Abstract

The article presents the methodology and algorithm for determining the efficiency of a ship’s energy system, which can be helpful at both operation and design stage. Knowledge of the methodology discussed here and the definitions of a ship’s energy system’s efficiency may be particularly useful for operators, as particularly complicated energy conversion chains exist on specialized units, such as fishing vessels, which have many devices that can be driven by different types of engines and transmissions. Proper disposal of energy streams allows for their optimal use and for a reduction in fuel consumption, whose cost constitutes the largest share of the vessel’s operating costs.

Abstract

The approach adopted in this paper focuses on the faults prediction in asynchronous machines. The main goal is to explore interesting information regarding the diagnosis and prediction of electrical machines failures by the use of a Bayesian graphical model. The Bayesian forecasting model developed in this paper provides a posteriori probability for faults in each hierarchical level related to the breakdowns process. It has the advantage that it can give needed information’s for maintenance planning. A real industrial case study is presented in which the maintenance staff expertise has been used to identify the structure of the Bayesian network and completed by the parameters definition of the Bayesian network using historical file data of an induction motor. The robustness of the proposed methodology has also been tested. The results showed that the Bayesian network can be used for safety, reliability and planning applications.

Abstract

The paper reviews the performance measurement in the domain of interest. Important data in asset management are further, discussed. The importance and the characteristics of today’s ICTs capabilities are also mentioned in the paper. The role of new concepts such as big data and data mining analytical technologies in managing the performance measurements in asset management are discussed in detail. The authors consequently suggest the use of the modified Balanced Scorecard methodology highlighting both quantitative and qualitative aspects, which is crucial for optimal use of the big data approach and technologies.

Abstract

The paper presents a comparative analysis of non-destructive testing methods used in the assessment of welded joints. The authors describe the methodology of conducting tests on welded plates using the vibration method. On the basis of the FFT analysis of responses from accelerometers, spectral characteristics were calculated, and then used along with statistical measures to develop a comparative method in non-destructive testing of welded joints. This method will make it possible to quickly and easily distinguish plates with non-defective welded joints from plates with faulty welds. The paper presents test results for a non-defective plate weld (sample no. 2202), a plate with defective edge fusion (sample no. 2127) and one with a cracking along the entire sample length (sample no. 2132). The article points out the limitations of the proposed method and the need for further research

Abstract

The purpose of the underlying paper is to highlight the significance of specialist and diploma-related apprenticeships at the bachelor degree studies provided by the technical university. The evaluation of the quality of apprenticeships was conducted among the students of the Economy, Engineering and Transport Faculty of the Maritime University of Szczecin (Poland), for the study directions Production Management and Engineering (Polish: ZiP), Logistics (L) and Transport (T). The research methodology was based on questionnaire form, statistical analysis of results reliability and the analysis of literature. The results of the conducted research unequivocally indicated a need to introduce changes to the organisation of the apprenticeships, as this area determines the quality of engineers practical education and influences their professional competences.
