Spinoff from Ecole Centrale Nantes (French engineering school) / CNRS (National centre for scientific research)

HydrOcean was created from and is supported by the Fluid Mechanics Laboratory of Ecole Centrale Nantes (ECN UMR / CNRS). HydrOcean and ECN have set up a highly efficient research partnership, which aims at promoting the most innovative research tools developed in their laboratory and also making them accessible to industrial partners in the form of service provision or through user licenses.

Bureau Veritas acquires HydrOcean

We are pleased to announce that on September 8th, 2015 HydrOcean was acquired by Bureau Veritas. Bureau Veritas is a large and diverse group, headquartered and listed in Paris, with a market capitalisation of circa €9 billion. Created in 1828, the Group has more than 66,500 employees in around 1,400 offices and laboratories located all across the world. Bureau Veritas helps its clients to improve their performance by offering services and innovative solutions in order to ensure that their assets, products, infrastructure and processes meet standards and regulations in terms of quality, health and safety, environmental protection and social responsibility.

Didier Michaud-Daniel, CEO of Bureau Veritas commented "The acquisition of HydrOcean enables Bureau Veritas to integrate an outstanding team of experts and highly innovative entrepreneurs. The Group is increasingly developing solutions combining its core testing, inspection and certification services with new technologies. HydrOcean fits perfectly into this strategy thanks to its simulation tools and its technical expertise. Its services will complement those offered by the Marine & Offshore business, especially in reducing ship fuel consumption".

Erwan Jacquin, President and founder of HydrOcean said "We have already achieved successful projects with Bureau Veritas, under the technical and commercial cooperation agreement we have had for over a year. Today, we are looking forward to becoming part of one of the world's leading classification societies and expanding our business into the international market".

Innovative numerical hydrodynamics tools

ICARE is a computational code that solves Navier-Stokes with free surface equations. It is the quickest and most accurate software for resistance, propulsion, maneuverability or sea-keeping applications.


VOF-flow is a RANSE solver with free surface computed with a VOF algorithm. It allows computations on the most complex geometries and is extremely robust.READ MORE >>

SPH-flow is our most innovative solver, dedicated to hydrodynamic impacts, fast dynamic simulations, and moving or deformable bodies ...READ MORE >>
