Abstract

The invention concerns a method for cleaning an oil storage tank (1) with a floating cover containing crude oil, which consists in partially emptying the tank (1) above the sludge (3) contained therein; sucking up the crude oil and re-injecting it into the tank (1) using diffuser spray nozzles (5) borne by the floating cover (2), each spray nozzle being driven in rotation by a motor. The injection with the spray nozzles causes the oil volume to swirl and the sludge (3) to be suspended again in the oil. The invention also concerns a device for implementing said method.
