Aside from hydrodemolition, Conjet robots are used for the paint removal on ship hulls and decks with the use of high pressure water. The process is similar to scarification of concrete, but the tools are adapted to fit the complex forms of the hulls.Sandblasting is frequently used in the ship cleaning industry to remove paint and to prepare surfaces for painting. It has shown that this is not a healthy environment which have lead to the fact that there are voices that would like to stop the use of sandblasting. The cost, in many countries, is far higher for the deposit of the sand as it is contaminated than it is to purchase the sand. the sand creates a lot of dust. So much that, in most cases, the repair and maintenance on the engines can not take place during the sandblasting operation. An alternative to sandblasting is the use of high pressure water, which is far superior from an environmental perspective. The paint residuals can be collected in a controlled way by vacuuming it directly during the removal process. Furthermore, the handling of sand is eliminated leading to reduced costs for purchase and transportation. This technology is not yet spread on the market but with the change in legislations all over the world the ship yards will be forced to find new alternatives to sandblasting. This is where the use of high pressure water comes in. The sooner ship yards realize and acknowledge this problem, the sooner they will begin the switch from sandblasting to high pressure water. With more time to adapt to this new concept and technology, a ship cleaning contractor has the chance of becoming used to the method before the changes in legislations force them. This is a possibility of being more competitive on the market. As environmental issues grow more important, shipping companies with a ”green” profile will want to look into environmentally friendly ship shards. To us, it is just a matter of time until legislations bring this technique upon ship yards all over the world.
