Abstract
In this paper we are reexamining the dynamic equations of
an elastically deformable floating structure to identify and evaluate the
contribution from the inertia cross coupling terms which commonly have
been neglected due to the assumption of small structural deformation.
Numerical experiments on two vessels, a flexible barge, and a full scale
ultra large container vessel, are designed for revealing the magnitude of
errors introduced into the numerical solutions when these inertia cross
coupling terms have been ignored. The results shows that in realistic
conditions with strong structural dynamics, the errors are less than 1%
for the flexible barge and less than 0.5% for the ultra large container
vessel.
