  Presentation held at the second public workshop of the FIBRESHIP project, held at La Ciotat, France, on 25th of June 2019. The second public workshop of the FIBRESHIP project offered to the participants a chance to discuss the different composite materials solutions for shipbuilding as well as learn more about the latest technological advances of FIBRESHIP Project related to design, construction and operation of ships integrally built in composite materials. FIBRESHIP Consortium is looking for a niche in the future shipping market through promoting changes in the regulatory framework of IMO and generating guidelines and methodologies for designing, building and operating large-length vessels, laying the foundations of a new market based on composites technology in shipbuilding and shipping. In this presentation, Txuma Iturgáiz on behalf of MTorres introduced the field of activity of his company which is focused on the development of new innovative machines with a high level of automatization for manufacturing and testing composite laminates. Txuma suggested that the most advanced technologies for composite manufacturing can be applied for the shipyards in the construction of a new generation of lightweight ships with the advantages of reasonable cost, flexibility and outstanding quality, extrapolating the advances reached in aeronautical and automotive sectors.

This presentation explains the development of a new software suite with a wide variety of ad-hoctools to simulate the structural and fire performance of the lightweight composite ships developed within the FIBRESHIP project. The computational analysis tool is based on a fast-numerical software which can be used for the simulation of fatigue, fire diagnosis, thermal propagation, hydro-structural analysis and so on. A Betha version of the developed software suite of this numerical tool is available for the partners of the project.

  Abstract

  Presentation held at the second public workshop of the FIBRESHIP project, held at La Ciotat, France, on 25th of June 2019.   The second public workshop of the FIBRESHIP project offered to the participants a chance to discuss the different composite materials solutions for shipbuilding as well as learn more about the latest technological advances of FIBRESHIP Project related to design, construction and operation of ships integrally built in composite materials. FIBRESHIP Consortium is looking for a niche in the future shipping market through promoting changes in the regulatory framework of IMO and generating guidelines and methodologies for designing, building and operating large-length vessels, laying the foundations of a new market based on composites technology in shipbuilding and shipping.   This presentation is dedicated to the strategies of regulatory and standardization activities of the project, mainly focused on the fire challenges related to the use of composites in the shipping industry. Reddy Devalapalli (Lloyd’s Register of Shipping) explained that a presentation in collaboration with RAMSSES project is being prepared for the next SDC of IMO in February 2020 as well as a info paper, to promote changes in the current regulatory frameworks which limit the use of Fibre Reinforced Plastic elements in the construction of large-length ship structures. In addition, Stephane Pabeouf from Bureau Veritas described the development of new performance criteria which will attempt to deal with the fire safety issues and structural performance of the new lightweight ships, being an essential part of the FIBRESHIP project.

• A Second Order Semi-Lagrangian Particle Finite Element Method for Fluid Flows

  J. Colom Cobb, J. García-Espinosa, B. Servan Camas, P. Nadukandi

  Computational Particle Mechanics (2020). 7, 3–18

  
  

  Abstract

  In this paper, a second order SL-PFEM scheme for solving the incompressible Navier-Stokes equations is presented. This scheme is based on the second order velocity Verlet algorithm, which uses an explicit integration for the particle’s trajectory and an implicit integration for the velocity. The algorithm is completed with a predictor-multicorrector scheme for the integration of the velocity correction using the Finite Element Method. A second order projector based on least squares is used to transfer the intrinsic variables information from the particles onto the background mesh, while a second order interpolation scheme is used to transfer the accelerations from the mesh to the particles. Convergence analyses are carried out to assess the second order convergence.

• A finite element method for fluid-structure interaction with surface waves using finite calculus formulation

  E. Oñate, J. García-Espinosa

  (2001). Research Report, Nº PI208

  
  

  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.

• Ship hydrodynamics

  E. Oñate, J. García-Espinosa, S. Idelsohn

  (2003). Research Report, Nº PI222

  
  

  Abstract

  This chapter presents an overview of some computational methods for analysis of ship hydrodynamics problems. Attention is focused on the description of a stabilized finite element formulation derived via a finite calculus procedure. Both arbitrary Lagrangian-Eulerian (ALE) and fully Lagrangian forms are presented. Details of the treatment of the free-surface waves and the interaction between the ship structure and the sea water are also given. Examples of application to a variety of ship hydrodynamics problems are shown.

• A general stabilized formulation for incompressible fluid flow using finite calculus and the finite element method

  E. Oñate, J. García-Espinosa, G. Bugeda, S. Idelsohn

  (2003). Research Report, Nº PI223

  
  

  Abstract

  We present a general formulation for incompressible fluid flow analysis using the finite element method (FEM). The necessary stabilization for dealing with convective effects and the incompressibility condition are introduced via the so called finite calculus (FIC) method. The extension of the standard eulerian form of the equations to an arbitrary lagrangian-eulerian (ALE) frame adequate for treating fluid-structure interaction problems is presented. The fully lagrangian form is also discussed. Details of an effective mesh updating procedure are presented together with a method for dealing with free surface effects of importance for ship hydrodynamic analysis and many other fluid flow problems. Examples of application of the eulerian, the ALE and the fully lagrangian flow descriptions are presented.

• Development of a new FEM code for ship hydrodynamics analysis. Applications to the design of America's Cup yachts.

  E. Oñate, J. García-Espinosa

  (2004). Research Report, Nº PI257

  
  

  Abstract

  The objective of the project that is presented at the IV Prize Duran i Farell Award for Research and Technology is the development of a new computational code based on the finite element method for the fluid-dynamics analysis of vessels. The code allows to accurately reproduce the model basin tests (MBT) usually used for the experimental evaluation of the hydrodynamic resistance of ships. The new code, called Tdyn, is a much more economical and precise alternative to model basin tests, by allowing the analysis of the behavior of vessels in real scale, thus eliminating the usual scale errors in the experimental tests. Tdyn incorporates new mathematical models and advanced finite elements methods that have led to numerous international publications. Tdyn was jointly developed by researchers from the Technical University of Catalonia (UPC) of the Department of Strength of Materials and Structural Engineering of the Barcelona School of Civil Engineering and of the Department of Nautical Engineering and Science of the Faculty of Nautical Studies of Barcelona in the framework of several European and national projects carried out in collaboration with the research center CIMNE and the company Compass IS, as well as other prestigious companies in the naval architecture sector. Tdyn was applied to the design of several America’s Cup yachts (in particular, of the ALINGHI team, winner of the 2003 edition). Tdyn is currently commercialized worldwide through Compass IS, a spin-off of the UPC.
