Deepening Scheme on Delaware River Enters Blasting Phase

The U.S. Army Corps of Engineers, Philadelphia District, and its contractor Great Lakes Dredge and Dock Company began rock blasting operations last month as part of the project to deepen the channel of the Delaware River.

This phase of the program involves fracturing of rock by controlled underwater blasting so it can be removed mechanically.

After blasting, rock is being removed by using mechanical dredging (typically bucket dredging) and placed at Fort Mifflin.

This capital development project involves dredging as needed within the existing 40-foot Delaware River federal navigation channel to deepen it to 45 feet from Philadelphia Harbor, Pa. and Beckett Street Terminal, Camden, N.J. along a 102.5-mile distance to deepwater in the Delaware Bay.

More than 16 million cubic yards of material must be removed during initial construction. Of that amount, approximately 12 million cubic yards of silt, clay, sand and gravel will be dredged from the river portion of the project.

The remaining 4 million cubic yards is primarily good quality sand from the Delaware Bay, half of which is being dredged and placed for initial construction of the Corps’ coastal storm damage reduction project (dune and beach nourishment) at Broadkill Beach, Del.

The Delaware River dredging scheme is slated for completion by the end of 2017.

3rd International Congress Hydraulic Engineering Structures and Dredging

Russia’s leading maritime industry Media Group PortNews (www.portnews.ru) holds a traditional annual Congress “Hydraulic Engineering Structures and Dredging” in Moscow. 

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
