Abstract

An apparatus for removing oily sludge from an installation bottom includes at least one gas sparge pipe, a collector in the form of a sloping inverted channel positioned above the sparge pipe so that sludge lifted by gas from the sparge pipe rises up into the collector, a riser pipe connected to the collector, and a gutter to which entrained sludge is fed by the collector via the riser pipe.
