Dutch dredging equipment for Omvac Diez

The dredger was built in Spain to a Spanish design but has been fitted out with the Dutch dredging equipment manufacturer’s dredging gear. The vessel has started its productive life performing a harbour maintenance dredging operation in Cadiz.

The Omvac Diez is a split hopper dredger of 1,100 m³ capacity, equipped with a 500mm diameter trailing pipe for dredging to a maximum depth of 30m. The inboard Damen dredge pump of type BP5045 fills the hopper during dredging then empties it via a bow coupling or by rainbowing. The vessel is also equipped with various Damen dredging instrumentation, including that for trailing pipe position, load and draught, density and velocity, and vacuum and pressure measurement.

The 67m long split hopper was designed by the Spanish naval architect Carceller and built in a relatively short time by the Nodosa yard in Pontevedra on the Galician coast. This was the first newbuilding of a split hopper dredger by the yard. Successful cooperation has resulted in an efficient, effective vessel which has a maximum loaded speed of 9.5 knots.

The vessel is currently works with its removable grab crane, a Liebherr type 984, situated at top coaming level.

Spanish dredging contractor Canlemar undertakes maintenance and capital dredging jobs in the Iberian peninsula and in Northern Africa. The company owns a large number of dredging vessels, including several split hoppers. It is situated in the La Coruna province in North Western Spain.

Faustino Carceller S.L. naval architects have done over 200 projects the past two decades, include conversions, lengthenings, new buildings, inspections and stability tests.

The Nodosa yard combines the disciplines of repair, conversion and newbuilding and has built a variety of vessels over the years which, apart from dredgers, also includes fishery vessels, passenger vessels and barges.
