I know that there is different anti-fouling paints and their prices. But, I am looking to find more additional information about the real costs of anti-fouling measures such as how much cost to remove the ships and the cleaning. I also know that some ships do partial cleans without removing them from the water. But, I dont know the costs of those, how often or what kind of ships do that. I have not been very successful on Internet search. I am planning to do some surveys to the industry, but It would be good to have other sources of data also.
