OFFSRF: A System for Representing Ship Offset Data

Abstract

It is argued that a standard format for representation of offset data in computer files would save time for both users and programmers of hydrodynamic programs. A system suitable for adoption as a standard is described. It includes standard formats for offset data on stations, on bow and stern profiles, and on transoms, as well as formats for common hull features such as knuckles, bilge keels, the design waterline, the deck edge, and the half-siding. The format is extensible so that additional data may also be included in the offset files. To ease the burden on the programmer, Fortran sub-programs to read the standard data are provided; they provide extensive error checking and accurate pin- pointing of the location of errors in the file. Programmer's manuals for the sub-programs are included. Keywords: Ship hulls; Computer programs; Hydrodynamic; Canada. (JHD)
