Automated tank cleaning (ATC) technology is used to clean oil sludge inside the tanks instead of a traditional manual method. ATC is an advanced technology which can recover the oil with a capacity of 95 percent from the hydrocarbons sludge with zero-hazardouss material disposal. The ATC solution is considered by far the most effective solution when it derives to safety, economy and environmental aspect of the industries standards. In term of safety, ATC requires “no man entry” to the tank, which in return reduces the high risk involved in having personnel enter confined spaces. Economically, ATC requires little time to clean a tank compared to manual cleaning. Oil recovery is considered as an environmental protection.
