Abstract
Device for laterally shifting an assembly of apparatuses such as seismic streamer towed behind a ship, with respect to the ship route, comprising a profiled wing, connected to the assembly through a single cable, at the lateral end parts of which are formed two profiled caissons and whose central part therebetween is thinner and is provided in the middle with a profiled central rib extending from the leading edge to the trailing edge of the wing and protruding downwardly at said last edge beyond the height of the caissons.
Claims6
A device for laterally shifting an assembly towed in a fluid through a towing cable by a vehicle, with respect to the trajectory thereof, comprising a profiled wing connected to said towed assembly, whose leading edge is rounded and whose forward side bearing on operation, on the fluid and the opposite rear side have convex portions, said device being connected to the towed assembly through a single cable and comprising two hollow caissons defined by the walls of the wing, said caissons being respectively located at the two opposite ends thereof, and being separated by a thinner central portion concave on the forward side of the wing, and said central portion being oriented perpendicularly to the leading edge, the device also comprising a profiled central rib, in the middle of said concave central portion, extending from the leading edge to the opposite edge, the height of the central rib at said opposite edge being greater, at said edge, than the thickness of the wing.
