Opis:: Exhaust gases from engines of seagoing ships are the serious problem for environment. That is why the discussion in the matter is very important. One of means to minimise harmful substances emission to earth atmosphere is application of „ecological fuel" — natural gas or nuclear energy for ship propulsion. Natural gas is commonly used in onshore applications but is rarely applied in marine propulsion. Heavy Fuel Oil is the basic brand of fuel used onboard ofseagoing ships. Other kinds of fuel e.g. Diesel Oil or gas Oil are used on smaller ships with limited sailing range. The nuclear energy, due to high costs is used only on few types of warships and some icebreakers. A real means for minimising harmful substances in exhaust gases from ships engines is replacement of Heavy Fuel Oil by Natural gas. Nowadays, heavy oil is commonly used due to technical and logistic abilities and conservative attitude of ship owners. The necessity of improvement in the field of environment protection inclines towards wide application of Natural gas as marine fuel. Application power-plant novel type would break the traditionalism in the shipbuilding and the introduction novel generation ofshipping drives.

Opis:: Gas turbines are used as marine prime movers but the market is dominated by the diesel engines (of course turbocharged but they are still diesels). The share of gas turbines is on a level of 4-5% in the worldwide shipping. It was presented the chosen parameters of Rolls-Royce gas turbine MT30 with nominal power 36 MW or 40 MW prepared for marine utilization. It is a good example of development of marine gas turbines with the trial to eliminate the effect of ambient temperature especially on turbine load. It was discussed the significance presented data for possibility of utilization on vessels. It was indicated the advantages and disadvantages of gas turbine sharing. It was mentioned the installation problems: pressure drop in inlet and outlet ducts on the accessible turbine power and specific fuel consumption. It was discussed what important parameters ought to be known for safe turbine operation and maintenance. There is a little information lack. The gas turbine ought not to be treat as a black box. In the end, some final remarks are presented.

Tematy:: low sulphur marine fuels
ecological propulsion of seagoing ships
Opis:: Corrected VI Annex to MARPOL Convention requires from January 1st 2015 the use of low sulphur fuels on seagoing ships. The target of requirement is reduction of environment harmful substances in exhaust gases coming from marine fuels combustion. Areas of sea trade are divided into two zones: special Sulphur Oxide Emission Control Areas (SECA) for example Baltic Sea and areas outside SECA. On SECA sea areas the contents of sulphur in marine fuel should not excess 0.1% and on outside SECA the same is 3.5%. In the future i.e. from January 1st 2020, the maximum contents of sulphur in marine fuels on outside SECA areas should be 0.5%. These requirements create serious problems for ship owners operating worldwide. The first problem is considerable higher price of low sulphur fuels, which affects operational costs of fleet. The second problem is adaptation of ship engines to be fuelled with low sulphur fuels. At present, the heavy fuel oils being in common use on ships does not fulfil environ protection requirements. As a result, the use of new grades of marine fuels becomes necessity to fulfil environment protection requirements as well as price requirements to keep merchant fleet operation profitable. The wide use of “ecological fuel” i.e. natural gas as marine fuel is expected. The type of ship propulsion plant, which can be used in the future, will effect on the course of marine energetic plants development. The development of hybrid propulsion, electric propulsion, diesel engines fuelled with natural gas and turbine propulsion driven by natural gas. The paper includes proposal of combined turbine propulsion plant fuelled with natural gas, which according to authors can be leading type of marine propulsion plants in the future.

Tytuł:: Usefulness assessment of standard measuring instruments installed on sea-going ships to perform energy measurements

Tematy:: standard measurement instrumentation

accuracy of measurements
Opis:: The presented work is a contribution to discussion on usefulness of application of measurement instrumentation used on sea-going ships for energy measurement and scientific research purposes. Contemporary sea-going ships are equipped as a rule with up-to-date measurement instrumentation usually based on electronic data processing and computer technique. These authors have made many times use of such instruments in their research work. This way it was not necessary to install any special instruments, that significantly reduced measurement cost. In such cases to obtain a sufficient accuracy of measurements constitutes a crucial problem. In this paper was presented an analysis of measurement errors of some operational parameters of ship and its main propulsion system, elaborated within the frame of the KBN research project no. 9 T12D 033 17. Results of the analysis confirm usefulness of the standard measurement instrumentation installed on ships, and its sufficient accuracy.

Tematy:: natural gas ship propulsion
COGES propulsion system
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.
