Coal Cargo Shipments: Why TML, Moisture, FMP & Free-Draining Declarations Matter

 Coal Cargo Shipments: Why TML, Moisture, FMP & Free-Draining Declarations Matter ⚓🚢

❓ Three Quick Questions for You

1. Do you always double-check the shipper’s cargo declaration before loading coal?
2. Are you aware of how TML, Moisture Content, FMP, and Free-Draining figures can impact vessel safety and liability?
3. Could a small oversight in these numbers put your crew, cargo, and company at legal and financial risk?

If your answer is not a confident YES to all three — this blog is for you.

 

🔎 Clause Breakdown: Shipper’s Declaration for Coal Cargo

When loading coal cargoes, the shipper must provide a declaration with:

• TML (Transportable Moisture Limit): Maximum moisture content a cargo can safely carry without risk of liquefaction.
• Moisture Content (MC): Actual measured water content in the cargo.
• FMP (Flow Moisture Point): The point at which cargo starts behaving like a liquid.
• Free-Draining Condition: Confirmation that excess water drains out freely, ensuring cargo stability.

🚨 Why It Matters

• Liquefaction risk: If MC > TML → the cargo can shift dangerously, risking vessel stability and capsizing.
• SOLAS Regulation: Requires accurate shipper declarations. Incorrect figures = breach of international law.
• Owner/Operator liability: If loading proceeds without proper checks → owners may face claims, detentions, or P&I exclusions.

⚖️ Examples & Case Law

• Bulk Jupiter (2015) tragedy in the South China Sea highlighted the dangers of inaccurate cargo moisture declarations.
• BIMCO clauses and P&I circulars emphasize the master’s right to reject cargo until reliable test results are provided.

⚠️ Common Pitfalls

1. Accepting shipper’s declaration at face value without independent testing.
2. Confusing FMP with TML — leading to wrong assumptions.
3. Not verifying “free-draining” condition, especially after rainfall at stockpiles.

 

🛠️ Actionable Steps for Ship Operators / Managers / Owners / Charterers

1. Always demand full declaration: TML, MC, FMP, and Free-Draining status before loading.
2. Independent sampling/testing: If in doubt, request independent laboratory verification.
3. Weather monitoring: Avoid loading coal during heavy rains; insist on fresh sampling.
4. Master’s authority: Empower the Master to stop loading until cargo safety is proven.
5. Contract clarity: Insert BIMCO standard clauses into C/Ps to protect owners’ rights.
6. Crew training: Ensure officers understand how to interpret and act on cargo declarations.

 

✅ Conclusion & Call-to-Action

In shipping, numbers save lives.
The difference between safe loading and disaster often lies in one decimal point on a cargo declaration.
