Dredger Conversion and Upgrade

Photo: Dredge Yard

Dredge Yard, a company specialized in dredging and mining components, equipment and technologies, shares insight  into the upgrading of equipment, modification of dredging system and conversion of existing vessels into dredgers.    Upgrading existing dredger systems is quite practical as it offers reusability and functionality of the old dredger with low investment. Converting an existing vessel into dredger can help in increasing the capacity and capability of the dredging companies in much lesser time with a huge saving in investment.   Dredger modifications are also needed when the dredger supplied may not meet the requirements and slight changes in the parts or systems to make it appropriate for the project requirements.   All types of dredgers can be subject for modifications, varying from replacing a single pump with more efficiency, to the whole suction/discharge system of the dredger, or converting existing barges and vessels into dredgers.   Upgrading dredge pumps  A dredge pump or sand-slurry pump is considered the heart of the dredger and plays the most vital role in the dredger’s efficiency.    Dredge Yard’s senior design engineer , Manish Jangir, said, “Latest tools in the market like CFD and optimum design calculating software have widen the paths of having an efficient pump design for the same old pump without changing any fitting parameters or the connections like the flange.”
