MONROE TOWNSHIP, New Jersey – Ocean Power Technologies Inc. (OPT) has unveiled the Subsea Battery solution.
This is said to be an environmentally friendly lithium-iron phosphate battery system with a nominal storage capacity of 132 kilowatt-hours. It uses the company’s proprietary battery management system which maximizes the amount of energy available for subsea payloads.
The all-steel pressure vessel is designed to ASME standards for a 10-year life and is rated for up to 500 m (1,640 ft) maximum water depth.
The new system is said to provide uninterruptable power for long-term offshore installations requiring electric power, backup or emergency power for short-term missions, and is scalable with multiple units to meet higher energy needs.
George H. Kirby, president and CEO of OPT, said: “The ongoing electrification of subsea assets requires reliable power that can scale to meet the needs of the offshore industry.”
Integration with the company’s PowerBuoy products creates ocean-based autonomous power solutions for subsea oil and gas production systems, aquaculture systems, environmental sensors, and powering ROVs and AUVs.
