Ballast Tank

OVERVIEW:    Due to the high cost associated with environment control and grit removal, abrasive blasting could not be carried out. Chemco’s range of surface/moisture tolerant coatings which are solvent free were applied following mechanical cleaning and high pressure water blasting of the surface.

ENVIRONMENT

Sea mist & sludge

SUBSTRATE

Mild Steel

CHALLENGE

Due to the high cost associated with environment control and grit removal, abrasive blasting could not be carried out

SOLUTION

Mechanical clean and high pressure water blast the surfaces to be treated. Chemco’s range of surface/moisture tolerant coatings which are solvent free will provide a minimum 10 years corrosion protection. 

SCOPE

Assess floor area after sludge removal

Mechanical clean  (some areas difficult to reach)

High pressure water blast up to 19,000 PSI

Stripe coat all welds and sharp corners using RS 500P

Apply 1 coat of RS 500P to a DFT of 100µm

Install Fibreglass patches over holes and apply 1 coat of RA 532

DFT checks to ensure require thickness is reached

OUTCOME

The client was extremely pleased with the results, particularly due to the degree of difficulty. Oil Platform passed all DNV requirements
