Course Description

436-Marine Weight Estimation and Control

This Continuing Education course is written for Professional Engineers and others who are designing, or want to design, successful floating vessels.

This course is intended to show how important a well-designed and understood weight estimation calculation is to the overall success of a floating structure. Software is provided which establishes a format for the student, that the author has used in the successful design of several hundred ships, boats, barges, submarines, and yachts. There are many examples of ships on video that are examples where proper weight estimation and control was not exercised, resulting in poor trim, heel, bad stability, insufficient freeboard resulting in reduced cargo capacity, underwater swim platforms, and even sinkings during launching. The student’s understanding of the critical nature in establishing a proper foundation for the design of floating structures by paying specific attention to the weight estimate. The following topics are covered:

Conceptual Design Estimation
Reference Axes Used In Shipbuilding
Weight Margins
Organization of Weight Groups
Calculation of Moments
Summation of Weight Groups
Determination of Resultant Lever Arms
Basics of Heel and Trim as they relate to the Center of Gravity

Software Program is Provided

Course Goals: The reader should be able to develop a Marine Weight Estimate of suitable detail and accuracy to provide the basis for the stability calculations necessary for a successful floating vessel.

Interesting course. I think a better definition of LCB ends to be clarified and its relation ship with LCG. Also the terms "trim down by the bow" trim down by the stern" could be clarified with a couple of digarams.
