Non Man Cleaning


Non-Man Entry Tank Cleaning

Allerion Oilfield Services now offers a Non-Man Entry Tank Cleaning solution. This next level and fully automated technology is amazingly safe and can reduce overall tank outage time considerably, when compared to conventional cleaning methods.


This Automated Cleaning technique is a combination of patented Single Nozzle Sweepers (SNS) and an integrated turnkey mobile separation technique. The mobile and self-powered process generates low pressure, high impact jets of recirculated tank fluid which efficiently cleans all internal surfaces of the tank in a precise computer-controlled pattern. The oil and water recovered from the tank are separated of solids and reused for cleaning. This effectively reduces the cleaning time and lowers the water usage. This system is self-sustained with both air and power for the cleaning process, thus eliminating the need for the tank owner to supply these utilities.
