Technical Details

 
Principal Dimensions and Characteristics
   Hull Design:
  The dredge has a center hull containing the main dredge pump, set as low as possible in a dredge pump well.  
  The main pump drive system is multiple banded belts with sheaves.  This belt system has several advantages
  over gear box drives.  First, the belts have sufficient play to allow the adjustment of the dredge pump impeller
  to maintain the proper minimum clearance between the front liner and the impeller.  With a gear box drive, this
  requires a special coupling between the pump and the gear box that can tolerate this movement and yet will
  not fail under high power conditions.  Second, the sheave ratios can be changed, if necessary, for maximum
  operating conditions.  With a gear box drive, this would be impossible without a total gear box replacement.   
  Third, this belt drive allows the engine to be elevated to deck level, facilitating servicing, minimizing water
  damage, and allowing an additional floatation compartment under the engine. Fourth, unlike the gear box,
 

the belts can not fail due to oil contamination, an oil leak, and the loss of oil lubricate.
