PROPERTIES OF MICROBIOLOGICALLY INFLUENCED CORROSION AND ITS IMPACT ON MARITIME TRANSPORT

U ovom završnom radu obrađena je tema svojstva mikrobiološki uvjetovane korozije i njezin utjecaj na pomorski promet. Na početku rada razrađeno je samo značenje riječi korozija, te izvršena klasifikacija korozijskih procesa. Nakon toga, navedeno je samo značenje mikrobiološke korozije, opisani mikroorganizmi povezani s mikrobiološkom korozijom i izvšena je njihova klasifikacija, objašnjeno je zašto mikroorganizmi vole živjeti u biofilmovima, dani su mehanizmi mikrobiološke korozije, te je opisana problematika nedostatka znanja i budući trendovi u istraživanju. Naglasak ovoga rada je zaštita brodskog trupa od obrašatanja i korozije što je i opisano u zadnjem djelu rada. Dani su i neki povijesni aspekti zaštite, te opisani načini i metode zaštite od mikrobiološke korozije koji se danas koriste.In this final paper, the topic of the properties of microbiologically conditioned corrosion and its impact on maritime transport is discussed. At the beginning of the paper, the meaning of the word corrosion was elaborated, and the classification of corrosion processes was performed. After that, the meaning of microbiological corrosion is given, microorganisms related to microbiological corrosion are described and their classification is performed. Why do microorganisms like to live in biofilms are explained, mechanisms of microbiological corrosion are given, and the problem of lack of knowledge and future research trends is described. The emphasis of this paper is the protection of the hull from overgrowth and corrosion, which is described in the last part of the paper. Therefore, some historical aspects of protection are given. The ways and methods of protection against microbiological corrosion that are used today are described
