Abstract
A Mariner class ship model vas tested at various shallow water
depths and Froude Numbers constrained to motion in one degree of
freedom, either pitch-no heave or heave-no pitch. Under these constraints,
using a step response technique 5 the response of the model
to a step disturbance in pitch or heave was recorded* This response
was then analyzed to obtain virtual mass or virtual inertia and damping
coefficients in heave and pitch. These results are presented to show
the effects of shallow water on these ship motion parameters at various
Froude Numbers as a function of frequency of oscillation.
