SIREHNA
Since 1986, SIREHNA has been designing and developing high-tech solutions for the maritime sector.
A 100% subsidiary of Naval Group since 2012, the company relies on recognized expertise, advanced technological know-how, and a strong culture of innovation. With nearly 150 employees, SIREHNA operates in France and internationally, making naval platforms more autonomous, stable, efficient, and intelligent.
The company supports its clients in developing intelligent and reliable solutions, optimizing performance and maritime operational safety. Backed by its recognized expertise and a constant commitment to innovation, SIREHNA continues to create solutions that shape the future of marine environments.
SIREHNA’s activities cover five key areas:
- Engineering and consultancy services: designing and optimizing naval platforms
- Autonomous vessels: developing intelligent navigation systems
- Testing and experimentation: validating innovative solutions under real-world conditions
- Platform dynamics: improving stability and performance
- Enhanced perception: processing data and providing decision-support solutions
The DP SIREHNA system is a certified, fully customizable dynamic positioning system (DP0, DP1 and DP2) with joystick control system as well as a trajectory control system (TCS).
At low or high speeds, the SIREHNA dynamic positioning system and autopilot automatically maintain the vessel’s position and heading using the propulsion already installed on board.
Position reference sensors, combining wind sensors, motion sensors (roll, pitch) and gyroscopic compasses enable the computer to calculate the control laws required to maintain the vessel in the desired position or course.
The standard control modes available are: Joystick Manual, Joystick Auto / Combined, Station Keeping and Auto-Track.
The standard control modes available are.
Other modes or features can be added for specific applications: Follow Target, Auto Area, Anchor Mode, Jack-up Function, Onboard Training, Onboard Capability plot and Heading / Track Keeping (high speed).
The SIREHNA maritime optronic surveillance system, MOS, offers automatic detection, tracking and geolocation of any potential threat on the surface.
MOS can detect moving or stationary objects appearing anywhere within a radius of 0.5 m to 200 m, whatever the sea conditions (up to force 4+).
MOS offers automatic camera tracking and identification, as well as real-time analysis based on specific criteria (position, speed and trajectory).
MOS consists of one or more graphical interfaces with video display, radar view, alarm monitoring and zoom. MOS can display up to 6 thermal cameras, with video stream analysis, pan/tilt zoom control and 360° coverage.
