Abstract

By producing drinking water on a ship, seawater is led to a storage area where the seawater is treated in a reverse osmose process, such that drinking water is provided. To secure that the seawater left after being treated in the osmose do not contain unwanted invasive species that is led back to the sea, it is secured that the salinity after being osmose processed is so high that living life is made impossible. (70 ppt or higher), Appropriate the drinking water can be placed in the ballast tanks on the ship or other tanks, or alternatively on the ship in plastic bags, being positioned in the ballast tanks or in other tanks, other places on the ship.
