Surveillance allows with different levels of answers the protection of infrastructures and sensitive sites (submarine bases, ports, wind farms, submarine cables, shock point, border control). It prevent against the intrusion of unmanned underwater vehicles or enemy divers, who can threaten to these installations.

The water column can be used to illegally transport goods or people. Surveillance can help fight against drug trafficking, arms smuggling, and other illegal activities.

Surveillance can be undertaken with the installation of instrumented, connected stations. Information management is achieved via data recording or real-time transmission to detect and report any change of activity.

In an era of evolving threats, mastering sound waves is not just an advantage—it’s a strategic necessity.
Why Underwater Acoustics Matters :
Acoustic systems enable navies to detect enemy submarines, secure communications between units, and monitor sensitive areas often beyond the reach of radar. In the vast, opaque underwater environment, sound remains the most reliable medium for gathering intelligence and maintaining operational awareness.
Key Challenges :
Harnessing underwater acoustics is fraught with obstacles: ambient ocean noise, multipath interference, limited bandwidth, and the critical need for stealth to avoid detection. These challenges demand continuous innovation and precision engineering to ensure effective and covert operations.
Sercel: Leading the Way :
Among industry leaders, Sercel stands out for its expertise in underwater acoustic solutions. By developing cutting-edge technologies, Sercel addresses the critical needs of navies worldwide, delivering systems like underwater acoustic modems that combine high performance with the discretion required for modern naval operations.
As maritime challenges grow, underwater acoustics remains an invisible yet decisive asset for national security and sovereignty.
 

Operators in oil and gas, ports, and offshore windfarm environments need to optimize vessel movements and schedules while also maintaining situational awareness of all operations. The Marlin Application Suite addresses a range of marine operational challenges, including methods for linking charter information, vessel plans, tasks, schedules, and positions to past, present, and future offshore activities.

Monitoring the Earth and the oceans is a major challenge for the preservation of our environment and the management of natural resources. It makes it possible to monitor climate change, natural phenomena such as hurricanes and earthquakes, as well as the evolution of marine ecosystems. Finally, it plays a crucial role in the mapping and management of territories for the sustainable use of land and marine resources.

The energy transition is necessary to reduce our dependence on fossil fuels, which are responsible for greenhouse gas emissions and climate change. By adopting renewable energy sources such as solar and wind power, we can lower our carbon footprint and preserve the environment for future generations. Moreover, the energy transition promotes technological innovation, creates new economic opportunities and improves the resilience of our energy systems.
