Abstract

DISPOSITIF DE MESURE EN TEMPS REEL DE COURANTS MARINS PAR GRANDS FONDS POUVANT DEPASSER 6000 METRES, EN FONCTION DE LA PROFONDEUR. UN ENGIN E DE FORME SPHERIQUE DE FLOTTABILITE NEGATIVE EST MOUILLE A PARTIR D'UN BATEAU 2 ET DESCEND AU FOND DE LA MER, LARGUE SON LEST ET REMONTE A LA SURFACE OU IL EST RECUPERE. DES BOUEES ACOUSTIQUES REPONDEUSES B, B ET B POSITIONNEES GEOGRAPHIQUEMENT AINSI QUE L'ENGIN RECOIVENT DES IMPULSIONS EMISES PAR LE BATEAU ET REPONDENT AU BATEAU. D'AUTRE PART L'ENGIN ENVOIE EGALEMENT UNE REPONSE DESTINEE AUX BOUEES QUI REPONDENT VERS LE BATEAU; DES TEMPS D'ARRIVEE DE CES IMPULSIONS, UN CALCULATEUR A BORD DU BATEAU CALCULE LES POSITIONS SEQUENTIELLES DE L'ENGIN PAR RAPPORT AUX BOUEES AINSI QUE LES VITESSES DES COURANTS EN FONCTION DE LA PROFONDEUR. APPLICATION A LA TECHNIQUE DE FORAGE EN HAUTE MER POUR LE CALCUL DES EFFORTS SUR LES STRUCTURES.
