⚓ When Every Knot Counts: What Shipping Must Understand About Whales

Introduction – The Responsibility We Don’t Always See

There are moments at sea when everything feels mechanical — ETA pressure, charterer calls, fuel figures, port congestion. The bridge is quiet, the radar steady, the schedule tight.

And somewhere ahead — unseen beneath the surface — a whale is crossing your track.

Shipping is built on precision, but not everything on the ocean shows up clearly on radar.

As vessel traffic grows and migration routes overlap busy shipping lanes, the responsibility on our industry grows too .

This is not just about compliance.
It is about seamanship.

Let’s pause and reflect on what this really means for us as maritime professionals.

 

🚢 1️⃣ Every Knot Counts – Speed Is Not Just a Commercial Decision

On paper, speed is about fuel efficiency and schedule integrity.

In reality, speed can be the difference between avoidance and impact.

Research referenced in the article shows that vessels travelling at 15 knots or more significantly increase strike probability, while reducing speed to 10–12 knots can cut risk by 30–40% .

Now imagine this:

You are on night watch approaching a coastal port. Traffic separation scheme ahead. Engines at full sea speed. Visibility fair. No reported hazards.

And yet, a whale surfacing late gives you seconds — not minutes.

At high speed, even good seamanship may not be enough.

Slower speeds give:

• More reaction time for the bridge team
• Better manoeuvring window
• Greater avoidance chance for the whale

Seamanship is not just collision avoidance between steel hulls.

It is about respecting the living ocean beneath us.

🌊 2️⃣ The Noise We Don’t Hear – Underwater Radiated Noise (URN)

Most of us think of collisions when we discuss whale protection.

But another impact is invisible: underwater radiated noise.

Propeller cavitation, hull vibration, machinery noise — these low-frequency sounds travel long distances underwater .

To us, the engine sounds normal.

To whales, it can:

• Disrupt communication
• Interfere with feeding
• Cause stress or disorientation

The IMO has issued updated guidelines (MEPC.1/Circ.906/Rev.1) to reduce underwater noise .

Here’s the powerful insight:

Many whale-protection measures align with good ship management.

• Smooth propellers
• Clean hulls
• Well-maintained machinery
• Optimised routing
• Reduced unnecessary anchor time

Good technical management is environmental stewardship.

The Chief Engineer’s maintenance routine is not just about performance — it quietly protects marine life.

That is leadership beyond compliance.

🧭 3️⃣ Voyage Planning Beyond Charts – Knowing Where the Whales Are

Voyage planning today includes weather routing, piracy zones, ECA compliance, draft restrictions.

But how many bridge teams actively check whale migration data?

The article highlights tools like:

• WWF’s Blue Corridors map
• World Shipping Council’s Whale Chart
• Whale Atlas digital tools

These are not theoretical resources.

They are practical voyage planning aids.

Before departure:

• Check known whale-sensitive zones
• Verify active speed restriction areas
• Review coastal notices to mariners
• Monitor temporary restrictions

A Master who plans with awareness protects:

• Crew
• Company reputation
• Insurance exposure
• Marine ecosystems

This is proactive command — not reactive response.

Good navigation anticipates what cannot be seen.

⚓ 4️⃣ Training and Culture – Protection Is a Leadership Choice

Procedures exist.

Guidelines exist.

But culture determines action.

The article recommends:

• Crew training on whale identification
• Verifying speed restriction zones
• Posting dedicated lookouts
• Reporting whale sightings and strikes

Let’s be honest.

Under commercial pressure, reducing speed voluntarily takes courage.

Encouraging lookout vigilance takes discipline.

Reporting incidents transparently takes integrity.

Environmental responsibility at sea is not about slogans.

It is about daily operational decisions.

When Masters explain why speed reductions matter, crews comply with understanding — not fear.

That is how culture is built onboard.

Quietly. Consistently.

🌍 Final Reflection – The Ocean Is Our Workplace

Shipping keeps the world moving.

But the ocean is not only a trade route.

It is a living system.

Every knot, every routing decision, every maintenance task carries invisible consequences.

Professional seamanship today includes environmental awareness.

Not because regulators say so.

But because responsible mariners understand the privilege of operating at sea.
