Belzona 1111 (Super Metal)

Problem: The Tugboat had sustained major damage during a dock manoeuvre. This resulted in a dock bumper perforating the external wall at the rear of the boat. This subsequently damaged the supports of an internal vessel storing a fire-retardant substance.

Application Situation
A tugboat used at the port in Casablanca to tow ships into the port and dock.
Application Method
The rear necessitated an external rebuilt of the perforated wall using Belzona 1111, it was then protected against corrosion using Belzona 5811. The internal vessel required internal reinforcing of its supports using Belzona 1111 to give strength and prevent potential leaks, the repair area was then coated with Belzona 5811 to protect against corrosion. The application was carried out in accordance with Belzona System Leaflet SOS-01 and SOS-02
Belzona Facts
The tugboat had been placed in a dry dock and therefore needed to be repaired quickly so as to minimise cost. The alternative would have been to weld the rear wall as well as add supports to the internal vessel. The confined area inside would have made the hot working extremely difficult as well as distort and leave the potential for micro-fractures to form. Due to the Belzona solution the repair was done in 4 hours and back in service 2 days later.
