About dredge operator

What a dredge operator does is control the machine and know what is beneath it. The operator positions the dredger over the area to be worked, measures the depth of the water before and during the cut, and takes samples of the material being removed so that what is coming up is known. Removed material is transferred to the place it is wanted, which may be a disposal site, a reclamation area or a barge. Because the bottom cannot be seen directly, the readings and the samples are what the operator works from, and reading them correctly is the substance of the job.

The dredging equipment is maintained by the operator, who keeps the mechanical systems in working order and carries out the servicing a machine working in water and sand constantly needs.

A dredger driver has to avoid damage to public utilities, since cables and pipelines cross the water as well as the land, and follows the health and safety procedures of the construction sector. Working ergonomically matters across a long shift at the controls. Requirements for the post, including any certificate for the plant operated, are set by the employer and by national rules.
