Opis:: This paper describes development trends of modern cruise liners and their main propulsion plants as well The growing size of such vessels and growing power of propulsion plants is observed in the population. Diesel-electric propulsion plants, combined propulsions plants CO D AG type (diesel and gas turbines) and COGES type (gas turbines and steam turbines) are mostly used on this class ships. In this types of propulsion diesel engines, gas turbines and steam turbines drive generators thus creating central electric power station to supply electric power to main propulsion electric motors and to ship electric network as well. Medium speed diesel gear type main propulsions are used on older cruise liners only. The paper presents the method of preliminary estimation of ship energetic system parameters i. e. main propulsion power, onboard electric power station power and auxiliary boilers capacity. The method is based on statistic analysis of cruise liners being in service and under construction. Statistic methods are elaborated in Department of Marine Propulsion Plants of Gdynia Maritime University. These methods make possible in simple and quick way to estimate parameters of ship energetic system. The estimation is carried out with good correlation coefficient and high coefficient ofregression determination. Statistic methods make also possible to forecast energetic systems parameters for ships to be built in the future.

Opis:: The paper presents the method of preliminary estimation of harbour tugs main propulsion power and on board electric power station based on statistical analysis. At the beginning of paper, the classification of tug boats is executed. Tug boats are classified according to their type of service, type of main propulsion, equipment and way of service. For harbour and roadstead tug boats, the analysis of main propulsion plants and on board power station is executed. Pushing and tractor propulsion plants are presented in which different types of thrusters i.e. azimuth, cycloid and classic propellers are analysed. Advantages and defects of each type of main propulsion are pointed. Statistic methods of analysis are elaborated in Department of Marine Propulsion Plants of Gdynia Maritime University. These methods make possible in simple and quick way to estimate parameters of ship energetic system. The estimation is carried out with good correlation coefficient and high determination of regression coefficient. Statistic methods make also possible to forecast energetic systems parameters for ships to be built in the future. Dependencies for main propulsion power and electric power of onboard power station are not universal for all types of ships. They should be elaborated separately for each type of ships. In this paper, the results concerning only harbour and roadstead tug boats are presented.

The analysis contains the biggest ships of this class Q-Max and Q-Flex. A new type of LNG carries named LNG RV (Liquefied Natural Gas - regasification vessel), which perform regasification of cargo in discharge place. This kind of vessel discharge can last in several days. LNG in gas form is directly pumped into receiverpiping system. Liqueified Natural Gas the natural prepared earth gas to the transport and the further distribution through the removal of undesirable impurities and the condensation. The dynamic development gas ships and tendencies to enlarging their carrying capacities will lead in the short time to the rising of ships having the loading-volume of 300000. m3 and even exceeding this value. In Particular, the LNG carrier with the spherical (Moss) type tanks, the inside of a spherical tank of LNG carrier, the LNG carrier prismatic type tank during a assembly, membrane type LNG carrier, distribution in containment systems on LNG fleet distribution of existing LNG carriers in service and on order (number of ships), distribution of propulsion systems of LNG fleet on order.
W pracy przedstawiono tendencje rozwojowe grupy statków do przewozu gazu naturalnego w formie skroplonej, nazywanych gazowcami LNG (ang. Liquefied Natural Gas). Zwrócono uwagę na wciąż powiększającą się zdolność przewozową tych statków, przekraczającą obecnie objętość 200 tyś. m . Analiza obejmuje największe statki tej klasy Q-Max oraz Q-Flex. Przedstawiono tez zupełnie nowy profil zamówień na rynku morskiego transportu gazu naturalnego, który stanowią statki LNG RV (ang. Liquefied Natural Gas - Regasification Vessel), które dokonują odparowania (regazyfikacji) LNG w miejscu jego wyładunku i przez kilkanaście dni wtłaczają gaz do podmorskiego rurociągu. Dynamiczny rozwój gazowców oraz tendencje do zwiększania ich zdolności przewozowych doprowadzą w krótkim czasie do powstania statków mających objętość ładunkową 300 tyś. m3 a nawet przekraczających tę wartość. W szczególności Gazowiec LNG ze zbiornikami kulistymi, wnętrze zbiornika gazowca ze zbiornikami kulistymi, montaż zbiornika pryzmatycznego typu IHS na gazowcu LNG, gazowiec LNG typu membranowego, struktura floty gazowców LNG pod względem konstrukcji zbiorników oraz perspektywy ich rozwoju w najbliższych latach, struktura udziału gazowców różnej wielkości w światowej flocie oraz perspektywy ich rozwoju, struktura udziału różnych typów napędów głównych na zamówionych gazowcach LNG są prezentowane w artykule.

Opis:: The subject of paper is to focus the problem of carbon dioxide emission from seagoing ships. The paper presents analysis of possibilities of fuel consumption minimizing and this way reduction of carbon dioxide emission from seagoing ships. However, The VI Amendment to MARPOL Convention concerning prevention against air pollution by seagoing ships did not take into consideration carbon dioxide emission, the importance of this problem was perceived by international organizations among others by IMO. As a result corrections in VI Amendment to MARPOL Convention were introduced thus forcing reduction of CO2 emission by seagoing ships. Among means reducing emission of carbon dioxide into atmosphere the following are mentioned: construction modifications of new built ships i.e. reduction of ship speed, optimization of main engine and propeller selection, optimization of ship hull shape, application of resistance reducing hull coatings, use of alternative (ecological) fuels and utilization of propulsion plant waste heat. In turn, for ships already in operation methods for fuel consumption and carbon dioxide reduction can be individual for each ship full monitoring of main engine operational parameters and measurement of waste heat utilization rate. According to opinion of paper authors, the minimizing of carbon dioxide reduction can be mainly achieved by utilisation of exhaust gases heat for electric power production in steam turbo alternators running in one- or two stage steam pressure systems. The analysis executed in the paper of one- and two stage steam system advantages shows that one stage steam system is more economically profitable in practice application.

Opis:: The goal of the paper is to focus the problem of emission of toxic compounds e.g. NOx, SOx and CO2 from seagoing ships to environment. The VI Amendment to Marpol Convention concerning prevention against air pollution by seagoing ships brought into practice in May 19th 2005 forced ship owners to use means for reduction of environment harmful substances emission to atmosphere. Considerable reduction of these harmful substances can be use dual fuel diesel engines for ship propulsion. Dual fuel engines are fuelled by natural gas having methane as main component. Leading producers of marine diesel engines introduced into production diesel engines DF (Dual Fuel) type. These engines can be fuelled alternatively with natural gas or with heavy fuel oil and marine diesel oil. Today the propulsion by diesel engines fuelled with natural gas is the most popular on ships carrying natural gas cargo i.e. LNG carriers (Liquefied Natural Gas Carriers). Natural gas is freight in liquid form under atmospheric pressure in temperature -163 °C. Due to heat penetration into cargo tanks, the liquefied gas evaporates. Evaporated cargo BOF (Boil Off Gas) is used as a fuel in ship diesel engines. However, dual fuel engines are used on other types of ships not only on LNG carriers. A number of seagoing ships fuelled with natural gas are now under construction. For example container ship 9,000 TEU in Japan shipyard Kawasaki Heavy Industries or container ship 14,000 TEU in Korean shipyard Daewoo Shipbuilding & Marine Engineering for company CMA-CGM. Ships fuelled with natural gas e.g. modern ferries are also built by Stocznia Remontowa Shipbuilding in Poland for Norwegian owner. Adaptation of presently operated ships for fuelling with natural gas is also considered.

Opis:: This paper describes the problem of improvement in environment protection by application "environment friendly" fuel natural gas for ship propulsion. In thepaper the most suitable type of ship main propulsion system using natural gas was take into consideration. Propulsion using Iow speed diesel engine, medium speed diesel engine, steam turbine and combined systems were taken into consideration. As a result of analysis it was affirmed that COGES (Combined Gas Turbine and Steam Turbine Integrated Electric Drive System) is the most suitable propulsion plant to be fed with natural gas in contrary to ship diesel engines which adaptation to natural gas use still is in initial condition. COGES type propulsion plant consists in thermodynamic join of gas turbines and steam turbines. Ali turbines drive generators ofmain ship power station supplying simultaneously electric power to ship main propulsion electric motors and to ship electric network as well. It is suggested to use natural gas as fuel for gas turbines. Steam turbines are driven by steam produced in boilers warmed by gas turbines exhaust gases. This way a high efficiency of ship propulsion is obtained. The simplest source of natural gas is cargo carried by LNG (Liquefied Natural Gas) carriers. The preliminary project of such a carrier fuel system is presented in the paper. In addition conditions of application, advantages and disadvantages of natural gas fuel system are discussed.
