SIREHNA is a subsidiary of Naval Group (French naval system integrator). SIREHNA operates in various fields of expertise such as hydrodynamics and control of mobile maritime units. Those skills are directly applied to maritime embedded systems such as Dynamic Positioning Systems, Unmanned Surface Vessels or critical tailored systems such as the French aircraft carrier flight deck tranquilization system. Those embedded systems include software components which perform many functions such as real-time computation of navigation data, multi-degree of freedom control algorithms, actuators orders and supervision of the system by human operators. These systems are embedded on offshore vessels, cruise vessels, mega-yachts, military ships... Since they play a key role in the safety of multiple installations, they undergo a rigorous development, verification and validation process. SIREHNA also performs hydrodynamic studies and simulations, in order to either help design new products, or to improve already existing ones, in terms of performance or fuel consumption for instance.
