OVERVIEW

The fore peak ballast tank of a towage vessel required to be converted into a potable water tank. The tank was generally in good condition with minimum corrosion in a few areas.

CHALLENGE

The tank required to be coated with a system which was certified for potable water applications. The new coating system also had to be compatible with the existing tank lining.

SOLUTION

HPWJ (500 bar) and mechanical preparation (St 3) were utilised as the surface preparation methods. One primer coat of solvent-free, wet & rust tolerant epoxy Epo-chem™ RS 500P was applied. This was followed by two topcoats of solvent-free, wet tolerant, glassflake epoxy Epo-chem™ RA 500M.

OUTCOME

The work programme was completed in 5 days; much quicker than would have been possible utilising grit blasting and conventional paint systems. Substantial time and cost savings were therefore achieved.

BENEFITS

• Solvent-free
• No grit blasting requirements
• Compatible with other protective coating systems
• Significantly reduced H&S and Fire Hazard
• No humidity or dew point restrictions
• No re-coating limitations
