In this episode, Steen Sander Jacobsen, Technical Director at Njord, joins us to unpack what MEPC 83 means for the industry, and why waiting for regulation could mean missing the opportunity that’s right in front of us.

While the IMO’s Net Zero framework discussions have been extended into next year, Steen shares a reminder: “Regulation will evolve, but efficiency already makes business sense today.”

In this conversation, we cover:

1. The significance of MEPC 83’s delayed outcome for shipowners

2. What actions can be taken under existing frameworks like EU ETS or FuelEU Maritime

3. The growing collaboration between shipowners, charterers, financiers, and ports

4. Why planning your next drydocking cycle could define your decarbonization journey

The path to net zero may not yet be fully mapped, but every voyage starts with a first move.

In this episode of Seathrough Efficiency, we speak with Nikos Benetis from Greenheart, part of the Hayfin group, about how retrofit strategies go beyond compliance — and start with values.

Key themes from the conversation:

• Efficiency is a mindset: Greenheart’s team is driven by doing the right thing, not just ticking regulatory boxes.
• Retrofit starts with transparency: Sharing performance data and lessons learned is central to their approach.
• Due diligence with purpose: Vessel performance is as critical as financial modeling when evaluating fleet investments.
• Learning loops matter: Retrofit success comes from observing, evaluating, and evolving — not just installing tech.
• Partnerships are key: Shipowners, suppliers, and consultants all play a role in shaping smarter vessels.

Greenheart shows how environmental action can be embedded in every decision — from second-hand vessel upgrades to newbuild ESG planning.

In our latest podcast episode, we spoke with Patricia Ayoub from DOF about their decarbonisation strategy and the lessons learned from bringing two fleets together.

Patricia outlined three clear pillars guiding DOF’s approach:

1. Operational efficiency – optimising how vessels are run day to day

2. Technology upgrades – deploying smart tools and hybrid solutions

3. Fleet renewal – investing in next-generation vessels

Key points stood out:

1. Small, incremental changes add up to significant impact over time

2. Transparency on vessel performance builds trust across stakeholders

3. Managing efficiency at scale after a major fleet merger requires discipline and collaboration

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
