CAD/CAM

GHS is one of the computing tools used in the Computer-Aided Design and Manufacturing process for ships and boats of all types. It accepts data from drawing and solid-modeling software including all major drawing programs and most of the ship hull development software programs. GHS produces data necessary for the evaluation of the cargo capacity, longitudinal strength (shear and bending) and stability performance of ship designs.

Very often complete 3-D models of a ship and its internal subdivisions and tankage are generated within GHS by the geometrical modeling tools supplied in the GHS system. The level of detail is suitable for trim and stability analysis, not construction drawings. But if this is done in a preliminary design activity, the geometrical information can later be exported for use with CAD drawing programs as the basis for detailed design.
