Unlocking the Power of Li-ion Energy Storage Systems

Engineered for high-demand energy applications exceeding 1 MWh, Energy Storage Systems (ESS) are tailored to function as either a primary or backup power source for offshore facilities, especially in locations where grid connectivity is impractical or unreliable.This design facilitates seamless integration with renewable energy sources, acting as a dependable energy reservoir for oil and gas operations, underwater sensor networks, and remote autonomous systems.

Each unit features fully API17F-compliant lithium-ion battery modules and meets UN T38.3 standards,ensuring adherence to stringent safety and transport regulations. The accompanying subsea skids are expertly designed and certified for resilience against pressure, temperature fluctuations, and corrosion, ensuring durability in challenging marine environments.

Our product lineup includes:

  • Battery Storage Skid (BSS) – The Battery Storage Skid (BSS) is a robust energy storage solution crafted for rigorous subsea and offshore environments, providing consistent and dependable power even in extreme marine conditions.
  • Converter Skid (Power Skid PS) – the Power Skid (PS) serves as the connection point between the user’s subsea equipment and the Energy Storage System (ESS). It links the Battery Storage Skids (BSS) and facilitates necessary interfaces.
  • Diagnosis & Charge Unit (DCU) – The Diagnosis & Charge Unit (DCU) is a dependable fast-charging unit capable of delivering up to 170 kW to recharge BSSs post-deployment. Furthermore,the DCU provides diagnostic capabilities for all components of the ESS.
