Present study deliberates on the numerical analysis of a new, bean-shaped, multi-body floating wave energy converter (BFWEC) using an open-source time-domain modeling tool called WEC-Sim (Wave Energy Converter SIMulator). The proposed device is a directionally-insensitive, floating-point absorber with a set of bean-shaped floats attached circumferentially around a central cylinder or buoy (CB or CS), extracting the wave energy under heave degree due to the relative motion of the floats with CB. The shape and arrangement of the floats around the CB make the BFWEC different from other existing devices. Authors propose three different layouts of BFWEC with multiple floats, namely: 4, 6, and 8, to study the influence of float's number on the device's overall performance. All layouts are incorporated with a linear damping power take-off (PTO) system to estimate absorbed power where the influence of damping on the performance is studied. The frequency-dependent parameters required to initiate time-domain analysis are obtained from the boundary element method (BEM). The influence of multi-float interactions on performance is assessed over an isolated single float arrangement. The Levelized Cost of assessment (LCoE) of BFWEC is calculated for various sea states of the Arabian Sea and the Bay of Bengal.
