15,000 cu. yd. Hopper Dredge = “the Cookie Monster” of Beach Replenishment
Manson Construction Co.’s Frederick Paup is the largest Trailing Suction Hopper Dredge in the United States. Designed and built specifically to meet the needs of the U.S. dredging market, she boasts 25,000 HP and volumetric capacity of over 15,000 cubic yards. Utilizing her triple Z Drives and twin Bow Thrusters enables the Frederick Paup to maneuver and dredge within the tightest channels. This further enhances her capability to minimize operational delays as she can maintain performance in the event a Z Drive or bowthruster has a mechanical failure.
The Dynamic Positioning feature adds additional flexibility to hold stationary position or track a designated course while performing dredging operations. The utilization of sealed underwater motors enhances the dredging operation by reducing the suction distance between the drag head and the pump thus making it more efficient. With her two in-hull pumps, the Frederick Paup will enhance Manson’s competitiveness on beach nourishment and coastal restoration projects and help the US Army Corps of Engineers (USACE) meet their goal of 70% of dredged material being beneficially reused by 2030. Being diesel electric and having Tier 4 engines, the FREDERICK PAUP is very fuel efficient and environmentally friendly at a lower cost per unit.
