Non-linear time domain hydrodynamic analysis of fixed and floating vessels with or without forward speed, including calculation of global motions and local pressure loading on the vessel.

Wave loads on Vessels with Forward Speed
Wasim is a hydrodynamic program for computing global responses and local loading on vessels moving at any forward speed as long as the vessel is not planing. The simulations are carried out in the time domain, but results may also be transformed to the frequency domain using Fourier transformations.

The program solves the fully 3-dimensional radiation/diffraction problem by a Rankine panel method. For these methods panel models are required for both the hull and the free surface. Wasim has its own mesh generator, with the geometry of the hull being supplied by the user.

Benefits:

• Improved understanding of structural behaviour in various sea states leads to more optimal designs and safer ship operation
• Ships can be operated more safely by providing ship’s Masters with the necessary information for selecting speed and heading in rough seas
• Fuel consumption can be reduced by comparing design alternatives and thereby optimise wave resistance
• Passenger comfort may be improved through better understanding of a ship’s motion characteristics
