Bottom of Tank #67 of leading oil company in Malaysia Project: Tank Bottom Of Tank No. 67 Location: Miri Crude Oil Terminal (MCOT), Miri, Sarawak, Malaysia. Applicator: Eastern Energy Services Sdn Bhd Date Of Application: June 2000 The Challenge: The crude oil tank has been in service for over a decade and entire area is heavily corroded. The client wants to do a good rehabilitation job that will fit their budget and at the same time attain long-term protection for this structure. There is no more trace of the existing tank coating and deep pits due to corrosion are scattered on the entire area. Requirement: Abrasive blasting and filling up all deep pits by welding or replacing the deteriorated steel plates was the recommendation of their in-house maintenance. If said steel plates passed the thickness gauging, then the pitting can be filled up by Corro-Dur 561 instead of welding which is much cheaper, faster and will perform well. Corro-Dur 258 was used to coat the entire bottom of the tank at 400 to 600 microns dry film thickness. The Corro-Dur products were primarily selected for this job since it is 100% solids, environment and user friendly. It can withstand different petroleum products and other chemicals. It can be applied on wet, damp or wet surfaces and good adhesion can be obtained even if the surface preparation is power tool or high pressure washing, but to attain maximum performance, abrasive blasting is recommended.
