Abstract

A fluid storage tank (2) comprising a chamber (4) having a roof (6) arranged to float upon a body of fluid contained in the chamber (4). A nozzle is (8) is suspended from the roof (6) and pumping means (18) are arranged to circulate a flow of oil through the chamber (4) via the nozzle (8), to inhibit or disperse a build-up of solid or semi-solid materials upon the floor of the chamber (4). <IMAGE>
