A Verification Document
is available where MOSES results
are compared with results for the same problem obtained by
other means.

*Hint:* Use the zoom tool in Acrobat to better view the equations.

The source of the MOSES results is from the set of samples listed below.

*STRIP THEORY:*

This sample is used to verify strip theory calculations. Answers from this analysis are used in a comparison with model test results.

*3D DIFFRACTION THEORY:*

This sample performs a Three Dimensional Diffraction analysis in the frequency domain of the semisubmersible Balder. Results of this analysis are used in comparison with model test results.

*WIND AND CURRENT FORCES:*

This sample performs looks at different ways of computing wind and current forces. It also looks at the damping produced by these "current force" attractors.

*PIPELAYING:*

This sample computes the configuration of a pipe being layed in 1600 meters of water. Results of this analysis are used in comparison with results from the computer program OFFPIPE.

*TANKER MOTIONS:*

This sample analyzes the horizontal oscillation of a single point moored tanker exposed to head wind and current.

*WAMIT TO MOSES COMPARISON:*

J.Ray McDermott prepared a comparison of the hydrodynamic results computed by WAMIT and MOSES using 3D Diffraction. Five different models were studied: a simple box, a vertical cylinder (SPAR), a general ship form, a TLP and a semisubmersible. Added mass, damping, wave excitation and RAO information is presented. results show favorable agreement between the two programs, click here to view the report
