ABSTRACT:
A flexible conductor adapted for use as a "marine riser" in offshore drilling and production operations. The conductor includes a central flexible elastomer portion connected at each end with a rigid tubular portion. Disposed in the elastomer portion are inner and outer reinforcing members for containing the pressure differential across the central portion and for carrying the compressive loads. A plurality of circumferentially spaced longitudinally extending metal wires are disposed in the central portion between the inner and outer reinforcing members for enabling flexing of the central portion while carrying the tension load on the flexible conductor. The longitudinally extending wires are secured to the end portions by threaded retainers for ease of assembly.
