Initial Client Problem

Our client, a hydroelectric power plant company in Serang, had two fuel tanks with a capacity of 2,000 kL each. The tanks were filled with HSD Fuel and needed replacement with Biodiesel B30. The procedure for changing from HSD to B30 fuel required tank cleaning. We successfully completed the tank cleaning job on the first tank with results that met the target, finished on time, and were of satisfactory quality of work. In this job, we also performed the tank cleaning job on the second tank with the same challenges as for the first tank.

Our Solution

As with the first tank job, we successfully completed the second tank job before the due date while adhering to safety regulations for working in confined and closed spaces. We inspected for the presence of hazardous gases, particularly H2S, CO, and other gases. Additionally, we conducted the gas removal process for the tank. Furthermore, we purified the HSD fuel, which had been contaminated by sludge and water, using our fuel polishing unit equipment. Subsequently, we cleaned the tank using a water jet, a liquid alkaline solution, and manual cleaning. The clean condition of the tank allowed our client to perform an annual tank inspection.
