Current underwater systems utilize pressure vessels for electronic parts. This is less robust and incurs high maintenance. Besides, such systems cause significant problems in the extreme deep-sea environment. The other limitation is their low power density that results in large and expensive dimensions of the parts. The project aims to solve these challenges while developing an innovative system for pressure tolerant high voltage deep sea platform without using any mechanical switch contacts. The system should be able to operate at full ocean depth. Such solutions can be used for offshore oil and gas equipment, marine mining, offshore wind farms, marine biology, underwater vehicles and other subsea applications.

FormLED company with its subsea brand Aequonics functions as the project manager. Technically, FormLED / Aequonics is responsible for developing of the pressure tolerant technology for electronic assemblies, particularly energy storage with high energy density, battery management system (BMS) for Li-Poli cells systems, power circuit breaker with semiconductor components 110 V, 100 A, charging converter for returning the energy, LED lighting / LED flash without color shift, optical control system of the high-voltage demonstrator.
