Two-Dimensional Numerical Modelling of a Moored Floating Body under Sloping Seabed Conditions

A coupled floating body-mooring line model is developed by combining a boundary element model for a two-dimensional floating body and a catenary mooring line model. The boundary element model is formulated in the time domain by a continuous Rankine source, and a reflection potential is introduced to...
