Underwater Hull Cleaning
One of the biggest problems facing the world shipping is fouled ships hulls. Different species of marine organisms are attached to submerged hull of ships. These marine organisms act by covering antifouling paint and creating a thick layer on the ship’s hull which in time destroys and affects its optimal function.
