To meet the growing demand for underwater ship care, specialist ship repair and maintenance companies are now expanding their services to facilitate shipowner requirements in more and more locations. In the last few months, divers from Belgium-based Hydrex, for instance, have carried out more than 25 propeller modifications around the world, primarily to restore the propellers' balance after blades suffered ice or collision damage. A ship with bent or cracked propeller blades might experience severe vibrations while sailing, potentially resulting in classification societies demanding repairs before the vessel is allowed to sail on. But by straightening the blades or cropping them, the propeller's balance can be easily restored.
