WAMIT® is the most advanced set of tools available for analyzing wave interactions with offshore platforms and other structures or vessels. Since the announcement of Version 1 in 1987 at MIT, WAMIT has gained widespread recognition for its ability to analyze complex structures with a high degree of accuracy and efficiency. Over the subsequent years WAMIT has been licensed to more than 90 industrial and research organizations worldwide.

WAMIT Version 6.3 is the latest in a progression of more powerful and versatile programs. Version 6, which has been available since 2000, represents a quantum jump in the capabilities of WAMIT, including a higher-order method of solution and various options for defining the geometry. Version 6.1 and Version 6.1S have been available since 2002. Version 6.1 has an option to link WAMIT with the Relational Geometry Kernel of the CAD program MultiSurf facilitating a seamless transition from design to hydrodynamic analysis. Version 6.1S, has the additional capability of complete second-order nonlinear analysis in bichromatic and bidirectional waves. Version 6.2, released in 2004, has the capability to analyse internal tanks with free surfaces coupled with the dynamics of vessels.

WAMIT Version 6.3 is now available with various extensions and updates from Version 6.2, including the capability to evaluate all components of mean drift forces and moments on structures from the momentum flux through a control surface surrounding each structure. Additional extensions include the efficient analysis of the wave field generated by one or more wavemakers in a wall, and the output of the hydrostatic coefficients for all modes including the generalized modes. Details of the Version 6.3 upgrade can be found here.
