Maintenance management of marine power systems supported by risk analysis

Abstract: This article presents the complexity of maintenance of ship power system elements with a view to ensuring its safe operation. Possible maintenance strategies have been shown, indicating those which are most frequently used on ships and their application has been justified. Factors limiting application of maintenance strategies have been listed while indicating insufficient use of risk analysis. Formal and legal aspects of maintenance management have been discussed including the regulations on maritime environment protection which are presently in force. Methods of risk identification of ship power system elements have been studied pointing at the feasibility of the Expert Method. The re-sults of studies on the extension of periods between overhauls of current generating units of engines operating on Ro-Ro type ships have been shown and they confirm that the Method is useful at sup-porting the management of maintenance of a ship power system.

Is design thinking useful in educating engineers ?

Abstract: The paper presents the design thinking (DT) methodology together with objections raised against it and discussion on them. Example wicked problems to be solved by means of DT have been shown. It has also been pointed that the DT application might be effective in an appropriately designed and prepared creative space being a component of a creative working environment. A traditional class has been compared to the class led in a creative space. An example university structure referring to and containing a creative space has been shown. Finally, the necessity for multidisciplinary education of engineers with the practical use of heuristic methods has been discussed.

Using of soundscapes in acoustic environment quality of towns – proposal of research

Abstract: Quantitative assessment of the exposure of the inhabitants to noise does not comprise the influence of qualitative factors of perception of sound. Basically, the research on qualitative aspects of noise is conducted with the use of questionnaires. New approach to designing acoustic environment assumes taking into account objectivised features of noise perception combined with quantitative assessment of exposure. The key aspect in the new approach is representation of subjective assessment of reception of acoustic impressions by the inhabitants in the objective way. The starting point for development of the new approach is the use of idea of sound landscapes for the needs of shaping the quality of acoustic environment.

Modern methods of regeneration of used parts of machines

Abstract: The article presents modern methods of regeneration of worn machine parts. Using in theme composites , which have not inferior mechanical properties, and in many cases better, improved compared to the previously used conventional methods. Regeneration technologies, using these materials, allow to recover faster the appropriate performance characteristics of regenerated parts of machines. Technology use of composites does not change the properties of the surface layer of material to which it is applied, as it happens, for example, during welding. Also, the cost of regeneration is lower in comparison with traditional methods. For this reason, the method of regeneration is increasingly being used in various industries.
