Equilibrium Analysis uses the Loadcase, to calculate the displacement and the location of the centre of gravity. Hydromax iterates to find the draft, heel and trim that satisfy equilibrium and reports the equilibrium hydrostatics and a cross sectional areas curve.

Equilibrium analysis requirements

§   Loadcase

§   Tank definition in the case of tank loads being included in the Loadcase (and/or for the definition of damage)

§   Compartment definition and damage case (in case of damage)

Equilibrium analysis options

§   Fluid Densities

§   Treatment of fluids in tanks: fluid simulation or corrected VCG

§   Wave form

§   Hog and sag

§   Grounding

§   Damage

§   Compartment definition (in case of damage)

§   Key points

§   Margin line and deck edge

§   Analysis of equilibrium criteria

Equilibrium analysis result table lists the hydrostatic properties of the model. If a wave form has been specified there will be a number of columns; each column contains the results for a different position of the vessel in the wave as given by the wave phase value. The sectional area curve is also calculated, as is the freeboard to any defined key points, margin line and deck edge. Any equilibrium criteria will also be evaluated and their results reported.
