A unitized marine umbilical cable carrying any number or combination of conventional elements such as hoses and electrical cables. A center stress member disposed along the axis of the marine umbilical cable is capable of supporting an underwater device such as a diving bell should the primary down line break. Cylindrically surrounding the stress member is a compression extrusion of a high strength highly resilient elastomer around which are helically cabled various conventional elements. Within the interstices between the high strength elastomer and the helically cabled elements is a resilient fill material. The resilient fill material and high strength highly resilient, low durometer elastomer serve as a radial shock absorber against tensional impact upon the umbilical or radial forces thereupon.
