The owners of a General Cargo vessel consulted FN Diving regarding heavy vibrations of the propeller.
FN team attended the vessel for an underwater inspection while offloading in Rotterdam port.
The underwater inspection revealed 2 damaged propeller blades due to ice damage on a 5200MM Propeller.
In order to assure a minimum delay for the vessel, the decision was made to crop the damage in a way to maintain the propellers hydro-dynamic requirements.
After consulting our propeller repair partner a repair plan was made allowing FN Diving to repair our customers propeller on site within the vessels schedule.
By trimming the vessel the damaged tip surfaced and was cropped off dry, as well as the opposite blade tip in order to balance the propeller.
Operations started directly, after cargo ops the FN Diving team was ready to start immediately with the repairs.
Within only 7 hours all blades were cropped and hydro-dynamically reshaped, allowing the vessel to continue her voyage.
The precise and well communicated operation was possible due to a smooth cooperation between the FN Diving team, the ships staff and our propeller repair partner, resulting in a cost and time effective repair for the vessel.
