Italdraghe SGT 400 E · Eco-Green Dredger

EV Dredger

Electric cutter suction dredging, powered from shore. The SGT 400 E brings a 500 kW dredging pump and a 75 kW cutter together in a modular dredger for project-specific deployment.

01 / Power & control

Built around an electric system.

Shore power supplies the onboard electrical system. Confirm the site connection and supply capacity before specifying the dredger.

01

Power from shore

The onboard dry-type transformer connects the dredger to its onshore electrical supply, providing power for the electric dredging and working equipment.

02

Adjustable electric drive

Inverters control starting and adjustment of the dredging pump drive and the cutter motor. The 500 kW and 75 kW ratings describe these two systems individually.

03

Electric working equipment

Electric winches control the swing motion, raise the ladder and move the two spuds. The manufacturer describes operation by one person from the control cabin.

Site electrical design must account for the complete installed load, auxiliaries and operating conditions; the pump and cutter ratings alone do not define the required shore connection.

Arrangement shown in the manufacturer’s SGT 400 E datasheet. Final configuration is project-specific.

02 / Modular construction

Designed to reach the project.

The dredger can be dismantled for transport by road, rail or sea, then assembled at the work site. Its layout combines the pump installation, control cabin, cutter ladder and spud equipment on a transportable platform.

Plan the access route, lifting arrangements, assembly area and shore power supply together. Confirm transport dimensions and component weights with the manufacturer for the selected configuration.

05 / Optional equipment

Configure for the dredging project.

Availability and suitability must be confirmed for the final scope. Optional items are not implied to be included in the standard specifications.

01

Positioning & working reach

Options include a spud carriage, anchor booms with enlarged side pontoons, positioning equipment and increased dredging depth.

02

Discharge & production

Discuss pipeline length and diameter, discharge equipment, booster pumps and production measurement as part of the complete dredging system.

03

Operator environment & support

Cabin damping, air conditioning and on-site operator training are listed options. Supporting pipelines and workboats can also be discussed with the manufacturer.

06 / Source documentation

Review the manufacturer’s data.

Product photographs, arrangement and specifications are based on the supplied Italdraghe SGT 400 E datasheet.

Technical data are manufacturer guidelines and may change. Confirm the final configuration, electrical interface and guaranteed duty point directly for your project before ordering.
