Grab Dredger

A Grab Dredger is a specialized vessel used in underwater excavation, equipped with a large, powerful crane-like arm called a grab. This arm scoops up sediments, mud, or debris from the bottom of water bodies like rivers, harbors, or seas. The collected material is then transferred to a nearby barge or location for disposal or land reclamation. Grab dredgers are essential for maintaining navigable waterways, creating new land, and removing accumulated sediments that hinder boat movement or infrastructure development. They operate efficiently in various water depths, making them versatile tools in dredging projects.
