Dredging
Capital dredging
carried out to create a new harbour, berth or
waterway, or to deepen existing facilities in
order to allow larger ships access. Because capital
works usually involve hard material or high-volume
works, the work is usually done using a cutter
suction dredges Capital dredging can also be defined
as, “the removal from beneath water and
rising through water or soil, rock or debris to
create a greater depth than had previously existed”.
