EN471: Ship Design I

Catalog Description

EN471: Ship Design I (2-2-3)

The first course in a two semester sequence covering the theory and application of the principles of ship design for naval architecture students. Each student develops the conceptual design of a small, mono-hull displacement ship.  Relevant design resources and techniques are used.

Textbook

• Ship Design and Construction, Volume 1 and Volume 2 (Lamb)

Goals

1. Develop a practical understanding of the ship design process through the feasibility design of a small craft.
2. Be able to apply ABS, CFR, and Navy criteria to a new design.
3. Select a preliminary propulsion system for a new design.
4. Develop a professional presentation (e.g. written) of a naval architecture preliminary design through quality drawings, sufficient calculations, and design trade-offs.
5. Begin team capstone design.
