The U.S. Army Corps of Engineers, New England District, awarded the $9.3 million contract to Cashman Dredging and Marine Contracting Company of Quincy, Mass. The work will be performed over a three to four months between Oct. 1 and Jan. 31, 2018, for shoals inside Milford Point, and between Oct. 1 and Feb. 28 for shoals seaward of Milford Point.

The last dredging of the Housatonic was in November 2012 when the Corps’ dredge Currituck removed about 50,000 yards of shoal material. This project will take nearly 300,000 cubic yards(a cubic yard of sand weighs nearly three tons) of clean, fine sand from the Housatonic’s shallow navigation channel and move it to Connecticut’s premier beachfront park, Hammonasset Beach State Park in Madison.

The sand will be transported by barge to re-nourish the eroding beach at Hammonasset and this will really improve the beach up at Hammonasset. The Connecticut Port Authority has followed through with the finding for this project.

Jenkins Marine has been assisting BAM Nuttall with the new £10 million quayside construction development in Poole harbor (the South Quay Project).

The new quay will need approximately 1,800 tons of steel piles, all of which will be delivered by sea. Jenkins Marine is also providing assistance with demolition work for existing structures, dredging, and additional piling barges.

The project, which is due for completion by the end of 2017, will ensure that the Port remains competitive with facilities that can accommodate a much wider range of shipping and marine activities.

The expansion of the port will be able to accommodate vessels up to 220m long in a variety of different sectors including yacht transportation, bulk cargo, short sea containers and project cargo.

Transnet National Ports Authority (TNPA)’s Dredging Services division has embarked on a $ 1.1 million maintenance dredging campaign at the Port of Cape Town to restore the design depths inside Duncan dock.

The maintenance dredging work, which began on March 8, 2017, is scheduled for completion by the end of April 2017. The main objective of the dredging work is to ensure the Port of Cape Town provides safe navigational channels and berthing facilities for shipping by restoring the original design depths.

Two dredging vessels, the Isandlwana, a Trailing Suction Hopper Dredger, and the Italeni Grab Hopper Dredger have been mobilized by TNPA Dredging Services for this purpose.

The Isandlwana, which has a 4,200 m³ hopper capacity, will remove approximately 70,000 m³ of material from the sea bed before the end of April. Spoil is pumped into the hopper and can be offloaded by discharging through 10 conical bottom valves. Pumping ashore is also possible by means of either a floating pipeline, a side discharge mechanism or by ‘rainbowing’, where the dredging vessel discharges material that has been claimed from the ocean floor in a high arc to build a landmass elsewhere, such as during nourishment of beaches, to prevent erosion along the coasts or to reclaim land.

TNPA’s fleet renewal program has boosted the dredging division’s capacity to aid the removal of approximately four million cubic meters of excess material from the seabed every year at South Africa’s ports.
