Design Principles for Ocean Vehicles (13.42)


Course Meeting Times

Lectures: 2 sessions / week, 1.5 hours / session

Course Description

The course will cover the basic techniques for evaluating the maximum forces and loads over the life of a marine structure or vehicle, so as to be able to design its basic configuration. Loads and motions of small and large structures and their short-term and long-term statistics will be studied in detail and many applications will be presented in class and studied in homework and laboratory sessions. Issues related to seakeeping of ships will be studied in detail. The basic equations and issues of maneuvering will be introduced at the end of the course.

Three laboratory sessions will demonstrate the phenomena studied and provide experience with experimental methods and data processing.

There will be two In-class (1.5 hours) exams, weekly homeworks, two laboratories and a final project. The exams will be open book/open note exams. The grades for the course will be based on the following:

Activities Percentages
Two Quizzes 50%
Labs/Projects 35%
Homeworks 15%

Individual Work

Each student will work individually on the homeworks, projects, and quizzes.
