Case studies · 2019–2026

Selected work. One engineering method.

A curated set of projects we've shipped, are sailing, or are being built right now. From luxury cruisers to tuna seiners, from polar-class cruise to the world's largest cruise ship — and from floating-wind foundations to live-fish carriers. willbö runs concept, basic, detail and production on the same platform, with the same team in Vigo and Mumbai.
