Vessel Description


The vessel is a self-propelled split hopper dredge. It has two independent hulls that open to drop its load of spoil and deposit it at the agreed place on the sea bottom. The hopper has a capacity of 1200 m3. This ship is equipped to perform various operations of maritime works, especially designed for dredging up by suction pump, although it also can dredge with a backhoe which is located on a rolling gantry hosted on top of the hopper. Of course, it can be used simply to transport dredging products... For all these reasons its versatility is more than demonstrated.


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 enables a quick turnaround. It can also dredge mud, in which case the team is able to fill the hopper with a concentration of mud up to 80%.


The dredge master has a comprehensive system of control over dredging for 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 spoil, etc.


The downloading of the material may be carried out in two ways:

·         The opening of the split hopper, in free fall, either instant or controlled.

·         Rainbowing utilising pump off the bow of the ship, and/or by pumping ashore via floating pipe, in which case the ship can pump ashore up to a distance of 750 meters.


For propulsion the dredger has two CATERPILLAR diesel engines, each coupled to SCHOTTEL azimuth thrusters, with 360º rotation. This gives the ship excellent manoeuvrability, which is increased with the help of a lateral Bowthruster, thus, the vessel can be turned within its own length.  When empty, the dredger reaches a speed of 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 is capable of moving from a port to another with an average of 3500 nautical miles of autonomy. In addition to dredging, the ship is versatile and designed to perform other 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 a Backhoe, which is on a sliding gantry mounted on top of the hopper, with two areas for stowage of the machine at each end of the hopper.


The ship is subject to SOLAS rules, and is classified by 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 the shipyard and F. CARCELLER, are summarized on the Technical Data of the ship which is available from Seaboats.
