  1. 15-19 th May IOSC 2005 Experimental Numerical and Optimisation Study of Oil Spill Containment Boom F. Muttin, S. Nouchi Ecole d’Ingénieurs en Génie des Systèmes Industriels La Rochelle, France.

  2. Partnership • SIMBAR project http://simbar.eigsi.fr • EIGSI - Structural analysis • La Rochelle University – Hydrodynamic bassin • EDF R&D – Fluid Flow analysis • CEDRE - Expertise & Industrials aspects • CETMEF – French Ministry coastal protection • RITMER Network www.ritmer.org/fr/index.html • MEDD French Governement grant n°CV03000142

  3. Geometry and Stress V=0.5 m/s Up side Down side

  4. Geometry and stress V=0.3 m/s Float & skirt only reinforcement bottom skirt q 7.6 add a bottom skirt chain q -22.5996 add more a top skirt leech

  5. Geometry and stress With chain V=0,4 m/s θ -36° With chain and leech V=0,3 m/s q -31°

  6. Boom Conception Variation

  7. Skirt Angulation q q (s)

  8. Boom Section of 150 m,V = 0.3 m/s Geometry of sections (without chain): Central skirt angulation 4° Stress: Up-stream Down-stream

  9. Complete boom contingency plan 750 m Provisory Geometry, coffers fixed Provisory Internal Stress, coffers fixed Provisory Geometry, without anchorage system

  10. Hydrodynamic • CEDRE – polludrome visualisation test • LNHE – SPH numerical method Doc. CEDRE Doc. LNHE EDF

  11. Structural computations • L 30 m V 0.3m/s Stress balance during iteration solutions boom without skirt bottom chain

  12. Conclusion • Boom modelling (coastal fluid flow Telemac2D) • Coastal zone-test choice • Industrial progress implementation
