Cutter suction dredgers are hydraulic dredgers that uses Cutter suction dredgers may: 1. have a pontoon hull without a means of propulsion (nonpropelled), or 2. be selfpropelled, seagoing specially designed vessels. Whether selfpropelled or not, the cutter will be moored with spuds or anchors while at work so that in essence the dredging operation takes place with the cutter in a stationary position. Se

dredge nearly all kinds of soils, especially hard ground and rock. cutter suction dredgers (csds) are classified as hydraulic dredgers and are the most common vessels in the hydraulic/mechanical category. dredge pumps at best price in indiavosta lmg#39;s dredge pump systems are always highly efficient, even after extensive use. due to their excellent, stable suction performance, long wear life and a minimum of maintenance, the systems are able to handle bigger volumes in less time and at a lower cost. the pumps are optimised by cfd (computer fluid dynamics) to get built expressions bangalore :: deep and shallow water marine today trailing suction dredgers of 30,000 m3 capacity capable of dredging up to a depth of 35m and possessing a laden speed of 17 knots are in use. cutter suction dredger cutter suction dredgers (fig.7) are versatile and can deal with a wide variety of materials including clay, silt, sand, gravel and some grades of rock. cutter suction dredgers are hydraulic dredgers that uses cutter suction dredgers may: 1. have a pontoon hull without a means of propulsion (nonpropelled), or 2. be selfpropelled, seagoing specially designed vessels. whether selfpropelled or not, the cutter will be moored with spuds or anchors while at work so that in essence the dredging operation takes place with the cutter in a stationary position. see full list on iadcdredging the cutter suction dredger is equipped with a cutting device known as a cutter head. the cutter head is a mechanical rotating tool, which is able to cut hard soil or rock into fragments. it is mounted in front of the suction head and rotates along the axis of the suction pipe. this rotation disaggregates, i.e., separates, and excavates the soil which is then drawn into the suction pipe as a solid/water slurry and pumped to the surface. different cutter heads are designed for specific types of soil, because hard soil, noncohesive or cohesive soils have different requirements. dredging in hard soils will cause wear and tear so that cutter teeth need to be replaced regularly. see full list on iadcdredging during operation the dredger moves around a spud pole by pulling and slacking on the two fore sideline wires. at the same time they cut with an accurate profile because of their movement around the spud. the spud stays in the same spot allowing the dredger to make concentric circles during swinging. see full list on iadcdredging the material dredged by a cutter is usually transported hydraulically through a pipeline, although some cutters have bargeloading facilities as well. the pumps produce the flow required to lift the disaggregated material from the bed and then to transport a watersoil slurry through a pipeline from the dredger to a discharge point. by use of booster pumpsin the discharge lines, they can transport and place materials at considerable distances from the work site. see full list on iadcdredging the most powerful cutters can dredge hard rock effectively on a continuous basis. the selfpropelled csds can travel long distances and be deployed in remote locations, far from their home port, making them flexible to be used all over the world. they can work in shallow waters and they also have flexible discharge alternatives. small and medium size cutter suction dredgers can be dismountable and transportable over land. the hull is then comprised of a series of pontoons, with the one pontoon containing the machinery. see full list on iadcdredging cutters are powerful and are capable of dredging all kinds of material including hard rock. they are able to effectively dredge: 1. silts, 2. clays, 3. sand, 4. gravel, 5. cobbles, 6. fractured rocks 7. and sound (unfractured) rocks. see full list on iadcdredging cutter suction dredgers characteristically have high production rates and the ability to effectively handle a wide range of materials. the production capacity designed is, of course, directly related to the hardness of the material that the cutter is going to dredge. see full list on iadcdredging cutter suction dredgers are used wherever the seabed is hard rock. they are used for larger dredging projects such as navigation channels and port development and maintenance and land reclamation and in major projects such as the panama canal and the suez canal. see full list on iadcdredging source china
