Sonartransponder

Underwater Collision‑Warning Acoustic Beacon

Autonomous acoustic collision‑warning transponder ensuring safe navigation around subsea infrastructure, with omnidirectional detection, BSH‑compliant signalling, long‑term monitoring, and flexible seabed or structure‑mounted installation options.

The Develogic Sonartransponder is an advanced acoustic collision‑warning system designed to protect underwater vehicles, including submarines and UUVs, operating near offshore wind farms, oil and gas structures, and other subsea installations.

Fully compliant with BSH regulations and NATO acoustic standards, it continuously monitors the acoustic environment and responds to pre-defined interrogation signals with omni-directional warning transmissions.

The system supports both autonomous (battery powered) and cabled (externally powered) operation, offering flexible installation as a seabed lander, fixed or magnetically mounted frame. Robust titanium/POM construction, self‑diagnostics, and multiple communication interfaces ensure reliable, maintainable performance in greenfield and brownfield environments.

The system is fully compliant with BSH requirements and NATO standard acoustic signals, using 8.1 kHz detection and 7–7.8 kHz transmission for reliable, standardised collision warning communication.

With optional external battery packs, the Sonartransponder supports up to 24 months of continuous acoustic monitoring and response in standalone mode.

It can be deployed as a seabed lander, mounted on subsea structures via magnets, or integrated via cabled power and communication. All options are suitable for greenfield and brownfield installations.

Communication is possible via electromagnetic link, acoustic gateway buoy, or expendable communication buoys (ECBs). All acoustic interrogations are logged and can be transferred onshore.

The system uses Titanium and POM housings, syntactic foam flotation, omni-directional transducers, and continuous self-diagnostics to ensure corrosion resistance, mechanical robustness, and stable long term performance.
