The ballast, diesel fuel and potable water tanks on an offshore platform required a full refurbishment after the existing coating systems had failed.
The ballast tanks had previously been coated in Eureka (soft coating). The Eureka had to be completely removed before the new coating system could be applied. The new coating system also had to be NSF Certified for potable water applications.
The Eureka coating was scraped off before the surface of the ballast tanks were prepared. All of the tanks were grit blasted to Sa 1 standard and then HP fresh water washed.
One stripe coat and one primer coat of solvent-free, wet & rust tolerant epoxy Epo-chem™ RS 500P was applied, followed by one topcoat of solvent-free, wet tolerant, glassflake epoxy Epo-chem™ RA 500M.
The project was successfully completed on time, with no delays. The same multi-purpose solvent-free, wet & rust tolerant coating system was utilised for all the tanks, resulting in less coating wastage and making the application easier for the contractors as they only had to use one coating system for all tank-work.
Using this system also ensured that the H&S and fire hazards were significantly reduced. The system utilised is also NSF Certified and FDA Approved for potable water applications.
The benefits achieved by utilising this revolutionary system:
- Solvent-free (odourless) solution
- Increased applicator safety
- No disruption to working platform
- Surface preparation flexibility
- One coating system for all tank-work
- No humidity or dew point restrictions
- No recoating limitations
- Reduced H&S and Fire Precautions
- Substantial time and cost savings achieved
