Sludge builds up in tanks and vessels over time. The sludge needs to be removed at regular intervals in order to maintain a smooth running operation. Sludge removal can be a hazardous task if performed manually. For this reason tank and vessel sludge removal is carried out remotely wherever possible, or with minimum man-entry in confined spaces.

A range of technologies have been developed for the oil and gas industry, as well as the chemical industry and others for sludge removal.
