If the flow table test is not suitable for the material in question, the procedures to be adopted should be those approved by the authority of the port State. The test provides for determination of: the moisture content; the flow moisture point (FMP); and the transportable moisture limit of the test material. Describe the flow table test.

Cargo liquefaction is a well-known hazard for shipping solid bulk cargoes. Cargoes which are considered susceptible to liquefaction are typically characterized as fine grained, non-cohesive ...
The Flow Moisture Point is the percentage moisture content at which a flow state develops under the prescribed method of test in a representative sample of the material. Iron Ore concentrate loading operation with continuous checks of moisture by ship and terminal. Liquefaction is the transformation of solid material into a nearly fluid state.
In 2013, over 500 million metric tons of Iron Ore Fines (IOF) were transported around the world using bulk carriers. Under certain conditions IOF, while being transported, can possibly undergo liquefaction. Since 2006, there has been eight reported bulk carrier casualties possibly caused by the liquefaction of IOF.

What are we testing these samples for? Is calculated as a percentage of the total mass weight based on the dry weight of soil. Is the inherent moisture content (%) in a material at which a …
Iron ore fines The IMSBC Code definition for iron ore refers to cargo in the size range of up to 250mm, and iron ore fines 10% or more of fine particles of less than 1mm and 50% or more of particles less than 10mm. Moisture contents quoted for iron ore fines typically vary between 6 to 12%, with iron ore having lower moisture content.
Bulk density can be measured by a single test, using the Proctor C apparatus described in ASTM Standard D-698 or JIS-A-1210, on a sample of the cargo at the proposed moisture content of …
Iron Ore Fines (IOF) are a product of iron ore, commonly having a particle size less than 6.3 mm, which is transported around the world in bulk carriers. Since the holds of bulk carriers are not designed to carry liquid, if liquefaction of IOF or other minerals occurs, it can cause the vessel carrying the cargo to list or even capsize.

The TML of cargo is the maximum gross water content by weight that liquefiable solid bulk cargo may contain during transport without risk of liquefaction. The liquefaction phenomenon can see materials, most commonly iron ore fines, nickel ore, and various mineral concentrates, transform from a solid dry state to following the laws of fluid ...
Iron ore and iron ore fines are two separate cargoes. Iron ore largely comprises lumpy material resembling small rocks or stones of 10-25 mm in diameter. It is defined as a category 'C' cargo under the IMSBC Code, meaning it is not liable to liquefy. Iron ore fines are largely made up of powdery material below
In 2013, over 500 million tonnes of Iron Ore Fines (IOF) were transported around the world using bulk carriers, more than any other unrefined mineral. Since the holds of bulk carriers have not been designed to carry liquid, if liquefaction of IOF or other minerals occur it can cause the vessel carrying the cargo to list or even capsize.

If some solid bulk cargoes such as concentrates, unprocessed nickel ores and iron ore fines contain sufficient moisture, then cargo compaction during a voyage may cause liquefaction. This has been known to result in major cargo displacement ('cargo shift'), causing the vessel to capsize. This has resulted in a number of fatalities. To provide context to this interdisciplinary …
