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.

  • Interactive, configurable Load Editor Windows + Condition Graphics interfaces
  • Multiple tank modes: intact, flooded, damaged, spilling, bubble, deck water, WDF, frozen
  • Multiple free surface models: CG_shifts, FSM, combined, floor values
  • Advanced wind heeling moment methods: band and 3D panel methods
  • Grounding & drydocking
  • Thrust & external pull forces
  • Longitudinal strength
  • Floodable lengths
  • Grain stability
  • Probabilistic damaged stability
  • Cross-flooding calculations
  • Automatic class criteria checking
  • Water-on-Deck stability
  • MODU and variable axis stability
  • Crane operations
  • MARPOL Outflow
  • Submerged bodies,
  • Variable density cargo,
  • Staggered heel/flotation plane conditions (hopper dredges, barges, etc.)
  • Any compartment damage combination
  • Fully customizable output formatting (any language)

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 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.
