heal.abstract	The aim of the present thesis entitled “Antifouling Technology and Vessel’s performance” is to present the antifouling industry and the relevant antifouling systems involved, as well as to point out the influence of the antifouling systems in the daily operation of modern seagoing vessels. Taking into account the above stated aim, a complete effort is made into presenting the history of antifouling coatings and their categorization based on their chemical characteristics and their properties. More specifically, definitions are given for the basic concepts surrounding the issue of fouling and the functioning mechanisms behind the fouling process are being analyzed. The most significant antifouling systems implemented since the first fouling observations until nowadays are, also, recorded. In addition, this thesis covers the topic of the chemical composition of an antifouling coating taking in consideration its different components. More than that, the elements of the two most well-known antifouling coatings (i.e. copper-based and nontoxic fouling-release) are presented. While focusing more and more on the shipping industry and its direct relationship with the antifouling technologies, a detailed presentation is made on the necessary steps towards the proper selection and application of an antifouling coating on a seagoing vessel. The international ISO standards related to the antifouling technology, as well as the classification of antifouling coatings are also reported. Moving on, and clearly focusing on the seagoing vessels themselves, a detailed presentation on the topic of “vessel performance” is made, covering its definition and its monitoring throughout a vessel’s seagoing life. The connection between a vessel’s performance and the applicable antifouling technologies is made through the presentation of the effects of marine fouling on the frictional resistance of the vessel during sailing in various stages of its life. A detailed overview of the “vessel’s resistance” (definition and mathematical formulas) is given, as well as various examples from theoretical models and real-life examples of operational vessels, so as to observe and record the actual effect of fouling on a vessel’s performance and the subsequent financial impact for the ship-owning company. The real-life examples focus on the observation of the performance of (a) one or more vessels over time, under different circumstances, while using the same antifouling coating, and (b) similar/identical ships using different antifouling coatings. Finally, some innovative technologies and ideas around the antifouling industry and their fields of application are presented. Those innovative technologies refer to new products that have risen in the antifouling coating industry by a radical change of approach on the marine fouling issue, as well as extrinsic technologies that may prove useful in the fight against fouling. A summary of all the above as well as the relevant conclusions extracted are presented in the end of the present thesis.	en
