Technology for the future

Reduces the number of parts that need to be installed and minimizes the necessary modifications to the vessel’s hull. The sophisticated all-in-one transducer measures all required parameters through a single hull penetration, saving time on both installation and occasional maintenance.

Our solutions allow for the use of standard low-voltage cables down to the sensor, unlike traditional systems that require expensive, high-power cables with restrictive routing.

Digital signals from the transducers allow easy extension or cutting of cables without affecting performance.

A cost-efficient alternative to traditional tanks and sea valves for transducers, approved as "closed-ended installation." There is no need for piping above the waterline or additional safety measures for water integrity. Its compact design allows for easy fitting in tight spaces. With the Easy Tank, transducer replacement can be carried out from inside the hull, with a diver covering the hole from the outside—unlike other tanks that require external installation.

Our logs utilize Acoustic Correlation to calculate speed, offering robust, interference-resistant performance. This ensures reliable integration with systems like radar, autopilot, and fuel optimization. Unlike other solutions, Acoustic Correlation is independent of water temperature and salinity, requiring less calibration and delivering unparalleled measurements anywhere in the world.

Our technology delivers unparalleled precision in speed measurement, which is critical for onboard fuel optimization systems. By providing accurate data, our speed logs help vessels reduce fuel consumption, lower operational costs, and enhance overall efficiency.

Thanks to low-power digital communication and intelligent acoustic signal sequences, our speed logs and echo sounders provide highly accurate measurements while significantly reducing impact on the environment. By lowering sound pressure in the water, they help protect marine life, making them a sustainable choice for the future of maritime navigation.

By using fewer materials during installation, our products help lower the overall carbon footprint, supporting more sustainable maritime operations. The low power consumption of our solutions further enhances efficiency, reducing energy use and environmental impact.

The installation of our combined transducers requires minimal hull modification, resulting in enhanced fuel efficiency and optimized vessel performance. Tested and verified by SSPA, now part of RISE.
