Ground Reactions

GHS calculates the upward force due to the grounding of a ship, where the water buoyancy may or may not be present in addition to the grounding force. It allows a number of points of ground contact and is not limited to the classical pinnacle and shelf grounding models.

An advantage of this method is that the grounding forces automatically respond to the position and attitude of the vessel.

With accurate grounding as part of its modeling process, GHS is able to calculate realistic stability and strength and to accurately predict the conditions necessary for refloating.

For this reason (and others) GHS is used and preferred by salvage engineers and has been an important part of many successful salvage operations.

The ground reaction mechanism is also useful for launching and drydocking calculations.
