Title (EN) METHOD AND APPARATUS FOR OIL SKIMMING
(FR) PROCEDE ET APPAREIL DE RAMASSAGE EN SURFACE DU PETROLE
Abstract:
(EN) Method and apparatus for removing oil from water surfaces including a self-propellable vessel having a catamaran type hull (10, 12) defining an oil collection channel (16) therebetween through which is advanced a series of loosely supported, parallel flexible rope belts (38) of floating oil collecting material which are moved countercurrent to the direction of vessel advance at substantially zero differential velocity relative to the water surface to pick up the oil on the surface. The rope belts (38) float freely on the water surface and are free to move vertically and longitudinally under the action of the water. Lateral deflection of the ropes under the action of debris or other obstruction is also possible. The free floating nature of the flexible belts (38) prevents adverse headwaves from being formed at their initial contact with the water surface and allows relatively high vessel speeds.
(FR) Procede et appareil pour prelever le petrole de la surface de l"eau comprenant un navire autopropulse dont la coque (10, 12), du type catamaran, definit, entre ses deux elements, un canal (16) de ramassage du petrole. Une serie de bandes continues (38), flexibles, disposees parallelement entre elles et maintenues de facon lache, constituees d"un materiau se pretant au ramassage du petrole flottant, sont mues dans le canal (16) dans la direction opposee au mouvement du navire de facon telle que leur vitesse par rapport a la surface de l"eau soit sensiblement nulle afin qu"elles puissent operer le ramassage du petrole a la surface. Les bandes (38) flottent librement sur la surface de l"eau et sont libres de se mouvoir verticalement et longitudinalement sous l"action de l"eau. Le deport lateral des bandes sous l"action des debris ou d"autres obstacles est egalement possible. Le fait que les bandes flexibles (38) puissent flotter librement permet d"eviter l"effet contraire du a la creation de vagues d"etrave lors du contact initial avec la surface de l"eau et autorise des vitesses de deplacement du navire relativement elevees.
