Abstract: | This article describes the results of hydraulic model tests of the elastic response of a very large floating structure (VLFS)
moored inside a reef in an isolated island. The distributions of strains and vertical displacements due to the elastic response
of the VLFS were measured. The response characteristics were strongly affected by deformed nonlinear waves inside the reef.
A two-step analytical method to compute the elastic response of a VLFS is proposed, and its validity is verified using the
results of the hydraulic model tests.
