Case Study—Based Overview of Some Contemporary Challenges to Power Quality in Ship Systems

The content of this paper consists of a presentation and discussion on a case study-based overview of some selected challenges dealing with a problem of power quality on ships. As a consequence, the theoretical considerations are aided by experimental results based mainly on the author’s research team experience and achievements. Two basic aspects, assessment and improvement of power quality are taken into account. In the process of power quality assessment, the existing ambiguities are analyzed and discussed, after that the undertaken measures and challenges to overcome them are presented. The ways of improving of power quality on ships are described and analyzed in two layers: technological solutions and the staff competences. Expectations and challenges for the future based on developments of both, legal and professional aspects are focused on the key question: how to reduce a risk of ship accidents. Finally, the future works as well as the concluding remarks are formulated and commented on.
