Abstract: Paravane for floating barrier A paravane (20) including at least one foil with a first side, a second side, a leading end, a trailing end, a top and a bottom, wherein at least one foil is straight (1) and at least one second foil is curved (2), where one side of the straight foil and the other side of the curving foil are interconnected by a number of stays (3), where at least one foil is connected at the top to at least a first buoyant body (10) and that at least the one plane at the bottom is connected to at least one ballast element (13), and that at the second side of the straight foil there are at least one towline (8) and a tow eye (9) by which there is achieved a paravane (20) that can keep an arrangement of lines, nets, floats in a water body in a position suitable for performing the task.

Abstract: The invention concerns one or more floating barriers for use together with a conventional floating barrier for use in collecting oil on a water surface. The floating barriers are of the kind where the submerged part is partially penetrable for water and oil, thereby providing an impeding but not blocking effect on a passing flow of water. The function of the floating barriers is based on the fact that by disposition upstream relative to the conventional floating barrier and together with the latter they will constitute a total system which can be moved through an oil-contaminated body of water with substantially greater speed than a conventional floating barrier, without leaking oil behind the floating barrier system. The invention particularly concerns conditions of the geometry, spacing and draught of the water-penetrable liquid barriers.
