Abstract

L'INVENTION CONCERNE UN SYSTEME ET UN APPAREIL POUR LA POSE ET L'ENFOUISSEMENT SIMULTANES D'UN PIPELINE SOUS-MARIN, A PARTIR D'UN BATEAU, AU FUR ET A MESURE DE SON ASSEMBLAGE SUR CELUI-CI. L'APPAREIL COMPREND UN CHASSIS RIGIDE MUNI DE PATINS, EN CONTACT AVEC LE FOND DE LA MER PENDANT LA PROPULSION, ET PORTANT UNE CHARRUE AVEC UNE LAME DE CISAILLEMENT A L'AVANT POUR AMORCER LE CREUSEMENT DE LA TRANCHEE. LA POSITION DE LA CHARRUE EST REGLABLE. UN AGITATEUR, SUIVANT LA CHARRUE DANS L'AXE DE LA TRANCHEE, MET LES SEDIMENTS EN SUSPENSION AVANT LA POSE DU PIPELINE POUR EMPECHER LEUR RETOMBEE PREMATUREE. DES ELEMENTS VERTICAUX SUPPORTENT ET GUIDENT LE PIPELINE ENTRE LE BATEAU OU IL EST ASSEMBLE ET LA TRANCHEE DANS LAQUELLE IL EST DEPOSE, TANDIS QUE LE CREUSEMENT SE POURSUIT DE MANIERE CONTINUE DANS UNE OPERATION COMBINEE. APPLICABLE AU TRANSPORT DE PRODUITS RECUEILLIS AU LARGE PAR EXEMPLE PRODUITS PETROLIERS.
