在马来西亚装运黏土需谨慎

在过去十年时间里,已经发生了多起装于马来西亚的散装黏土在航行中在船舶货舱内发生液化的事件。

近期某船沉没的事件提醒业内注意,黏土货物相关风险依然存在。

在已知案件中,货物在马拉西亚 Lumut 被装载上船。据了解,托运人将货物申报为“ball clay (并非 IMSBC Code 中被认可的散货运输名称),或者干脆申报为“clay”。

IMSBC Code 规则将 CLAY 列为 C 类货,这表明 CLAY 货物在散装运输时不易发生液化。

然而,由在 Lumut 装载货物的经验可知,黏土货物具有流动水分点(因此具有适运水分极限(TML)),表明如果其含水量超过 TML,此种货物就容易液化。

在马来西亚装运黏土货物时,即使货物被申报为 C 类货,仍需格外小心,并注意液化风险。


The last decade has seen several reported instances where bulk clay cargoes loaded in Malaysia liquefied in the holds of the carrying vessel during the voyage.


The recent loss of the a ship serves as a reminder that the risks associated with clay cargoes remain.


In the known incidents, the cargoes were loaded at Lumut, Malaysia. They were declared by the shipper as either ‘ball clay’ (which is not a recognised bulk cargo shipping name in the IMSBC Code) or simply ‘clay’.


The IMSBC Code lists CLAY as a Group C cargo, which suggests that it is not liable to liquefy when carried in bulk.


However, experience of clay cargoes loaded at Lumut suggest they possess a flow moisture point (and therefore a transportable moisture limit (TML)), indicating that they are liable to liquefy if its moisture content exceeds the TML. 


When loading clay cargoes in Malaysia, exercise great caution and be aware of the risk of liquefaction, even if it has been declared as a Group C cargo.
