Capital 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”.

Maintenance Dredging

Maintenance dredging to deepen or maintain navigable waterways or channels which are threatened to become silted with the passage of time, due to sedimented sand and mud, possibly making them too shallow for navigation. This is often carried out with a cutter suction hopper dredge. Most dredging is for this purpose.
