SLB used its ATC™ automatic tank-cleaning technology with a mixture of water and a specific 1% chemical solution pumped into the tank cleaning machines (TCMs). For slop reclamation, the system deployed diaphragm pumps to reclaim all slop volumes, enabling the cleaning fluid to be recycled on a constant basis and reducing cleaning time, slop volume, and worker exposure. There was a 50% reduction in waste and an 86% reduction in confined-space entry, which significantly reduced HSE risks during the process.
