SUBSEA BATTERY

The Ocean Power Technologies Subsea Battery solution is an economical and reliable way to power subsea payloads.

Energy is stored in high capacity, zero-maintenance, and environmentally friendly (no heavy metals) lithium-iron phosphate (LiFeP04) batteries. The solidly constructed all-steel pressure vessel is designed to ASME standards for a 10-year life and is rated for up to 500 meters maximum water depth.

The Subsea Battery solution features 132 kWh total nominal capacity with up to 15 kW peak power delivery.

LiFeP04 batteries have extremely low self-discharge rates while in standby mode, storage or transport, as compared to other chemistries. ?OPT’s proprietary, highly efficient control and battery management systems further maximizes the amount of energy available for payloads, allowing the battery to remain in an active state longer than conventional battery designs.

Under normal operating conditions the Subsea Battery solution supports thousands of charge/discharge cycles. Designed to integrate with OPT’s PB3 PowerBuoy® and hybrid PowerBuoy® products, the Subsea Battery solution can also be utilized as a standalone power source or can be configured for recharge by other sources.

Some of the importance of the products offered by OPT is the elimination of carbon emissions that supporting surface vehicles produce. Additionally there is money saved, no safety concerns for a crew by not having a ship and crew floating in support of
operations.

Best to all.
