Originally a split hopper
barge, the North Wind was converted to a fixed hopper barge with
a hydraulic excavator used to unload the cargo. JLMD was contracted
to design the modification to allow a 30 tonne hydraulic excavator
to be positioned on the aft deck and allow it to drive onto cargo
in the hopper and unload it to an onshore facility.
Initially plans were also conceived to allow the vessel to receive
dredging spoil. Resultant of this, a "de-watering" system
was inbuilt into the design of the hopper closure. Pictures below
show the new hopper bottom / closing plate and the perforated plate
top of the dewatering system. This system allows slurry to be loaded
into the hopper and the water removed so the excavator can unload
the cargo.
