This hopper dredger has been named “Fabio Duò”  in memory of the untimely demise of the former shareholder of Vittoria Shipyard S.p.A.. This vessel is provided with bottom doors activated by four hydraulic pistons, and a Liebherr HS 895 HD slewing crane for the grab bucket with a capacity of 200 tons.

Such unit has an Overall Length  of 80,90 metres, a Length Between Perpendiculars of 78,4 metres, a beam of 16 metres and a gross tonnage of 1.700. At the 4,3 metres draught the dredger can carry 3.000 deadweight tonnage, its maximum speed is 12 knots and it provides accommodation for 8 crewmen. The vessel is classified by RINA in MEDITERRANEAN navigation: within twenty miles of the coast and twelve hours maximum journey.

Thanks to the Liebherr HS 895 HD crane, the “Fabio Duò”  can perform the excavation of seas, lakes, lagoons and rivers seabed and transport the resulting material. Several applications of the cableway drag scraper are:

  • Lifting with 200 tons of maximum load in release
  • Dragline excavation, a branch that seemed destined to succumb, but thanks to its high performance equipment (such as the HS 895 HD crane) it benefits from a renewed interest from industry professionals
  • Fast and productive dredging, an unthinkable task in the past
  • Maritime works  useful for the realization of extreme engineering projects
  • Excavation and realization of the foundations for subsoil reinforcement works
  • Construction and demolition with almost 100 metres of available arm

Mounted without undercarriage, the Liebherr HS 895 HD is directly fixed to the hull, melding with the structure of the ship.  Designed to operate in the most demanding conditions, the strong arm and the structure allow the crane to operate with large hydraulic or mechanical excavation and dredging equipment (buckets / grapples), ensuring exceptional performances.
