Motion Response Calculator (TheNavalArch)

TheNavalArch launches the Motion Response Calculator

What does this Excel Sheet do?

This tool takes the RAO of the vessel as input and calculates the response spectrum for 6 DOF motions and statistical significant and max response.

The RAO is usually computed for the COG or a fixed origin on the vessel.

This tool can translate the RAOs to another point on the vessel to give the relative RAO and relative responses for that point.
