Designers: Jonas Armstrong, Addison Harris, Kevin O’Keefe, and Gracie Schmitz
Vessel Type: Inland Waterways Dredge
Mission Requirements:
This self-propelled cutter suction dredger with hopper capacity will support maritime operations within the Nigerian Lagos Lagoon and associated waterways through channel deepening and maintenance dredging. It is designed to operate at extremely shallow drafts and has capability for offshore discharge of spoils.
Operating Modes:
▪ Discharge through bow nozzle during dredging
▪ Discharge through floating pipeline during dredging
▪ Dredging spoils to hopper for intermediate storage
▪ Hopper discharge through hopper doors, bow nozzle, or pipeline

About Junior Class Small Vessel Design Project (SD1):
As a part of Professor Bradley D.M. Golden’s ’99 Ship Design 1 (SD1) class, the juniors spent the first two-and-a-half months of the spring semester preparing their first complete concept designs.
Using the knowledge they’ve gained in their nearly three years studying at Webb and the experiences from their winter work periods to date, this was the students’ first opportunity to apply the naval architecture and marine engineering principles they’ve studied including stability, ship’s structures, main machinery systems, auxiliary systems, resistance and propulsion, and electrical engineering.
Working in small groups of three and four, the students selected one of the vessel types and took their first couple of spins around the design spiral to prepare vessel concept designs. To help make the project as realistic as possible, members of industry familiar with each of the vessel types helped prepare the statements of design requirements that each of the designs had to meet. To challenge the students even further, one or two “curveballs” were thrown into each design statement to make the students think long and hard about how they would achieve their objectives.
At the end of the spring semester, the students presented their final designs to their fellow students, faculty, and members of industry who served as part of an evaluation team. After three years at Webb, the Junior class can now say with confidence that they’re familiar with the design process and are well on their way to joining the fields of naval architecture and marine engineering.
