EN358 Ship Structures Notes for an Undergraduate Course
Year: 2008 Language: english Author: P.H. Miller & J.W. Stettler Genre: Handbook Format: PDF Quality: eBook Pages count: 137 Description: In ship structural design, the naval architect is challenged by the large and uncertain forces, the realities of quality control in a shipyard, the ripple influence of their decisions and economics. A simple decision such as whether a deck plate should be 3/8” or the slightly thicker 10 mm will greatly influence stability and cost, particularly when the main deck of a tanker can be four acres in size. Adding to the naval architects’ concern is the applicability of the available analytical models. Traditionally, naval architects use structural design guides and rules formulated by non-governmental Classification Societies. These guides are based on fundamental structural theories combined with empirically derived adjustments. The guides do not cover all the required structure however, and are not considered sufficient for a complete design. The naval architect must use the available theories correctly to avoid either wasting the owner’s money or causing a structural failure. More frequently, the guides are used to complement finite element analysis (FEA). This tool allows the naval architect to combine multiple theories simultaneously in a graphical interface. While it has a steep learning curve, FEA can yield more efficient structure more quickly than other methods. EN358 uses material previously learned in statics, dynamics, material science, strength of materials, stability and buoyancy, and principles of naval architecture. Hopefully the student kept their texts and notes! These course notes are designed to supplement material presented on the board and in Chapter 4 of the book, “Principles of Naval Architecture, Vol. 1” (PNA). Included are administrative materials, the assignments, and basic notes. You should bring these notes to every class and lab! The notes also have some questions, blank spaces for equations, and sample exercises which the student should complete as a study aid. You should print these notes and put them in a 3-ring binder. Add in your work and additional notes in the appropriate spots during the semester, and you will have a complete reference for ship structural design!

Description: In ship structural design, the naval architect is challenged by the large and uncertain forces, the realities of quality control
in a shipyard, the ripple influence of their decisions and economics. A simple decision such as whether a deck plate
should be 3/8” or the slightly thicker 10 mm will greatly influence stability and cost, particularly when the main deck of a
tanker can be four acres in size. Adding to the naval architects’ concern is the applicability of the available analytical
models. Traditionally, naval architects use structural design guides and rules formulated by non-governmental
Classification Societies. These guides are based on fundamental structural theories combined with empirically derived
adjustments. The guides do not cover all the required structure however, and are not considered sufficient for a complete
design. The naval architect must use the available theories correctly to avoid either wasting the owner’s money or causing
a structural failure. More frequently, the guides are used to complement finite element analysis (FEA). This tool allows
the naval architect to combine multiple theories simultaneously in a graphical interface. While it has a steep learning
curve, FEA can yield more efficient structure more quickly than other methods.
