Reliable and resilient subsea power
Overview
Enabling resilient subsea operations through a rechargeable subsea battery solution
Charge is a rechargeable, seabed-based battery unit engineered to deliver dependable, autonomous power for a range of subsea applications such as:
- Subsea Monitoring and Instrumentation
- Backup / Redundancy to Umbilicals
- Brownfield Power Remediation
- Short-Term Missions/Temporary Deployments
A new way to power up
Charge is an integrated subsea power solution that uses Kraken Robotics’ SeaPower pressure-tolerant battery modules.
SeaPower batteries are built around high-capacity lithium-ion pouch cells, delivering an impressive energy density of up to 260 Wh/l and 145 Wh/kg, with a consistent density of 2 kg/l.
Charge is available in small, medium and large configurations with varying voltage outputs. The pressure-neutral SeaPower battery design delivers up to 2x the energy density at 46% less weight in water per kWh when compared to traditional oil compensated, pressure-housed batteries.
Resilient subsea power solution
Operating at depths of up to 3,000m or greater, Charge is ideal for subsea power delivery problems that require rapid solutions.
To guarantee enhanced operational range and dependability, each battery unit undergoes rigorous pressure testing to full operational depth. Such extensive testing ensures that the batteries are not only reliable but also durable under the extreme pressures of deep-sea environments.
By eliminating the need for permanent cabling and enabling “plug-and-play” subsea power, Charge helps clients to reduce costs and extend asset life, while supporting the growing shift toward autonomous and digital subsea infrastructure.

Charge Applications
-
01. Brownfield Power Remediation
Deploying to fields where extensions, modifications or repairs are ongoing and power delivery is needed temporarily.
Case Study: A Canadian oil and gas operator required a temporary, autonomous power solution to maintain insulation resistance (IR) protection for subsea umbilicals. Charge was provided for a project in the harsh conditions of the North Atlantic, where a scheduled disconnection of the FPSO vessel posed a significant risk to powering existing subsea infrastructure.
-
02. Underwater Instrumentation and Data Logging
Charge can be used to prolong operating duration of underwater instruments and measuring equipment, through using it as a supplementary power supply or uninterrupted power supply. Extending the installation periods for ocean monitoring equipment, like ADCPs, means less change-outs – improving data quality and reducing costs of long-term monitoring.
Case Study: In the US Gulf, Charge was provided to support an offshore Monitoring Service company who required a short-term, autonomous power source to support an environmental monitoring system for oil leak detection.
