ESP mobilized survey vessel “Eridanus” and a shallow draft recon vessel to complete hydrographic surveys along the I-10 corridor crossing Mobile Bay for the Alabama Department of Transportation. Survey vessel “Eridanus” our state-of-the-art hydrographic survey vessel is equipped with an Edgetech 6205 Interferometric Swath Bathymetry Sonar and Applanix POS MV 320 Ocean Master positioning and motion sensing system.

The project involved single and multibeam bathymetric data collection along the existing I-10 dual bridge eight-mile alignment and within a portion of the Port of Mobile. Our survey vessel was utilized to collect full-bottom multibeam bathymetry for all deep water portions of the project. Multibeam data was collected on the Blakely, Apalachee, Tensaw, Spanish, and Mobile Rivers and along portions of the old barge canal constructed between the existing I-10 bridges.
