CRUDE OIL TANK WASHER DEVELOPED BY NIIKURA KOGYO JOINTLY WITH JSHDA

The article describes a hydraulic crude-oil tank auto-cleaner, the Hy-Otac Mark II. The crude-oil washing system involves using part of the cargo oil for cleaning the cargo tanks of tankers while they are being unloaded. Crude oil is much more effective than sea water because some of its ingredients act as solvents dissolving the oily residues which cannot otherwise be discharged. The Hy-Otac is simple in design, requires little maintenance, and possesses a variable nozzle-turning speed. Unlike other methods, crude-oil washing is first applied to the upper part of the tank when the cargo level has dropped and then to the lower part when the tank is empty. This two-phase procedure results in substantial time saving. Order from: BSRA as No. 47,832.
