The idler barge can be connected as well to the under-construction state of the art 27-inch cutter suction dredger.
#DREDGE BARGE UPGRADE#
The idler barge is the first upgrade and innovating of Mike Hooks current fleet. All the movements are hydraulicly driven, the spud can be fully controlled from the lever room and is a one-man operation. The idler barge is set to increase the production with approximately 25% compare to the fixed spud system. The idler barge, fabricated at SWSLP Shipyard in Galveston and equipped with SPI Mobile Pulley Works spud installation, will be connected to the cutter suction dredger (CSD) Missouri H., and will be starting operation in Gulfport, Mississippi, in the following weeks. Dredging is often limited by other factors such as dewatering or disposal, so costs can be affected by the entire process as well.SPI/Mobile Pulley Works has delivered a brand-new Idler Barge to Mike Hooks LLC. All of these factors is why dredging cost range from a $3 to $300 per cubic yard. Dredges are unique in that break-downs and maintenance usually have to occur on the water so adequate support personnel and equipment must be available. Remediation – clean-up of the project site and installation of best management practicesĬosts to operate the dredge include wear parts, labor, fuel, and maintenance.
Disposal – the setup of the disposal area and final reclamation or the tip-fee for a landfill.
months) and distance to the disposal area Export and Transport – the time for the dewatering (immediate vs.Run-times – 24/7 or 5 days for 8 hours weather is also a major factor depending on the project.Type of Sediment – texture of the sediment determines the type of dredge and dewatering process debris can add to cost significantly.shallow sediment depth takes much more time to dredge) Depth of Sediment – water and sediment depth determine much of the cost involved (i.e.Mobilization – both of the equipment, the setup for dewatering, and disposal site.Planning – designing engineered plans usually for the dewatering area and disposal.Permitting – local, state, and federal are considered in most projects.Cost involved for dredging projects are typically as follows: In addition to the actual work, some other considerations must be made including safety protocols, risk management, permitting requirements, and future maintenance.ĭredging is highly variable in cost. too wet to dig or too many rocks to pump). Pumping versus excavation may be a consideration based on the sediment type (i.e. Dredging methods can vary with different equipment types and options. Sampling sludge is another great tool that can be implemented in the process. Pre and post construction surveys are a great example of an idea that can help confirm a project’s results. The unusual aspect of working under water and with water involves many challenges. From design-build services, pre and post dredge surveying, specification writing, and financial considerations River Sand can help you with the details.
Contracts, requests for proposals (RFP), solicitations, and bids can involve tedious details to make sure the client is satisfied with the result. We also work directly with owners to do the same. River Sand has a long history of working with engineers to develop a plan for dredging projects. One of the first steps in analyzing the need to dredge your lake may be to determine depth, location, and volume of sediment with a bathymetric or sediment survey. However, in most cases dredging is an effective solution to the problems listed above and many others. Sometimes dredging costs can outweigh the benefits of performing the work, deeming it unfeasible to dredge from a cost-benfit perspective. For example, very dirty water with a red color may contain high turbidity (suspended solids) but may not mean that there is enough sediment. River Sand can help confirm that dredging may be the correct solution for the problem.
