In naval maintenance operations, surface damage to critical gears can pose a significant risk to the reliability of the propulsion system. An interesting localized pitting repair procedure was recently carried out to repair pitting on the flank of a tooth on a Schottel transmission installed on a tugboat.

The repair was performed at a shipyard in Cartagena, Colombia, using specialized techniques aimed at:

✔️ Recovering the tooth contact surface

✔️ Restoring the gear's functional condition

✔️ Extending the component's service life without requiring immediate replacement This type of repair requires rigorous process control, as well as a detailed damage assessment to ensure that the gear's integrity and the transmission's reliability are not compromised.

Localized repairs of high-precision gears are an excellent example of how maintenance engineering can optimize costs, reduce downtime, and maintain the operational readiness of critical systems in the marine sector.
