Introduction Together with the size and weight of offshore floating structures becoming continually improved to meet the wants for exploiting various sources from the ocean, the multi-module floating method has turn into increasingly well-liked on account of its advantages like the ease of fabrication, transportation, and installation at the same time because the reduction on the general waveinduced longitudinal loads. Quite a few applications of such systems is often found in offshore and ocean engineering, as an example, the floating pier [1,2], floating airport [3,4], and Mobile Offshore Base (MOB). In addition, numerous operations may BMS-8 custom synthesis involve numerous floaters operating in close proximity with temporal connections, including the side-by-side operation of an FLNG and an LNG carrier [5] along with the catamaran float-over deck installation for a floating Spar platform [6,7]. Different from a single floater, the multi-module floating method could involve complex hydrodynamic interactions and dynamic interactions involving various modules through the connectors [80]. This complicated difficulty has attracted enormous interest in the field of naval architecture and ocean engineering. Considerably literature has beenCopyright: 2021 by the authors.

Eng. 2021, 9,2 ofdedicated to investigating the hydrodynamic and dynamic interaction difficulty amongst many bodies in waves for decades, one example is, the experimental research [11,12] and theoretical analyses [13,14]. Meanwhile, numerical investigation has gradually grow to be an essential method for investigating multi-body hydrodynamics, with all the continuous improvement of computers’ computation capability along with the advancement of numerical models. Wang et al. [15] adopted the linear potential flow theory to study the hydrodynamic interaction amongst two semi-submersible sorts of VLFS modules in the frequency domain. Li et al. [16] built a numerical wave tank depending on the completely nonlinear possible flow theory to investigate the fluid resonant phenomenon at the gap in-between the adjacent floating bodies. Their benefits showed that the dominant resonant mode could transfer from the piston form towards the sloshing form because the gap distance increases from narrow to wide. In some circumstances, it is essential to account for the second-order effects which include the imply drift forces and more complex time-varying nonlinearities [17]. In this regard, Sun et al. [18] applied a second-order diffraction code DIFFRACT to investigate the water wave diffraction by two parallel closely spaced rectangular barges, plus the partnership among the wave frequencies, wave force amplitudes, and gap width was presented. Based on the linear possible flow theory, frequency domain hydrodynamic evaluation of your multi-body method can be readily performed by the common panel codes for instance AQWA [19]. Nevertheless, th.
