Hydroelastic Response to the Effect of Current Loads on Floating Flexible Offshore Platform

An analytical model of a current load's interaction with a moored floating flexible structure based on the Timoshenko-Mindlin beam theory is developed under the assumption of small-amplitude wave theory and the structural response. Theoretical solutions on the displacement of the structure, reflection, and transmission coefficients are obtained by applying the matching technique along with the orthogonal model coupling relation. The results of the transmission coefficient and displacement amplitude are compared with the other calculations and experimental datasets available in the literature. The structural deflection and transmission coefficients are investigated via the hydroelastic response for wave-current loads along with design parameters. The comparison results showed that the present model result is supported by the numerical model's results. This present analysis can provide further information for marine engineers to design floating flexible platforms in the marine environment.

Automated summary

An analytical model of the interaction between a current load and a moored floating flexible structure was developed using the Timoshenko-Mindlin beam theory. Theoretical solutions for displacement, reflection, and transmission coefficients were obtained using the matching technique and orthogonal model coupling relation. The results were compared with calculations and experimental data from literature, and were found to be consistent with a numerical model. This analysis can provide valuable information for marine engineers designing floating flexible platforms in the marine environment.
