Manson Hopper Dredge

The M/V Glenn Edwards is a 12,000 cubic yard hopper dredge, owned and operated by Seattle’s Manson Construction. This trailing suction hopper dredge is the newest and largest hopper dredge in the U.S. fleet.

We Love a Challenge

Unusual among large hopper dredges, the Glenn Edwards is propelled by three 1,920 kW azimuthing Z drive units fitted with nozzles. The open top construction, as well as the unusual proportion and form of the vessel, required special consideration.

Attention to Detail

Hal Hockema & Associates led the design. Glosten supported the design team with full-vessel finite element analysis of the structural design to obtain ABS classification for open-ocean unrestricted service. We also managed a formal CFD hull optimization and model test program resulting in 10 to 20% resistance reductions.

Proven Performance

Glenn Edwards was built at Alabama Shipyards. The vessel can load 13,500 cubic yards of silt. Once full, the vessel travels to an offshore disposal site where the material is dropped by opening the doors in its hull that are 14 feet by 21 feet.
