NUMERICAL ANALYSIS OF THE EFFECTS OF A SANDGLASS-TYPE FPSO HULL FORM ON HYDRODYNAMIC PERFORMANCE IN REGYLAR WAVES

Designing an optimum FPSO hull form needs years of experiment and knowledge due to complicated interaction of current, wave, body and many other important factors including inclination angle. Analysis of the problem is very complicated due to nonlinear interactions and the coupled equations. Therefore, many experimental and numerical studies have been carried out to examine the effects of FPSO hull form on hydrodynamic performance in regular and irregular waves. In recent years, sandglass-types of FPSO have been presented as an attractive form for the improvement of hydrodynamics performance in rough seas. References [1] and [2] are examples ofexperimental and numerical researches on this subject. However, it seems there has not been much attention to inclination effects on hydrodynamic performance ofsandglass-type FPSOs.
