OVERVIEW

The aluminium void tanks on-board Bourbon Offshore Asia’s Surfer Boat 2612 & Surfer Boat 2601 required to be refurbished as they were showing signs of deterioration.

CHALLENGE

Providing a suitable coating system capable of adhering to a aluminium surface. The tanks are located within a very small confined space only accessible by crawling through. Grit blasting and water jetting could not be utilised due to monetary constraints of the client. Working within a tight time frame also added to the difficulty of this project.

SOLUTION

The preparation method and the Chemco coating specification was the same for both Surfer boats. Utilise mechanical preparation as the surface preparation method. Apply solvent-free, wet & rust tolerant epoxy Epo-chem™ RS 500P as a primer @ 100µ DFT by roller, followed by a topcoat of solvent-free epoxy Epo-chem™ RA 500M @ 250µ DFT.

OUTCOME

This project was carried out on time with no delays. The Chemco system and the speed of the contract was to the satisfaction of all concerned.
