An Engine Room Simulator as a Tool for Environmental Education of Marine Engineers

This paper presents a possibility of using a full-mission engine room simulator as a tool for educating marine engineer officers. Basic technical data have been shown for full-mission engine room simulator Kongsberg Neptune MC90-IV which is used to educate marine engineers by the Maritime University of Szczecin. An example of classes in the simulator has been described explaining selected issues of the sea environment and its protection to the students. The exercise is about the operation of the main engine fuel supply system injected by the fuel-water emulsion to decrease the emission of toxic exhaust gases components. According to the authors, the proposed exercise in the simulator may greatly contribute to the development of conscious and responsible machinery exploitation and pro-ecological behaviour during the engine room operation. Exercise assumptions and results obtained during it have been presented together with the conclusions drawn when using the engine room simulator to create pro-ecological behaviour of marine engineers.

Basic Reliability Structures of Complex Technical Systems

In the paper the basic reliability structures of complex technical systems were described. Selected models of the reliability structure were presented. This original paper is a proposition of using reliability structures and based on them algorithms to ensure better diagnostics, maintenance and control of complex technical systems. Some practical examples of using reliability structures were indicated. The presented structures can be put into use in human-machine interfaces to inform operators about the current system condition and to automate some engineering processes and procedures concerning the system reliability.

On the Possibilities of Applying the AHP Method to a Multi-criteria Component Importance Analysis of Complex Technical Objects

The paper presents selected issues in the area of modelling a complex technical system structure. We presented the main types of a real technical system reservation. We showed selected proposals of a component redundancy description. We presented a black-box model of the system and described our own concept of qualitative-quantitative analysis of the complex technical system component importance. We also showed a possibility of applying the AHP method to a multi-criteria importance analysis. Some research achievements in this area and propositions for further development of a multi-criteria component analysis have been shown.

Is Poland an Innovative Country

Abstract The potential for innovativeness is difficult to measure, though many have attempted to do so. In order to look at Poland’s innovation potential, its current position and its opportunity to grow, compared with developing and developed countries, this study analysed the patent statistics of the Polish and European Patent Offices. Poland has been a member of the European Union for over a decade now. Therefore, we took into consideration the statistics for patent applications and grants for the last decade, up to the first quarter of 2016. The questions we wanted to answer concerned not only the technology fields that Poland patented its inventions in, but also the types of patent grantees and applicants. In order to determine why Poland is still considered to be only a moderate innovator by the Innovation Union Scoreboard, we also gathered information on Polish inventors abroad in 2015 and the first quarter of 2016, to see their number, technology fields, and types of patent grantees. Finally, we attempted to identify the main barriers that seem to inhibit Polish technology and innovation growth, despite significantly growing R&D intensities (up from 0.56 GDP and EUR 1,139 M in 2004 to 0.94 GDP and EUR 3,864 M in 2014).

On the Present State-of-the-Art of a Component Importance Analysis for Complex Technical Systems

The paper presents the present state-of-the-art of a component importance analysis for complex technical systems. We used a sea vessel as an example of the complex technical system. We showed selected statistics of ship operation losses. We highlighted a necessity of further development of importance analysis methods for machinery operation. We presented a description and diagrams of qualitative and quantitative importance analysis. We pointed out the most significant problems of complex technical systems modelling. We introduced a multi-criteria system component importance analysis. Basic criteria for a system component quality evaluation have been presented. We described some factors influencing importance of the technical system components.

Analysis of the efficiency of port container terminals with the use of the Data Envelopment Analysis method of relative productivity evaluation

Abstract The article presents a method for evaluating the efficiency of port container terminals. The research was conducted for nine European terminals which use different handling technologies. The terminals have been divided due to the level of automation of transport processes. In the efficiency research DEA (Data Envelopment Analysis) method is applied, that was previously used in studies of the relative productivity in the industry. This method allows you to multicriteria process analysis based on the properly selected production system model processing input parameters on output. Conclusions from analysis can be a ground for making a decision on organizational or investment issues.

An engine room simulator as an educational tool for marine engineers relating to explosion and fire prevention of marine diesel engines

The paper presents basic information about the prevention of explosions and fires in marine engines, with particular reference to explosions in the crankcase. It also discusses the possibility of using engine room simulators in educating marine officer engineers to prevent dangerous situations during actual marine diesel operation. Two scenarios have been shown that illustrate the developments in the case of improper operation of main bearings while the operation of an engine safety system is intact and there is lack/override/failure of safety systems. In scenario I the main engine shut down occurs and scenario II simulates an explosion in the crankcase.

R&D in Poland: Is the Country Close to a Knowledge-Driven Economy?

Abstract Poland has a strong ambition to evolve rapidly into a knowledge-driven economy. Since 2004, it has been the largest beneficiary of European Union cohesion policy funds among all member states. Between 2007 and 2013, Poland was allocated approximately EUR 67 billion, whereas for 2014-2020 the EU budget earmarked EUR 82.5 billion for Polish cohesion policy. This means that in the coming years, Poland’s R&D intensity will grow. But the question remains: is 27 years of free market economy enough to enable a country’s economy to become knowledge-based ? This paper offers an analysis of Polish R&D expenditures and investments in terms of their sources (business, government or higher education sectors), types (European Union or state aid) and areas of support (infrastructure, education or innovation). It also characterises the Polish R&D market with its strengths and weaknesses. Then, it examines the process of technology transfer in Poland, comparing it to best practice. Finally, the paper lays out the barriers to effective commercialisation that need to be overcome, and attempts to answer the question raised in its title.

Utilising elastic waves of acoustic emission to assess the condition of spray nozzles in a marine diesel engine

ABSTRACT This article presents an original method of using elastic waves of acoustic emission (AE) to assess the technical condition of nozzles in marine diesel engines. The developed method makes it possible to detect the early stages of wear by friction of the needle-nozzle pair. The phenomenon of AE and the possibility of its use in evaluating the condition of marine diesel-engine injectors are discussed. Experiments are presented in which the AEs were used to evaluate the condition of both a new injector and an injector where galling of the needle-nozzle pair is developing. The measurements were processed by time–frequency analysis and wavelet transformation.
