Evaluating the Effects of Increased Dredge Depths on Existing Structures
As vessels increase in size, ports require enhancements and modifications to existing facilities. A primary factor in determining facility limitations is the posted dredge depth. For this reason, the Port of Virginia performed a dredge deepening study at Portsmouth Marine Terminal. This terminal contains a wharf, 4,500 ft long × 70 ft wide, constructed in three phases with multiple unique pile-supported cross-sections. Existing dredge depths measure between 40 and 42 ft below MLW; however, the desired dredge depth is 46 ft below MLW. Increasing the dredge depth may be a beneficial upgrade but requires many factors to be considered. The primary impacts included the effect on the point of fixity and effective length of the foundation piles, decreased geotechnical pile capacity, and potential impacts to the bulkhead wall along the landside edge of the wharf. These conditions were evaluated for the various cross-sections of the wharf.
