Monitoring system (CSD

The system presents important operational cutter suction dredger parameters, such as suction depth and position of the cutterhead/suction inlet in the dredge profile. It also provides optional presentation of estimated anchor positions to assist with decision-making.

• Enables accurate dredging according to authority requirements
• Highly accurate, reliable and fuel efficient
• User-friendly touchscreen control
• Signal provision for automatic and semi-automatic profile dredging

Applications and main features

• Real-time, accurate ‘dressed wire model’ of dredger in multiple point-programmable, local grid-oriented dredge profile that is updated online.
• Provides insight in under/over dredging.
• Local grid can be enhanced to geographical DTM if survey data is uploaded.
• Chart-datum referred dredging depth, spud carrier and draught presentation included.
• Manual or optional automatic tidal reference input.
• Outputs for automatic profile dredging (to be realised by optional PLC module).
• IHC knowledge-based software platform Digisys.
• Sensor I/O handling by proven PLC-SCADA-Ethernet technology.
• Can be delivered from standalone up to fully integrated (DCS-part) versions.
• Highly accurate with a large installed base.
• Suitable for remote software maintenance and upgrades.

Operational efficiency-enhancing presentation options based on DPM®

Based on winch wire paid-out length measurements and model-based processing, the Anchor Position Estimator (APE) supports the operator by presenting the positions of the swing winch anchors. Features include the following:

• anchor positions related to dredger and bottom profile
• advice on anchoring area in view of effective holding force for optimal production
• alarm on improper anchor dragging.

The DPM can also be applied as an input device in combination with the Automatic Cutter Controller (IHC ACC®) for fully automatic CSD control.
