When should you begin to pump out slops during the Butterworth tank cleaning process?

During the Butterworth tank cleaning process, it is essential to begin to pump out slops when the cleaning process is started. This timing is crucial because it allows for the immediate removal of contaminated liquid and sludge that is being displaced during the tank cleaning operation. The slops are generated as the cleaning system uses high-pressure water jets to wash the interior surfaces of the tank, breaking down and loosening residues that have accumulated over time.

Starting the pumping of slops in conjunction with the cleaning process ensures that any contaminants are swiftly removed from the tank's environment, minimizing the potential for the debris to settle again or cause blockages in the system. This practice also helps to ensure proper safety measures are followed, as it reduces the risk of hazardous conditions resulting from accumulated slops within the tank.

Waiting until after cleaning is completed or moving the pumping to halfway through the process could result in an overloaded system, increasing the risk of contamination or disruption. Therefore, initiating the slop removal at the start aligns with best practices in cleaning and safety protocols in tanker operations.
