Coatings in water ballast tanks

Tema i glavni cilj ovog rada je obraditi sustave premaza u tankovima balastnih voda. Cilj rada je predstaviti osnovne korozivne procese, vrste premaza u balastnim tankovima, načine aplikacije, provjere ispravnosti premaza kao i najnovije standarde za zaštitu balastnih tankova protiv korozije. Rad je podijeljen na nekoliko dijelova gdje se prvo obrađuje pojam korozije i osnovni mehanizmi koji uzrokuju koroziju. Nakon toga dat će se pregled povijesti uporabe materijala na brodovima, a pogotovo na području balastnih tankova. Glavni dio rada posvećen je zaštiti balastnih tankova što podrazumijeva detaljnije objašnjenje materijala koji se upotrebljavaju za zaštitu, načine pripreme površina, načine aplikacije, vrste defekata, kao i uređaje i metode za ispitivanje kvalitete zaštite.The topic and the main goal of the thesis is to provide a detailed overview of the coating systems in ballast water tanks. The paper will present the basic corrosion processes, types of coatings in ballast tanks, methods of application, checking the suitability of the coating as well as with the latest standards for protection of ballast tanks against corrosion. The thesis is divided into several parts where the concept of corrosion and the basic mechanisms that cause corrosion are first mentioned. After that, it provides an overview of the history of the use of materials on ships, and especially in the field of ballast tanks. The main part of the thesis deals with the protection of ballast tanks, which includes a more detailed explanation of the materials used for protection, methods of surface preparation, methods of application, types of defects and devices and methods for testing the quality of protection
