The crew of both ships had noticed that the engine was overloading. Damaged propeller blades will have a performance below average. The engine will have a higher work load. This results in increased fuel consumption and added stress.
By taking advantage of the in-house developed cold straightening technique, damaged blades can be straightened underwater. This allows a ship with a damaged propeller 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. This was done by one of our teams on the cruise ship in Tenerife.
If straightening is not an option, the affected area on the blade will be cropped. By doing this the greatest possible efficiency is achieved for the vessel. This was the case for the vehicle carrier in Antwerp.
