❄️ When the Sea Freezes: What Masters Must Remember Before Calling Northern China Ports

 

❄️ When the Sea Freezes: What Masters Must Remember Before Calling Northern China Ports

Winter at sea is not just cold.
It is deceptive.

The bridge looks calm. The sea appears steady.
But beneath that grey horizon… ice is forming.

For vessels trading to Northern China in February, ice is not theory — it is operational reality.

According to Oasis Circular No. 2602 dated 9 Feb 2026 , floating ice in the Yellow Sea and Bohai regions is expected to develop further this week.

If you are bound for Yingkou, Huludao, Dandong — this matters.

Let us break this down practically — from a Master’s and operator’s perspective.

 

1️⃣ Ice Forecast Is Not Just Information — It Is Operational Risk

The circular highlights:

• Liaodong Bay: 40–50 sq. nautical miles of floating ice
• Northern Yellow Sea: 5–15 sq. nautical miles
• General ice thickness: 5–15 cm
• Maximum thickness: Up to 20 cm

These numbers are not statistics.

They translate into:

• Increased hull abrasion risk
• Anchor chain icing
• Reduced maneuverability
• Potential delays
• Insurance exposure

⚓ A 15–20 cm ice sheet may not stop a vessel — but it will test seamanship.

This is where leadership on the bridge matters more than horsepower.

2️⃣ Drain the Deck Lines — Small Action, Big Consequences

One of the most practical reminders in the circular:

Drain deck piping systems before arrival to avoid cracking due to freezing

This sounds simple.

But how many claims have started from a frozen line?

• Cracked fire main
• Damaged deck wash lines
• Leaking ballast lines
• Port State issues
• Class remarks

In freezing conditions, water trapped inside pipelines expands.

Steel does not forgive.

A five-minute preventive action can prevent:

• Expensive repairs
• Operational delay
• Off-hire exposure

This is not about paperwork compliance.
This is about operational maturity.

Real seamanship is often invisible.

3️⃣ Speed, Lookout & Hull Awareness — Ice Is Not Open Sea

The circular advises:

• Maintain safe speed
• Keep proper lookout
• Minimize scratches or hull damage

In ice conditions:

Full sea speed is not bravery.
It is exposure.

Even light floating ice can:

• Damage coating
• Scratch hull plating
• Affect fuel efficiency
• Increase resistance

And if hull condition deteriorates — next dry dock costs increase.

This is where Masters must balance:

📊 Commercial pressure
⚓ Safety judgement
🧭 Long-term vessel condition

Young officers watching the bridge learn from these decisions.

Leadership in winter waters shapes the next generation.

4️⃣ Anchoring in Ice — The Silent Risk

Anchoring in icy waters brings hidden threats:

• Anchor dragging
• Ice buildup on chain
• Loss of holding power
• Mechanical stress

The circular reminds vessels to:

• Monitor anchor position
• Regularly check anchor chain ice condition

In sub-zero conditions:

Ice accumulation increases chain weight and stiffness.
Wind + current + ice = unpredictable load.

This is where:

🔍 Vigilance
⏱ Frequent checks
⚙ Deck readiness

make the difference between a controlled anchorage and a drifting casualty.

Remember — winter does not give second chances.

5️⃣ What This Means for Operators & Chartering Teams

This circular is not only for the bridge.

Operators and chartering teams must consider:

• Possible delay due to ice
• Reduced speed
• Increased bunker consumption
• Risk of hull damage claims
• Insurance notification requirements

Winter navigation affects:

📊 Laycan planning
⏳ NOR timing
📑 Claim exposure
💰 Off-hire disputes

Proactive communication between:

Master ↔ Operator ↔ Charterer

prevents conflict later.

Shipping is not about reacting to problems.
It is about anticipating them.

⚓ Final Thought

Winter does not test ships.
It tests judgement.

A well-prepared vessel is not lucky.
It is led properly.

If your vessel is heading toward Northern China this week —
Pause. Review. Prepare.

Small precautions today prevent large claims tomorrow.
