The invention relates to a system for the mass recovery of petroleum products which is installed on a boat (1) that is specially designed to approach the oil slick to be recovered at 20 knots, said slick having been enclosed by a containment barrier comprising a skirt that prevents the petroleum from escaping underneath. The recovery system comprises a static ramp (10, 11) that extends into the sea to a sufficient depth in order to take account of very strong swells, the upper end (12) of said ramp being solidly connected to a dynamic decantation tank (2, 3) which is closed on top by means of a wall (4, 5). The boat loads the petroleum and water by means of the ramp (10, 11) into the tank thereof (2, 3) serving as a static water/petroleum separator, in which the oil slick (13), which has a lower density than water (14), floats on the water, thickening on top of the surface (15). The upper level (16) of the slick is always maintained below that (17) of the level of the sea by means of a centrifugal pump assembly (18) having an adequate capacity. Said pump assembly expels the water (14) into the sea so that petroleum and water can continue to be loaded. When the lower level of the slick (13) falls below the transfer pumps (19), benefiting from the gravitational pressure of the slick, said transfer pumps start up and push the slick, via a separation wall (6, 7), into a storage tank (8) for decanted oil, while the boat advances into the slick at a maximum speed of approximately six knots.

Le système de récupération en masse de produits pétroliers est installé sur un navire (1) spécialement agencé pour approcher à 20 noeuds la nappe de pétrole à récupérer, préalablement cernée d'un barrage de confinement comportant une jupe évitant les fuites de pétrole par dessous. Le système de récupération est constitué d'une rampe statique (10, 11) plongeant dans la mer à une profondeur suffisante pour tenir compte de très fortes houles et dont l'extrémité supérieure (12) est solidaire d'une soute de décantation dynamique (2, 3) fermée au-dessus par une paroi (4, 5); le navire embarque, par l'intermédiaire de sa rampe (10, 11), le pétrole et de l'eau dans sa soute (2, 3) jouant le rôle de séparateur statique eau/pétrole, dans laquelle la nappe de pétrole (13), de densité plus faible que l'eau (14) flotte sur elle en s'épaississant au-dessus de sa surface (15). Le niveau supérieur (16) de la rampe est maintenu toujours inférieur à celui (17) du niveau de la mer, par un ensemble de pompes centrifuge (18) de capacité adéquate, expulsant à la mer l'eau (14) pour continuer à permettre l'embarquement de pétrole et d'eau, lorsque le niveau inférieur de la nappe (13) descend en-dessous de pompes de transfert (19), bénéficiant de la pression gravitationnelle de la nappe, celles-ci se mettent en marche et la refoule, au travers d'une paroi de séparation (6, 7), dans une soute de stockage (8) de pétrole décanté, pendant que le navire avance dans la nappe à une vitesse maximale d'environ six noeuds.
