GeoDredge installation on a PLM Grab dredger

GeoDredge installation on a PLM Grab dredger of Osinga Baggerwerken B.V. on board of the vessel Zeus.


Osinga Baggerwerken B.V. already had a single position DGPS at the top of the crane,
it is now upgraded to a RTK heading system with an encoder on the hoist and close wire of the grab dredger.

With those encoders it can now tell the height of the bucket as well as the bucket is opened or closed.


The system is using a Trimble RTK GNSS with heading and a mobile VRS correction signal of 06-GPS.

The software on the crane: Viking Dredge with Gridding and Networking Module
The software on the vessel: Viking Navigation with Networking Module and Navionics
