Grey Water Tank Refurbishment

The grey water tanks on-board a grand class cruise ship had severely corroded and required to be refurbished.

The project had to be completed whilst the vessel was at sea. There could be no disruption to the normal operating services of the vessel. Grit blasting was therefore not permissible and a solvent-free solution had to be utilised.

The grey water tanks were water jetted to prepare the surface. One stripe coat and one full coat of solvent-free, wet & rust tolerant epoxy Epo-chem™ RS 500P was then applied. This was followed by one stripe coat and one full coat of Epo-chem™ RA 500M.

Substantial time and cost savings were achieved by completing this project whilst the vessel was at sea. The downtime of the tanks were significantly reduced as the products can ‘continue to cure’ underwater.

• Solvent-free
• No grit blasting
• No humidity or dew point restrictions
• No re-coating limitations
• No dry-docking requirements
• No disruption to passengers or crew
