omvac diez - Dredgepoint

NODOSA SHIPYARD HAS RECENTLY DELIVERED THE TRAILING SUCTION SPLIT HOPPER DREDGER "OMVAC DIEZ",
WHICH IS A KIND OF MULTI-PURPOSE VESSEL SPECIALIZED IN CARRYING OUT DREDGING, LANDFILLS AND MARI-
NE REARRANGEMENTS.
The "OMVAC DIEZ" is a self-propelled ship with the particularity that is split. It has two independent hulls that open to drop its load and deposit
it at the agreed place of the sea bottom. In addition, to transport the material aboard there is a hopper with capacity for 1200 m 3 .
This ship is equipped to perform various operations of maritime work, especially designed for dredging up by suction pump, although it also
can dredge with a backhoe which is located on a rolling platform hosted on top of the hopper. Of course, it can be used simply as transport
dredging products... For all these reasons its versatility is more than demonstrated.
1200 M3. TRAILING SUCCTION SPLIT HOPPER DREDGER
“OMVAC DIEZ”
BUILT BY NODOSA
MARÍN, 2011

Dredging activity is mainly performed by suction pump, and can dredge up to a maximum depth of 30 meters. This pump can fill the hopper with sand in 1.5 hours, which
gives a very high speed of work. It can also dredge mud, in which case the team is able to fill the hopper with a concentration of mud up to 80%.
“OMVAC DIEZ”
His team of dredging is completed with a comprehensive system of control over it for a more
efficient and productive work. Such a system includes dredging, production meter tube position
indicator, indicators of pressure after the pump dredging and vacuum in the suction
of the pump, pump speed, velocity of the liquid in the pipe and concentration of pulp, etc.
NODOSA Shipyard has recently delivered the Trailing Suction Split Hopper
Dredger "OMVAC DIEZ", which is a kind of multi-purpose vessel specialized in
carrying out dredging, landfills and marine rearrangements.
The downloading of the material may be carried out in two ways:
■ One, with the opening of the town, in free fall, either instant or controlled.
■ The other, with pump of dredged by the bow of the ship, driving water pulp and/or arid land by a floating pipe, in which case the ship can download up to 750
meters of distance.
Both ways are ideal for work required in most tourism-dependent countries: the regeneration of beaches.
For propulsion the dredger has two engines diesel CATERPILLAR, each coupled to SCHOTTEL azimuth thrusters, with 360º turn. This gives the ship a great manoeuvrability,
which is increased with the help of a lateral supporter in bow. Thus, the evolution of the ship is minimal, and can operate in areas very low, similar to its
own length.The dredger "OMVAC DIEZ" reaches a speed up, freely and without charge, about 10.5 knots, and meets all the regulations in Spain as a ship in the III
Group, T Class, so it is equipped with the corresponding services and prepared to be able to move from a port to another with an average of 3500 nautical miles of
autonomy. In addition to suction dredging ship, as is said, is designed to perform another type of maritime works, such as the transport of products derived from the
normal activity of dredging, or jetties, aggregates, etc. Also the vessel can perform dredging with backhoe, which is on a sliding bridge up and along the hopper, with
two areas for stowage the machine at each end of it.
The ship is subject to SOLAS rules, and is classified by the company GERMANISCHER LLOYD, ✠ Class 100A5, RSA(50), Split Hopper Dredger, ✠ Hull, (✠) MC.
Dimensions and technical characteristics of this vessel, which has been designed and developed with close collaboration between the technical offices of NODO-
SA and F. CARCELLER, are summarized on the Technical Data of the ship that you may request to NODOSA.
As you can see, with the exposed features, the ship is a powerful and versatile unit of dredging, fully operational and very productive, ready to meet the desire for
which it was conceived by the Shipowners.
