Propeller Shaft Repair: Marine Vessel, Senegal

11th October 2024

Industry: Marine
Location: Senegal
Application: Marine Repair
Products: 101 Metal Repair Paste, 202 Ceramic Repair Fluid

The Challenge

A marine vessel operating off the coast of Senegal experienced critical vibration caused by severe wear on the main propeller shaft. The surface damage threatened both performance and long term reliability. The issue also risked increased fuel consumption, accelerated component wear, and potential downtime in service. With full shaft replacement involving substantial cost and long lead times, the client required a repair solution that could restore operational stability quickly and efficiently while avoiding disruption to scheduled operations.

The Application

To begin the repair, the worn shaft section was precision machined to a uniform 10mm depth, with undercut shoulders to ensure mechanical grip. 101 Metal Repair Paste was applied in multiple wet-on-wet passes to prevent air voids and rebuild the damaged profile. Once cured, the repaired section was re-machined to restore proper dimensions and alignment.

A final layer of 202 Ceramic Repair Fluid was applied by brush to deliver a dense, smooth surface with excellent resistance to erosion and marine operating stresses. This ceramic filled epoxy provided a long lasting barrier against wear, moisture ingress, and mechanical impact.

The Solution

This structured, multi-layer repair restored the shaft’s integrity and resolved the vibration issues without requiring replacement. The products were selected for their proven performance in marine environments, where mechanical stress and fluid exposure are constant. The ability to carry out the work without hot work permits or extended dry docking made the process faster and safer. With minimal disruption, the vessel returned to full service and the repaired shaft is now expected to remain in use for years under typical operational loading.
