During trials, the Sabertooth owned by Hibbard Inshore and operated on behalf of C-Power, will repeatedly patrol pre-pro- grammed areas to collect data, before returning to an under- water docking station for cloud upload and battery recharge.

Included in the studies will be seabed analysis, ? sh densities, infrastructure monitoring and water-column data gathering.

The trials come in partnership with the U.S. Department of

Energy’s Water Power Technologies Of? ce, together with the

National Renewable Energy Laboratory and the U.S. Navy.

In particular, testing of the SeaRAY AOPS is included in the Navy’s Coastal Trident 2021 program, which is the larg- est port and maritime security undertaking in the nation.

For the trials, the Sabertooth was equipped with an R2Son-
