Coupled Hydrodynamic/Structural Model for Ship/Ramp/Barge Interface

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.Naval Postgraduate School Monterey CA is the author of 'Coupled Hydrodynamic/Structural Model for Ship/Ramp/Barge Interface', published 2001 under ISBN 9781423524144 and ISBN 1423524144.
