Belgium dredging contractor Dredging International N.V. ordered the replacement-delivery for the original Human Machine Interface (HMI) SCADA presentation system on its jumbo trailing suction hopper dredger Pearl River. The vessel with an excellent track record in operating through-out the World, played an important role in the various capital dredging projects in the Far East and operates currently in China. The vessel, ancestor of the jumbo trailing suction hopper dredgers class was originally built in 1994 at the IHC Holland Merwede yard in Kinderdijk, was enlarged in 2002 and has a hopper capacity of 24.146m3. The Pearl River will receive a nowadays SCADA presentation system which is in concept derived from recent built hopper dredgers among them the Pallieter. Knowledge within both companies DI and IHC Systems, recent presentation experiences and a delicate balance between process-and diagnostic presentation are key figures which led to the current presentation solution. The project started with a detailed verification/specification phase, will comprise an in house application software development for both SCADA and PLC control, a Factory Acceptance Test to enable a smoothly switch-over and the physical implementation on board, which is scheduled for mid 2005.


German dredging contractor Johann Bunte has ordered at IHC Systems the delivery of IHC Systems' new generation eXcavator Position Monitor system (XPM) for its Backhoe dredger JBP63 a Liebherr R964. Bunte acquired the Backhoe dredger fleet by taking over the German onshore activities from Heinrich Hirdes, a Royal Boskalis venture. The present XPM-NG is a result of a long-lasting Backhoe and Dig-viewer dredging instrumentation experience of both IHC Systems and Meconaut. Meconaut, a supplier of dredge instrumentation, was bought by IHC back in the early nineties. Knowledge of excavator presentation and automation within both companies, IHC Systems and Meconaut, led to the present XPM system performance, automation capabilities and presentation features. The new (redesigned) XPM system will have various interfaces to satisfy owners' requirements in information exchange with third parties navigation and survey equipment and DTM (digital terrain model) presentation.

IHC Systems has been awarded an order to supply a 120-150° dynamic outside view to add to the cutter suction dredger simulator for the French daughter SDI of the DEME Group, Belgium. The simulator and its outside view will be developed in co-operation with DEME technical and operational staff. It will be used to educate existing and future crew for the cutter suction dredger fleet. The simulator is intended for SDI in Lambersart near Lille, France. The main purpose is to familiarise the crew with the amount of information, typical dredging characteristics and the necessary actions as a result of trainer initiated disturbances.


The artificial outside view will be created by 3 ea. 1500*2000mm presentation screens set up in a frame to enable a 120-150° view on the foreship, with operating side-and ladder winches, cutter, ladder and land (sea) scape.

Denmark's largest dredging contractor Rohde Nielsen A/S, has granted IHC Systems the order for the delivery of new dredging presentation system for its trailing suction hopper dredger Thor-R. The RN Group was founded by Captain Jens Rohde Nielsen in 1968 and now, over 35 years later, operates world wide from Copenhagen, and specializes in capital and maintenance dredging, land reclamation and coastal defense such as beach nourishment.


The dredger, THOR-R, will be equipped with today' s dredging instrumentation for:

  • Draught and Loading Monitoring system (DLM)
  • Tons Dry Solids Monitoring system (TDS)
  • Production Calculation system (PRC) partly upgrading existing systems partly new delivery
  • Data logging system carrying dredging data according to contractors' requirements for dredging contracts
  • All systems will be delivered including their typical transmitters and will be commissioned in Danish waters

The Jan De Nul Group has ordered for its two stationary cutter suction dredgers, Kaerius and Hondius, two medium sized vessels with a cutter power of 1500 kW, and a total installed diesel engine power of about 8500 kW, and for its De Bougainville 3.700 m3 split barge IHC Systems' production measurement systems. The vessels are being built by Tianjin Xinhe Shipyard in China, will be delivered in the course of 2006.
