Marine Services :: Infrastructure Inspection

DEA has been on the forefront of high-resolution multibeam bathymetric survey technology for monitoring underwater structures since the early 1990s. We evolved this service to monitor stilling basins, dams, and coastal navigation structures using a variety of methods including:

  • Surface-based, high-resolution multibeam sonar
  • Underwater scanning bathymetric sonar
  • Remotely Operated Vehicle (ROV) video inspections
  • Above-water, high-definition laser scanning
  • Sub-bottom profiling
  • 3D modeling
  • Acoustic Doppler current profiling

These types of surveys have been performed for the USACE, the Waterways Experiment Station (now the ERDC Coastal and Hydraulics Laboratory), hydropower companies; Port Authorities; and state Departments of Transportation. The USACE mission of monitoring underwater structures and evaluating erosion areas before they become a problem requires quality data with highly accurate and precise horizontal and vertical positioning. DEA has been chosen to perform this work based on our demonstrated ability to fulfill USACE’s objective of precision monitoring.
