Hydrex Performs Underwater Propeller Blade Straightening
In April, a diver/technician team performed propeller blade straightening operations on two vessels at anchorage in Kalundborg, Denmark. First the bent blades of a 225–meter bulk carrier were restored. The team then straightened the damaged blades of 158-meter reefer in the same location. By taking advantage of the in-house developed cold straightening technique, damaged blades can be straightened underwater. This allows a ship to return to commercial operations without the need to drydock. Optimum efficiency of the propellers can be restored by bringing the blades back to their original form.
