Donjon Marine Co., Inc., based out of Hillside, New Jersey, was awarded a 1,000,000 yd³ dredging project in Port Newark, New Jersey, earlier this year by the United States Army Corps of Engineers.

The primary dredging unit, Michigan - a three (3) spud cable dredge - is owned and operated by Donjon Marine. The company selected a 16 yd³ environmental bucket, manufactured by Cable Arm, to fulfill the contract requirements. This bucket has proven to be quite successful in removal of material to a point "of refusal", an area just at the silt/clay interface.

Other vessels involved are three (3) tugs, a crew boat, and two (2) new 4,000 yd³ ocean dump scows. The dump scows will be used for the disposal of approximately 700,000 yd³ of material from the Elizabeth Channel, within Port Newark, after approximately 300,000 yd³ of silt material is removed and disposed at an upland facility in Bayonne, New Jersey.

Donjon Marine is a multi-faceted marine company, performing salvage, ocean towing, dredging, and construction for nearly 40 years.
