Definitions

  • This invention relates to a barge for disposing of oil slicks. It is known to contain a floating oil slick by means of an elongate floating wall which may be made of netting or of imperforate material and which is towed behind a vessel.
  • the object of the invention is to provide a barge for use with such elongate floating walls and for collecting the floating oil contained by such walls.
  • a barge for disposing of oil slicks comprising a bottomless hull composed of buoyant walls enclosing a space, and transfer means having an inlet for drawing in oil from outboard of the hull at the forward end thereof and an outlet for discharging into the space.
  • Fig. 1 ia a diagrammatic plan view of a barge according to the invention
  • Fig. 2 is a diagrammatic longitudinal sectional view of the barge in Fig. 1
  • a barge comprises a bottomless hull composed of buoyant walls, i.e. a forward wall
  • Transfer means in the form of a pump 6 is housed in the wall 1, having an inlet 7 and an outlet 8.
  • a fully swivellable thruster 9 mounted outboard of the hull on the wall 2 is a fully swivellable thruster 9. The pump 6 and the thruster 9 are driven from a prime mover 10 supported above the space 5 and spanning between the walls 3 and 4.
  • the prime mover 10 may comprise a diesel engine and a hydraulic power unit.
  • the pump 6 may be of variable capacity and/or speed.
  • an endless conveyor belt having an upper run rising upwards and rearwards at a shallow angle from a location outboard the forward end of the hull and provided with pockets for carrying oil for discharge into the space 5.
  • the barge is towed behind two vessels (not shown) spaced apart line abreast, via two elongate floating walls represented by the broken lines 11 and 12
  • the two vessels follow a course towards an oil slick and on respectively opposite sides thereof so that the oil slick becomes contained between the floating walls 11 and 12.
  • Sea water and oil are drawn in via the inlet 7 and discharged into the space 5.
  • the sea water and oil become calm and the oil floats in a gradually deepening Layer 13 which displaces the sea water out through the open bottom of the hull.
  • ballasting of the barge plays no part in ballasting the barge but ballasting of the barge to suit sea conditions can be achieved by making the walls 1,2,3 and 4 hollow and introducing sea water into the hollow or removing it therefrom. Additionally, the height of the inlet 7 can be adjusted to the outboard sea level.
  • the thruster 9 is provided to correct for any drifting of the barge.
  • the barge need not be manned since all necessary controls can be performed by radio from one of the towing vessels.

Abstract

Une péniche est destinée à être remorquée derrière deux navires écartés en ligne de front, par l'intermédiaire de deux parois flottantes allongées (11, 12). La péniche possède une coque sans fond composée de parois flottantes (1, 2, 3 et 4) renfermant un espace (5). Une pompe (6), par exemple, est montée à l'extrémité avant de la coque pour transférer l'huile depuis une nappe d'huile contenue entre les parois flottantes allongées (11, 12) dans l'espace (5) où la nappe flotte en formant une couche de plus en plus profonde (13) en déplaçant l'eau de la mer au travers du fond ouvert de la coque.
