Largest Self-Propelled Hopper Dredger in US History Delivered

Seatrium delivered FREDERICK PAUP to Manson Construction Co. Built at Seatrium’s Brownsville Texas yard, the Jones Act-compliant vessel is the largest self-propelled hopper dredger in US history.

Key highlights:

• Largest in the U.S. – 420’ length x 81’ beam, with a 15,000+ cubic yard hopper capacity
• Powerful and Agile – Self-propelled with 25,000 horsepower, triple azimuthing stern drives, and twin bow thrusters
• Sustainable – Tier 4 Wabtec Diesel-Electric Engines and an advanced hull form for reduced emissions and improved fuel efficiency
• The vessel is designed with smart features that allow for dynamic positioning, power management, and integrated dredging systems.
• The vessel will support the US Army Corps of Engineers’ goal of achieving 70% beneficial reuse of dredged material by 2030.

Designed and built specifically to meet the needs of the U.S. dredging market, she boasts 25,000 HP -- 3x Wabtec 16V250MDC + 2x Wabtec 12V250MDC -- 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.
