The Propulsion Choke: The Marine Engine Duopoly Explainer

The brief: A long-form explainer for What Actually Is on how two companies, Everllence (formerly MAN Energy Solutions) and WinGD, came to design the two-stroke engines that power almost all of the world’s large cargo ships, and what that means for global trade.

What I did:

• Built the research brief: engine licensing, the Dali bridge collision and 2024 Red Sea rerouting as real-world cases, and the methanol versus ammonia race in shipping’s fuel transition
• Fact-checked every claim, correcting common myths in the original brief before scripting
• Directed the script for a Tier-1, analytical audience
• Produced the full video: AI voiceover, 296 custom scene visuals, editing and packaging

The result: A 16-minute deep dive with an average view duration above 5 minutes.
