Engineering

Een goed ontwerp is niet alleen het product zelf, maar het resultaat voor de integratie met zijn omgeving. Onze engineers ontwerpen een innovatief product met moderne technieken voor de hoogste efficiëntie. Aan het begin van het ontwerp is het verstandig om de doelstellingen en eisen te verzamelen en vast te leggen. Door stap voor stap door het ontwerpproces te gaan is het mogelijk om kostbare fouten, verspilling van tijd en demotivatie te voorkomen. Alle onze baggerschepen zijn modulair ontworpen terwijl de werking en de veiligheid op het water zijn gegarandeerd. Het voordeel van dit modulaire ontwerp is dat alle onderdelen vervoerbare modules zijn en alle modules kunnen worden aangepast naar de voor u optimale prestaties.

Basic Engineering

 

Construction Package

 

Production Package

         

Met het gebruik van het nieuwste engineering programma zal de machine in 3D worden gecreëerd en getest.

We doen een intake door informatie te verzamelen van de benodigde eisen en kijken naar de mogelijkheden. Dit zal resulteren in een document met technische specificaties en een general arrangement (GA). Om deze Basic Engineering te creëren, leveren wij:

  • dredger General Drawing
  • pontoon size drawing
  • pump calculations
  • power source calculations,
  • pre-hydraulic stability on water
  • winch calculations
  • pre-structural calculations
  • excluding the design changed from the original situation
 

De volgende stap na het basisontwerp is het construeren van de materiaalspecificatie en de positie van de onderdelen. Deze Construction Package bestaat uit:

  • pontoon assembly drawings and bill of materials
  • cabin assembly drawings and bill of materials
  • suction pipe and/or ladder assembly drawings and bill of materials
  • hoist construction assembly drawings and bill of materials
  • structural construction assembly drawings and bill of materials
  • railing and stairs assembly drawings and bill of materials
  • technical specifications of components
  • electric / hydraulic schedule
  • final hydraulic stability on water report
  • final structural calculations report
  • excluding the design changed from the original situation
 

Na het constructie design moeten de onderdelen worden geproduceerd. De onderdelen die we gebruiken om de dredger te bouwen zijn normale staalplaten en standaard balken of profielen. Deze onderdelen moeten op de juiste manier worden gevormd om zonder problemen te gebruiken in de assemblies. Voor de productie van deze onderdelen is een productiepakket aan te bevelen. Dit Production Package bestaat uit:

  • part drawings (individual)
  • cutting drawings (files to cut steel sheets)
  • basic (purchase) component drawings
  • fasteners list and drawing
  • welding specifications
  • conservation specification
  • user manual
  • part book and
  • risk analysis (CE)
  • excluding the design changed from the original situation

The Dutch Dredgers cutter dredgers are used for sand mining purposes. The cutter dredger has a welded engineroom as body and this body is built above or under water table. Above the engine room is the control room situated.

The movement of the cutter head is up and down and from left to right which is accomplished by cylinders. In this manner the cutter unit has the possibility to sweep instead of moving the complete dredger.

On both sides are 2 square floaters. These cutter dredgers can be equipped with an electric or hydraulic cutterhead which has cutting knives or teeth installed. This dredger is easy to transport by containers.

 

The Multifunctional Dredger with both WATER JET and CUTTER function can be used in soft and hard lay-ers for the cleaning of rivers, ponds and sand mining purposes. One dredger for all types of soil. The main ad-vantage is the submersible dredge pump which is located on the dredge pipe to generate the highest efficiency. Another advantage of this dredger is the possibility of changing the dredge system during work. This changing can be done easily with the cranes which are mounted on both sides of the dredger. Also the anchors and spare parts can be lifted by this crane, guaranteeing an ergonomic working. The dredger is built compact so the cost are low and the construction is designed to make transport by sea freight containers possible.

 

The Compact cutter dredger is a self-maneuvering demountable dredger that is suitable for canals, water-ways, rivers, harbours maintenance and for sand mining purposes.

The suction pipe can swing and lowered hydraulically and has standard a cutter head and optional a water jet sys-tem. Because of the special design this dredger can be (dis-)assembled and transported very easy in shipping containers or on trucks. Standard there are 2 walking spuds on the bow of the dredger. At the stern there is standard a winch and optional the possibility for a spud carrier. The spuds can be tilted and the cabin top can be removed to get a low strike height above the water level to pass bridges.

The Dutch Water Jet Dredgers with a waterjet system and submersible or dry Dregde Pump can be used  in soft and middle hard for the mining of sand and gravel pits. Dredge depths are in the range of 5 till 80 meters.

By using the submersible dredge pump, the concentration is higher and dredge depth is deeper, this creates high efficiency.

So this Water Jet Dredger is the  perfect machine to dredge in an mining pit with electric power.

 

The Dutch Dredgers Pontoon Solutions with waterjet, cutter or auger function can be used in soft and hard layers for the cleaning of rivers and ponds. 

The main advantage is the submersible dredge pump which is located on the excavator to generate the highest efficiency. Another advantage of this excavator solution is the possibility for the changing of the dredge system during work.

So this Pontoon Solution is the perfect machine to dredge in an environment with a changing soil.

 

The Dutch Dredgers Barge Solutions with both waterjet and cutter function can be used  in soft and hard layers for the cleaning of rivers and ponds. 

The main advantage is the submersible dredge pump which is located on the excavator to generate the highest efficiency. Another advantage of this excavator solution is the possibility for the changing of the dredge system during work.

So this Barge Solution is the  perfect machine to dredge in an environment with a changing soil.
