GHS

Hydrostatics – Stability – Seakeeping

GHS is the most comprehensive (in absolute) and powerful (in the microcomputer world) stability calculator. GHS does not stop at calculating static stability parameters, but checks for positive stability in every condition and configuration.
GHS supports variable density cargo, staggered heel/flotation plane conditions (hopper dredges, barges, etc.) as well as any compartment damage combination. Longitudinal strength, floodable lengths, probabilistic damaged stability, automatic class criteria checking, MODU and variable axis stability, crane operations, fully customizable output formatting (any language), etc., are only a few of the features found in GHS

In addition, GHS offers a full depth programming language for the writing of macro routines, and linking to user-developed programs, thereby fully automating work to unrivaled
heights. GHS includes several industry standard interfaces, and supports a large number of printers for the outputting of graphs and tables, and also supports export to Word and html formats.

The Multi-Body module gives GHS the ability to model the interactions of multiple vessels in a wide variety of configurations when latched together or resting on one another.

GHS also offers SeaKeeping capability via its SK optional module. SK is fully integrated in GHS, and performs ship motion calculations using existing geometry files, loading conditions, and run files, making GHS the only software of its kind tighltly integrating the hydrostatic & the hydrodynamic assesments.

The Dynamic Stability  module handles the dynamic stability evaluations according to IMO Second Generation Intact Stability guidelines.
