What we talked about
Dominique Roddier is a naval architect, ocean adventurer, and CEO of Ocergy, a company developing sustainable offshore solutions for clean energy. In this episode, recorded dockside in a Northern California marina on a strangely warm November day, Dominique and Federico use the ocean as a lens to explore global warming, human humility, and the future of renewable energy.
Show notes
Dominique Roddier sat outside in a shirt in late November in Northern California and opened the conversation by pointing out that the warm weather itself was evidence of what they were about to discuss. He wanted to be a tanker captain at age seven, because it was the biggest ship he knew of, and ended up becoming one of the leading voices in floating offshore wind technology instead.
What we covered
- Naval architecture has two core disciplines: hydrodynamics (understanding how ocean forces act on a floating structure) and structural engineering (designing something that won’t sink, collapse, or break under those forces). To illustrate the scale, Dominique once Photoshopped the Transamerica Tower sideways under the Golden Gate Bridge in a presentation to architects, every offshore structure must be entirely self-sufficient for power, communication, and survival, unlike a building connected to the grid.
- The most visible signs of ocean warming are not coastal flooding but disrupted regulation: the Gulf Stream keeps northern Europe warm, and the Pacific keeps San Francisco cool. When ocean temperatures rise, more energy feeds into weather systems, Dominique points to the largest hurricane ever recorded hitting the Caribbean months before this recording, killing hundreds of people, as a direct consequence. He says the 1.5-degree warming target “should be negative, not positive, we’re too hot already.”
- 80% of the world’s usable offshore wind sites are in water deeper than 60 meters, which makes bottom-fixed turbines impossible or prohibitively expensive. Two kilometers off the California coast, the water is already 700 meters deep. Floating platforms are the only way to access this resource, and Ocergy has been working on the technology since 2007.
- The floating wind industry’s cost problem is not solved by removing components but by reducing every element across the full supply chain by 10-15%. Dominique draws directly from the Toyota Production System, specifically just-in-time delivery and Jidoka, as the model for industrialization. He argues that building a dedicated concrete factory for floating wind projects is the wrong approach: it frontloads costs that the first two projects must pay back, making the economics impossible.
- Ocergy’s design is bolted together with flanges rather than welded as a single unit, which means the structure can be shipped disassembled. Instead of transporting one complete platform per vessel, they can pack five, six, or seven sets of components onto the same ship, changing the logistics math dramatically and enabling local fabrication yards in Turkey, Greece, Italy, Spain, and Croatia to specialize in specific components.
- Their first pilot, a three-megawatt floater, is being assembled for installation in the North Sea in spring, through a partnership with Archer Wind. Dominique says the industry will reach pre-commercial projects of 100-200MW in France, UK, Norway, Japan, and Korea that, once completed successfully, will unlock gigawatt-scale commercial projects after 2030.
