Special Issue Information

Dear Colleagues,

We are inviting submissions to the Special Issue ‘Hydroelastic behaviour of Floating Offshore Structures. This Special Issue is navigated by the increase in the use of floating offshore structures for various applications such as large floating platforms, the floating base for aquaculture, and large-capacity oil storage tanks. Therefore, the hydroelastic behaviour of floating offshore structures in terms of their vertical displacement and structural deformations of n-modes are necessary to access their efficiency and survivability from the structural damages as the offshore floating structure locates in unprotected open waters and exposed to the rigorous environmental condition.

This Special Issue will focus especially on models based on the novel, latest, and allied developments in floating offshore structures in the area of hydroelasticity. Submissions will be addressed by the theoretical modeling, numerical modeling, and prototype testing as applications in offshore base.

Contributions introducing the non-linear wave effect on the hydroelastic response of floating structures based on theoretical, numerical, and experimental models are particularly welcomed.

Taking into consideration the above-mentioned features, this Special Issue will include, without being limited to, the following topics of interest:

  • Theoretical model for floating oil-storage tank;
  • Floating structure with hinges plates;
  • Analytical and numerical model;
  • Hydroelastic behavior of floating fish cage;
  • Nonlinear hydroelastic model;
  • Hydroelastic of the offshore wide turbine;
  • Model tests of floating pontoon.

The paper considers the visco-elastic response of the ice cover in a channel under an external load moving with constant speed along the center line. The channel has a rectangular cross-section with a finite depth and width. The fluid in the channel is inviscid and incompressible and its motion is potential. The fluid is covered by a thin sheet of ice frozen to the channel walls. The ice thickness varies linearly symmetrically across the channel, being lowest at the center of the channel and highest at the channel walls. Ice deflections and strains in the ice cover are independent of time in the coordinate system moving with the load. The problem is solved numerically using Fourier transform along the channel and the method of normal modes across the channel. The series coefficients for normal modes are determined by truncation for the resulting infinite systems of linear algebraic equations. The ice deflections and strains in the ice plate are investigated and compared to the case of constant mean ice thickness. It is shown that even a small variation of the ice thickness significantly changes the characteristics of the hydroelastic waves in the channel. Full article

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. Full article

A hydroelastic model is developed of a floating flexible structure in the presence of a submerged perforated base connected with mooring lines under oblique wave action. Using the velocity decomposition method, the analytical solution of the referred model is obtained in finite water depth. The convergence of the analytical solution for different oblique wave incidences is examined, and the present results of deflection amplitude are compared with experimental datasets and the numerical results available in the literature. The effects of oblique wave incidence, along with various design parameters on the reflection, transmission, and dissipation coefficients, as well as structural displacements, are analysed through hydroelastic analysis. Further, the effect of oblique incidence angle on the free oscillation hydroelastic waves in two wave modes is investigated by deriving the free motion velocity potential in a wave basin.
