Dredger Size
From an engineering point of view, a dredger is a vessel designed to remove sediment and debris from the bottom of waterways, ports, and harbors. The size of a dredger can vary depending on its intended use and the specific requirements of the project it is working on.
Length: The length of a dredger can range from 20 meters to over 200 meters, depending on the size of the project and the amount of material that needs to be removed.
Speed: The speed of a dredger is typically slow, ranging from 1 to 5 knots, in order to allow the dredging equipment to effectively remove sediment and debris from the bottom of the waterway.
DWT: The deadweight tonnage (DWT) of a dredger can range from a few hundred tons to over 100,000 tons, depending on the size of the vessel and the amount of material it is capable of carrying.
Number of Active Vessels: The number of active dredgers can vary depending on the size of the project and the amount of material that needs to be removed. Large projects may require multiple dredgers working simultaneously.
Maximum Draft: The maximum draft of a dredger is typically shallow, ranging from 2 to 10 meters, in order to allow the vessel to navigate in shallow waters and effectively remove sediment and debris from the bottom of the waterway.
Cargo Capacity: The cargo capacity of a dredger can range from a few hundred cubic meters to over 50,000 cubic meters, depending on the size of the vessel and the amount of material it is capable of carrying.
Some of the main shipyards and countries for the building process of dredgers include:
- China: Shanghai Zhenhua Heavy Industries Company, Shanghai Shipyard Company, and Dalian Shipbuilding Industry Company
- Netherlands: Royal IHC, Damen Shipyards Group, and Boskalis
- Belgium: Jan De Nul Group and DEME Group
- Japan: IHI Corporation and Mitsubishi Heavy Industries
