description

Dredging vessels are designed for excavation activities. These are usually carried out underwater, in shallow or freshwater areas, with the purpose of gathering bottom sediments and disposing of them at a different location, mostly to keep waterways navigable. for port extensions, or for land reclamation.

Maximum efficiency and minimum labor costs are essential for the successful operation of dredgers. RELONG’s products and solutions are designed to match this requirement and are based on industrial state-of-the-art hardware components.

The control and monitoring system for cutter dredgers consists of decentralized process interfaces and centralized controlling units. The PLC and the remote I/O components are connected via a field bus network. The system combines all the monitoring and control functions required for the complete dredging installation by means of different, task-oriented mimic diagrams.

The flexible design configuration enables the best possible usability in line with the customer’s particular requirements. All needed information is available at the dredge master’s desk. This set-up typically includes an Automatic Cutter Control system for cutter head and cutter wheel dredgers. The system acquires and processes all data necessary for automatic dredging processes. All signals and computed values are available for multi-display presentation. Profile data, feed values, and alarm limits are entered via the control computers, which also allows the selection of different operational modes.
