The size and location of the ferry meant this was always going to be tricky job. We needed to prevent any debris escaping the work area and contaminating the surrounding environment, in particular the Murray River.
Scaffolding was set-up around the perimeter of the ferry which was then covered with heavy duty monoflex fabric. Once the containment was secured, the Swart-owned 42,000cfm dust collector was positioned to capture all debris from the containment.
The setup of the containment and dust collector was successful in preventing any debris from escaping the work area and entering the surrounding environment including the Murray River.
After completing abrasive blasting and DPTI works, it was time to carry out the painting. The majority of the work involved using a two-component, polyamine‑cured, epoxy mastic system whilst a few other areas, due to their nature, required an additional top coat to keep them in optimum condition. Before every full coat, a stripe coat was carried out to all the difficult to reach areas of the ferry to ensure the required thicknesses were achieved. A representative of the paint manufacturer inspected the work as it was being carried out, to verify the surface preparation and coating application was to specification. After each component of the systems was applied DFT readings were recorded to ensure the coatings had been applied in line with the specification provided by both DPTI and the manufacturer.
This project was carried out over summer when temperatures rose to over 40˚C. Worker safety was paramount at all times, especially when working in containment and the interior of the ferry. When in the containment, all workers wore air‑fed blast helmets and face masks. When required, the air lines to workers were cooled down to ensure their wellbeing. A spotter was located outside the containment at all times to ensure worker and environmental safety. Even through these tough conditions, the work was completed on time and on budget.
