Abstract

Procédé et dispositif pour la collecte des hydrocarbures H répandus sur les plans d'eau en vue de leur relevage, dans lequel au moins un élément de drague flottante 1 est remorqué par un remorqueur 2, de telle sorte qu'il présente une composante de vitesse Vn normale à sa paroi afin de balayer la nappe d'hydrocarbure H. On maintient la paroi de la barrière 1 avec une inclinaison i suffisamment faible relativement à la direction K du remorquage pour éviter l'apparition, contre la paroi de la drague, de pressions hydrodynamiques génératrices de vortex, tout en évitant d'entraîner à vitesse élevée la nappe d'hydrocarbure épaissie par rapport à l'eau sous-jacente. Le contrôle de i est assuré par une traction T orthogonale à K à l'extrémité arrière B de l'élément 1. Application à la dépollution de la mer, en haute mer, dans les baies ouvertes ou fermées et dans les estuaires ou embouchures des rivières côtières.
