For Immediate Release – March 14, 2019:

Phoenix International Holdings, Inc. (Phoenix), in partnership with Underwater Acoustic International, L.L.C. (UAI) and Ocean Tech Services (OTS), mobilized a sonar team and Remotely Operated Vehicle (ROV) team to the Wishon Reservoir to perform a comprehensive underwater acoustic imaging and visual inspection of the Wishon Dam for the Pacific Gas and Electric Company (PG&E). The intent of the inspection was to collect a baseline of current conditions to enable planning for effective repair and remediation. The acoustic imaging was accomplished utilizing a high resolution Underwater Acoustic Steered Beam Imaging system from UAI. The visual inspection was performed using an inspection class ROV. Operators maneuvered the ROV along the dam face to collect visual images of areas identified in the acoustic imaging inspection. The results of this acoustic and visual inspection were provided to PG&E within a 100+ page report that included mosaic images of the acoustic data and visual images from the ROV to provide a clear picture of the underwater condition of the dam.
