- Abstract
- The motions and drift forces of side-by-side (SbS) moored FSRU (Floating Storage & Regasification Unit) and LNGC (Liquefied Natural Gas Carrier) including sloshing are studied by numerical methods and experiments. FSRU and LNGC have LNG cargo tanks and sloshing affects the motions due to the coupling between sloshing and floating body motions. Gap flow also affects the motions and drift forces of FSRU and LNGC. Sloshing is calculated by the pendulum model and NS (Navier-Stokes) VOF (Volume of Fluid) method. The effect of sloshing on the surge, sway motion and drift forces is confirmed. The numerical results agree with the experiments. It is noted that sloshing occurs in longitudinal mode and affect the surge motion and mooring load. Copyright ？ 2012 by the International Society of Offshore and Polar Engineers (ISOPE).
