Tugs and Tows

Tugs and tows are used for moving non-propelled dredging equipment over long and short distances for a variety of purposes.

Trailing Suction Hopper Dredgers

Trailing suction hopper dredgers or “trailers”, are self-propelled ships with hoppers, which are storage areas in the hull for keeping dredged material.

Suction Dredgers

Plain suction dredgers are stationary dredgers positioned with wires and with at least one dredge pump connected to a suction pipe and a delivery pipe.

Side Stone-Dumping Vessels

Side stone-dumping vessels are used for transporting and placing rock and boulders in maritime and fluvial locations.

Split-Hull Hopper Dredgers

Split-hull hopper dredgers discharge their loads from underneath the vessel by opening up – splitting – their hulls.

Ploughs, Beams and Rakes

Ploughs, beams and rakes are tools that are attached to an A-frame, mounted on the stern of a tug or work boat and dragged across the waterbed.

Pontoons

Pontoons are floating platforms that can be adapted to function in a multitude of ways during dredging operations.

Pipelines

Pipelines fall into three main categories: floating pipelines, submerged or “sinker” lines and land or “shore” lines.
