China’s first dual-fuel powered trailing suction hopper dredger, the “XIN HAI XUN” has successfully completed its sea trial in July. With a liquefied natural gas (LNG) clean energy capacity of 15,000 cubic meters, the vessel boasts a total length of 155.7 meters, a breadth of 32m, a depth of 13.5m a
In the heart of Superior, Wisconsin, lies Pickle Pond—a nine-acre urban waterbody that once bore the burden of pollution and neglect. White Lake Dock & Dredge, a division of ENTACT, recently transformed this pond into a prime example for environmental restoration and community revitalization. Spearh
Earlier this year, Rohde Nielsen partnered with SEAM for the hybridization of two dredging vessels. These projects, which represent a new segment for SEAM, aim to reduce emissions and increase efficiency in Rohde-Nielsen’s dredging operations. Rohde-Nielsen has a long history of implementing measure
J.F. Brennan Company recently embarked on a vital restoration project for the middle section of the Lake George Canal. The primary goal was to protect aquatic organisms by separating them from contaminated sediment through a multi-layer sediment cap. The project, executed by Brennan and USACE on beh
Protecting coastal areas and islands against rising sea levels and the forces of waves requires big equipment and major work. But before interfering in an existing ecosystem, people naturally want to know whether the measures they have devised will hold up in practice. With that in mind, Boskalis re
The U.S. Army Corps of Engineers, St. Louis District’s Dredge Potter is currently working near Grafton, Illinois, between river miles 218 and 222, using a 300-foot-long flexible floating pipeline to remove material from the navigation channel. The flexible pipeline allows for the creation of ephemer
Rijkswaterstaat and the Port of Rotterdam Authority are working hard to ensure an accessible port and the hinterland. To maintain the water depth in the waterways, they dredge and maintain the port basins and navigation channel in the Nieuwe Waterweg. In doing so, Rijkswaterstaat and the Port of Rot
The Central Dredging Association (CEDA) has released new information paper on Environmental Adaptive Management. CEDA – committed to promoting concepts for sustainable dredging and waterborne construction works – supports the concept of Adaptive Management within dredging projects. Adaptive Manageme
The U.S. Army Corps of Engineers, Rock Island District has successfully completed the first Navigation and Ecosystem Sustainability Program (NESP) construction project well ahead of schedule. The Starved Rock Breakwater project broke ground in February and is a habitat restoration effort designed to
The U.S. Environmental Protection Agency has announced the start of a $84 million Great Lakes cleanup project in Rouge River near Detroit. Sediments in the Lower Rouge River Old Channel are contaminated with polynuclear aromatic hydrocarbons, or PAHs, heavy metals, and polychlorinated biphenyls, or
The Port of Seville improves navigation, and at the same time promotes biodiversity in the Guadalquivir estuary. Each year, part of the sand extracted from the maintenance dredging of the canal is reused for the creation and conservation of wetlands for aquatic birds. These habitats, designed togeth
Royal IHC has been working hard lately on sustainable propulsion systems and things such as electrification of dredging equipment. Fridus Rijnten, Dredging Equipment Director at IHC, is positive when it comes to sustainable business practices: “We are making our dredging equipment parts more and mor
Van Oord and Van Aalsburg have signed a collaboration agreement to further develop circular fascine mattresses. Fascine mattresses are mats of twisted willow that play an important role in maintaining embankment stability, preventing land degradation and protecting waterways from erosion. At present
J.F. Brennan Company recently posted an interesting blog post on Treatability: An Important Asset in Environmental Dredging. Treatability testing uses bench-scale demonstrations and analysis to determine if a material can be effectively treated with a specific chemical or process. At Brennan, they u
