EvoLogics underwater acoustic modems were recently listed as Authorized for Navy Use (ANU), following a lengthy period of testing and technical evaluation by Naval Sea Systems Command (NAVSEA) and The Emergency Ship Salvage Material (ESSM) System. The ANU Program provides a list of selected diving equipment, tools and accessories which have undergone design safety reviews, testing and evaluation to ensure diver safety and acceptability.
Engineers at ESSM who conducted the testing of the EvoLogics 18/34 kHz USBL modem system concluded “the system to be more accurate than our ability to physically measure the angle and distances between the USBL and the modem…these tests gave us confidence in the system.”
The investigation of EvoLogics USBL positioning system was driven by ESSM in hopes of more efficiently locating fuel tanks in submerged shipwrecks for oil salvage. Specifically, ESSM were hopeful to use the system to locate fuel tanks on the wreck of the Prinz Eugen, a German battleship sunk in 1946 at Bikini Atoll.
