Conversion or newbuilding
The trailing suction pipe system can be built onto an existing barge or for a new hopper dredger.
In case of a conversion the system is to fit in the current situation on board for which we need drawings of the gangways and the pump room, for example.

For new built vessels the dredging system is designed in close co-operation with the yard in order to get the optimal design.

In consultation with the yard the design of all major systems as dredge lines, jetwater lines and gangway width will be chosen, all in accordance with the requirements of the customer.
Damen Dredging Equipment does not build complete hopper dredgers; we always co-operate with yards in the Netherlands and abroad.
The yard either is a member of the Damen Shipyards Group or it is a separate identity.

Inland waterways or seagoing hopper dredger
The dredging system for an inland waterways dredger is of a special design : the equipment can be constructed lighter as there is for instance no swell.

We always take the hoisting conditions as stipulated by the customer into account.
