“…Due to the complex configuration of a multi-float structure, elaborate theoretical analyses are difficult to be performed. Some researchers simplified the structure into a beam or thin plate and conducted hydro-elastic calculations (Wang and Meylan, 2004;Newman, 2005;Watanabe et al, 2006;Taylor, 2007;Yoon et al, 2014;Karperaki and Belibassakis, 2021). Although being one step forward, these approaches have mainly been applied to the potential flow framework, which is incapable of disclosing the realistic flow patterns in the vicinity of multi-float structures.…”

“…The study of the hydroelastic phenomena in VLFS can be done in either the frequency domain or the time domain. The former assumes a linear response of the transient effects described as a time‐harmonic motion, see for instance References 28‐30. The time‐domain analysis avoids the linear assumption, making it a suitable approach for the analysis of steep wave fronts and cases with highly nonlinear effects 13,31 .…”

In this work we present a novel monolithic Finite Element method for the hydroelastic analysis of very large floating structures (VLFS) with arbitrary shapes that is stable, energy conserving, and overcomes the need of an iterative algorithm. The new formulation enables a fully monolithic solution of the linear free-surface flow, described by linear potential flow, coupled with floating thin structures, described by the Euler-Bernoulli beam or Poisson-Kirchhoff plate equations. The formulation presented in this work is general in the sense that solutions can be found in the frequency and time domains, it overcomes the need of using elements with C 1 continuity by employing a continuous/discontinuous Galerkin approach, and it is suitable for finite elements of arbitrary order. We show that the proposed approach can accurately describe the hydroelastic phenomena of VLFS with a variety of tests, including structures with elastic joints, variable bathymetry, and arbitrary structural shapes.
