Conventional and Non Man-Entry Tank Desludging and Cleaning

Many hydrocarbons, and in particular Crude Oils, deposit significant volumes of sludge. Crude Oil is a complex blend of hydrocarbons of various molecular weights from methane gas to high molecular weight aliphatic and aromatic compounds.

It is from these high molecular weight hydrocarbons that sludge is formed, combining on the floor of the tank with sand, silt, scale and water to form a semi-solid material.

SLUDGE can be defined as any material in a storage tank which will not flow under gravity to a suction point.

API 653, and other codes, require that storage tanks are internally inspected regularly for internal corrosion.

Confined space entry is an extremely hazardous activity that needs to be carefully controlled to ensure that risks to personnel are limited. It is generally accepted that the application of any system which reduces man-entry is highly desirable. Steve Scott has more than 30 years experience in the design and application of non man-entry tank desludging and cleaning systems.
