Single Point Grounding

A new Single Point Grounding option has been added to LoadmatePlus version 7.30.1.

When this option is selected, the attitude of the vessel, grounding force and longitudinal strength. can be determined. The position of the grounding point and the depth of water over it, must be entered by the user. Note that the grounding point co-ordinates are relative to the vessel’s axis system.

The longitudinal position of the grounding point can be given either as a frame position and offset,
or as a distance from the axis origin. The program will automatically convert between them. If the calculation results in a negative grounding force, the program assumes the vessel is floating freely and will re-calculate the floating trim and draft.

When using single point grounding, the user should be aware that the vessel can easily become unstable, and if this happens, a “Maximum number of iterations…” message will probably be displayed. This usually implies that the vessel has capsized. Specifying a higher water level, will often rectify the situation, but it may be necessary to adjust, or reset, the balancing parameters.

Note that a stability (GZ) curve cannot be calculated, when the grounded option is selected.
