Side scan and bathymetric surveys of the Marine Group Boat Works yards were completed by Orca Maritime using an Iver3 AUV equipped with an EdgeTech 2205 sonar.
Marine Group Boat Works is a full service boat and superyacht refit and repair facility with two locations on the San Diego Bay.
The survey was conducted with boats tied to the docks and no interruption to regular business for either boatyard. The complete survey of the National City location was conducted with 2.5 hours of track lines and Chula Vista with 1.5 hours of track lines. Each site presented a complex area with infrastructure and boats hulls to survey around and under. The AUV, equipped with an INS essential for underwater nav accuracy in tight quarters, was able to run at depths optimal for the range and frequency needed to maximize coverage and data resolution.
