Before-Dredge and After-Dredge Multibeam Hydrographic Surveys

Originally, McKim & Creed was hired to perform a before-dredge (BD) and an after-dredge (AD) multibeam hydrographic survey at the Hugh K. Leatherman Sr. Terminal at the SC Ports Authority. Deliverables included a map and a volumetric report of each survey.

As the project progressed, the contractor encountered a few obstacles due to the dynamic environment. This resulted in 10 additional progress surveys being performed. Some of the surveys were requested at short notice by the client and McKim & Creed was able to fulfill the tasks with no issues. Each of the surveys included a map presenting the hydrographic survey and a thorough volumetric report created in AutoCAD and compared with Hypack results.

Furthermore, dual-frequency single beam surveys were performed to evaluate the fluff layer that was being formed in the dredging location, as per client’s request.
