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.
