New Work Dredging
Charleston Harbor Deepening
Charleston, South Carolina
This $125,000,000 deepening project involving three clamshell dredges is ongoing and on schedule.
Savannah Harbor
Savannah Harbor Expansion Project (SHEP) Inner Harbor Deepening
Savannah, Georgia
This recently completed project required pumping hard materials up to 8 miles away while working in one of the busiest shipping channels on the East Coast.
Delaware River
Delaware River Main Channel Deepening – Reach B
When we unexpectedly encountered large rocks that were too large to pump, we had to work with the Army Corps to find a solution. The careful placement of the rocks formed underwater reefs for fish habitat in the Delaware Bay.
San Juan Harbor
San Juan, Puerto Rico
Up to ten vertical feet of virgin hard limestone was removed without blasting using hard digging clamshell buckets. This increased the port’s container cargo capacity and their competitiveness.
Beach Re-nourishment
Sand Key
Clearwater, Florida
This beach fill project included shorebird, turtle and vibration monitoring while riding out a major hurricane.
Canaveral Sand Bypass
Brevard County, Florida
Sand Bypass System, Phase V
The dredge Charleston had to be positioned in the surf zone in water as shallow as 14 feet deep, so we could “relocate” the sand from the north side of the inlet to the south.
Prime Hook
Milton, Delaware
Pumping 25,000 gallons of sand slurry per minute we closed off an existing inlet before building the adjacent beach.
Fire Island Inlet and Jones Inlet
New York
Sandpiles were used to rebuild dunes and roads destroyed by hurricane Sandy.
Construction Dredging
Chesapeake Bay Bridge Tunnel
Chesapeake, Virginia
Called one of “the seven engineering marvels of the world,” construction began on the 17.5 mile Chesapeake Bay Bridge Tunnel in 1961. Norfolk Dredging’s responsibility, among the several dredging firms participating, was to construct the two tunnel trenches between Cape Charles and Virginia Beach, VA.
New Midtown Tunnel
Norfolk, Virginia
Extremely precise dredging alongside an existing and active tunnel was required to complete this $1.5 billion dollar project. Depths in excess of 90 feet were achieved to very tight tolerances for the placement of new traffic tunnels.
Southern LNG
Savannah, Georgia
Working in the very close proximity of an ongoing major marine construction project, we pumped over 3,000,000 cubic yards of material over 28,000 feet to create a ship berthing area out of what was previously dry land.
Boston Hub Line
Boston, Massachusetts
Rough winter weather and thick deck ice were just two hurdles to overcome as we dug hard material 120 feet deep adjacent to an active high pressure gas pipeline.
Maintenance Dredging
Delaware River
Philadelphia to the Sea
A strong current, high shoaling rates and contract shipping traffic are some of the challenges we faced in maintaining the 45 foot channels of the Delaware River.
Norfolk Naval Station
Norfolk, Virginia
Removing approximately one million cubic yards of material from the Navy piers was required to safely keep afloat our nation’s warships, including the brand new carrier USS Gerald R. Ford.
Canaveral Harbor
Brevard County, Florida
The clamshell dredges ATLANTIC and VIRGINAN dredged over 600,000 cubic yards of material with offshore disposal while making special efforts to avoid the many manatees and sea turtles in the project area.
Baltimore Harbor
Baltimore, Maryland
Millions of cubic yards of maintenance material are hauled up to 35 miles in scows and then hydraulically unloaded at the Poplar Island material management site.
