OSEAN 's expertise is based on a team of experienced and passionate engineers and technicians working with state-of-the-art equipment. OSEAN carries out studies in the following fields: electronics, computer science, optics and mechanics. OSEAN is committed to producing the most robust and reliable products in the respect of safety and quality required by the defence or scientific field.

In order to carry out the tests of its submarine systems, OSEAN has a semi-Rigid 7.5m type boat based in the harbor of Toulon.
