Great Lakes Dredge & Dock Corporation (NASDAQ:GLDD) - reported today that four of its dredging vessels, including three hopper dredges and one cutter suction dredge, along with other ancillary equipment, are currently working on the construction of sand berms off the Louisiana Coast in response to the oil spill caused by the Deepwater Horizon incident.
