Abstract
The present paper deals with the method to get the faired ordinate and frame offsets from a few input data of principal particulars, using an electronic digital computer. The outline process is as follows. The standard hull form of which data are stored in the computer, is divided into three parts of entrance, parallel and run, and each part is represented by a few body plans which typify the characteristics of the hull form. For the mathematical expressions of water line and body plan, a polynomial and a combination of ellipse and polynomial are used respectively. Modificating these standard lines data, the required lines are obtained. This program has been developed and improved since about four years ago and already applied to several ships built in our Kure Ship Yard.
