In this episode of Seathrough Efficiency, Saurabh breaks down what we learned from installing Wind Assisted Propulsion - not theorising about it.

We will cover our FIVE biggest learnings, so if you're considering wind for your fleet, this one is worth a listen. It's honest, specific, and focused on what matters when you move from plan to practice.

In this episode of Seathrough Efficiency, we speak with Martin Wattum, Head of Energy Efficiency Projects at Klaveness Combination Carriers, about turning energy efficiency from a strategic priority into operational reality.

Topics include:

-         How to assess and prioritize technologies

-         How to handle risks around energy efficiency investments

-         Why crew engagement often defines the success of retrofits

It’s a practical look at how Klaveness is aligning daily operations with long-term sustainability strategy.

In this episode we go back to where it all began, the Maersk Ingrid retrofit. We are joined by Steen Sander Jacobsen, Technical Director at Njord, to explore the very first retrofit project and the lessons it taught us about energy efficiency at sea.

From unexpected performance results to breakthrough insights, Steen shares what made Maersk Ingrid a unique candidate, how technologies were tested and measured, and what this case still teaches us today.

Topics covered:

• Why Maersk Ingrid was chosen for deep retrofit
• Measuring real-world performance across systems
• Surprising results from PBCF, Mewis duct, and VFDs
• The biggest learning from the project
• How this case shaped future retrofit strategies

We sat down with Frederik, Managing Director at Njord, to talk about what boards really want to hear when you pitch a retrofit.

In this episode:

1. Why ROI alone isn't enough

2. How to handle risk and uncertainty

3. Getting alignment across technical and commercial teams

4. What happens after the board says yes
