Belzona Protects Fast Ferry Bow Thrusters From Cavitation



Marine (MRNE)


Áreas Know-How:

Ships and Offshore Structures (SOS)


Cliente / ubicación:

Scandinavian Fast Ferry operator


Fecha de aplicación:

January 2002


Situación de aplicación:

Bow Thrusters from a 900 Passenger High Speed Service Ferry capable of 38 knots.



Cavitation problems had manifested themselves in the Port and Starboard Bow Thruster Tunnels. Annual repairs had been attempted with glass flake coatings and Belzona® 1341, but none had been ideal allowing metal loss to continue in the tunnel.



Belzona® 1111 (Super Metal)
Belzona® 2141 (ACR-Fluid Elastomer)





Método de aplicación:

Following removal of the existing coatings Belzona® 2141 was applied in accordance with a modified version of SOS-1 and SOS-2.


Hechos Belzona:

Subsequent annual inspections have shown the Belzona® 2141 to provide outstanding cavitation protection. After nine (9) years in service the Belzona 2141 remains in excellent condition apart from a few mm² of mechanical damage. The client is extremely pleased with the application which has allowed them to extend the annual docking cycle to a bi-annual one
