    Hydrex restores balance to over 25 propellers with blade repairs across the globe

    30/06/2011

    Over the last months Hydrex diver/technicians have carried out more than 25 propeller repairs around the world. Our divers were active in the Netherlands, Greece, Denmark, Spain, Italy, Panama, Singapore, the U.S.A. and many other countries. All operations were performed to restore the propellers’ balance. They were brought back to as close to their optimum performance as possible after the blades had suffered damage due to collisions with ice or debris.

    By taking advantage of the in-house developed cold straightening technique, damaged blades can be straightened underwater, allowing the ship to return to commercial operations without the need to drydock. Optimum efficiency of the propellers can be restored by bringing the blades back close to their original form.

    If straightening is not an option, the affected area on the blade will be cropped to restore the hydrodynamic balance. This is done to achieve the greatest possible efficiency for the vessel. This kind of repair is carried out with the propeller blade cutting equipment that was also developed by the Hydrex research department.

    Hydrex has been cropping propellers since 1985 and straightening them since 2000.
