Our Story
Behind OEK Marine
I founded OEK Marine to offer shipyards and design offices something rare: the precision of a senior engineering team, with the speed and flexibility of an independent partner.
With over a decade of naval architecture and project execution experience, I help clients turn early concepts into build-ready solutions — combining Dutch engineering standards with AI-assisted workflows that reduce bottlenecks and keep projects moving.
Today, I support companies across Europe as an external engineering lead, delivering clarity, technical confidence, and scalable capacity whenever needed.
