Opis:: The frequent cause of ships’ detentions by port authorities are abnormalities of ship power plant functioning. Each extended ship lay time in port results in waste of ship operating time thus costs rise to shipowners. This is connected with improper ship power plant management. In order to avoid this, a ship engineer should have at his disposal computer aided system supporting him in managing of ship power plant. Such a system can be worked out on condition that mathematical formula which represents the decision – making process of an engineer has been built. The present work shows approache to the problem according to the situation in which the engineer is made to take certain decisions. In formulation of the most substantial operating states of a ship like lay time in harbour and sea voyage the ‚knapsack algorithm’ was applied. For both approaches objective function was formulated.

Opis:: During their stay in harbours the ships generate the electric energy and heat for their needs most frequently by use of their own power and boiler plants through Diesel generating sets and oil fired boiler. The operation of this machinery causes the toxic compound emission to the atmosphere. In this article the possibilities are presented of limiting this emission through such activities as supplying the ship with the energy from the shore power network, from barge-situated power plant provided with the Diesel generating sets supplied with LNG, and in case of the boiler plant through the application of the liquid or solid biofuel. There are also presented some selected results of the simplified comparative analysis of the emission levels with the various methods of generating the electric energy and heat during ship’s stay in harbour.

Tytuł:: Energy - time method for assessment of main diesel engine operation
Autorzy:: Rudnicki, J.

Data publikacji:: 2007
Wydawca:: Instytut Techniczny Wojsk Lotniczych
Tematy:: ship power plants

Opis:: This paper presents a development of the known qualitative method for assessment of engine operation, applied to ship main diesel engine as an example. According to this interpretation engine operation can be presented as a physical quantity. In this aspect, based on the selected functional system of the engine, was assessed usefulness of the quantity for description reliability features of the system. To the analysis was applied Poisson's uniform process which made it possible to elaborate a model of run of worsening the considered system's operation taken as a random process of identical independent decreases of energy efficiency within a given time interval. The presented method is a valuable supplement for description reliability features of ship main engine what is important for realization of shipping tasks by sea. Additional advantage is versatility which makes that it can be applied to reliability analysis of any ship device or ship energy subsystem. Classification of the engine serviceability states with taking into account the assessment of its operation in energy-time aspect, schematic diagram of lubricating system of RTA48-TB engine and values of lubricating oil parameters in steady conditions for the engine load, graphical presentation of lubricating oil cooler operation graphical interpretation of the decreasing of oil cooler efficiency are presented in the paper

Opis:: This paper presents application of fuzzy logic to assessment of degree of hazard to ship power plant operator. For the assessment a system of computer-aided identification of hazardous zone within ship power plant, was used. The system’s variables representing the subject-matter knowledge in safety design area were transformed into fuzzy sets by means of appropriate linguistic variables and membership functions. The assessing of safety level of operator with the use of fuzzy inference was performed by means of an expert system programmed in the PROLOG LPA language.

Opis:: In order to discuss the simulation model of the ship transmission line and the state of the transmission line, an early fault model is built according to the evolution principle of the short circuit fault of the transmission line and combining with the fault characteristics of the early fault. A small distributed ship transmission line system is built in MATLAB/ Simulink. Then, combined with the constructed fault module, the original short circuit module, and the load module, the various states (normal state, early fault state, severe early fault state, short circuit state) of the ship transmission line are stimulated, and the features of voltage signal in each state is analysed. It is concluded that, due to the normal operation of the ship transmission line system, the variation characteristics of the flow signal and voltage signal caused by the sudden load mutation, that is, the sudden load and the sudden increase load, are very similar to the changes caused by the early fault. Therefore, in order to find a more accurate early fault detection method, the state is divided into normal state, sudden load state, sudden increase and sudden decrease load state.

Opis:: Attempts to increase the profitability of SPI work inevitably result in the necessity of increasing the degree of utilizing waste heat from exhaust gases of marine main engines (ME). This analysis of possible use of turbo-generators is based on a comparison of available heat of ME exhaust gases with expected loads of ME, steam and electrical power consumption.

Tytuł:: Assesment of operation of ship main diesel engine using the theory of semi-Markovian and Markov processes
Autorzy:: Rudnicki, J.
Powiązania:: https://bibliotekanauki.pl/articles/245616.pdf
Data publikacji:: 2009
Wydawca:: Instytut Techniczny Wojsk Lotniczych
Tematy:: operations
ship power plant
diesel engine
semi-Markov processes
Opis:: Operation of ship propulsion system is associated with realization of definite operational goals. If to elements of the system the operational reliability strategy could be applied, the situation would be very simple as existing conditions would unambiguously determine application of means being on hand. However decision to reject application of the strategy (even if hypothetical) becomes obvious with a view of necessity of ensuring an acceptable level of safety to ship and environment as well as presence of associated formal and legal limitations. Therefore complexity of operational reality makes that means intended for operation may be used in various ways. Objectivity and rationality in making decision, assumed optimal in given conditions, forces to apply an evaluating (quantitative) approach to the problem, hence to search for such their parameters (indices) which, in a given decision situation, can be deemed most adequate. To precisely determine the task it is necessary to specify also its duration time, apart from conditions in which it will be realized. When considering propulsion engine, i.e. the main element of ship propulsion system, especially important becomes not only the problem which amount of energy could be at one's disposal but also within which time interval it could be delivered. Therefore apart from applying the commonly used reliability indices, it seems sensible to consider the operation in such evaluating approach as it could be determined by energy and time simultaneously.
