![]() ![]() To avoid dredging accidents, vessel owners and crews need to ensure: Equipment risks aboard hydraulic dredges include injuries from high-pressure water jets and powerful suction and vacuum tubes.Įven though they may be working in a river, lake or shallow inlet, dredgers must be as seaworthy as any other vessel.Being hit by a crane or getting caught in a bucket can lead to serious injuries aboard a mechanical dredge.The cranes, buckets, hydraulic pumps and other large, powerful heavy equipment employed to dredge up the sediment present their own hazards as well. Mechanical dredges do the job by “hand-packing.” This involves using a crane and bucket to reach down and scoop up the material and then deposit it for disposal. There are two main types of dredgers: mechanical and hydraulic. However, in many situations it is the only option for keeping a waterway open to traffic. Dredging accidents also can lead to serious worker injuries. In addition, dredges can be used to replenish beach sands that have undergone extensive erosion, mining and excavation projects, creating new harbors and containing environmental pollution.ĭredging is often controversial because of the harmful effects it has on the marine environment. Without regular dredging, many of America’s naturally shallow waterways would be inaccessible to large oceangoing vessels. This is important to keeping a waterway safe for navigation. Dredgers are used to remove sediments and debris from the bottom of lakes, rivers, harbors, and other bodies of water. Dredging vessels, or dredgers, play a vital role in today’s maritime industry. ![]()
