The continuously sweating pipes on the Mexilhão Platform were suffering from severe corrosion.
The platform operators were looking for a new coating solution as their current suppliers were unable to solve the problem.
Working in humid weather conditions, combined with continuously wet pipes, ensured application of conventional paint systems would be very difficult.
Grit blasting was not permissible due to H&S concerns and there could be no operational shutdown.
Water jetting was utilised as the surface preparation method.
This was followed by two full coats of solvent-free, wet & rust tolerant epoxy coating RS 500P; which was applied directly onto the wet substrate whilst it was still in operation.
The application was successfully completed to the satisfaction of all concerned.
The Chemco system allowed the repair of the corroded pipes whilst in operation and with significant condensation on the surface.
• No grit blasting required • Wet & rust tolerant
• No humidity or dew point restrictions
• No delays due to sweating substrate
• No operational shutdown
• Significantly reduced downtime
• Reduced H&S and Fire Precaution
