Hull Antifouling and Vessel Water Sanitation Treatment

Vessel Sanitation program water treatment functions well on most ships.  Every ship at sea must deal with the wastes produced by the passengers. If something goes wrong with the system, as it did in two famous cases in 2013, it brings up many health concerns. If the passengers endure these conditions for a long time, it may result in passenger refunds, new trips and many other items that cause a cruise line to lose money. Losing money is nothing any business wants to endure. If they must endure it, they want to minimize the impact it has on their business and their reputation.

The World Health Organization publishes its own guidelines on how to maintain these systems. As long as the owners follow these guidelines, they can expect few problems. Minor problems will arise from time to time, but technicians and sanitation engineers can address them.

Any vessel sanitation program water treatment must eventually turn the water back out to sea.  The water should be as clean as it was when the vessel took it form the sea. The hull of the ship must be prepared to deal with the damaging nature of the product. 

Salt water has corrosive properties of it own. When the ocean waters meet with a conducive environment, dangerous organisms can form on the side of the vessel. Barnacles, one of the best known examples from the age of wooden ships, had to be scraped off the vessel manually. Now, a process known as hull antifouling can keep the barnacles or other damaging organisms away from the ship. The process normally involves using a special type of paint. Applying the paint to the bottom of the ship creates a hostile environment for many of these organisms. As with any other paint, it must be reapplied on a regular basis.
