The TML is defined as 90 per cent of the moisture content at the Flow Moisture Point (FMP) and may be determined using a number of tests including the flow table method described in the 'International Maritime Solid Bulk Cargoes (IMSBC) Code – 2009' and AS 4974.

If the cargo is assessed as having higher actual moisture content than its TML, then IMSBC Code does not allow that the cargo should be loaded and transported by sea unless the vessel is specially built or fitted for confining cargo shift. Bureau Veritas performs the three main IMSBC tests for TML: Flow Table Test. Penetration Test

BULK CARGO LIQUEFACTION - THE CAN TEST Delivery Guide 3 The latest Intercargo Bulk Carrier Casualty Report attributes the loss of 102 seafarers' lives and 11 vessels to liquefaction incidents from 2005 – 2015, with a further incident occurring in 2017 which resulted in the loss of a further
Currently, four methods are used to determine the TML of 'Group A' or liquefiable solid bulk cargoes: i. Flow Table Test, ii. Penetration Test, iii. Proctor/Fagerberg Test, and iv. Modified Proctor/Fagerberg Test for Iron Ore Fines.
Since 2011, mineral cargoes shippers shall comply with a regulatory framework established by the United Nation's International Maritime Organization (IMO): the International Maritime Solid Bulk Cargoes (IMSBC) Code. Some wet mineral cargoes, including some types of iron ore fines, may liquefy during ocean transport, i.e., the …
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 safe ocean transport of bulk commodities like iron ore, coal, nickel ore, manganese ore and bauxite by large bulk ships is vitally dependent on the stability of the cargo under the influence ...
Iron Ore Fines (IOF), which is a bulk mineral cargo, exhibits an inherent high level of risk during marine transportation due to its potential to liquefy. ... Since 2007, there have been at least seven reported bulk carrier incidents possibly caused by the iron ore cargo shifting, as seen in Table 1. Table 1. ... Flow Table Test (FTT) The FTT ...
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
Recent bulk carrier incidents possibly caused by the iron ore cargo shifting [2-7]. ... using the flow table test and the Proctor–Fagerberg test, and the behavior of the shear strength ...
The flow table test, penetration test and Proctor-Fagerberg test, proposed by the IMnI to test an Mn ore fines liquefaction potential, have been shown to give vary variable results for Fe ore fines, as these tests were originally devised to analyse the properties of ore concentrates (Munro and Mohajerani, 2015, 2016b).
The master should check for the possibility of flow in the material being loaded. The can test, set-out in Section 8 of the Code, is described as an 'auxiliary' test method suitable for this. The test is conducted using a can of about 1 litre capacity half-filled with the sample of material to be tested. After noting the appearance

Over the past decade, at least 100 seafarers are known to have lost their lives due to bulk cargoes liquefying at sea. More tragic still is that the deaths could have been prevented if a simple test had been carried out and acted upon before the ships …
1. Introduction. Shipping by sea currently accounts for more than 80% of global trade volume, with iron ore accounting for the largest solid bulk turnover per year, totaling 1.4 billion metric tons by sea in 2016, mainly from Australia (57%) and Brazil (26%) to China (71%) [1].Brazil is the second largest iron ore exporter and has approximately …
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

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.
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 ...
