For cargoes prone to liquefaction, exceeding the TML can lead to sudden loss of shear strength under ship motion, causing cargo shift and endangering vessel stability. The TML Testing Apparatus provide a reliable, repeatable solution for ports, shipping companies, inspection agencies, and mining laboratories to prevent such risks at source.
The TML-D Portuguese-Fagerberg TML Testing Apparatus is a professional and precision testing device independently developed by Qingdao Decent Group for liquefiable solid bulk cargoes, fully compliant with the International Maritime Solid Bulk Cargoes Code (IMSBC Code) and designed based on the classic Portuguese-Fagerberg testing method.
Adopting dynamic compaction simulation technology, the device accurately restores the actual compaction state of cargo at the bottom of the cargo hold caused by ship movement and vibration during navigation. By correlating three core indicators of the sample: void ratio, dry density and saturation, it scientifically determines the maximum total moisture percentage of the cargo without the risk of liquefaction and dynamic separation, namely the Transportable Moisture Limit (TML). It builds a solid technical safety barrier for the maritime transportation of iron ore, coal, bauxite and other bulk cargoes.
Qingdao Decent Group is a professional manufacturer of TML Testing Apparatus, focusing on the R&D and manufacturing of bulk cargo testing equipment.
The TML-D Portuguese-Fagerberg TML Testing Apparatus is an integrated standard compaction testing system, mainly composed of exclusive testing components, intelligent control unit, basic support system and auxiliary parts.
