🌡️ “The Cargo Was Sound at Loading…” — Why Bulk Soya Bean Voyages Turn Into Million-Dollar Claims

 

🌡️ “The Cargo Was Sound at Loading…” — Why Bulk Soya Bean Voyages Turn Into Million-Dollar Claims

Every Master who has carried soya beans knows this tension.

Loading looks normal.
Certificates show compliance.
Moisture within limits.
Cargo temperature reasonable.

The vessel sails.

Thirty-five days later… at discharge…
“Cargo heated.”
“Protein solubility reduced.”
“FFA elevated.”
“Security required.”

And suddenly, a clean voyage becomes a commercial battlefield.

The recent Loss Prevention Insight on the carriage of bulk soya beans reminds us: soya beans are not just bulk cargo — they are living biological material .

Understanding that changes everything.

Let us unpack this practically — from bridge, engine room, and operator perspectives.

 

1️⃣ Soya Beans Are Not Steel — They Breathe, React, and Heat

Soya beans are heterogeneous. A single shipment may contain parcels drawn from multiple farms and silos .

That means:

• Variations in moisture
• Variations in temperature
• Variations in pre-shipment storage

Even if composite certificates show compliance.

The science is simple — and dangerous:

Moist + warm conditions → microbial respiration → heat generation.
Heat → lipid oxidation → more heat.

A positive feedback loop of self-heating develops .

The chart shown in the report (Figure 1, page 3) illustrates how cargo temperature can steadily rise over time during delays .

In extreme cases:

• Caking
• Mould growth
• Heat-damaged beans
• Even charring risk

This is why Brazil–China voyages (30–40+ days) generate high claim volumes .

Long voyage. Tropical climate transitions. Extended exposure.

This is not about one ventilation mistake.

Often, instability begins before loading.

2️⃣ Brazil vs China Standards — The Invisible Dispute Trigger

One of the most misunderstood areas lies in quality standards.

Brazil permits:

• Up to 14% moisture
• Differentiation between fermented and heat-damaged beans

China:

• Moisture capped at 13%
• No distinction — fermented beans may be treated as heat-damaged

Same beans.
Different grading system.

At discharge, claims may arise based on:

• Protein solubility (sound beans >90%)
• FFA (Free Fatty Acid) levels (sound beans <2%)

But here is the commercial twist:

These biochemical parameters are often not tested at load port .

So receivers assess finished products — oil yield, meal digestibility — and claims follow.

As operators, we must recognise:

The vessel is judged not only on cargo condition…
but on downstream processing performance.

That is a very different battlefield.

3️⃣ During Loading — Your Baseline Is Your Shield

The report strongly emphasises pre-loading preparation and documentation .

Before loading:

✔ Clean, dry, odour-free holds
✔ Photographic evidence
✔ Weathertight hatch covers
✔ Ultrasonic testing recommended

During loading:

• Suspend during rain
• Record interruptions
• Collect temperature readings
• Use calibrated probe
• Insert probe and allow stabilisation

If cargo temperature exceeds +10°C above ambient or 35–40°C absolute — issue protest .

This is critical.

Your loading temperature log becomes your reference point.

In disputes, the first question asked is:

“What was the cargo temperature at loading?”

If you do not measure — you cannot defend.

4️⃣ Laden Voyage — Ventilation Is Science, Not Guesswork

Ventilation must follow either:

• Dew point rule
• Three-degree rule (recommended for simplicity)

Three-degree rule:

Ventilate when ambient temperature is at least 3°C lower than cargo temperature.

Consistency matters more than the chosen rule.

Record:

• Ambient temperature every watch
• Ventilation decision
• Justification for no ventilation

Also consider:

• Heat transfer from fuel tanks adjacent to holds
• Keep fuel heating minimal and documented

One overlooked factor: prolonged anchorage before discharge.

The longer cargo remains onboard, the greater deterioration risk .

Masters may consider protest letters in case of excessive waiting.

Good ventilation is not about opening fans blindly.

It is about disciplined decision-making — recorded, calculated, defensible.

5️⃣ Case Studies: Italy vs China — Same Cargo, Different Battles

Italian cases often focus on:

• Elevated temperature
• Shifting costs
• Warehouse storage heating

Even without heat damage pattern, compaction caking can occur after long voyages .

Chinese cases focus more on:

• Heat-damaged beans classification
• Reduced processing yield
• Protein solubility & FFA levels

Critical lesson:

Elevated temperature alone does not prove deterioration .

And after discharge, temperature may continue rising under receivers’ custody .

Evidence matters:

• Multi-depth temperature readings
• Sampling at discharge
• Photographs of damage pattern

This is where calm documentation defeats emotional allegation.

⚓ Final Reflection: Soya Bean Claims Are Won Before the Voyage Begins

Soya bean carriage is not risky because ships are careless.

It is risky because:

• The cargo is biologically active
• Standards differ
• Voyages are long
• Commercial pressure is high

Protection lies in:

✔ Preparation
✔ Monitoring
✔ Consistent documentation
✔ Early Club engagement

As the Insight concludes, awareness and technical understanding are key to protecting Members’ interests .

Shipping is not about eliminating risk.

It is about managing it intelligently.
