Hopper dredger equipment renewal
Dredging is about transporting a mixture of silt, sand and gravel. Together these abrasive materials have a huge impact on the dredging systems on board. All dredging components in contact with this dredged mixture are subject to constant wear and tear. As a result, they need replacement.
Practical exchange of dredging components
A hopper dredger, as any dredger, needs continuous maintenance. Dredging activities result in a gradual yet constant degradation of all dredging gear in contact with the abrasive dredged mixture. As a result, dredging components are replaced often. Damen has a complete range of dredging components available for component replacement.
For all hopper dredgers, great and small

Replacing dredging components
To ensure the reliability of a hopper dredgers operation, maintenance activities are vital. These will result in the exchange of hopper dredger loading gear such as dredge valves, overflows, jet water monitors, jet nozzles and much more.
Telescopic overflows are installed to ensure transport water is removed from the hopper hold efficiently. After years of service, they may need replacement. Damen offers a full range overflows following your dredge pump capacity and hopper length. Please share your requirements including stroke and diameter.
Jet water monitors
A hopper discharge operation can be enhanced by ensuring that the full load is discharged in the shortest possible time frame. The discharge process can be speeded up by directing a controlled water jet to areas where cargo remains. This job is easily done by a jet water monitor allowing both vertical and horizontal movement, simply controlled from the wheelhouse.
Bow coupling & rainbow nozzle
Discharging over the bow of a hopper dredger is a practical way to deposit a sand cargo where it should be delivered. A bow coupling unit with floating pipe line, a rainbow nozzle and a batch of dredge valve form a practical dredging package which will enable you to upgrade your hopper dredger, making it fit for land reclamation projects.

Your partner in dredging
Dredging requires more than just shipping a dredge valve or overflow. It requires more gear such as dredge pumps and instrumentation to optimise the job. Moreover it requires crew training and project management to bring the works to a successful conclusion. Damen can assist you during the full lifecycle of your dredger.
For a retrofit or newbuild, first class dredging components will allow you to do your dredge job in the most efficient way. We supply a wide array of dredging systems ranging from single components to complete trailing suction pipe packages.
As well as shipping the dredging components to your yard, we can also send over our Field Service Engineer to assist the crew with installation and start-up. This will shorten the installation time, and give an opportunity for crew training.
For spares, repairs, alterations or additions to your dredge systems, our Service team is available 24/7.
