Industry & Occupation
Classification
Summary
Specialist who operates dredging machines to improve the bottom quality of rivers, ports, and canals, and remove sediment.
Description
Dredging machine operators handle construction machinery such as dredgers and land-installed pump-type dredging machines to perform bottom sediment improvement and sediment removal work in rivers, ports, and canals. Based on construction plans, they operate the machines while measuring excavation depths, handling the entire process of sucking up sediment and sending it to lifting and discharging equipment. Important tasks also include machinery maintenance inspections, safety management of work environments, and compliance with laws and regulations. Since site conditions and sea states are constantly changing, skills in operating surveying equipment, reading construction plans, and teamwork are required. Additionally, the ability to consider construction methods that reduce environmental impact and adapt to sustainable civil engineering projects is necessary.
Future Outlook
Demand for dredging remains stable due to river and port redevelopment and foundation work for renewable energy facilities. Shortage of skilled operators is an issue, and acquiring environmentally friendly construction techniques and machinery automation skills is expected to increase future market value.
