The Client: Ship management company.
The Project: Investigation into the blistering of the cargo tank coatings on a fleet of chemical tankers to determine the cause of the blistering.
Our Role: Safinah’s role was to survey the cargo tank coatings and take appropriate paint flake samples for analysis by computerised optical microscopy. Based on the inspection, the vessel cargo history and the paint flake analysis, Safinah was able to determine the cause of the blistering was due to poor surface cleaning prior to application of the tank coatings.

Blasting grit and corrosion contamination on the underside of paint flakes taken in way off blistering
Tank coating in good condition and blister free.
Underside of paint flakes from blister free tank are clean and free of blasting grit contamination
How Safinah Added Value: The report has allowed the client to understand the extent of defects in the tank coatings to allow for:
- An accurate estimation of repair specifications.
- Anticipate future issues with the tank coatings on other vessels in the fleet.
- Engage in dialogue with the coatings supplier
