Séminaire international "Propulsion par le vent"

Organisé le lendemain de la soutenance de thèse de Florent BICKERT (doctorant au LHEEA sur la performance des navires à propulsion vélique), ce séminaire constituera une occasion rare d'écouter et d'échanger avec plusieurs des meilleur.e.s expert.e.s internationaux du domaine sur la thématique de la propulsion vélique. 

Le séminaire se tiendra intégralement en anglais, avec possibilité de participation sur place ou à distance.

INSCRIPTION OBLIGATOIRE via ce lien avant le 30/11/2026 (et dans la limite des places disponibles)

Programme :

• 9:30. Welcome coffee
• 10:00. How we use aerodynamic open-source tools for holistic modeling of wind powered ships at SINTEF Ocean and NTNU, Jarle KARMER, Senior resercher, SINTEF, Norway.
  The presentation will introduce the actuator-/lifting line library Stormbird, and show how that is used in hybrid experimental testing and together with other more established hydrodynamic simulation tools for "holistic ship modelling", including sea keeping and manoeuvring.
• 10:30. Full scale testing of ships with wind propulsion, Sofia WERNER, Lead researcher, RISE maritime (Research Institute of Sweden), Sweden
  This presentation will cover developing standard procedures for assessing the power saving from wind propulsion. It will discuss challenges,  steps towards standardisation, uncertainties, and some real examples.
• 11:00. LifeCycle Analysis of wind-powered ships, Aurore WENDLING (visio), PhD candidate, Norwegian University of Science & Technology (NTNU), Norway.
  Although pure sailing appears as a very ecological alternative to conventional shipping, relying primarily on the wind for ship propulsion entails a heavy dependency on weather, which implies irregular sailing speeds and overall slower voyages. However, sailing slower means carrying less cargo over the same amount of time, and thus increasing the share of construction, maintenance and end-of-life impacts in transport emissions. Based on a simplified LCA, the presentation will give some hints on the magnitude and relative shares of these impacts for a hypothetical 20 000 DWT sailing vessel with varying levels of motor-assistance. The results will be put into perspective with an estimate of transport costs under several carbon tax scenarios.
• 11:30. Questions & Answers
