Greenheart’s Retrofit Playbook, Making Efficiency a Shared Goal

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.
