The D-Sea battery pack delivers power for underwater assets. Its 400V output is matched for Heavy-Duty applications at 1000m below sea level. The Immersion Fluid Cooling System enables quiet and cool operation for the most demanding tasks.
Introducing the
D-Sea

Subsea Battery Pack
Applications
Standalone Power
On its own, the D-Sea battery pack can be used to supplement ROV & Diver operations. In IMR projects – it can be used to replace a topside supply, eliminating the need for vessel-mounted generator, HPU, winch and chute.
Integrated Power (Mobile)
The D-Sea battery pack can become an integral part of a subsea vehicle power system. For ROVs – it can be used to mitigate power demand and increase payload. For AUVs, it will offer prolonged mission capability, faster propulsion and greater distance covered.
Back-up Power
When mounted along the primary power source, the D-Sea can provide emergency power to enable continuous operation in the event of equipment damage / failure.
