ABSTRACT:
A method and apparatus for converting crude oil tank bottoms in the cargo tanks of a ship to a liquid state is provided. The method comprises subjecting crude oil sludge contained in the tanker cargo tank to a collection system to facilitate extracting the sludge mixture from the bottom of the tank; comminuting the sludge mixture to reduce the size of sludge globules contained therein to produce a homogeneous mixture; optionally adding crude oil from the cargo tank to increase the homogeneity of the mixture; optionally adding an additional quantity of cutter stock and/or other selected additives to the sludge mixture, either before, during or after comminution, to form a blend stock.
