Q: I have input the wind and current loads as data tables. Does MOSES track the point associated with this to then compute wind and current loads? REV 6.01 A: MOSES uses the global location of the point defined on the #TABLE command to decide whether…

Q: What is the best way to specify a one minute wind speed to MOSES? REV 7.00 A: Wind speed in MOSES is always with reference to the 1 Hour Wind Speed. Use the option -W_DESIGN API 60 or -W_DESIGN NPD 60 This will use either the API or NPD formulation…

Q: Can I input a user defined wind spectrum? REV 7.00 A: Yes. Please see the -W_SPECTRUM option with the &DEFAULT or the “&ENV -W_HISTORY “ command.

Q: Is the static angle due to wind included in the "Cargo Force Statistics"? REV 7.01 A: No, it is not. Neither is the static component of gravity. (Notice that the heave force is around .1 to .3 instead of being greater than 1) The manual clearly states…
