CASE STUDY
Ballast Tank Refurbishment
OVERVIEW
The Canary Wharf pier located in central London required to have its ballast tanks refurbished as they were suffering from corrosion damage. This project was completed by Wood Group.
CHALLENGE
With over 100,000 people working daily in Canary Wharf, there could be no disruption to this transport service or nearby restaurants, hotels and office buildings. Grit blasting and the use of conventional paints were therefore not permissible and an alternative solution had to be sought. The coating system specified also had to offer long-term, maintenance-free protection as regular maintenance would be an inconvenient and expensive process.
SOLUTION
Water jetting was utilised as the method of surface preparation. One stripe coat and one primer coat of solvent-free, wet & rust tolerant epoxy Epo-chem™ RS 500P was then applied. Areas of deep pitting were then filled with Ceram-chem™ RH 500. To complete the coating system, one topcoat of solvent-free, wet tolerant, glassflake and highly chemical resistant epoxy Epo-chem™ RA 500M was applied.
OUTCOME
The project was successfully completed with no delays or disruption to the surrounding populated areas. Substantial time and cost savings were achieved by utilising this unique and innovative solution only offered by Chemco.
