Naval Architecture: The Art and Science of Ship Design Naval Architecture, also known as marine engineering, is a specialized branch of engineering that deals with the design, construction, and maintenance of ships and other marine vessels. It is a unique and multifaceted field that combines the principles of structural, mechanical, electrical, and hydraulic engineering to create the complex systems and structures necessary for safe and efficient marine transportation. The word “naval” in naval architecture may bring to mind images of warships and navies, but the discipline actually encompasses a wide range of vessels, from large cargo ships and oil tankers to luxury yachts and cruise ships.
