Based on the flow properties of the iron ore material, modelling of the cargo slip within a bulk cargo is performed as follows. As shown in Fig. 5, for an infinitesimal element located on the potential shear plane within a cargo hold exhibiting a roll angle of θ R, σ 1 and σ 2 are the major and minor principal stresses applied to the …

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 …
at which a sample of cargo will begin to flow. Cargoes with moisture content close to, equal to or in excess of the FMP may liquefy or dynamically separate. The FMP is determined using the flow table test (method 1.1) or penetration test (method 1.2). Loading a cargo above, at or near its FMP represents an

characteristics of the cargo have changed since the last test, even if it is less than six months old, a new TML certificate must be issued (IMSBC code, section 4.5.1) 3.2 Check that the TML is 90% of the flow moisture point (FMP) in the case of the Flow Table Test and the Penetration Test. This 10% safety margin allows for
The flow table test, the penetration test and the Proctor/Fagerberg test. The modified Proctor/Fager-berg test procedure for iron ore fines is an additional method. As each method is suitable for different types of cargo, the selection of the test method should be carefully considered, either in consultation
IRON ORE FINES The provisions of this schedule shall apply to iron ore cargoes containing both: .1 10% or more fine particles less than 1 mm (D 10 ≤ mm); and .2 50% or more particles less than 10 mm (D 50 ≤ mm),. Notwithstanding the above provision, iron ore fines where the total geothite content is 35%
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 ...

Each method is applicable to specific …
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
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.
Facts Origin Russia, Brazil, China, Australia, India and the U.S.A. Stowage factor (in m 3 /t) : Varying largely; several iron ore products are classified as heavy bulk cargo, which means that due to their dense structure overstressing of tank tops or ship's structures can occur in case improperly loaded and or distributed over a ships hold.
