Abstract

L'invention se rapporte à un dispositif d'ancrage évitant la détérioration des conduites sous-marines pouvant se trouver sur le lieu d'ancrage. A cet effet les corps morts 6 descendus verticalement au moyen des câbles 7 commandés par les treuils 8 sont des corps déformables. En outre, lors du pilonnement ou d'un déplacement de l'engin 1 les corps 6 exercent par leur soulèvement partiel un accroissement progressif de la tension des câbles 7 évitant les à-coups. L'invention s'applique notamment aux ancrages en eaux peu profondes dont le fond comporte des conduites d'écoulement de produits pétroliers.
