A heavy-load carrier docked at the Port of Palm Beach, FL, was grappling with persistent vibrations at higher RPMs, raising concerns about potential propeller damage. The client needed an immediate solution to restore the vessel’s performance and operational efficiency. Subsea Global Solutions, already on-site for propeller polishing and hull cleaning, quickly adapted to expand the project’s scope to address the newly identified issue.

Our Solution

A skilled 4-person dive team, led by trained propeller technicians, began by conducting a thorough assessment. Upon inspection, the Subsea Global team identified significant damage to the propeller blades. Using precision tools, they measured blade deflections, sectional losses, and stress risers, mapping the damage directly onto the propeller blade drawings. This meticulous process ensured adherence to class rules and provided the necessary data to design an optimal cropping repair strategy.

With the damages plotted, the technicians calculated precise cut lines, prioritizing the preservation of the propeller’s original diameter and maintaining ISO 484/1 mass imbalance tolerances. The team then executed a precise cropping procedure, carefully removing the damaged blade tips while restoring balance and functionality to the propellers.

The operation was completed without delaying the vessel’s port call. Subsea Global worked efficiently across two shifts: the first for propeller polishing and hull inspection, and the second for vertical side cleaning and propeller repairs. This ensured the project remained on schedule, allowing the vessel to resume operations without delay.

The repairs were a resounding success. The client reported a complete resolution of the vibration issues, with the vessel restored to optimal performance. Reflecting their satisfaction, the client remarked:

“Excellent. All the vibration is gone. Thank you!”
