This paper presents a numerical investigation on the hydrodynamic performance of sandglass-type FPSOs with four different cross sections. In order to estimate the hydrodynamic performance and utilise the results in the design stage of FPSOs, a frequency-domain numerical simulation program, ANSYS/AQWA software package, has been used. Numerical results were compared with experimental data and good agreement has been achieved in small amplitude regular wave cases. Based on the simulation results, it is concluded that polyhedral cross sections (especially 10-sided cross section) provide similar hydrodynamic performance compared with circular cross section in heave and pitch motions for all ranges of wave frequency. Therefore, it is possible to use these types of cross sections for FPSOs because of manufacturing simplicity.
