- Abstract
- This PhD thesis focuses on biofouling of fishing vessel hulls and investigates the impacts of biofouling on ships’ frictional resistance “in real” conditions, specifically for industrial fishing vessels operating in the Mediterranean and the Black Sea coated with different types of paints. As part of the PhD study, face to face interviews with the fishermen were conducted in order to understand their awareness about the impact of the biofouling and the coating selections. Following that, an extensive and systematic experimental study was carried out for investigating the impacts of two different antifouling coating systems, namely foul release (FR) and self-polishing copolymer (SPC) coatings. Static immersion tests were conducted for SPC antifouling coatings. Eight different antifouling coatings were applied on immersion test panels and immersed for over a year. Biofouling accumulation on the panels was observed periodically. Next, various antifouling coating patches were applied on a fishing vessel to compare performances of the SPC coatings under the same conditions after a year of operation. Then, ship tests results were compared with the static immersion tests results. Finally, case studies were employed with the data generated from the static immersion tests for three fishing vessels operating in two different locations equipped with either trawl or purse seine. Results showed that although most of the fishermen are aware of the penalties caused by the biofouling, a significant number of fishermen have limited knowledge on the impacts of the biofouling. Furthermore, results also showed that biofouling accumulation shows different characteristics among the same antifouling coatings and among the different antifouling strategies (Foul release vs self-polishing copolymer coatings). In addition to that, ship test results showed similar results (insignificant differences) in comparison to case studies conducted in the Black Sea.
