    This study presents a method for evaluating the performance of zinc coating on methanol dual-fuel ship fuel tanks using image analysis. Methanol, a promising fuel with minimal environmental impact, is highly corrosive, necessitating the implementation of effective coating solutions.The experiment involved tensile tests on zinc-coated specimens at displacements of 3mm, 5mm, 10mm, 20mm, and 30mm, in addition to salt spray, microscopic crack inspections and Image analysis. Image analysis was employed to reduce evaluator bias and quantify damage patterns. The results demonstrated that, up to 10mm displacement, no significant damage was observed; however, cracking was evident at 20mm and above. A 10% failure threshold for coating performance was proposed.This method offers a reliable approach to assessing zinc coating durability in methanol-fueled ships and can be applied to other marine coatings
