Hydromax calculates the net load from the buoyancy and weight distribution of the model. That data is then used to calculate the bending moment and shear force on the vessel.

Longitudinal Strength Analysis Requirements

§   Loadcase (including distributed loads if required)

§   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)

Longitudinal Strength Analysis Options

§   Fluid Densities

§   Treatment of fluids in tanks: fluid simulation is always used for Longitudinal Strength analysis

§   Wave form

§   Hog and sag

§   Grounding

§   Damage

§   Compartment definition (in case of damage)

§   Allowable shear and bending moment

The longitudinal strength graph and tables contain all information on weight and buoyancy distribution, the shear force and bending moment on the vessel. If defined, graphs of allowable shear and bending moment are superimposed on the graph.

For more detailed information please see Longitudinal Strength on page 84.
