07/04/2017  Nickel ore is a cargo that may liquefy if the Moisture Content (MC) exceeds the Transportable Moisture Limit (TML). The point at which the cargo can begin to act like a liquid is when the Flow Moisture Point (FMP) is reached: a theoretical figure set at 90% of the FMP to create a 10% safety margin. Since 2011, the American Club have issued several Circulars and Alerts concerning
