An ocean network of unmanned vessels

The company develops both vessel hardware and the software that coordinates it. Its planned network distributes unmanned surface vessels across the sea, combining communications control and energy management so they can operate as a coordinated monitoring system.

Moving beyond demonstrations

The company announced the financing in January, with payment scheduled for early February. It is integrating hardware, software and business development to turn demonstrations into an operating marine network, with commercialisation planned for 2027.
