The PB3 supplies power continuously to on-board payloads or equipment located on the seabed while also providing real time data transfer and communication to remote shore facilities. The PB3 is sized and designed to store sufficient electric energy to provide reliable “ride through” power in extended periods of flat-calm seas.

The PB3 supplies power continuously to on-board payloads or equipment located on the seabed while also providing real time data transfer and communication to remote shore facilities.

The conversion of wave energy into electric power is carried out through a direct drive generator that continuously charges an on-board battery pack (Energy Storage System). Power from the battery is delivered to meet application and end-user needs. This is particularly advantageous for applications that have varying power requirements including continuous and larger occasional peaks.

OPT has designed the PB3 to minimize operational costs (OPEX) whereby deployment and recovery thereof is simplified, leveraging vessels widely employed in offshore marine operations. The PB3 can be either towed to site or deployed from a vessel’s deck.

Maintenance intervals, by design, are every 3 years. The PB3 control and management system includes self-monitoring data collection, processing and transmittal to allow pro-active maintenance strategies, thus increasing availability and operational effectiveness.

The PB3 technology was demonstrated for a US Navy project to provide power to coastal security networks and survived rigorous sea trials, including operation off the New Jersey coast through Hurricane Irene in 2011. Exterior payloads are anticipated to be shipped in the ISO shipping container and would re
