RAOs for a Floating Cube

February 14, 2017

Finally it is time to solve the equations of motions in the frequency domain for a floating cube. In fact, this is a floating cuboid, since the height of a structure is twice the draft and only the displacement part of a structure is a cube. The center of gravity is at the flotation point (0.0, 0.0, 0.0).

In order to solve the equations of...

Wave Loading on a Floating Cube

February 06, 2017

Wave loading on a floating cube is calculated by assuming the small amplitude waves.

Direct integral formulation is used again to calculate the wave forcing (for the diffraction part), water depth is assumed infinite and waves are coming from three different headings (0 deg, 45 deg and 90 deg). Irregular frequencies are also not being removed....
