  • Flexible floating boom comprising transverse stiffeners of variable stiffness
    Patent number: 4430955
    Abstract: This floating boom comprises a flexible structure forming a barrier provided with transverse stiffeners to which are secured floats adapted to support this structure in a substantially vertical position in water. The stiffeners are designed so as to be resiliently bent at their lower part under the action of the water current for a velocity of the water current sufficient to cause bending without causing any substantial change in the inclination of the remainder of the boom in water.

  • Floating boom structure
    Patent number: 4398844
    Abstract: This floating boom comprises a flexible structure forming a barrier equipped with transverse stiffeners to which are secured floats adapted to support the flexible structure in a substantially vertical position in water. Each stiffener forms a buoyant unit with the floats secured thereto. The successive buoyant units are interconnected by an assembly of articulated linking rods longitudinally extending along the upper part of the boom. These longitudinal rods support the flexible structure which forms a barrier.
