dc.descriptionThe Savannah District (SAS) is preparing a Final Engineering Appendix for the Savannah Harbor Expansion project. Initial vertical motion studies addressed extension of the entrance channel to deeper water along the existing alignment. After initial channel design, shallower offshore shoals were identified that could influence the safety and efficiency of navigation on the proposed channel alignment. The U.S. Army Engineer Research and Development Center (ERDC), Coastal and Hydraulics Laboratory (CHL), conducted a vertical ship motion study to evaluate three proposed channel alignments: S-1, S-3, and S-8. These alignment changes (doglegs) are proposed to allow ships to reach deeper water in less distance, with reduced dredging costs. The Channel Analysis and Design Evaluation Tool (CADET) was used to predict vertical ship motions due to wave-induced heave, pitch, and roll. PIANC and Ankudinov ship squat were calculated and compared with the CADET squat predictions. The CADET days of accessibility, vertical ship motion allowances, and net underkeel clearance were calculated based on these vertical ship motion components to provide a risk-based method of evaluating different channel depths.-
