ALS determines a safe Transportable Moisture Limit (TML) for bulk cargoes by taking representative samples of cargo and determining the Flow Moisture Point (FMP).
The issuance of FMP/TML certificates is one of the most important tests that ALS can perform , providing confidence to clients that their material is safe to transport via bulk carrier.
The FMP is the point at which a granular bulk material becomes fluid. A Flow Table Test (FTT) is conducted to find the FMP, with the TML calculated to be 90% of this figure. This is the maximum moisture level at which it is safe to ship the material; if the cargo is found to have a higher moisture content than the TML, it is strongly recommended that the cargo not be transported (unless the vessel is specially built for this).
Given the significance of such testing within ALS, all analysts are rigorously monitored to ensure quality standards are met. The decision to load and transport a cargo is ultimately that of the ship’s Master and the port authorities, however highly experienced ALS personnel can assist based on the results of FMP testing performed in-house.
