We undertake tank cleaning of petroleum tanks and this consists of tank isolation, product transfer, de-slugging, gas freeing, cleaning and grit blasting which are in compliant with the SANS 10089-1 and API 653 standards. These services form part of the pre-maintenance requirement for any tank maintenance and repair work. Before tank cleaning is performed relevant permits need to be obtained (i.e. Work permit and Confined space entry permit among others). Figure 1 show tank cleaning.
