Industry & Occupation
Classification
Summary
A job that operates and controls suction dredgers (dredging vessels) to suction and remove sediment and deposits from the seabed or riverbed.
Description
Suction dredger operators work from the control seat or room of dredging vessels, navigating the ship while operating dredging pumps and suction pipes to remove sediment from the seabed or riverbed. They adjust excavation depth and route based on construction plans, using GNSS and echo sounders to monitor position and depth in real time. They also handle equipment inspections, maintenance, fuel management, and safety monitoring. They must respond to changes in weather and currents or equipment malfunctions while coordinating closely with crew members and onshore site supervisors.
Future Outlook
Demand for port and river dredging is ongoing and stable from the perspective of population decline and infrastructure aging countermeasures. Strengthening environmental regulations and the introduction of unmanned and automation technologies will increase the importance of not only machine operation but also data analysis and remote control skills.
