Abstract
A mathematical model describing the fundamental dynamics in the interface problem between a ship, a barge, and a connecting ramp is developed and solved. The hydrodynamics for the ship and the barge are described by a 12-degree of freedom fully coupled model, which is based on potential theory and incorporates proximity effects. Ramp structural dynamics are studied by a finite element model, which has been calibrated based on detailed studies of commercially available codes. The models were coupled together through a spring/damper and the solution of the system was obtained in both regular waves and a representative sea state. Parametric studies with regards to different coupling conditions indicate that optimization based on either relative motions or ramp maximum stress is possible.
