A large vessel in Senegal faced severe operational vibration due to significant wear on the propeller shaft. The customer sought an effective repair solution to avoid the high cost and extended downtime of a full replacement. A practical and efficient refurbishment was required to restore the vessel’s performance and ensure minimal disruption to operations.
Resimac’s Propeller Shaft Repair Solution
- Machining the damaged propeller shaft to a consistent 10mm depth for precise preparation.
- Application of 101 Metal Repair Paste to rebuild the surface and restore integrity.
- Resurfacing with 202 Ceramic Repair Fluid for a smooth, durable, and erosion resistant finish.
Application Details
The worn propeller shaft area was machined with undercut edges to ensure strong adhesion and proper surface preparation. Resimac 101 Metal Repair Paste was applied in multiple wet-on-wet layers to minimise air encapsulation, create a solid repair, and restore the shaft’s structural integrity. After curing, the excess material was machined away to achieve the correct surface profile and precise alignment. Finally, a brush application of 202 Ceramic Repair Fluid provided a smooth, hard wearing finish, ensuring durability and long term protection against operational stresses and environmental wear.
