EN247: Principles of Naval Architecture and Marine Engineering
Catalog Description
EN247: Principles of Naval Architecture and Marine Engineering (2-2-3)
This course, which is intended for midshipmen majoring in naval architecture, provides an overview of topics paramount to ship design. Topics include introductions to engineering design, engineering graphics, numerical methods, buoyancy, ship structures, and marine propulsion systems. A design project is used to provide students with a hands-on experience in designing a simple vessel.
Textbook
- Introduction to Naval Architecture (Gillmer and Johnson 1982)
Goals
Upon cmpletion of this course, students should be able to:- Understand the ship design process
- Know the parts of a ship, including the structural components and machinery
- Make engineering drawings, including general arrangements and linesplans
- Neatly present calculations of buoyancy, form coefficients, weights-and-centers, and upright stability
- Recommend a hull form and propulsion system based on the resistance components and operational profile
- Remember ship types, shipyards, regulatory bodies, professional societies, graduate programs, and career opportunities
Prerequisites
ENM Major or Approval of NAOE Department Chair

Computer Usage
Students are required to make extensive use of Microsoft Excel spreadsheets, including self-programmed and built-in functions. MAXSURF and Rhinoceros are also used extensively for ship modeling and associated computer-aided engineering efforts. Students will also be introduced to various MATLAB-based data acquisition functions/scripts, as applicable.
