The split hopper dredger“Omvac Diez” has been handed over to its owner Canlemar after successful sea trials. The dredger has been built in Spain to a Spanish design yet has been fitted out with Dutch Damen dredging gear. The vessel has started its productive life already, doing a harbour maintenance dredging job in Cadiz.
The “Omvac Diez” is a split hopper dredger of 1.100 m3, equipped with a 500 mm trailing pipe for dredging at max – 30 m. The in board Damen dredge pump, type BP5045, both fills the hopper during trailing as well as empties the hopper using the bow coupling unit or rainbow nozzle. The dredger has various Damen dredging instrumentation systems, such as trailing pipe position, load & draught, density & velocity and vacuum & pressure measurement.
The 67 m long split hopper dredger has been designed by the Spanish naval architect Carceller. It has been built in a relatively short time span by the Nodosa yard in Pontevedra on the Galician coast, of which it was their first newbuilding of a split hopper dredger. The successful cooperation has resulted in an efficient, well-performing vessel with a max loaded speed of 9.5 kn.
The split hopper dredger currently works with its removable grab crane, a Liebherr type 984, situated at top coaming level. The versatile dredger is currently doing a maintenance job, and there are many more to come.
