• A FINITE ELEMENT METHOD FOR FLUID-STRUCTURE INTERACTION WITH SURFACE WAVES

  E. Oñate, J. García

  Journal of Marine Engineering (2010). Vol. 18, (1)

  
  

  Abstract

  A stabilized semi-implicit fractional step finite element method for solving coupled fluid-structure interaction problems involving free surface waves is presented. The stabilized governing equations for the viscous incompressible fluid and the free surface are derived at a differential level via a finite calculus procedure. A mesh updating technique based on solving a fictitious elastic problem on the moving mesh is described. Examples of the efficiency of the stabilized semi-implicit algorithm for the analysis of fluid-structure interaction problems in totally or partially submerged bodies is presented.

• A FEM fluid-structure interaction algorithm for analysis of the seal dynamics of a Surface-Effect Ship

  E. Oñate, J. García-Espinosa, E. Oñate, D. Capua, B. Serván-Camas, P. Ubach

  Journal of Marine Engineering (2016). Vol. 18, (1)

  
  

  Abstract

  This paper shows the recent work of the authors in the development of a time-domain FEM model for evaluation of the seal dynamics of a surface effect ship. The fluid solver developed for this purpose, uses a potential flow approach along with a stream-line integration of the free surface. The paper focuses on the free surface-structure algorithm that has been developed to allow the simulation of the complex and highly dynamic behavior of the seals in the interface between the air cushion, and the water.The developed fluid-structure interaction solver is based, on one side, on an implicit iteration algorithm, communicating pressure forces and displacements of the seals at memory level and, on the other side, on an innovative wetting and drying scheme able to predict the water action on the seals. The stability of the iterative scheme is improved by means of relaxation, and the convergence is accelerated using Aitken’s method.Several validations against experimental results have been carried out to demonstrate the developed algorithm.

• Non-linear dynamic analysis of the response of moored floating structures

  J. García-Espinosa, B. Zamora-Parra, J. Gutiérrez-Romero, B. Serván-Camas

  Journal of Marine Engineering (2002). Vol. 18, (1)

  
  

  Abstract

  The complexity of the dynamic response of offshore marine structures requiresadvanced simulations tools for the accurate assessment of the seakeeping behaviourof these devices. The aim of this work is to present a new time-domain model forsolving the dynamics of moored floating marine devices, specifically offshorewind turbines, subjected to non-linear environmental loads. The paper first introducesthe formulation of the second-order wave radiation-diffraction solver, designedfor calculating the wave-floater interaction. Then, the solver of the mooringdynamics, based on a non-linear Finite Element Method (FEM) approach, is presented.Next, the procedure developed for coupling the floater dynamics model with themooring model is described. Some validation examples of the developed models,and comparisons among different mooring approaches are presented. Finally, anstudy of the OC3 floating wind turbine concept is performed to analyze the influenceof the mooring model in the dynamics of the platform and the tension in the mooringlines. The work comes to the conclusion that the coupling of a dynamic mooringmodel along with a second-order wave radiation-diffraction solver can offer realisticpredictions of the floating wind turbine performance.
