    In the main menu it says metres and Kilonewtons where as in the general tab for water mass density not sure what to apply either kg/m3 or kN/m3 ? If we apply in kN/m3 the wave output shows 10.2 kg/m3 which is not right . It is the water mass density…

    Not very clear with the input regarding the flooded members and appurtenance members in structure member properties in STAAD Offshore. The members classified as “Flooded” will affect the buoyancy calculations because the weight of the water in the…

    Q: What is the difference between damping, drag, drag caused by current, and drag caused by waves? REV 7.04 A: First let's us agree that drag and damping are considered the same. Now, divide damping into radiation damping and viscous damping. The first…

  • "Wave Drift" forces look strange

    Jason Forcier
    Jason Forcier
    Q: Why do my "Wave Drift" forces look strange? REV 7.05 A: You do not have a good panel model for diffraction. Remember, the drift force depends on the gradient of the velocity potential while the first order forces depend only on the potential. Thus…

  • Evaluating relative velocity between jacket structure and wave during tow analysis

    Jason Forcier
    Jason Forcier
    Q: Can MOSES evaluate relative velocity between jacket structure and wave during tow analysis? REV 7.06 A: Yes and No. In the time domain, the forces on Morrisons' elements are evaluated based on the relative velocity. You can get a time trace of the…

    Jason Forcier
    Q: Can MOSES compute wave induced shear force and wave induced bending moment on a ship in the frequency domain? REV 5.07 A: Yes, but perhaps not in the way you think. Other programs that deal with only monohull ship structures may provide this in their…

    Q: Can MOSES analyze the "springing effect" on a ship hull girder in waves? REV 6.02 A: Yes, you need to model the structural attributes of the ship hull, and use Generalized Degrees of Freedom.

  • Generating multiple maximum waves together

    Jason Forcier
    Jason Forcier
    Q: Is it possible for MOSES to generate 2 - 3 maximum waves together in a wave spectrum? REV 7.01 A: Not easily. What you want is something that violates the properties of the wave spectrum; i.e. something that is a quite rare event. What you can do…

  • Meaning of "wave force" when using the &STATUS FORCE command

    Jason Forcier
    Jason Forcier
    Q: What is the meaning of the "wave force" I get when I issue the &STATUS FORCE command? REV 7.00 A: The result of all &STATUS command are applicable to the current, static, condition. As a result, the "wave force" is the mean drift force and the "drag…

    Jason Forcier
    Jason Forcier
    Q: Can I get MOSES to give me a correct wave force on a tank setting on the sea bottom? REV 6.01 A: Actually, you need to do nothing. MOSES automatically eliminates all panels below the mud line. Just make sure that the tank extends below that bottom…
