Project Overview

The South Carolina State Port Authority (SCSPA) is building the only permitted new container terminal on the US East and Gulf Coasts. ATM was approached to join AECOM’s team responding to a design RFP for the Hugh Leatherman Terminal development. Our team was successful and was selected by the SCSPA to develop the terminal design.

ATM’s role is to provide coastal engineering support services for the required dredging at the new terminal face. In addition to providing specialized support services, ATM will complete a sedimentation study to ensure the project design will minimize, to the extent practicable, future maintenance dredging requirements. As part of the study, ATM will collect field data including current velocities (ADCP) and collect suspended sediment data both of which will be utilized to calibrate a 3-D sedimentation model (EFDC).

The 250 acre and $750 million terminal is expected to open in 2019 providing 52 feet of water at the berths.This will effectively give the port the deepest harbor on the US East Coast with capability of berthing the ever-increasing container ship lengths transiting the expanded Panama Canal.
