Abstract

MTD Australia Pty Ltd ABSTRACT Title: The application of an additive that absorbs moisture and reduces the liquefaction potential of a granular bulk solid material during transport. Abstract: This patent applies to the use of an additive that absorbs moisture with the potential to reduce the liquefaction potential of a granular bulk solid cargo. Liquefaction can affect the stability of a vessel/ship for which currently there are no remedies and/or control interventions available. The patent defines a new use for a superabsorbent polymer and the method of application/distribution of the material within a laboratory test sample and additionally the method of application/distribution during loading and/or in a cargo hold onboard a Vessel/ship to reduce the liquefaction potential of the cargo. The additive is pneumatically introduced to the material. The additive then reacts with the moisture, thus removing the moisture from a potential liquefaction process. The quantity of additive applied and reaction time are dependent on the material qualities/properties and pressure of pneumatic introduction.

DESCRIPTION
Title: The application of an additive that absorbs moisture and reduces the liquefaction potential of a granular bulk solid material during transport.
Description: Granular Bulk cargoes such as metal ores, coal, bauxite etc. when carried in bulk, for example in a ships cargo hold on a sea passage, can have the potential to liquefy and have a negative effect on the ships stability.
Addition of a super-absorbent polymer additive has been found to reduce the liquefaction potential of those cargoes suspected or considered to be vulnerable to liquefaction.
This patent applies to the use of and application method for a super absorbent polymer whereby it is pneumatically introduced into a sample during use for laboratory testing and in bulk to a vessels cargo hold during cargo movement. Additionally, a secondary pneumatic application of the addition of the additive to a bulk cargo in a Vessel's cargo holds is when the cargo is identified as presenting a real possibility of liquefying.

    CLAIM
    Title: The application of an additive that absorbs moisture and reduces the liquefaction potential of a granular bulk solid material during transport.
    Claim: Patent protection is required to preserve the uniqueness of the application and use of a moisture superabsorbent polymer along with its pneumatic method of application to a bulk granulated cargo in order to reduce/minimize the cargoes potential to liquefy particularly when carried at sea in a Vessels' cargo hold/tank.
