Definitions

  • the present invention relates to a floating product recovery vessel.
  • Such a device may for example have walls forming a funnel, which block the surface layer of water and protrude above the surface of the water, to push this layer directly towards the recuperators.
  • concentration devices arranged in front of the recuperators to attract floating products to these recuperators.
  • Such a device may for example have walls forming a funnel, which block the surface layer of water and protrude above the surface of the water, to push this layer directly towards the recuperators.
  • Such a device is described in document US-A No. 3,701,430 (Tuttle).
  • the object of the present invention is to facilitate the recovery of floating products by attracting the layer of surface water towards the plating of the boat.
  • the angle of incidence of the wing is between 15 ° and 35 °
  • the span of the wing is between half and double its cord
  • the distance from the trailing edge of the wing at the recuperator is at least equal to half the span of the wing, so as to allow said lateral call for surface water to bring the floating products from the end of the wing to in the recuperator
  • the wing is in the shape of a delta wing, the leading edge of which progressively deviates laterally from the hull from the bow of the ship so as to favor the formation of a vortex with a substantially horizontal axis along relative to the ship, this vortex taking the water below the level of the wing behind it, bringing it up to the surface on the outer edge of the wake of the wing and bringing it back to the hull on the surface in the wake of the wing.
  • a first floating product recovery vessel provided with a device is intended for the collection of polluting products such as hydrocarbons.
  • Its hull is shown in 2. It has two recuperators 4 arranged symmetrically on both sides of the hull, and sucking a surface layer of water, on an adjustable height such as for example 10 cm.
  • Two devices for attracting floating products are arranged symmetrically on either side of the bow of the ship. Each is in the form of a plane wing 6 in "delta" shape placed in positive incidence.
  • the wing may have a rectangular shape which is that of the wing 16 fixed on the hull 12 of a second vessel equipped with recuperators 14 (FIGS. 4 to 6).
  • means are provided for removing the wing (6) so as to allow an easier advance of the ship when there are no floating products to attract against the hull.
  • these means are constituted by a lifting chain 20, the delta wing 6 being provided with hinges 24 arranged near the hull and making it possible to raise it to an almost vertical position represented in 6 ′.
  • a pole 22 which is articulated on the shell 2 and the other end of which engages a stop provided on the upper surface of the wing.
  • the pole can be raised using a second chain 26.
  • an interior jack allows the rectangular wings 16 to be returned horizontally to the shell 12.
  • the efficiency of the device according to the invention is illustrated in FIG. 1 by lines 10 in dashed lines representing lines of current on the surface.
  • the horizontal bandwidth of recovery efficiency can thus be increased, for example, to twice the width of the ship.
