Dreging on the open sea

A trailing suction hopper dredger (TSHD) is a type of dredging vessel that is commonly used for maintaining and deepening waterways, ports, and other water bodies. The TSHD is equipped with a large suction pipe, which is lowered to the seabed or riverbed to suck up sediment and debris. The material is then transported through the suction pipe and stored in the vessel's hopper, a large storage space located in the vessel's hull. The hopper can be filled with large amounts of sediment and debris, depending on the vessel's size, and can be emptied by opening the vessel's bottom doors.

TSHDs are typically equipped with powerful engines and propellers to allow them to navigate through shallow waters and to transport their loads to disposal sites. The dredging process is highly automated, and modern TSHDs can be controlled remotely using advanced computer systems. TSHDs play an important role in maintaining navigation channels and harbors, which are critical for global trade and commerce. They are also used for coastal protection, land reclamation, and environmental dredging to remove contaminated sediment.
