Bulk Carrier Cargo Liquefaction, TML & Moisture Margin Tool

Screen whether a solid bulk cargo presented for loading remains below its certified Transportable Moisture Limit, how much moisture headroom exists, whether certificates and sampling remain current, and how rain or hold-by-hold variation can consume that margin. The tool deliberately prevents a dry-looking can test or a calculated average from overriding certified TML, representative moisture testing and the Master’s stop-loading authority.

Cargo & IMSBC Basis

Use the cargo’s actual IMSBC schedule and signed shipper documentation. Presets below are descriptive only and do not assign a legal TML.

Hold-by-Hold Moisture Register

Any failed hold / parcel controls the overall acceptance signal. The tool does not average a wet hold into compliance with drier holds.

Rain / Water-Ingress Scenario

This is a sensitivity model only. It estimates how additional water could erode the certified moisture margin; it cannot replace re-sampling and laboratory testing after a material change in moisture condition.

Field Observations & Voyage Indicators

A favorable can test never proves cargo is safe. A suspect result is a stop-and-investigate flag.

Safety limitation: This tool does not authorize loading or carriage. The certified TML, representative moisture-content testing, shipper declaration, competent-authority approvals, applicable IMSBC cargo schedule, Master’s judgment, independent survey advice, flag/port requirements and ship-specific procedures control. A can test is only a field indication and must never be treated as a laboratory pass. Calculated rain sensitivity cannot replace re-sampling and testing after a material change in moisture condition.
Current regulatory basis: The mandatory IMSBC Code currently incorporates Amendment 07-23, which entered into force on 1 January 2025. Amendment 08-25 may be applied voluntarily from 1 January 2026 and is scheduled to become mandatory on 1 January 2027. For cargoes which may liquefy or undergo dynamic separation, the shipper must provide appropriate TML and moisture documentation, sampling/testing must be representative, the moisture content must remain below TML when cargo is on board, the TML test interval must not exceed six months unless characteristics change sooner, and moisture sampling/testing must not be more than seven days before loading. Significant rain, snow or other moisture change requires renewed confirmation.
