Multi-Body

The Multi-body module allows General HydroStatics (GHS) and GLM (GHS Load Monitor) software to handle multiple floating bodies with points of contact between them. Ground contact can be included simultaneously.

Applications include:

onboard load monitor for tug-barge units;

detailed simulation of loading and unloading floating objects by partially submerging the carrier;

complex salvage procedure modeling;

ice breaker simulation;

dry docking;

articulated floating structures.

Equilibrium of the entire multi-body system is found automatically and the forces at the points of contact are reported.

This new capability is available through an optional software module being called simply "Multi-Body" or MB. It is tightly integrated with GHS so that the usual features of the program can be used in conjunction with it.

The MB module allows GHS to model the interactions of multiple vessels in a wide variety of configurations when latched together or resting on each other. It models each vessel in a separate side-by-side session of GHS and quickly solves for simultaneous equilibrium whenever anything in the system changes. For example, the effect of changing the load in a tank on one vessel can be seen also in the draft, trim and heel of the vessel with which it is in contact as well as in the contact force. The contact forces are automatically included in stability, longitudinal strength and torque calculations.
