Analytical approach to modeling the interaction between submerged elastic
structures and non-stationary loads has long been recognized as an attractive tool of
engineering analysis, especially at the pre-design stage where it has been particularly valued
for its high computational efficiency. At the same time, the approach has a number of
limitations, the most regrettable one being its inability to handle geometries that are more
complex than the basic ones such as a spherical or cylindrical geometry. We present an
attempt to overcome this limitation while still preserving the much favored computational
efficiency by introducing a hybrid methodology that combines the analytical and finiteelement
approaches. We then validate the methodology using available experimental data and
show that a good agreement with the experiments is observed.
