Optimisation of the Topping-Up Process of Lubricating Oil in Medium-Speed Marine Engines

In this paper, we examine the problem of optimising the process of topping up lubricating oil in medium-speed marine engines. This process is one of the methods that can be applied to improve the properties of lubricating oil. The amount of fresh oil added to lubricating oil system always balances its consumption, but the method used to top up depends on the marine engineer. Small amounts of fresh oil can be added at short intervals, or large ones at long intervals, and the element of randomness often plays a significant role here. It would therefore be valuable to find a method that can help the mechanical engineer to choose the right strategy. We apply a multi-criteria optimisation method for this purpose, and assume that the criterion functions depend on the concentration of solid impurities and the alkalinity, which are among the most important aspects of the quality and properties of lubricating oil. These criterion functions form the basis for multi-objective optimisation carried out with the use of the MATLAB computer program.

Sangallo, Vignola, Palladio and the Roman «Accademia de lo Studio de l’Architettura».

Bernd Kulawik is a trained marine engineer who studied physics, musicology and philosophy at the Technical Universities of Dresden and Berlin. MA thesis in 1996 about Monteverdi’s «Seconda Pratica». PhD in 2002 with a dissertation about drawings in the Berlin «Codex Destailleur D» for Antonio da Sangallo the Younger’s last project for St. Peter’s in Rome. Since 1988 he worked in research libraries and institutes in Berlin, Rome, Berne, Einsiedeln and Zurich, mostly as developer for database projects. Since 2013 he could take up his research about the study of ancient architecture in Renaissance Rome which led to the rediscovery of the forgotten «Accademia de lo Studio de l’Architettura». This academy almost completely realised Claudio Tolomei’s ambitious program from 1542 formerly believed to be unrealisable. Other research interests are the history of philosophy, Renaissance music and the epistemic and technical preconditions as well as long-time perspectives of the Digital Humanities.

Peculiarities of marine engineers’ image formation according to the results of component-structural analysis of vocational training in marine institutions of higher higher

The structural components of the future marine engineers’ professional image have been identified in the article: motivation-targeted, content-oriented, reflective and communicative. Thus, under the motivation-target component, the authors describe professional motivation, satisfaction from material needs and a motive for personal image. In accordance with the requirements of the STCW Convention, at the operation level, the content-oriented component is indicated by sufficient future marine engineers’ competence in information technologies alongside their skills to use them. It has been determined that according to the communicative component, a bachelor-marine engineer with a high level of readiness for intercultural communication is more competitive in the labour market and has significant advantages as follows: can recognise and overcome barriers to intercultural communication; can anticipate and quickly resolve various conflict situations; can creatively use his / her knowledge in profession-related activities as well as ethical norms and rules of conduct with representatives of other cultures. It has been proved that in terms of forming the reflective component of the marine engineers` professional image, it is expedient to cover these components: sufficient theoretical baggage, which is formed by the future marine engineer within training and self-education; bringing practical skills of performing basic actions on ship equipment control to automatism; the ability to analyse actions, make decisions in dangerous and emergency situations, the ability to self-analyse their actions; the ability to draw conclusions based on the results of analysis and work experience, etc. The authors of the article pay attention to the urgency of the problem and the need to provide the educational process with scientific and methodological recommendations aimed at the formation of the professional image of marine engineers, which provides an integrated approach to solve the problem under focus, to involve academic staff and highly qualified specialists of seagoing vessels.
