EN445: Marine Fabrication Methods

Catalog Description

EN445: Marine Fabrication Methods (2-2-3).

This course presents some of the basic techniques used to fabricate offshore structures and ships. Lecture and lab topics develop an understanding of metal, concrete, and composite construction and quality control methods through the manufacturing and testing of small components representative of those used in the marine environment. An understanding of fabrication specifications is developed through group projects in each material category.


Class Notes and Handouts


  1. Have a basic understanding of marine fabrication methods.
  2. Be familiar with industry standard quality assurance and quality control methods through specification development and field and laboratory experiments.
  3. Have an understanding of the influence of fabrication on design.
  4. Be able to work effectively in teams working on multi-disciplinary projects.
