The Different Types of Dredging Equipment

There are several types of dredging equipment, but there are four main ones: mechanical, hydraulic, and backhoe. Let’s discuss each type. In addition to dredges, auxiliary equipment used in dredging operations includes drill boats and dynamite. Sometimes, the additional equipment can be a single dredger or a combination of dredges.

Backhoe dredgers

While backhoe dredgers can dig material from various locations, their performance varies. Backhoe dredgers generally use diesel engines and feature a rotating house. Hydraulics allows the boom arm to support heavy loads. The operator sits in a cockpit mounted on the house and controls the boom arm and house position. These backhoes are usually a permanent fixture in dredging sites.

The names of backhoe dredgers come from Norse mythology. Magnor, for example, means ‘The Fighter’ and has a total installed power of 4,100 kW. The Magnor dredger specializes in challenging ground dredging and has a bucket with a capacity of 67,000 kilograms. Backhoe dredgers have historically been used to dredge landfalls, but they are also increasingly used for environmental reasons.

Hydraulic dredgers

There are two main types of hydraulic dredgers. The first type is stationary. It mines sand by pushing a suction pipe into the sand deposit. The sand is then transported via pipeline to a reclamation area and loaded onto barges. Hydraulic dredgers are also referred to as suction dredgers. Their primary uses are for reclamation work and win fill.

Hydraulic dredgers are highly effective and are the preferred method for dredging. They prevent the dispersion of contaminated sediments into the surrounding water body. However, they are characterized by limited versatility and are best suited to move loose sands. However, they are not suitable for dredging rocks. This may make them less desirable.

Self-propelled dredgers are another popular type. This dredging vessel follows a pre-set track and fills a hopper with sand and other materials. When they are finished, they open the buckets on a long line and bring the loaded material ashore. These dredgers are usually used in open waters. They can move massive amounts of material at high speeds.

Cutter suction dredgers

There are various kinds of dredging equipment. One type is the clamshell dredger, which works by grabbing bivalve sediments and carrying them out of the water. They have a crane and hydraulic cylinders that operate the machine. Another type is the small dredger, operated remotely from a computer. These are used extensively in port facilities and environmentally sensitive projects.

There are two basic cutter suction dredgers: the bucket wheel and the cutter head. Both are used for different types of dredging operations. For example, one type is used for dredging in the seabed, while the other is designed for dredging hard rock sediments. The latter is often used for large dredging projects like maintaining a navigation channel, port development, and land reclamation.

Trailing suction hopper dredgers are self-propelled vessels with a hull in the shape of a conventional ship. They are highly seaworthy and have two or more trailing suction pipes. In addition, they have a high-volume hopper, which can hold hundreds of cubic meters of material. Trailing suction hopper dredgers can dredge hard rock, but they are less effective on stiff clay.

Mechanical dredgers

Dredgers are mechanical equipment used for digging in the water and other bodies of water. The production rate varies according to the type of material to be dredged, the transport and disposal methods, and other factors. There are several types of dredgers, and the choice of one will ultimately depend on the project. Every kind of dredger has its advantages and disadvantages.

A mechanical dredging market study will incorporate extensive primary and secondary research. Primary research aims to gather facts and data for estimating the market size. Secondary analysis will refine this data to derive the market value, growth rate, and forecast. Various methodologies and approaches have been employed to derive these figures. The research team collects data and facts from different regions to give a regional outlook. The report also identifies key players in the market.
