Effects of dredging on subtidal macrobenthic community structure in Mejillones Bay, Chile
The construction of Port Angamos terminal 1 in Mejillones Bay, Chile, required the dredging of 1,200,000 m³ of sediment from depths of 2?20 m. The effects of dredging on macrobenthic faunal communities are due to chemical (organic material) and physical (granulometric) alterations of the environment and are variable depending on the specific conditions of the intervened area. This study uses ...

Dredging in Icing Conditions under a Narrow Timeframe Challenges Man and Machine - Alberta, Canada - Case Study
Inner City Diesel LTD successfully dredged 30,000 cubic meters of materials in extreme cold conditions, pushing people and equipment to higher levels of performance. Their customer was under a short timeline and government restriction to clean up two closed coal mine lagoons. Working against freezing temperatures and a short clock created a project with no margin for error. Their decisions ...

Environmental Impacts of Dredging on Seagrass Habitats – Part 2
A worldwide study showed in 45 cases, a total loss of 21,023 hectare (or general surface area) of seagrass due to dredging. Seagrass serves as an ecosystem, a food, and a home to many high risk marine species. Dredging, maritime activities, and various enterprises of man contribute to the death of aquatic ecosystems every day. The interesting thing about dredging is that it’s actually ...

Clay Lumps under Simulated Hydraulic Transport Conditions
Laboratory experiments with compacted kaolinite-bentonite mixtures indicate that degradation of hydraulically transported clay lumps in a dredge pipeline can be predicted and controlled to some extent. The size reduction of these lumps depends not only on the length of the pipeline but also on the density of the clay being dredged, the plasticity index (PI) of the clay, and the velocity of the ...

Characterising dredgeability of aggregate deposits for clamshell dredge
The lack of metrics to assess clamshell formation dredgeability limits the ability of engineers to predict the dredgeability of compact material and increases the risks associated with clamshell selection. Work done and motor energy are possible dredgeability metrics that can be estimated using micro–processor based machine monitoring. The objective of this work was to test the hypotheses that ...

SRS Crisafulli`s Laura Fleming asks
An afternoon sitting at the Dulles International Airport, after a 6:00 am Delta flight out of Billings, MT allowed me to indulge in one of my favorite things. I purchased four books. And then, two days later, as part of a Saturday afternoon excursion with my 23 year old daughter, we stopped at Barnes & Noble in Danbury, CT and I purchased six more books. Yes, we are engaged. Of my new ...

Two stainless steel rotomite applications - dredging caustic and abrasive materials in South Korea and Venezuela
Customer: Zinc mining & processing facility, South Korea. Problem: How to remove 200,000m3 of 325 mesh goethite (pH 2.2 - 2.5 range; sulfuric acid) from a lined pond with dimensions of 120m x 253m. Since the material had settled and was resting on the pond bottom, dredging was selected as the appropriate removal method. No standard acid-resistant dredge was in production which would enable ...
