Ships and Offshore Structures (SOS)

 
 

Customer Location:

Dockyard, Bulgaria

 
 

Application Date:

November, 2009

 
 

Application Situation:

Bow thruster of cargo vessel

 
 

Problem:

Erosion/corrosion effects made severe pitting damage to the whole bow thruster and supporting pillar due to bad cathodic protection.

 
 

Products:

Belzona® 1311 (Ceramic R-Metal)

Belzona® 1321 (Ceramic S-Metal)

 

Substrate:

Cast iron

 
 

Application Method:

Belzona Facts:

Replacement of the badly eroded bow thruster body was planned for the next dry-dock but immediate replacement was not an option due to delivery time constraints. Belzona was chosen for its durable, fast and inexpensive application. The whole repair was done within a 48 hour period, restoring an even surface profile with additional protective coating for long erosion/corrosion resistance.
