Abstract: We are using more and more efficient dredging technology, applying advanced designs, dredging components and integrated systems. This allows dredging operations with high efficiency for projects at high accuracy while operating in more difficult soils and site constraints. The use of advanced automation and control systems enables efficient and sustainable use of the innovative dredging equipment in these circumstances, but final performance is still determined by the operational crewand project staff organization. Without a high level of crew and staff competence – best described as a combination of proper dredging knowledge, skills and experience – it will be difficult to take advantage of the available modern dredging technology.
Current competence improvement is based more and more on specific training and educational programs using modern means like dredge simulators. Use of simulators allows practical training without production losses. Furthermore, the right combination of practical simulator training and learning theoretical background will not only teach a trainee the dredging trick. But also why it should be applied and to be self supporting within the ever more complicated dredge jobs, due to ever more required accountability, also due to environmental rules.
In modern dredge simulators for excavators, cutter suction and hopper dredgers, all related dredging processes including sensors, actuators and the dynamic relationship between the processes are simulated to obtain a realistic virtual dredge operation. The virtual dredge can be controlled using real control means installed in commercial type of consoles. Depending on the execution of such a console, trainees can also be trained on the use of automation systems and on-board diagnostics and data logging. Use of the latest state of computer technology, central monitoring and data logging allows a three dimensional virtual view of the outside world. Not only what is normally seen from the control room or bridge, but if required also as an underwater view.
Adding monitoring systems, as used in practice, to the dredge simulator like an eXcavator Position Monitor (XPM), Dredge Profile Monitor (DPM) or Dredge Track Presentation System (DTPS) enables training programs on the use of these systems.
And several surrounding issues like positioning, dredge job preparation and progress and operational enhancement. In this paper the latest state of the art dredge simulators and their possibilities in training programs for excavators, cutter and hopper dredgers are described. Emphasis is given on howthis improves the operational competence of dredger crews and dredging company staff members for efficient and sustainable use of modern equipment.
