerowców o dużych pojemnościach zawijających do kilku głównych portów morskich. Te małe statki dostawcze i statki dostawcze zapewnią handel pomiędzy dużymi terminalami kontenerowymi i małymi portami spełniając funkcje zaopatrzeniowe. Współczesne statki kontenerowe mają pojemność ładunku dochodzącą do 14 000 TEU i przewiduje się, że pojemność ta osiągnie wartość 18 000 TEU z prędkością podróżną wynoszącą 28 węzłów. Powoduje to konieczność wykorzystania jako głównych silników statków silników Diesla o mocach wyjściowych dochodzących do 100 000 kW ze sprawnością około 50%. Artykuł zawiera klasyfikację floty kontenerowców opartą na liczbie TEU i obszarze żeglugowym, jak również zawiera opisy konfiguracji morskich siłowni dla współczesnych kontenerowców, z uwzględnieniem napędu głównego, siłowni elektrycznych i parowych. Ponadto, omówione zostały współczesne trendy w budowie kadłubów okrętowych i morskich siłowni.
Permanent growth of sea trade demand has contributed to strong expansion of container carriers. The capacity of the worlds container fleet was about 3400 vessels in March 2005 and only one year later it reached the number of about 3800 ships. What is more, there are over 1000 container carriers in the world's order book. The number of the biggest capacity container carriers is growing along with the number of container vessels at sea. The increasing demand for small feeders and feeders with higher trade capacity, meaning more TEU on board and higher en route speed resulting from higher number of large capacity container carriers that will call at a few main seaports, is predictable. These small feeders and feeders will trade between big container terminals and smaller ports as suppliers. Contemporary container vessels have a load carrying capacity of up to 14 000 TEU and it is foreseen that the capacity will reach 18 000 TEU with voyage speed amounting to 28 knots. It causes the necessity of using diesel engines whose output power is even 100000 kW with an efficiency of about 50% as the main ship propulsion. The container vessel fleet classification based on TEU number and trading area as well as configurations of marine power plants for the contemporary container vessels regarding main propulsion, electric power and boiler plants have been shown in the article. Moreover, the trends of ship hulls and marine power plants are discussed.

Opis:: The paper presents some problems of carrying out measurements of energetic characteristics and vessel’s performance in the conditions of sea examinations. As the object of propulsion characteristic determination was selected the ship with fixed pitch propeller. In order to formulate models of power characteristics, in first, known physical aspect were taken and subsequently statistic theory was implemented. Models of propulsion performance were built basing on two theoretical methods of determination of required shaft power and torque at a hub, as the function of propeller’s revolutionary speed and sailing condition represented by dimensionless coefficients. Model number one, based on Silukov method presents function with variable power index, of shaft power in domain of revolutionary speed. The second one presents model of torque variations, based on Silovic – Fancev method. For verification of models were taken presented in available bibliography, results of researches of ship’s propulsion systems [6]. We also discuss the manner of reducing the results of measurements to the standard conditions. We present the way of preparing propulsion characteristics and the analysis of examination uncertainty for the measurement of torque. Statistical analysis of deviation of results, using three models, proposed in the paper. As a result of analysis, one point from primary data set was rejected due to its unreliability, what was resulting with higher adequacy of characteristics.

Opis:: Permanent growth of sea trade demand has contributed to strong expansion of container carriers [5, 6]. The number of the biggest capacity container carriers is growing along with the number of container vessels at sea. The increasing demand for small feeders and feeders with higher trade capacity, meaning more TEU on board and higher en route speed resulting from higher number of large capacity container carriers that will call at a few main seaports, is predictable. Such a developing way of contemporary container vessels have led to the need of research-developing activities with references to design and ship building proces s, and new view at the electric matters. Approximations in use to determine the container vessels electric power are not accurate any more for the contemporary container carriers. Revision of the electric power relations and searching for the new mathematical models let determine with an essential approximation the electric power demand for contemporary vessels. The electric power calculations for the contemporary container carriers where the diesel and shaft generators have been used within whole range of container capacities, have been shown in the article. The electric power using multiple regression model has been calculated based on values collected in the container vessels data base. Different electric power relations have been determined for the container vessels with diesel and shaft generators and different for the ships with diesel generators only. Moreover, the diesel generators number and power have been discussed.
Znaczący rozwój transportu morskiego doprowadził do silnego rozwoju statków przewożących kontenery [5, 6]. Wraz z progresywnie rosnącą liczbą nowych statków kontenerowych rośnie ich pojemność kontenerowa. Dla rozwoju dużych jednostek kontenerowych przewiduje się wzrost zapotrzebowania na tzw. szybkie dowozowe jednostki kontenerowe o większych niż dotychczas możliwościach przewozowych tj. większej liczbie kontenerów i większych prędkościach eksploatacyjnych. Taki kierunek rozwoju współczesnych kontenerowców doprowadził do potrzeby prowadzenia działań badawczo-rozwojowych w zakresie projektowania i budowy statków kontenerowych oraz konieczność innego spojrzenia na sprawy energetyczne tych jednostek. Stosowane do niedawna przybliżone zależności na określenie mocy elektrycznej kontenerowców coraz bardziej odbiegają od rzeczywistej mocy j instalowanej na współczesnych statkach kontenerowych. Weryfikacja zależności na dobór mocy elektrycznej oraz poszukiwanie nowych modeli matematycznych, pozwoli już we wstępnym etapie projektowania określić z dużym przybliżeniem zapotrzebowanie na moc elektryczną tych statków. W referacie przedstawiono ocenę mocy elektrycznej współczesnych statków kontenerowych dla całego zakresu stosowanych pojemności kontenerowych, w których do wytworzenia energii elektrycznej wykorzystuje się spalinowe zespoły prądotwórcze oraz prądnicę wałową. Moc ta została wyznaczona w oparciu o model regresji wielokrotnej na podstawie analizy parametrów zgromadzonych w formie bazy informacji o kontenerowcach. Przy wyznaczaniu zależności na moc elektryczną dokonano podziału na statki, w których do wytworzenia energii elektrycznej wykorzystywane były prądnice wałowe i spalinowe zespoły prądotwórcze oraz jednostki, w których moc elektryczna wytwarzana była tylko przez spalinowe zespoły prądotwórcze. Jako uzupełnienie rozpatrywanego zagadnienia przedstawiono kwestie, na które należy zwrócić uwagę dobierając liczbę i moc spalinowych zespołów prądotwórczych.

Opis:: In this paper are presented the methodology of calculation of hull resistance components, principal parameters of a vessel, necessary for calculation of displacement in relation to vessel’s type. That methodology concerns analysis of designing ways at early stage of ship’s power calculation. Ship owners' preliminary assumptions for new ship consist of deadweight (for container vessel load capacity TEU), speed shipping line and others. Taking it as a base, in early stage of design one has to select propulsion type. This goal needs definition of principal dimensions of a vessel, which are the base for further calculations of hull’s resistance and evaluation of necessary power of main engine (engines) to fulfil shipping requirements. In the paper, are presented major constraints for designing of new vessels coming from ship-owner assumptions such as seafaring limitations and safety of shipping regulations due to Classification Societies Rules or coming out from designing experience. In the paper are presented components of ship’s resistance and methods of total resistance calculations what is a basis for power calculation and propulsion designing. Moreover, are presented results of calculations of resistance components of different types of ships, and variety of displacement and sailing velocity. It has to be assumed, that presented method concerns preliminary design stage and can vary from different ships classes and constructions of hulls.
