Underwater Electromagnetic Sensing & Imaging Solutions

CEDAR – state-of-the-art electromagnetic sensing and imaging technology

Our CEDAR (Controlled Electric Detection And Ranging) technology is inspired by the electrical sensory perception of tropical freshwater fishes, which use this unique capability to navigate, hunt prey, and communicate with each other in challenging environments where sight and echolocation are ineffective.

CEDAR generates a low-frequency AC electric field that is disrupted by objects in the near vicinity, causing changes in current intensity. These disturbances can be measured and used to characterize the underwater environment even in the murkiest of conditions.

Octopulse

Underwater imaging solution for subsea vehicles and fixed installations

Underwater imaging solution for subsea vehiclesOctopulse is a compact and lightweight imaging sensor based on our proprietary CEDAR technology, and is ideal for both underwater vehicles and fixed-site applications. The modular system utilizes an array of up to eight electrodes with cables up to 7 metres in length, and provides 360-degree real-time perception.

Seabed imaging solutionThe sensor provides highly effective detection, localisation and classification of both metallic and non-metallic objects as well as buried targets. It delivers excellent performance in noisy environments and high levels of sediment, and works in freshwater and saltwater environments as well as in air. With no moving parts, it requires very little maintenance and can be used for contactless characterisation of any kind of surface or material. The system’s low power draw makes it ideal for long-term deployments requiring little maintenance.

subsea imaging sensorThe export restriction-free Octopulse is provided as a complete kit comprising the sensor pod, up to eight electrodes and cables, and all necessary firmware and user interface software. It is currently available as a 300 metre depth-rated version, with a 6000 metre-rated version under development.

Applications

Survey & Monitoring

Survey & Monitoring
Thanks to its contactless detection and characterization abilities, Octopulse is ideal for underwater surveying and monitoring applications, including cable and pipeline tracking and oil and gas infrastructure maintenance.

Critical Infrastructure Security

Critical Infrastructure Security
With highly sensitive detection capabilities, Octopulse can be installed underwater to detect intrusion at critical port or waterway facilities such as docks, oil terminals, and nuclear power stations.

Archaeology & Salvage

Archaeology & Salvage
Octopulse can pick up metallic and nonmetallic objects on the sea floor or buried in the sediment, making it an excellent solution for surveying cultural heritage sites, structural remains and shipwrecks.

mine detection

UXO & EOD
Able to detect both ferrous and non-ferrous objects at depths of 1 to 2 metres, Octopulse supports commercial and naval dive teams in clearing unexploded ordnance, mines and underwater hazards. The system has recently been selected for NATO’s DIANA technology accelerator program.

ROV & AUV Navigation

Underwater Vehicle Navigation
With an effective detection range of up to 5 times the length of the vehicle, Octopulse can be combined with cameras and sonars for enhanced vehicle navigation and obstacle avoidance.
