Back to overview efficient solutions.
When in the late 1990’s the size of dredgers exploded, the complexity of systems to guide and manage them had to follow suit. IHC Systems' brief was to further develop sensors and instruments on one hand and make the mass of their signals intelligible for dredger masters on the other. That is why IHC Systems developed the concept of the totally Integrated Dredge Control System. On several large scale TSHD's it has been implemented as the fully integrated bridge concept, crowning the comprehensive range of dredging instruments and computer systems that have made jumbotrailers governable.
To achieve maximum efficiency both on large and small works, and to enable the necessary adaptions to be made swiftly and economically this integrated dredge control system has been designed. All relevant data are presented in comprehensive form on video screen(s). Presentation of data and control of all functions, such as: dredging, power management, reporting and communication with survey or navigation equipment takes place at one or more HMI’s. This system controls the various phases of the dredge process, if desired fully automatically.
PLC technology is at the basis of every integrated control system for dredgers. PLC systems have proven to be highly reliable under the severe circumstances on board of dredgers.The PLC system controls and monitors the several dredge functions and provides communication with systems like IHC Systems' STPM, DLM and PRC. The PC based supervisory system communicates with the PLC’s on the one hand. On the other hand it provides the operator with preprocessed information by means of the video screens and gets input from the operator through a keyboard or touch screens.
In order to offer the client a clear insight into the dredging process being performed, IHC Systems has made available a new system which is capable of publishing all relevant data on the Internet in a transparent manner: the Cyber Payment Monitor.
It will be clear that IHC Systems’ approach is to use existing computer technology in designing systems that help operators using their dredger more effectively.
