Wave loads on stationary vessels

HydroD is a tool for hydrostatic and hydrodynamic analysis. By integrating these tasks significant cost savings may be achieved in the engineering phase since the same panel model may be used by one tool.

HydroD will perform compliance checks against statutory rules for stability including the importance of integrity of the deck tanks. Floating positions may be determined as a result of actual mass and buoyancy or from an automatic compartment filling to satisfy specified position.

The hydrodynamic analysis may be performed using the actual floating position – and independent of the panel model – to determine worst loading conditions to be used in structural strength analysis. These analyses are normally performed in the frequency domain, but it is also possible to do it in time domain (Linear as well as non-linear).

The loads (pressure and accelerations) are automatically used by the structural analysis. The response and loads may be graphically assessed in animations.

MODULES:

Frequency domain hydrodynamic analysis - Wadam

Wadam is a general hydrodynamic analysis program for calculating wave-structure interaction for fixed and floating structures of arbitrary shape.
