Industry & Occupation
Classification
Summary
Dredgers are ship operation jobs that excavate the bottom sediment of ports, rivers, and waterways, removing soil and deposits to ensure and maintain water depth.
Description
Crew members of dredgers operate dredging equipment such as excavators and suction pumps to transfer sediment accumulated on the seabed or riverbed to onboard storage hoppers or land facilities. In addition to maintenance management of waterways, ports, and rivers, they also engage in marine civil engineering projects such as reclamation and land development. A wide range of duties are included, such as navigation operations, equipment inspection and maintenance, monitoring sea conditions and currents, and sediment volume calculations.
Future Outlook
Stable job openings are expected due to the maintenance of ports and rivers and demand for land development. With the introduction of automation and remote operation technologies, the sophistication of operation and equipment handling will advance, so the demand for specialized technicians is expected to continue.
