... to protect pipelines against large deformations. This kind of pre-excavated material usually gets highly remolded and becomes considerably softer than the native seabed soil. The shear strength difference between the backfilling and seabed soil can result in the pipeline-backfill-trench interaction during...

... ABSTRACT The dynamic response of a marine rudder located in the wake of a propeller is analysed by the one–way fluid structure interaction approach. The time dependent loads on the rudder are obtained through Detached Eddy simulation and are used as input for a structural solver to determine...

Fang and Kim (1986) analyzed the wave induced motion on two slender bodies with close space and hydrodynamic interaction in oblique waves. Comparing with the motion of a single vessel, it's found that the interaction...

... involves the hydrodynamic and structual interactions of multiple bodies. In this study, a numerical model for predicting motions and loads during the floatover operations is proposed. The model considers the effects of multi-body hydrodynamic interaction, DSU and LMU structural connections, mooring systems...

... and degrees of structural blockage increase in size, the question arises as to which extent a large jacket foundation can still be classified as hydrodynamic transparent. In-depth understanding of the current and wave induced flow field around jacket structures has yet to be achieved. The interaction...

... ABSTRACT A fully nonlinear method base on potential flow theory is proposed to simulate nonlinear interaction between incident waves and semi-submersible. In the boundary element method (BEM), auxiliary functions are introduced to calculate wave forces indirectly after the boundary integral...
