Abrasive blasting and coating using customised scaffold solutions

Abrasive blasting and coating the internal walls of a 40 metre diameter tank required a customised scaffold solution

This tank has an external floating roof which makes it difficult to manoeuvre a mobile scaffold around on. With the help from the scaffold company and engineers we designed a drop scaffold from the kerb angle. We were able to complete the project safely and in a timely manner. Full encapsulation was required with dust collection. With this scaffold system we were able to encapsulate the area to create negative pressure, meaning we prevent dust escaping to close houses.

This Jet fuel storage tank required the entire coating removal average thickness was 850microns. We used 2 boom lifts which were driven through a door sheet to access the tank 4 blasters working inside using radio communications to help navigate the dusty environment.

Using UHP to remove coatings on the external of a 60meter cone roof tank remove and capture of waste so that workers can continue to work around us. The Vertidrive 4 uses powerful magnets to grip to the steel, this unit crawls up walls. The water and paint flakes are vacuumed back to the ground and disposed of as bulk waste.

Restoration of a fire water tank in Gladstone. Here, we entered the tank and cleaned the growth and mud from the internal. Then we made a temporary roof on the tank and abrasive blasted the walls and floor to class 2.5. Thereafter, we applied 500microns of Interzone 954.
