Tailored products for naval applications!

Essential meteorological and electrical surveillance solutions for the propulsion and navigation functions of military ships and submarines.

Our strengths in the naval sector


Meteorological sensors (Capteurs météorologiques (rotating vanes, anemometers, hygrometers, etc.), temperature measurement, measurement and supervision systems: a team of specialized engineers and technicians design our innovative, tailored systems to meet the very specific needs of industrial companies and government administrations (navy and national defense).

Chauvin Arnoux Energy helps all the players in the naval sector with digital meteorological systems and wind systems for collecting and distributing highly accurate meteorological data.

The versatile repeater is part of a modular system which is totally configurable and upgradable for remote collection of all the meteorological data via an Ethernet link or digital links.


A dedicated team accompanies you during your project, offering the guarantee of a system perfectly suited to your requirements. On the basis of specifications, our engineers develop products from the design phase through to their implementation on site. Advice on equipment development, commissioning, instrument configuration and operator training: our team can examine, quantify and complete any "turnkey" projects in accordance with the most demanding needs of each customer. 


Chauvin Arnoux Energy has been designing high-performance systems for the French Navy for more than 30 years, equipping ports such as Marseille, Dunkerque, Le Havre, etc. Internationally, a large number of other national navies place their trust in us, such as Chile, India, Malaysia, Brazil, etc.
