MONROE TOWNSHIP, New JerseyOcean Power Technologies Inc.’s PB3 PowerBuoy has surpassed 600 days of continuous operation for Eni’s Phase 1 resident AUV project in the Adriatic Sea.

Initially leased by Eni in 2018 for an 18-month mission to convert wave energy into electricity for powering underwater vehicles, the PB3 PowerBuoy lease was extended in March 2020 for an additional 18 months.

To date, this system has produced more than 2.7 MWh since it was deployed. The power takeoff (PTO) – the company’s patented wave energy conversion system that converts ocean wave motion into rotary motion to drive a generator – has made more than 3.5 million cycles.

Over the past four years, the company said it has put several PTO systems through both ocean-based and factory accelerated life testing, accumulating more 40 million cycles among them.
