In April 2014, Chemco International’s protective coatings were used to eradicate the corrosion problem found inside four cargo tanks. The tank tops found inside these four tanks (3 Port, 4 Port, 4 Stbd & 6 Port) required a full refurbishment as they were showing signs of severe corrosion damage.
All the tank tops and up to 0.5m high on the surrounding bulkheads were grit blasted to SA 2.5 standard. Prior to the coating application, the surfaces were swept and vacuumed to remove any dust and other contamination which may have been on the surfaces of the grit blasted areas.
Following the surface preparation, two coats of high chemical and high temperature resistant, glassflake reinforced Chem-tect™ RB 364 were applied @ 500µ DFT per coat by airless spray.
When the second coat was dry, one stripe coat of Chem-tect™ RB 364 was applied by brush. The coating application was completed by applying one topcoat of Chem-tect™ RB 300TC @ 100µ DFT by airless spray.
The work was carried out within the given time-frame for completion of the project, with no delays and was supervised by Chemco’s technical staff. All the cargo tanks were completed to class standard and certified accordingly to the satisfaction of all concerned.
Implementing this protective coating system gives our clients the following benefits:
- Excellent resistance to highly aggressive chemicals at high temperatures
- Fast curing system allowing for quicker over-coating
- Reduced H&S and Fire Precaution (Chem-tect™ RB 300 is 100% volumes solid)
- Reduced downtime leading to substantial cost savings
