Radiation Damping Coefficients

Theory

The layout of the radiation damping terms is shown below and this can be repeated as often as necessary to define the radiation damping over a sufficiently large range of frequencies:

FREQ= Frequency

where:

•Frequency is the frequency value in Hz, to which the coefficients relate

•C11 is the surge radiation damping at the relevant frequency

•C22 is the sway radiation damping at the relevant frequency

•C33 is the heave radiation damping at the relevant frequency

•C44 is the roll radiation damping at the relevant frequency

•C55 is the pitch radiation damping at the relevant frequency

•C66 is the yaw radiation damping at the relevant frequency

and the remaining terms represent the radiation damping terms between various degrees of freedom at the relevant frequency.
