Who we are
A new company, built on years of research.
Turnavi was founded in 2024, but the methods behind it are not new. They took shape over years of doctoral research and academic-industry projects, where we developed the numerical methods for how structures move, vibrate and resonate in water. We are engineers and researchers who came together to bring that rigor to the field, from defense to renewable energy.
Our story
It started in the lecture halls, not the marketplace.
Turnavi's roots lie in doctoral research at Istanbul Technical University's Faculty of Naval Architecture and Ocean Engineering. Our first real collaboration between academia and industry began with the İSATAR project; that experience sparked the idea of taking the work further, and grew into our TÜBİTAK 1005 and 1812 (BiGG) projects. We did not leave the numerical methods we developed for fluid–structure interaction on the journal page; based at İTÜ ARI Teknokent, we built Turnavi to turn methods proven in research into engineering that industry can put to work.
Our expertise
One question runs through all of it: how structures and water act on each other.
Our depth is in fluid–structure interaction, the meeting point of computational mechanics and the sea. We model the motion, vibration and acoustics of a structure as one coupled problem, rather than four separate ones. That foundation is why a single core reaches across so many fields: the hull of a ship, the leg of an offshore platform and the float of a solar array are, to the physics, the same question asked in different waters.

How we work
Rigor first. No black boxes.
We start from the method, not a menu of features. Every result we hand over rests on assumptions we can defend and a method whose basis we can show, because in critical work, a number you cannot trace is a number you cannot trust. Where standard tools fall short of the problem, we build the solver that meets it. That is the difference between owning your method and renting a foreign license.
