Marine (MRNE)



Ships and Offshore Structures (SOS)


Customer Location:

Dockyard, Bulgaria


Application Date:

February, 2009


Application Situation:

Oversized housing and keyway of rudder pintle.



Keyway and rudder pintle housing were oversized due to erosion corrosion and impact.



Belzona® 1111 (Super Metal)

Belzona® 1221 (Super E-Metal)



Cast Iron


Application Method:

Application procedures were made according to Belzona Know-How System Leaflet SOS-3. The oversized housing and keyway were rebuilt  using the rudder pintle with a false key as former. Belzona® 1111 was used for the main repair and Belzona® 1221 was used to fill some voids along keyway.


Belzona Facts:

The repair was done on-site and completed in a few hours. In this situation conventional repair by welding and then machining was considered to be time consuming, complicated and too expensive.
